Women who kill savaging their own.

Why on Earth would any mother raise
a child and then kill it and burn it?

Making a game of murder.

Shockingly, brutal acts.

I robbed them and I killed
them as cold as ice.

What drives them to these extremes

and who is most evil?

A scale exists to measure the darkest
corners of human behavior.

Acts of evil.

It weighs the criminal mind and the crime.

From impulsive murderers to serial

killers, science now has a tool
to determine who are the most evil.

93% of murders are committed by men.

What motivates the few women driven
to kill Mary Beth Tenning's?

Nine children mysteriously die one by one.

Cathy Wood and Gwen Graham,
nurses aides in Michigan,

play a vicious game
that takes the lives of five patients.

Theresa Noor ruthlessly tortures her
six children and kills two daughters.

Mothers and caregivers are expected
to nurture,

yet they are capable
of appalling evil acts.

Tammy Lynn Tenning was the 9th child
to die in the Tenning family.

But not all evil acts are equal.

How these women kill and why is different?

What compels these atrocities?

To determine their degrees of evil,
one must compare their crimes.

Now there is a scale with 22 levels that
measures the different degrees of evil.

It weighs the killer's motive,
method, and malice.

The more calculated and brutal the crime,

the higher the criminal
is placed on the scale.

My scale helps me navigate the rather
turbid waters of violent crime.

Creator of this scale, Dr.

Michael Stone, forensic psychiatrist
at Columbia University.

Dr.
Stone asks probing questions.

What are the personality characteristics?

What are the background
history of drug abuse?

Parental neglect, parental brutality?

Is it possible to be born evil?

Most women who kill end up
on the lower levels of Dr.

Stone's scale of evil because they
are one time impulsive killers.

Women like Jean Harris,

the head mistress at a private girls
school,

Harris shot and killed her lover when
she discovered he was having an affair.

Dr.

Stone places Harris at the low end of his
scale level two crimes of passion.

As he continues to examine
the cases of women who kill, Dr.

Stone notices another pattern.

You find that the overwhelming majority

have killed somebody
in their intimate circle.

They might kill a spouse or sexual

partner, they might kill a parent,
or they might kill a child.

As was the case with Mary Beth Tinning.

Skincare New York
Mary Beth Tinning and her husband, Joe,

have two healthy children,
Barbara, four, and Joseph, one.

Mary Beth is pregnant
with her third child.

Shortly before the baby is born,
Mary Beth's father dies.

Three months later,
her newborn baby dies of meningitis.

Before the funeral, she begins
what will become a ritual.

She carefully washes the baby's clothes

and packs them away,
along with the baby's toys and furniture.

At the funeral, she is overwhelmed
by not only grief, but sympathy.

Friends and neighbors flock to her
side and attend to her every need.

Two weeks later, Mary Beth brings her
son Joseph to the emergency room.

He is pronounced dead.

Cause unknown.

Just one month later,

Mary Beth brings her one surviving child,
Barbara, to the hospital.

They urge her to leave the child there.

But she takes her home.

Barbara dies the following day.

Her third child to die
in the span of two months.

Once again, before the funeral,

she performs her ritual.

To understand Mary Beth Kinney's response

to the attention she received
when her children died.

One must look to her childhood.

As a child.

Mary Beth Roe acts out at school
and has few friends at home.

She feels like the daughter
her parents never wanted.

Her father is cold and inattentive.

He locks her in a closet.

When she cries,

it is his attention that will always
remain just outside her grasp.

As a teenager, she is
viewed as an outsider.

Her one school activity President
of the Future Homemakers of America.

Then Mary Beth's father falls ill.

Even on his deathbed, he shows little
connection to his only daughter.

Mary Beth Tuning's father died without

ever showing his daughter
the affection she craved.

The subsequent attention she got from her

baby's death may have been
a psychological trigger.

Mary Beth's three children have died 93.

A fourth baby, Timothy, dies.

Over the next few years, three more of
Mary Beth's children die at the hospital.

Three of the deaths are
attributed to SIDS.

And four deaths are
listed as cause unknown.

She repeats the same ritual.

Friends and neighbors tried to console

the woman who has suffered
so many tragic losses.

They whisper of a rare genetic disorder

that might be claiming
the lives of her children.

Funeral of any child is a difficult
thing for a funeral director.

And this family just seemed to have so

much bad luck that our hearts here
went out to them.

But in 1981, the whispers of a genetic
disorder suddenly grow quiet.

A boy she is adopting dies now.

Suspicion rather than sympathy follows
Mary Beth Tenning

five another baby, Tammy Lynn dies

and Mary Beth Tenning is arrested.

Tammy Lynn Tenning was the 9th child

to die in the Tening family
in the past 14 years.

When police question her,
she tearfully breaks down,

telling investigators she never
felt she was anything in life.

She confesses to smothering
three of her children.

But denies harming the others.

Why would Mary Beth Tinning
harm her own children?

She showed a rare pattern of behavior
the doctors call Munchausen by.

Proxy.
