Original subtitles

NARRATOR: Firearms officers serving West Yorkshire Police

are arresting a man outside his home in Leeds.

A woman has been stabbed.

Forensic teams are dispatched to the scene.

The stabbing is in a basement flat in Headingley.

The victim has been rushed to hospital by medics

to try and save her life.

Forensic crime scene manager jasmine White

is briefed by the first officers to arrive on the scene.

So, once we've arrived, ambulance have been called, six,

and they've been doing CPR.

So the female is laid, essentially, in the doorway

of the front of the address. CPR is ongoing.

Um, extensive bleeding,

which can be seen throughout the whole of the room.

Um, so, whether she was found like that,

whether she'd been moved in some capacity, I'm not sure.

Is it a shared flat? Yes, it is. It's a one-bedroom flat.

However, um, our victim has been staying

in what is classified as the living room.

So that's the front room, as soon as you walk in.

Ancl you'll see a mattress to the left-hand side,

and that's been her bedroom.

Police call the period

straight after a serious crime "the golden hour",

the optimum time to gather forensic evidence.

That could be hers, I would think.

But it's been cut off her, aren't it?

So I don't know if that's them.

We found a T-shirt out here that's...

Think it's likely to be the victim's.

I can see it's been cut.

I'm not sure whether it's been cut by paramedics

or whether it's stab wounds ancl she was wearing it at the time.

The forensic team must gather as much evidence as possible

before the weather washes away vital clues.

I'd quite like to get that recovered now.

Excellent.

The victim rents a room in a shared flat.

We have got quite a lot of blood around.

We've got sort of really thick, congealed blood here over this side.

Ancl then we've got some more sort of

what looks diluted blood on the sofa.

Ancl we've also got something that's going up the wall.

It's hard for me to say what that might be.

We've got quite a lot of footprints in blood.

But we're mindful there's been an awful lot of people coming in here.

Um, paramedics, police.

But obviously, what we're interested in is the suspect's footprints.

Um, which is why we're using the stepping plates

to protect the floor.

We've got quite a lot of spatter on the floor as well,

but that could be from the incident.

It could be post-incident.

There's a chair on the bed.

The bed looks a bit dishevelled, but other than that,

pretty much everything else looks neat and tidy.

It's making me wonder.

Like, it's not like there's been a struggle to the point

where everything's thrown everywhere and there's things knocked over.

It all seems very concentrated to just this area.

Yeah, I think this black thing is part of a bra

and the other bits behind me.

I don't know where the rest of her bra is

unless it's on her.

The victim dies in hospital from a suspected stab wound.

The lady has been treated at the scene

and then taken to Leeds General Infirmary,

where she's been pronounced deceased.

This is now a murder investigation.

The on-duty senior detective arrives at the scene.

Be careful. I mean, it's so slippy.

This is where all the congealed blood is.

We've managed to document the blood, make an interpretation of the scene.

It's quite tidy as a scene.

It's gonna have a look in the kitchen.

I've been asked to sort out a CSI for the deceased at hospital

because she needs to be examined, photographed,

forensically recovered for a forensic postmortem.

The evidence gathered by forensics

will inform the investigation by the homicide team.

There's no sign of blood

or any disturbance in the kitchen, bathroom.

I would say other than obviously this,

everything else looks pretty tidy.

Doesn't seem like there's been a sign of a prolonged struggle.

No.

Cos I feel like there's quite a lot of things

that could have been pulled over, knocked over,

and there's just nothing.

Were the keys already there? When I came in, yeah. All right, OK.

No sign of forced entry? No.

It is evidence of, like, a... A man's room.

There's a mobile phone over here, isn't there?

One mobile phone is found at the scene.

It belongs to the lodger in the room next door.

Is that Wi-Fi? Yeah.

The victim's phone is missing.

There's leads for an iPhone there, but I've not seen...

There's just one in there, isn't there? Yes.

So far, there's no sign of a crucial element.

The murder weapon.

It's got vegetables on it.

From the victim's wounds,

the team are focusing on the search for a large knife.

'Working towards the hypothesis that it was a knife.

'That's what I needed to be looking for,

'but keeping an open mind if it was any other weapon.'

Looks interesting.

Be interested to know whether he's come with a knife

just to do that instant.

NARRATOR: A woman in Leeds has been murdered

in a vicious stabbing in her own home.

The Homicide and Major Enquiry Team gathers for its first briefing,

led by Detective Superintendent Emma Winfield.

Good morning, everybody. Thank you for joining us so quickly.

So, at 19:20 last night, I received a call notifying me

of a potential murder and awaiting further information.

An injured party had been transported to LGI.

So, I went to the hospital

to understand our victim and the injuries.

Our victim is Harleen Kaur.

She has long, dark hair.

There was matting of blood in her hair,

but we couldn't see any injuries to her head.

There was obviously medical intervention

that had been stitched up,

and then she had the stab wound to the top of her left breast.

Her hands did have cuts,

slice marks to both hands on her fingers,

which I'd identify as self-defence marks.

The forensic lead, Kate Whitehead,

works alongside the detectives and brings them up to speed.

So, Kate, what's been done so far?

So far, they've been in and taking general photographs.

There are some footwear marks in blood.

Clothing, the T-shirt and the bra has been recovered.

Ancl the iPhone in the rear bedroom has been swabbed and seized.

No major disturbance elsewhere in the flat,

and two knives were noted in the kitchen,

but no obvious blood staining on those.

The deceased at LGI,

the victim, she has been photographed.

Clothing seized and bagged.

As forensic practitioners,

we do work and are employed by the police,

but we have to remain impartial.

'We're there to find, recover and collect evidence

'that might prove somebody's involvement in the case.

'But it also might disprove their involvement in the case.

'So we have to be really unbiased.'

The initial 999 call came in from the lodger

who lives in the room next door to the victim.

So, at 18:27, police were contacted by a witness,

and he reports an ongoing fight at that address.

Ancl he lives in the shared house and is in the basement flat.

The police quickly rule out any relationship

between the lodger and Harleen Kaur.

But he names a potential suspect,

and a firearms team is immediately dispatched to the suspect's flat.

The address linked to the suspect,

which the suspect was arrested from,

is a first-floor flat.

Firearms officers have gone in to clear that address.

They found a bloodied knife.

I intend to have senior CSI go back today,

and myself will have a bit of a closer look at the blood staining.

Suspect has been photographed, had samples taken.

We've also photographed the bottom of his footwear

to see if it marries up with the footwear in the address.

The case has been assigned to Detective Inspector Amanda Sykes,

who'll now take over the investigation.

Thanks, guys. Right. We'll come back to you in a bit.

Thank you very much.

With the suspect in custody,

a full forensic search of his flat is ordered.

We're looking for blood transfer from the main scene.

We're looking for a weapon,

and the suggestion there could be a knife

on a coffee table in there.

Mobile phones, again, if we see those in the scene,

they'll be recorded, swabbed and recovered

cos we need to get the user's DNA off of them.

The area outside the flat is also meticulously searched.

Done? Yeah, nothing. OK.

Brilliant. Excellent. Nothing in there, I take it? Nothing.

Brilliant. Thanks, Mick. Cheers for that.

You all right with this bit here?

Yeah. We'll move our kit across.

Blood-stained knife. Second knife.

So we got the knife pack.

It's like the shapes there fit those two knives.

So there's one, two, three, four, two knives there, two there.

Scissors there. Scissors there. Got them three pins through angles.

Not much there, I think.

So has he gone shopping for a new set of knives?

If we do recover a murder weapon,

one of the most important things that we try and do

is to link the victim and the suspect to that same weapon.

'If we can do that through DNA or fingerprints, that's ideal.'

Well, if we get the victim on the blade and him on the handle,

I think, yeah...

Ancl a mobile phone. Is that stained there?

Yeah, I think this phone looks like it's blood contaminated as well.

So it might be worth not swabbing it as it might want...

A bit more work on it.

Ancl then we've got a couple of destroyed mobile phones,

and there's some blood staining on the back of this one.

Oh, right. OK.

Yes. And I wonder if one of these is her phone.

We won't do any form of disruptive search.

We'll leave that for follow-up.

We'll just deal with what's in front of us.

Like a jigsaw puzzle.

I think that screen goes with that.

That lot goes with that screen. Mm-hm.

With key items recovered for testing in the lab,

forensic blood pattern analysts arrive at the victim's flat.

The interpretation of the patterns of blood

that are present at the crime scene can tell us a lot.

'There may be contact staining,

'which is where a person or an item has made contact with a surface.

'There might be blood drips and a trail which can be followed.

'There might be splatter,

'which is suggestive of impact strikes into wet blood.

'There might be expirated blood,

'which is where somebody has breathed out

'when they've got blood in their chest cavity.

'So the presence of blood at the crime scene is quite basic,

'but it's all the interpretation that comes after that

'that help paints a picture and the story

'of what's gone off at that crime scene.'

Laura Lewis is a forensic biologist

specialising in blood-spatter analysis.

So, there's no blood anywhere except in the lounge.

Apart from this door here, we've got some smear contact.

So, there's some drips of blood on the floor just there.

Who they're from, I can't tell you till the DNA's come back.

And then as you come across onto the arm of the sofa there,

there's some runs of blood down the side.

So it could be, for example, a bloodstained hand.

But again, until I've got the DNA, I don't want to say who that is.

So I'm going to put two markers down.

Markers are used to highlight

where blood is located on the crime scene photos.

The arrows point to the direction of the blood spray.

On the sofa base on top of it,

we've got lots of drips, possibly some arterial rain as well.

There's further arterial going up the wall.

Ancl then we've got some more staining

down on the right-hand side.

That could be more arterial,

but because there's a lot less stains in that pattern,

I can't rule out it could also be cast off.

So "fluck" off from someone's bloodstained hand.

So again, I'd recommend sampling

in case it's your offender with a hand injury.

Really heavy contact staining on this central part of the sofa

that's actually soaked through the leather.

Ancl it's also cooling slightly. Ancl it's all over there.

There's the bed sheet as well.

So I think your deceased has been in contact

with that part of the sofa.

They were probably kneeling or leant onto it

when she's bleeding significantly.

And then she's gone down onto the floor.

In terms of on the floor,

there's very little projected blood from someone struggling.

There's not lots of spray or spatter around

that would suggest that she's been struggling, particularly.

So I think when she's down, that's it.

Then on the door, we've got the contact there,

which is roughly knee height.

Ancl then there's contact on the door handle.

So if you actually position yourself sort of leaving,

that's kind of where you would do that.

Ancl if you maybe graze your knee on the way out.

OK. So again, I'm sampling both of those

because that could be, for example,

suspect's clothing with victim's blood,

and that could be subject with a hand injury.

Over three days,

eight forensic experts have worked on the murder scene at the flat.

Their findings are immediately forwarded to the homicide team.

Our suspect is Satpreet Singh Gandhi.

He was arrested close to his home address.

He's described as being covered in blood.

He's got blood on the knee of his jeans.

He's got a cut to his hand.

He's got blood on his trainers.

He's got blood to the rear of his jeans and his left pocket

into the rear of his left shirt.

And he was taken to Elland Road Police Station.

So, we've submitted a number of items to the lab for analysis.

The suspect's clothing. Some clothing from the victim.

'The clothing is going to be submitted to the lab

'to see whether there is any presence

'of the victim's blood on that clothing.

Ancl the scientists at the lab will perhaps be able

to provide some interpretation around the blood staining,

which will assist in determining the sequence of events

and also prove that the suspect had contact

with the victim when she was bleeding.

At the suspect's flat,

a second forensic team is assessing a potential murder weapon.

So, we've got a bloodstained knife on the coffee table.

No discernible pattern in it. It's kind of smeared down the blade.

Again, I haven't got measurements yet for you,

but it looks about three centimetres in width,

perhaps 20 in length.

But the knife isn't all they find.

Oh, yes. That's the other thing. Yeah.

There's handwritten notes.

Now, they're under one of the... Well, actually, under both knives.

So when we recover them, we'll photograph those

and then recover that as a collected item.

We'll box that up.

Ah, single-sided.

Police inquiries have resulted in revelations

about the relationship between the suspect and the victim, Harleen.

The victim doesn't have any family in England.

So she's got a brother, her mother and father in India.

So they've been notified over the telephone.

Looking at our victim and suspect,

inquiries identify that the suspect and our victim are husband and wife.

NARRATOR: Harleen Kaur has been brutally murdered.

Police are now building the case against the prime suspect,

her estranged husband.

THEY CONFER

Satpreet Singh was previously married

to Harleen's older sister, um, in India.

Um, she died of a heart attack in India, we're told.

He then went on to marry Harleen afterwards.

This was something that we looked into as a team,

as a line of inquiry,

to understand the nature of that relationship

and how that relationship had come to a conclusion.

The police need to tread carefully as they inquire

about the death of Harleen's older sister.

'We asked the local police to give us some information

'in relation to the nature of that, ancl we also asked the family.'

They provided us with a death certificate,

and it became apparent that the death was by natural causes.

'So there was no suggestion of criminality.

'No lines of inquiry for the investigation team to follow.

'For me, it's a tragedy.

'We've now got a family that have lost

'both of their female adult children.'

Satpreet Singh had one child with Harleen's older sister

and since had another child with Harleen.

Him and Harleen were raising both those children

prior to them separating and Harleen's death.

Both children were with their grandparents in India

when the murder happened.

They came to the UK for Harleen to study at university at Leeds.

'He came along with her as her husband.

'She did her studies, began working,

'and met a big group of friends at university and through work.

'Ancl I think that's part of what Satpreet Singh has struggled with

'and what's made him quite angry towards her in this case.

'They'd separated, they were living separately,

'so Harleen got the flat at Headingley.

'Satpreet Singh had the flat at Kirkstall

'where he was living on his own.'

Six months earlier, Harleen had rented the room

less than a mile away from her estranged husband's flat.

Police were contacted by a witness, and he lives in the shared house.

'And he reports an ongoing domestic at that address.'

On the night of the murder,

the lodger was the first to alert the police.

He said the victim was shouting for help and screaming and crying.

He's contacted the police, concerned,

and he's made his way around the properties to the front...

...where he's waited for police to arrive.

Those first responders are quickly followed by firearms officers

to the suspect's address.

Officers attended at the suspect's home address.

'He was actually in a shop at the other side of the road

'when the officers got there.'

Um, but from the CCTV at the shop,

we knew that he became aware of the officer's presence.

'He's gone outside.'

And the suspect approached the officers.

Almost straightaway,

he's made comments to the effect of, "|'ve killed my wife."

He was arrested on suspicion of Harleen's murder.

After the apparent confession on his arrest,

Satpreet Singh Gandhi was taken for immediate interview by detectives.

DETECTIVE: I have to remind you that you are under caution,

so you do not have to say anything,

but it may harm your defence if you fail to mention when questioned

something you later rely on in court.

Anything you do say may be given in evidence.

'The caution at the start of the interview says,

' "You do not have to say anything," so they don't have to speak at all.'

You can say nothing, some things, or talk to us.

If you decide not to say anything.,

could you say "no comment" or "no reply"?

But the next part of the caution is really important,

which is, "|t may harm your defence if you do not mention

"when questioned something you later rely on in court."

If you don't say anything today and this matter does go to court,

and then you give an explanation,

and the court thinks it would have been reasonable

to give that explanation now, then it could harm your defence,

and the court or jury could come to their own conclusions

as to why you didn't give that explanation

when interviewed by the police.

'Usually what we do as an investigation team

'when we're interviewing people is do an initial interview,

'ask for an initial account from the suspect.'

We might then ask for a further interview,

where we give a little bit more information,

a little bit more evidence, and then subsequently conduct

what we call a challenge phase interview

with the final evidence,

the information that challenges the suspect's account

that's been given.

So it's to make sure.

People may have it read one time or 300 times.

We have to make sure they understand the caution.

While Satpreet Singh Gandhi is being questioned about his wife's murder,

his bloodstained clothes are being forensically analysed.

DETECTIVE: When you were arrested last night,

you were brought into custody.

The clothing that you had on was covered in blood.

Whose blood is that?

No comment.

'Initially, the scientist is looking at the trainer

'through the microscope

'to determine whether they can see any blood staining on the trainer,

'and use a specialised light source

'to help visualise any small or fine stains.'

The examinations are carried out in a sterile environment.

'The scientists will lay the clothing out altogether

'as if it was on a person.'

So the polo shirt at the top,

the jeans and then the trainers towards the bottom

so that they can look at them all together

and the distribution of blood over all items of the clothing

to help with their interpretation.

'So he's pulling the pockets out

'to see whether there's any blood staining

'on the insides of the pockets.'

We can get a DNA result from the blood,

and then the scientist has to interpret that

and compare it to the profiles from the suspect and the victim.

So, there's been notes left

which were found in the address of our suspect

about how coming to the UK has affected the suspect's life,

how things started to go wrong,

how the victim was making friends

with, uh, males and females and new groups,

how his thoughts have deteriorated,

that she was partying.

He will say that he turned to drink,

and that she wasn't spending time with him.

DETECTIVE: Tell me about Harleen Kaur Gandhi.

No comment.

Tell me about the person she was.

What sort of a person was she?

No comment.

The suspect's family in India have come forward

with concerns about his mental health.

He's been sending them messages on WhatsApp.

'A further call comes in at 19:51 .'

And this is from a family friend of the suspect,

and the suspect's family who are in India

have contacted him on WhatsApp,

saying that the suspects raising concerns

that his wants to leave the world and has a had a fight with his wife.

The handwritten notes and the WhatsApp messages

now form a key part of the police evidence.

This is a typed document that was sent

on a family WhatsApp group prior to his arrest.

Family have sent it to friends in England who have given it to us.

It says, "My wife, Harleen Kaur showed me her real face.

"What a bitch she is.

"I have to go in UK. She started hiding things with me."

DETECTIVE: What's your relationship with Harleen been like?

No comment.

Has it been a loving relationship?

No comment.

Have you had fall-outs with her?

What is that?

He's seen that as her being secretive.

Ancl him, I think, losing that control

that he thought he had on her.

Were you obsessed with Harleen?

No comment.

It's just a young lady enjoying going out with different people.

But he he's seen that as almost like a slur on him

and that something he needs to take control of.

Did you hate her?

No comments.

'It was shocking at first to get a no comment.'

He was interviewed on three occasions.

Um, quite lengthy interviews, but he's not made any comment.

Tell me what happened.

just you know what happened in that address

cos you were present.

Tell me what happened.

No comment.

Nah, he's given us no explanation of to why this has happened.

Though the suspect seemed to admit his guilt on arrest,

he still hasn't been charged.

A conviction should mean a life sentence.

But how long the killer serves in prison

depends on whether the murder was premeditated.

Detectives are now exploring any evidence

that the suspect has intended to kill his wife.

DETECTIVE: What has been your reason for going there?

No comment.

'We want the maximum sentence for him.

'He has taken someone's life.'

If his team try and go down the route of saying something

to try and get a lesser sentence,

what we try and do is put all our evidence together

and show that this wasn't a one-off.

This was premeditated. This was planned.

Have you arrived there calm, ready to chat?

No comments.

Have you arrived there...

...worked up and ready to have an argument with her?

No comment.

While the suspect continues to say "no comment" in interviews,

a specialist team, known as PolSA, begin detailed searches

at both the crime scene and at the suspect's flat.

It's the only thing, it were in the bin in water.

Get the CSI to double check it.

One of the search team is exhibits officer DC Rachel Kennedy.

We are still missing one knife.

So, that packet, is it the medium one we're missing?

Yeah. Yeah.

It's not unusual for searches like this

to have hundreds of exhibits and take days to complete.

I now you said laptops were on the list.

It's an Apple MacBook. Right.

He's got a roll of little ones. I say, "Roll with it."

That should be... Fantastic. Thank you ever so much.

One of the most important things when you're dealing with exhibits

is being exact.

So what you've got,

and particularly where it's been seized from.

If we find passport or ID cards from India,

particularly of the suspect and the victim,

they might help us.

Um, and the other one was, if you do happen to find any paperwork

that looks like he's trying to get things in order,

anything to do with life insurance or anything like that, please.

This accurate recording of items found during the search

could prove crucial at trial.

Say, for example, you had some CCTV

of an offender running behind a car

and behind that car, you found a knife,

then, you know, it's really important

to say where the exhibit was found.

'Ancl it may link in with other evidence,

'other corroborative evidence

'that is provided to the investigation.'

So, yeah. So, that was on the top shelf.

There was these... What do you think that is? Is that a visa?

Right, OK. So that needs to come separately.

I can get... If it's bloodstained.

just anything with any potential blood staining on it, then.

DETECTIVE: The knife was located at the address with blood on the blade.

Can you tell me about that knife?

No comment.

How did that knife get into your flat?

No comment.

Will you be forensically linked to that knife

by your fingerprints or DNA?

No comment.

Will the blood on that knife...

...be that of Harleen's.

No comments.

To pursue a charge of murder,

the police must establish the killing was premeditated.

They're reviewing the suspect's WhatsApp messages

to gain an insight into his state of mind.

Well, it's almost like a diary entry of, um, a summary of what he's...

what he perceives him and Harleen have gone through.

Um, it's just full of emotion

and kind of jumps about from topic to topic.

Um, clearly written with some emotion

and some anger in parts of it as well.

It says, "She had gone in a world

"where she just didn't want to listen to me

"and do whatever she wanted."

Ancl again, that seems she was no longer obeying him.

Ancl I think that's a big motive for him doing what he's clone.

DETECTIVE: Did Harleen change?

Did her attitude change? Did her way...?

Did her feelings towards you change in that time?

No comment.

He says, in July 2021,

"I hacked her mobile for the first time."

That'll be really important in the sentencing

that he's hacked her phone

and that kind of domestic element of control and coercion.

"I found that she was chatting with her male friend

"and the chats were not normal."

Ancl he sees these chats with her male friend

as being something inappropriate.

Has Harleen started seeing anybody else?

No comment.

Ancl this is all kind of building up a picture

of how he saw himself losing his grip on Harleen

and that she was moving on from him.

He says, "We started some conversation.

"She told me that she's going to live with her friends now,

"and she started to pack her bags."

Do you currently live together?

No comment.

"I was drunk and just wanted to stop her from going.

"I pushed her and "hold-ed" her tightly, but only to stop her.

"Never had any intention of beating her.

"I just wanted to stop her."

Has your attitude towards Harleen changed?

No comment.

If so, why has that changed?

No comment.

What happened to have changed any feelings

that you had for each other?

'We've confirmed there's been some element

'of previous domestic physical violence between them,

'in the defendant's own words,

'that there's been some physical altercation.

But obviously, that is the start of physical domestic violence

against Harleen that's escalated and escalated

to what we've ended in.

I've got his red rucksack.

Here is his rucksack. Oh, is it?

Pinky-red will do. Right. 0|

I'll give Kate a ring and tell her what we got.

The suspect's flat search has revealed more key evidence.

It's like a deep pink.

Very dark blue rucksack just on the sofa.

I'm guessing that will be the one that you're after.

AFM Kate Whitehead relays this back to the investigation team.

'I've recovered the rucksack and a metal water bottle,

'which was bloodstained.

'Within the rucksack, bloodstained clothing, a T-shirt.

'|'m not sure that it's a T-shirt that he's had on,

'but he may have put the knife into the rucksack,

'and that may be how that T-shirt has got bloodstained.'

A 20cm blade.

She's given the cause of death,

as we suspected, as stab wound to the chest.

She describes it as being a single stab wound,

but an irregular wound that appears to show

some sort of sawing action once the knife was in.

DETECTIVE: You inflicted that stab wound.

No comment.

Thought you'd say that.

There's just this one stab wound.

However, there's numerous insertions inside,

which means the knife has been pulled in and out

a number of times.

Tell me how that has come to be.

No comment.

'She describes multiple stab tracks in the lung.

One that's penetrated the back of the left chest cavity.

Almost reaching the surface of the skin on her back.

They're saying that a knife of at least 15cm

would have to have caused that injury.

Have you taken a knife with you?

No comment.

Or inflicted that injury to her?

No comment.

The only other injuries that the deceased had

were defensive sharp force incise wounds

to her left fingers and one to her right thumb.

What happened from the argument

to lead to Harleen suffering that major injury

that resulted in her death?

No comments.

Went back after the PM results.

Talk to him about the incident.

I think he got quite emotional on that one.

As if he almost wanted to talk.

just carried on. "No comment".

Has she tried to grab the knife from yourself?

No comment.

She's had it pulled out of her chest,

and this is how there's numerous insertions into her.

You've tried to push it back in?

While the interviews continue, the first evidence emerges

to confirm the killing was premeditated.

Witness accounts suggest Gandhi had been stalking Harleen.

A member of the public raised concerns

about a male described as...

a male wearing a turban, smartly dressed,

hanging around by the bins and the bushes at Victoria Road.

Ancl is described to have a red rucksack.

I believe this to be our suspect.

I believe that he's potentially been watching our victim's movements

over the past week.

NARRATOR: In the investigation into the murder of Harleen Kaur,

detectives are working to establish that her killing was premeditated.

It's now become their key focus.

We have three what we'll class as key witnesses who have come forward.

'So our offence took place on Monday the fifth,

'so Thursday the first before,

'a witness who lives nearby

'to the victim's address contacted us saying that.

'Ancl had been surprised to see a male

'stood in the bottom of her garden

'looking from the bushes across the road.

'He would have had sight on the victim's home address.'

She thought it was quite strange,

and she eventually contacted the police

to say there's a suspicious male.

'But within a few minutes after, he walked away.

Ancl she describes him as an Asian male

with a black turban and 30 to 40 years of age.

We then go on to Friday the second,

where yet again, we have a witness who lives nearby,

stating that she saw in the mid-afternoon

a male stood outside her garden wandering.

She described this male as being of Asian descent, having a turban,

but also of note, having a red rucksack on his back.

Then on the Saturday, we've had another witness saying

that she'd come home early evening,

and she's been surprised to see a male

at the bottom of her garden by her bins,

crouching down and looking through the bushes.

Detectives now search through hundreds of hours of CCTV

to verify the witnesses' claims.

Of course, one of our theories at the moment is that

Satpreet Singh might have been stalking her for some time

before he committed the offence.

More new evidence comes to light

when the knife recovered from the suspect's home

leads detectives to a local supermarket.

Once he was arrested and we got into his flat,

within the flat was an open packet of knives

that was packaged with Ascla logo on it.

The murder weapon was a part of that set,

and as a result of the enquiries,

we've gone to the nearest supermarket

and we've established that that set was bought from there.

Ancl we've got CCTV footage of him going into the Ascla store,

even speaking to a member of staff and the staff directing him

to where the knives were located on the aisles.

We know that on that clay he purchased these knives,

he also bought some crisps, and he also bought some vodka.

Satpreet Singh Gandhi purchased those knives on the 28th of August,

which is some eight clays before the murder.

'It weren't just a fit of rage.'

He'd been planning this for quite some time.

Now the digital forensics team track the suspect's mobile

and his movements via the phone network.

What we were able to determine is that Satpreet Singh's mobile phone

was pinging on a mast near to Harleen's flat

on the first, second, third and fourth of September,

which we think is relevant

based on what's happened on the fifth of September.

The digital forensics strengthened the case

that Harleen's murder was premeditated.

It provides us with lines of investigation.

It provides us with a story of events, of movements,

both the victim's movements as well as the suspect's movements.

So what we can say is that the clays prior to the fifth,

we have got Satpreet Singh Gandhi in the area around Harleen's flat.

Ancl we would say watching Harleen's flat.

Detectives now begin to create an accurate timeline of each day

leading up to the murder.

It's always very important to come back and visit the scene.

Familiarise yourself with the scene

because it's a massive part of the investigation.

From phone data on the third,

we've identified that Satpreet Singh's phone

is hitting a mast near to Harleen's flat

from 9pm onwards on 3 September.

So what we've clone is we've reviewed CCTV footage.

Our CCTV is mainly from this building,

and we catch them on our footage.

And at 21 :37 hours, we have captured Satpreet Singh

stood directly outside Harleen's flat.

He goes down the steps and comes back out.

My view is that he's probably known that there's nobody there,

and he walks back towards these bins,

and for a couple of seconds, he stops.

So, what we've got is Satpreet Singh here,

entering the threshold towards Harleen's property.

Ancl if you look what's in his right hand,

you'll see a shining object.

With the key CCTV from two days before the killing,

the team now concentrates its efforts

to events on the day of the murder.

So, here he is leaving this flat.

Ancl what he does is he does come across the road

and makes his way into the Premier store.

Ancl what he'll do is he'll purchase some Skittles,

and you will clearly see him

in possession of the rucksack on his back.

We believe in the bag,

he's carrying the weapons that he's used in the attack.

Ancl then he'll make his way back onto Greenhow Road.

Only this time, he has booked a taxi to take him back up

to the location where Harleen lives.

So, this footage,

this shows Satpreet Singh turning up in this taxi.

Ancl this is at 15:41 hours.

Ancl he's got with him his rucksack in his hand.

But the fact that he's in the area once again,

hours before the incident occurs...

...it paints a picture of what...

...what's about to unfold, really.

NARRATOR: Harleen Kaur has been killed by her estranged husband.

Police must prove it was premeditated

in order to charge him with murder

and try to secure a life sentence.

More CCTV of Gandhi lying in wait near the victim's home has emerged.

He's just walking around, a lot of pacing.

So there's a lot of coming to the side,

looking over to see if anyone's there,

coming back out of eyeline from the flat,

coming back to this side.

We think that's his main focus, is the address.

If anybody's there, if she's there.

He's always got a view from whichever position he's at.

The evidence is then put to the accused.

Is that you, Satpreet?

No comment.

What are you doing at 15:44 on the fifth?

No comment.

But we then came next door to the cafe.

And what we found there was

that he was hanging a lot in this decking area

and around this driveway area.

Are you watching that address?

No comment.

It gave him a prime location for viewing, and once again,

anybody who left that flat came out

would not see him sat up in the decking area.

But he had a perfect view of that address.

On the night of the murder, this is where he's sat just prior

to picking up his bag and walking across.

You've now crossed over. Where are you going?

No comment.

We've seen him come down these steps.

He crosses this road.

He's got his red rucksack with him.

He's coming across here.

We see him on the footage go down the steps, out of sight,

where we lose him on CCTV.

You go down them steps,

go into the rest, tell me what happens.

He's not made any comment. Just...

He has cried on a few aspects of the questioning.

We've also spoke about a call made to the victim's family in India,

where his children are staying.

You don't have any contact with your children, do you?

Unless it's phoned through a specific person.

That'd be correct?

No comments.

How does that make you feel?

Not having contact with your children?

When we spoke about that issue,

he's become very upset and asked for a break to compose himself,

and it's taken him ten minutes to compose himself

before we carried on the interview.

SATPREET MUMBLES Yeah. Right.

The time is 16:09,

and we're going to pause the interview

for you to have a chat with your solicitor.

Ancl then when we introduced witness statements

a couple of clays prior, that took him by surprise.

He looked at his solicitor a couple of times,

he looked a bit, like, shocked, but I asked him about the rucksack.

I said we looked two or three clays before,

we were always going to see you walking with the rucksack.

It took him quite a while before he answered "no comment" on that one.

You've still got your distinctive rucksack.

What's in the rucksack at that time?

No comment.

Do you always carry a rucksack?

No comment.

So, what do you carry in your rucksack?

No comment.

Yeah, it definitely feels like he's...

He's thought he's going to do this for some time.

He's gone, and he's clone various recces, hasn't he?

The witness statements and CCTV corroborate the police theory

that Satpreet Singh Gandhi had been stalking Harleen

for days before the murder.

He's gone and clone what he's clone to her

and then potentially has intended to harm himself,

but for whatever reason hasn't clone so.

While Gandhi continues to be questioned,

the forensic analysis of the clothes he was arrested in

returned key findings in blood and DNA.

The scientists examined the T-shirt

that we'd submitted from the victim's address.

In the scientists' opinion,

this damage can be considered to correspond

to the injuries sustained to the victim's left breast,

ie, she was wearing this T-shirt when she was stabbed.

Ancl the forensic analysis of the suspect's clothing,

and the scientist's report for the blue short-sleeved shirt

that he was wearing when he arrived in custody -

on the centre front,

there are numerous heavy spots of blood, which, in her opinion,

relate to arterial spray.

Ancl also of note,

there were some very fine spots of blood on the chest area,

which, in her opinion, appeared to have been exhaled onto the shirt.

The DNA profile obtained from the shirt

matches that of the victim.

In the scientist's opinion,

the overall distribution of blood staining

present on the trainers

is in keeping with the victim's body

having come into contact with the right trainer

whilst she was injured and bleeding.

Also, after she had gone down to the ground,

the presence of spots of blood on the mid soles

could be explained by the suspect having straddled her body

and/or moved her around whilst she was exhaling blood.

Taken together, in the scientist's opinion,

the overall distribution of blood staining present

on the suspect's clothing and footwear, which places him

in a prolonged and dynamic interaction with the victim

after she had sustained her injuries.

The evidence is showing that he was present

with the victim while she was injured and bleeding.

If you've got somebody's arterial spray

or somebody's exhaled blood on your shoes and clothing,

then you were with them at the time

that they were still alive and bleeding

because their heart is still pumping,

they're still breathing.

So that is incriminating.

At any time, did you try to give first aid to her?

No comment.

With evidence against him overwhelming,

Satpreet Singh Gandhi finally admits to murdering his wife,

and detectives are hopeful a life sentence

could be handed down by the court.

During the charging process,

I did notice that his legs were shaking and quivering

and his body buckled of times,

which displays the gravity of what he's being charged with.

So I'd have to position myself closer to him,

because at one point, I thought he was going to faint.

But he managed to compose himself

and rest himself against the wall in the custody area.

Sometimes, it's the gravity

of having that charge read out to you

and knowing that you've been charged with murder.

That's overwhelmed him.

It's been two months since the murder of Harleen Kaur.

With an admission of guilt, there'll be no full trial.

But the court must now decide Gandhi's sentence.

Without proof of an intention to kill,

it could be substantially reduced.

We think the intent is that

he's there, he's planned this, he's gone,

and he's not found the right occasion on the nights before.

Ancl then we think on the night of the offence,

she's present, and he's gone in, and he's committed the offence.

NARRATOR: Satpreet Singh Gandhi has confessed to the brutal killing

of his estranged wife, Harleen Kaur.

They had two children together.

They are now being raised by their grandparents.

The family live in India,

but they have provided an impact statement

explaining how Harleen's murder has affected them.

So, I've got the victim personal statement

from the brother of Harleen who was murdered.

These were only read in court after conviction

to assist the judge with sentencing.

"Harleen had laughter that would bounce off the walls

"and resonate with everyone.

"She brought light into the darkest of rooms

"with just a single cheeky smile.

"And her eyes always had the most beautiful twinkle to them.

"Now everything just seems darkened and dull without her.

"Her parents have to take care and grow both their daughters' children

"in their old age.

"Every night, I and the children and my parents

"have nightmares of what you did, of how you hurt her.

"How scared she must have felt in those final moments.

"How she probably died feeling like she was alone or unloved.

"You have traumatised so many of us.

"Her children are not able to sleep, study, have gone into depression,

"and always say, 'I want to see my mother and talk to her.

" 'How can clad do this to our mother?

" 'Doesn't he love her and us?'

"We know you are guilty for murder.

"This is something we knew the whole time.

"By pleading guilty so close to your trial,

"you are only looking to reduce your sentence.

"Your hand has clearly been forced

"through the painstaking investigation

"and collection of evidence

"conducted by dedicated police officers.

"Marriage is about love and affection,

"which Harleen gave you, and you were not worthy of it.

"And she wanted a divorce.

"First time she thought for herself. Ancl you killed her.

"She's not a property.

"|f you don't want, don't like, or don't listen, you destroy.

"She was a human being and not a monster like you.

"You will never be forgiven.

"What you have clone to her will never be forgotten."

It's very impactive.

A victim impact statement gives the judge who's sentencing

the ability to get into the mind of the victim's family,

and the impact that it's had on them,

not just at the time of the offence, but the ongoing impact.

It's tragic.

It's hard not to be moved when you when you read

the words from Harleen's brother on behalf of the family.

Ancl I think, as you know, as a husband and as a clad, um,

it's really difficult to hear.

Ancl you kind of, I think, put yourself in that person's shoes

and think, "What if it were me having to write that?"

So it is harrowing.

But again, it's the reason why, I think,

the team are all so driven to do the jobs

and get the right results for the victims and the families.

How are the family feeling about today?

I think they're looking forward to getting some closure,

getting to find out exactly what he's going to get.

Custodial time.

Today, the judge will decide how long Satpreet Singh Gandhi

will spend in prison.

What's your thoughts on how it will go?

Obviously, prosecution will get a chance to put their points across.

Ancl I think we're looking at a starting point

for bringing a knife to the scene is going to be 25 years.

I think there's a lot of aggravating features

with the domestic violence and the control, the coercion,

and sort of the stalking, the pre-planning before.

But let's see what the judge thinks.

All the investigators can do now is wait.

It's important that we've gathered further evidence.

Things like bringing the weapon to the scene.

You know, we recovered the knife.

All those hours of looking through the CCTV to catch him stalking her.

All those little things make a really significant difference

to the sentence and to the starting point of the sentence.

But the important thing, we're telling the story of Harleen

and how she lived for the last few months of her life.

The judge gives his decision.

Satpreet Singh Gandhi is sentenced to 23 years and four months

for the murder of Harleen Kaur.

So the judge sort of summed up the case quite well.

He set the starting point at 25 years.

The aggravating features put it up.

Ancl then he got a sixth-off credit for a guilty plea.

So it went back down and ended up at 23 years and four months.

Um, which I think is a fair sentence.

He's not coming out for a long time.

The family are over in India.

They couldn't make it for the trials,

but they were on a video link.

So basically, they got to see the court

and hear what was being said.

As soon as it finished in the courtroom,

I rang the family and spoke to them

to explain to them exactly what had gone on.

Whatever sentence they get,

it doesn't reflect the value of the life that's lost.

We always find that with these cases that whatever the number of years,

it doesn't reflect the value of that person's life.

It's really hard because you think about the victim and her family.

It's really hard to say, "Oh, it's a good result for our team,"

because somebody dying and being murdered

is never a good result.

Harleen had wanted freedom from her stifling marriage,

but her killer had wanted to control her.

The police take domestic abuse incredibly seriously.

It has a huge impact on victims,

on victims' families and on the community as a whole.

This is an incredibly serious case.

A woman sadly lost her life

as a result of domestic abuse and domestic violence.

Myself and my team have worked as hard as we possibly can

to get the best result and best outcome

for the victim, her family and her children.

There's been an attempted murder at a convenience store in Yorkshire.

GUNSHOT, SIRENS WAIL

Yes, I have got a CSI available.

You can actually see the shot on that.

Shotguns are very lethal.

The offence is attempt murder.

He's been very fortunate to survive this.

We're now tracking a gentleman on a mountain bike.

So we need to make sure we brief the search teams as well.

One thing that we get there is gunshot residue.

You already had a shotgun in your possession.

He's actually been using firearms.

The evidence that we collect can be key to an investigation.

When you look at the evidence,

there is sufficient for us to put it before a jury to decide

whether the defendant is guilty.
