And three new victims
have just met their fate.

00:00:25,317 --> 00:00:27,736
A big bull hippo,

Anyone could be a suspect.

Killers can be victims
15
00:01:02,229 --> 00:01:04,148

This young male hippo
is eight years old.

A member of the 300-strong pod
of hippos living at Big Bend.
21
00:01:51,028 --> 00:01:53,197
He’s lived here all his life

and has finally
reached sexual maturity.

This morning,
his body was discovered
floating in the river.
26
00:02:19,848 --> 00:02:22,726
A killer has paid
the pod a visit,

leaving its victim
dead in the water.

Three suspects
were seen in the area.

A group of crocodiles
that hunts along
this stretch of river.

Let’s analyze the suspects.
40
00:03:29,251 --> 00:03:31,962
Crocodiles share the river
with the hippos.
41
00:03:37,175 --> 00:03:41,471
Proximity to the victim
makes these guys
a prime suspect.
42
00:03:44,057 --> 00:03:46,101
And they’ve got priors.
43
00:03:46,143 --> 00:03:49,396
Crocodiles are frequently
seen eating hippos here.
44
00:03:53,984 --> 00:03:58,864
They have one of
the strongest bite forces
of any animal on earth.
45
00:04:06,246 --> 00:04:09,416
Plenty powerful enough
to take on a hippo.

(HISSING)
47
00:04:13,587 --> 00:04:16,048
They use their
needle-sharp teeth
48
00:04:16,089 --> 00:04:20,051
to rip chunks off the carcass,
swallowing them whole.
49
00:04:26,558 --> 00:04:30,645
And their powerful tails
and infamous death roll
50
00:04:30,687 --> 00:04:34,316
give them the strength
to break through
even the toughest skin.
51
00:04:40,238 --> 00:04:43,074
A hippo would provide
an incredible feast
52
00:04:43,116 --> 00:04:45,368
for a group
of hungry crocodiles,

when taking on a hippo.

A fully grown adult could bite
a nine-foot crocodile in half.
57
00:05:06,681 --> 00:05:11,644
So are the crocodiles
the hippo’s killers
or just scavengers?

He has fought his way
to the top to reign

incisors for stabbing
and canines for slashing.

competition between
bull male hippos
is at its peak.

In these fights for dominance,
the stakes are high
69
00:06:27,178 --> 00:06:30,765
as the winner
gains mating rights
to the whole hippo pod.
70
00:06:34,185 --> 00:06:38,439
For a young male, a fight
with a beach-master is risky.
71
00:06:40,734 --> 00:06:43,153
But the potential reward
is huge.

it’s all about teamwork.

do they have the skill
and muscle power

But who is the killer?
102
00:10:20,870 --> 00:10:22,413
Let’s review the evidence.
103
00:10:25,041 --> 00:10:27,377
The carcass was
discovered in the river,
104
00:10:27,418 --> 00:10:30,379
so the killing
almost certainly
took place there.
105
00:10:32,966 --> 00:10:36,511
The most obvious suspects
are the crocodiles,
which hunt in water.
106
00:10:38,346 --> 00:10:41,099
But they would have ripped
the carcass to shreds,
107
00:10:41,141 --> 00:10:43,560
tearing off limbs
with their signature
death roll.
108
00:10:46,229 --> 00:10:47,731
So it wasn’t the crocs.
109
00:10:50,733 --> 00:10:53,027
Lions rarely hunt in water,
110
00:10:54,821 --> 00:10:56,906
but if they had
killed the hippo,
111
00:10:56,948 --> 00:11:00,493
they’d also have
taken huge chunks
out of the carcass.
112
00:11:01,870 --> 00:11:04,998
But the skin is unbroken.
113
00:11:05,039 --> 00:11:09,043
And they probably would
have dragged the carcass
onto dry land to feed.
114
00:11:11,796 --> 00:11:13,965
So it wasn’t
the lions, either.
115
00:11:16,217 --> 00:11:21,305
Based on the wounds
on the hippo’s back,
a fight definitely took place.
116
00:11:21,347 --> 00:11:23,724
But many of
these scars are old,
117
00:11:23,766 --> 00:11:26,644
suggesting this
was an ongoing battle.
118
00:11:29,606 --> 00:11:31,399
That leaves one suspect...
119
00:11:32,650 --> 00:11:33,901
The beach-master.

It’s the young hippo
and the beach-master.
125

Coming into sexual maturity,
126
00:12:17,612 --> 00:12:19,614
the bachelor male has decided
127
00:12:19,656 --> 00:12:22,075
it’s time to take on
the dominant bull.
128
00:12:25,536 --> 00:12:27,705
The two seem equally matched.
129
00:12:33,836 --> 00:12:36,839
Slashing at each other
with their huge canines,
130
00:12:36,881 --> 00:12:39,008
it becomes a bloody battle.

Pushed back into the water,
132
00:12:57,944 --> 00:13:00,280
the young male
starts to struggle
133
00:13:00,321 --> 00:13:04,617
against the brute force
and experience
of the dominant beach-master.
134
00:13:24,971 --> 00:13:28,016
Exhausted from the battle,
he tries to escape.
135
00:13:36,441 --> 00:13:39,819
The beach-master
decides to make it
a fight to the death,
136

drags him underwater
and holds him down.

becomes still
once more.

Overnight, the drowned carcass
floats back up to the surface.
139
00:14:02,467 --> 00:14:06,513
The dominant bull
drowned the young male.
140
00:14:12,060 --> 00:14:15,063
Conflict like this is common
at this time of year.

face many challengers,

00:14:36,667 --> 00:14:39,170
so this killer
could strike again.
144
00:14:44,550 --> 00:14:49,555
The culprit
in this hippo carcass case
was the beach-master.
145
00:15:10,868 --> 00:15:14,413
Conflict within a species is
common in the natural world.
146
00:15:20,711 --> 00:15:22,504

Battles are short, but savage.
149
00:15:36,227 --> 00:15:38,521
One false move
could mean death
150
00:15:38,563 --> 00:15:41,191
as their horns are
the perfect murder weapon,
151
00:15:42,900 --> 00:15:45,444
piercing skin and flesh
like a dagger.
152
00:16:04,672 --> 00:16:10,678
This impala was killed
by a single stab wound from
his opponent’s sharp horns.

carcasses are discovered
where the cause of death
is much harder to uncover.

it won’t be long

leave the pride

for 80 million years.
175
00:18:27,648 --> 00:18:30,568
They have no qualms
in fighting a lion for food.
176
00:18:35,448 --> 00:18:38,326
Hippos are often
on a lion’s menu.
177
00:18:39,619 --> 00:18:40,829
(GRUNTS)
178
00:18:40,870 --> 00:18:43,915
But sometimes,
even they fight back.
179
00:18:53,507 --> 00:18:56,969
But in the last 24 hours
before the carcass
was discovered,
180
00:18:58,679 --> 00:19:01,307
just three suspects
were seen in the vicinity.
181
00:19:05,936 --> 00:19:06,979
(GRUNTING)
182
00:19:07,021 --> 00:19:08,856
A boisterous herd of buffalo.
183
00:19:10,816 --> 00:19:12,568
A prickly porcupine.
184
00:19:15,488 --> 00:19:19,242
And the Maneless Three,
a gang from a rival pride.
185
00:19:21,994 --> 00:19:24,622
But which of these
potential killers
186
00:19:24,664 --> 00:19:26,457
took the life
of the young lion?
187
00:19:28,417 --> 00:19:30,711
Let’s analyze the suspects.
188
00:19:45,768 --> 00:19:50,356
The buffalo
and the lions of Luangwa
are constantly at war.
189
00:19:52,525 --> 00:19:54,485
Lions love to hunt them,
190
00:19:57,279 --> 00:20:00,240
but the buffalo
are far from defenseless.
191
00:20:05,121 --> 00:20:10,043
The buffalos’ sharp horns
can puncture skin
and cut through muscle.
192
00:20:12,128 --> 00:20:14,839
A bone shield on their heads,
193
00:20:14,880 --> 00:20:16,632
known as a boss,
194
00:20:16,674 --> 00:20:20,344
is like a sledgehammer that
can deliver a lethal blow.
195
00:20:25,099 --> 00:20:28,603
And one kick
could crush a lion’s skull.
196
00:20:31,689 --> 00:20:34,525
Under attack
from a predatory lion,
197
00:20:34,567 --> 00:20:37,820
did these powerful herbivores
turn killer?
198
00:20:46,579 --> 00:20:49,582
This is an African porcupine.
199
00:20:52,501 --> 00:20:56,171
The stumpy rodent hardly seems
much of a match for a lion
200
00:20:58,215 --> 00:21:00,968
but he has
a quiver full of arrows.
201
00:21:03,888 --> 00:21:06,432
Thousands of
needle-sharp quills.
202
00:21:10,978 --> 00:21:13,564
These modified hairs lie flat
203
00:21:13,606 --> 00:21:15,525
until the porcupine
is threatened.
204
00:21:19,320 --> 00:21:22,573
Each quill is attached
to a muscle
205
00:21:22,615 --> 00:21:26,077
which is sent a signal
from the brain to contract
206
00:21:26,118 --> 00:21:29,538
when the porcupine senses
an imminent attack.
207
00:21:33,417 --> 00:21:36,921
But they deliver more than
just a prickle to the nose.
208
00:21:39,548 --> 00:21:41,800
It seems hard to believe,
209
00:21:41,842 --> 00:21:46,388
but these quills can get
so deeply embedded
under the skin,
210
00:21:46,430 --> 00:21:49,391
they’re almost
impossible to remove,
211
00:21:49,433 --> 00:21:54,438
causing internal damage,
but leaving no visible trace.
212
00:21:58,526 --> 00:22:02,822
Most adult lions
are too sensible to go
for this prickly meal.
213
00:22:06,075 --> 00:22:09,829
But did curiosity
kill our yearling cat?
214
00:22:28,264 --> 00:22:33,227
Male lions can be
the biggest threat
to their own kind.
215
00:22:33,269 --> 00:22:35,772
When they attempt
a pride takeover,
216
00:22:35,813 --> 00:22:37,648
the battle can be violent.
217
00:22:41,652 --> 00:22:45,030
They will kill any offspring
that aren’t theirs
218
00:22:45,072 --> 00:22:48,200
to ensure the females
come back into oestrus.
219
00:22:58,377 --> 00:23:02,131
This infanticide always
targets young cubs.
220
00:23:06,719 --> 00:23:09,222
But yearlings can
be victims, too.
221
00:23:15,019 --> 00:23:19,232
And for a teenage lion,
there are added risks.
222
00:23:22,443 --> 00:23:26,197
The pride is focused
on the new cubs
223
00:23:26,238 --> 00:23:29,283
and a curious,
over-confident yearling
224
00:23:29,325 --> 00:23:31,327
could get himself
into trouble.
225
00:23:35,372 --> 00:23:38,041
Did the victim wander off
and stray into
226
00:23:38,083 --> 00:23:41,003
the neighboring territory
of the Maneless Three?
227
00:23:46,175 --> 00:23:50,221
An accidental encounter
with the fiery threesome
228
00:23:50,262 --> 00:23:54,516
would result
in almost certain death
for any young lion.
229
00:24:00,189 --> 00:24:04,360
We have the motives
and killing strategies
for each of our suspects.
230
00:24:06,570 --> 00:24:08,572
But who is the culprit?
231
00:24:12,868 --> 00:24:14,661
Let’s review the evidence.
232
00:24:18,082 --> 00:24:22,169
Death by porcupine spine
is a slow process,
233
00:24:22,211 --> 00:24:25,172
taking days or even weeks.
234
00:24:25,214 --> 00:24:27,883
Our victim died
in just a few hours.
235
00:24:30,094 --> 00:24:34,265
There was also no sign
of any impaled quills
on the body.
236
00:24:35,432 --> 00:24:37,851
So it wasn’t the porcupine.
237
00:24:40,479 --> 00:24:42,898
There are also
no bite marks
on the body
238
00:24:42,940 --> 00:24:46,444
so it’s highly unlikely
to have been another lion.
239
00:24:48,654 --> 00:24:51,323
Whatever killed
the yearling
left no mark.
240
00:24:58,247 --> 00:25:00,332
So who was the killer?
241
00:25:02,418 --> 00:25:06,589
If you thought a buffalo
was to blame, you’d be right.
242
00:25:08,757 --> 00:25:09,758
But how?
243
00:25:19,184 --> 00:25:22,145
The night before
the carcass is discovered,
244
00:25:22,187 --> 00:25:25,565
the Nsefu pride
is on the prowl.
245
00:25:25,607 --> 00:25:28,151
And the yearling
has joined the hunt.
246
00:25:31,363 --> 00:25:34,950
They single out a buffalo
at the back of the herd
247
00:25:34,992 --> 00:25:36,702
and launch an attack.
248
00:25:41,832 --> 00:25:43,500
Surrounding the buffalo,
249
00:25:43,542 --> 00:25:46,045
the female lions
come into their own.
250
00:25:46,712 --> 00:25:48,464
(GROANS)
251
00:26:00,642 --> 00:26:02,727
The yearling hangs back,
252
00:26:02,770 --> 00:26:06,023
as it takes
experience and knowledge
to bring down a buffalo.
253
00:26:30,005 --> 00:26:31,006
(THUDDING)
254
00:26:50,692 --> 00:26:53,904
But the young lion
gets stuck in the wrong place.
255
00:26:56,156 --> 00:26:59,826
Trapped underneath
the buffalo,
he is trampled.
256
00:27:07,417 --> 00:27:09,461
The damage is invisible,
257
00:27:09,503 --> 00:27:11,672
but massive internal injuries
258
00:27:11,713 --> 00:27:13,882
kill him within
just a few hours.
259
00:27:16,468 --> 00:27:19,680
An animal that
is normally prey
became the killer,
260
00:27:21,807 --> 00:27:24,268
though in this case,
it was self-defense.
261
00:27:28,897 --> 00:27:34,736
Every year, many lions
are injured by these
formidable herbivores.
262
00:27:34,778 --> 00:27:36,780
The buffalo was the culprit.
263
00:27:38,323 --> 00:27:42,202
The lion carcass case
is solved.
264
00:27:48,792 --> 00:27:51,378
The problem
with solving crimes out here
265
00:27:51,420 --> 00:27:53,881
is that evidence
disappears quickly.
266
00:27:56,842 --> 00:28:00,012
The clean-up process
for this young lion
has begun with
267
00:28:00,053 --> 00:28:03,723
some of the smallest residents
of Luangwa, the ants.
268
00:28:06,643 --> 00:28:08,728
Ants out here
can be formidable.
269
00:28:11,815 --> 00:28:13,859
Some have a ferocious bite,
270
00:28:13,901 --> 00:28:17,321
and they will often travel
in swarms of thousands,
271
00:28:17,362 --> 00:28:19,698
destroying everything
in their path.
272
00:28:23,035 --> 00:28:24,912
When looking for a carcass,
273
00:28:24,953 --> 00:28:27,581
the ants send out
small search parties.
274
00:28:33,587 --> 00:28:38,008
This impala was dragged
nine feet up a tree
by a leopard.
275
00:28:40,636 --> 00:28:45,391
It’s a strategy
to protect the kill
from other predators.
276
00:28:45,432 --> 00:28:52,189
Lions, wild dogs, and hyenas
would all steal a free meal,
given half a chance.
277
00:28:53,398 --> 00:28:54,399
(HYENA SCREECHING)
278
00:28:58,695 --> 00:29:00,989
It may be safe from them
279
00:29:01,990 --> 00:29:03,825
but not from the ants.
280
00:29:05,369 --> 00:29:08,080
Once they locate
a body like this,
281
00:29:08,121 --> 00:29:11,750
they release a pheromone
to guide in
the rest of the colony.
282
00:29:18,131 --> 00:29:22,093
They use sharp pincers
to tear off tiny chunks
of meat.
283
00:29:31,270 --> 00:29:34,982
But they aren’t
the only ones cleaning up
death in the valley.
284
00:29:39,778 --> 00:29:42,489
These two scavengers,
285
00:29:42,531 --> 00:29:45,367
a hooded vulture
and a fish eagle,
286
00:29:45,409 --> 00:29:47,995
have spotted their food
from the sky
287
00:29:48,036 --> 00:29:52,165
and come down for a feast.
288
00:29:52,207 --> 00:29:55,544
But they need to wait
for their larger cousins
to arrive.
289
00:29:55,585 --> 00:29:57,670
(SQUAWKING LOUDLY)
290
00:30:00,882 --> 00:30:06,137
White backed vultures
have powerful beaks
that can open up the carcass.
291
00:30:09,558 --> 00:30:13,062
With eyesight
eight times better
than a human’s,
292
00:30:13,103 --> 00:30:16,523
they can spot a kill
from up to a mile away.
293
00:30:27,743 --> 00:30:31,830
In a matter of minutes,
there can be hundreds
feeding on a carcass.
294
00:30:34,041 --> 00:30:37,419
Using their strong beaks
to rip and tear,
295
00:30:37,461 --> 00:30:41,090
they gorge themselves
on soft muscle
and organ tissue.
296
00:30:47,304 --> 00:30:50,015
But the racket
attracts another scavenger.
297
00:30:57,481 --> 00:31:00,359
Hyenas’ hearing
is exceptional,
298
00:31:00,400 --> 00:31:05,655
so acute they can even hear
a predator killing prey
six miles away.
299
00:31:05,697 --> 00:31:06,698
(CACKLING)
300
00:31:09,534 --> 00:31:12,912
They’re one of the most
efficient eaters
on the plains,
301
00:31:12,954 --> 00:31:16,875
able to devour
more of a carcass
than any other animal.
302
00:31:18,960 --> 00:31:20,712
Their powerful jaws
are capable
303
00:31:20,754 --> 00:31:23,507
of snapping
and crushing bone
with ease.
304
00:31:29,262 --> 00:31:31,055
Nothing goes to waste.
305
00:31:47,322 --> 00:31:51,368
High levels
of hydrochloric acid
in their stomachs
306
00:31:51,410 --> 00:31:56,749
enable them to digest bones,
horns, ligaments and hair.
307
00:32:15,684 --> 00:32:18,103
Once the hyenas move away,
308
00:32:18,145 --> 00:32:21,565
the vultures vacuum up
any last bone fragments.
309
00:32:25,026 --> 00:32:26,653
Between them,
310
00:32:26,695 --> 00:32:29,865
they are the ultimate
crime scene clean-up crew.
311
00:32:32,409 --> 00:32:37,205
These waste disposal experts
are a vital cog in
the valley ecosystem.
312
00:32:40,792 --> 00:32:43,545
But their efficiency
can make it hard to find
313
00:32:43,587 --> 00:32:46,799
any clues as to why
an animal met its end.
314
00:32:52,679 --> 00:32:55,390
There is one last
mystery killing to solve.
315
00:33:10,405 --> 00:33:14,159
This is a 2,000 pound
male buffalo.
316
00:33:18,747 --> 00:33:20,374
At 15 years,
317
00:33:20,415 --> 00:33:23,543
he’s one of
the older members
of the herd.
318
00:33:28,006 --> 00:33:29,841
An experienced male,
319
00:33:29,883 --> 00:33:32,302
he’s fought off
many lions in his time
320
00:33:34,554 --> 00:33:36,723
and fathered
numerous offspring.
321
00:33:39,309 --> 00:33:43,814
But in the late afternoon,
a horrifying scene
is discovered.
322
00:33:55,534 --> 00:33:58,328
Buffalo are
the ultimate prey species.
323
00:34:01,122 --> 00:34:04,876
Already being devoured
by vultures,
324
00:34:04,918 --> 00:34:08,296
this stalwart male is found
facedown in the mud.
325
00:34:10,257 --> 00:34:12,593
Evidence is quickly being lost
326
00:34:12,634 --> 00:34:16,096
as the more
dominant birds fight
for the best cuts of meat.
327
00:34:23,436 --> 00:34:26,314
Dozens descend.
328
00:34:26,356 --> 00:34:30,735
A carcass like this
can be completely consumed
in a matter of hours.
329
00:34:37,117 --> 00:34:39,411
But vultures aren’t killers.
330
00:34:41,871 --> 00:34:45,375
They must rely
on something else
to do the dirty deed.
331
00:34:50,922 --> 00:34:54,759
But who would have
left the vultures
this incredible buffet?
332
00:34:58,638 --> 00:35:00,390
Let’s take a look.
333
00:35:04,894 --> 00:35:08,272
There are three possible
suspects in this case.
334
00:35:13,111 --> 00:35:16,364
First, a group of lions
from the Nsefu pride.
335
00:35:19,993 --> 00:35:22,245
The Hot Springs wild dog pack.
336
00:35:27,959 --> 00:35:31,880
Or Olimba,
the solitary resident leopard.
337
00:35:33,131 --> 00:35:35,133
Let’s analyze the suspects.
338
00:35:43,808 --> 00:35:46,060
The Nsefu pride, as we know,
339
00:35:46,102 --> 00:35:49,063
are experienced
buffalo killers.
340
00:35:49,105 --> 00:35:52,233
So they are high
on the suspect list.
341
00:35:56,529 --> 00:36:00,742
They have the pack power
to take on a buffalo
342
00:36:00,784 --> 00:36:04,705
and these serial killers
have a long list
of previous victims.
343
00:36:08,583 --> 00:36:11,711
But 70% of their hunts fail,
344
00:36:11,753 --> 00:36:14,297
so were they successful
this time?
345
00:36:28,895 --> 00:36:30,438
Another group hunter.
346
00:36:37,112 --> 00:36:41,033
The Hot Springs pack
are wild dogs
at the top of their game.
347
00:36:48,248 --> 00:36:52,419
These African assassins
have the perfect
team hunting strategy.
348
00:36:54,045 --> 00:36:55,588
(YIPPING)
349
00:36:55,630 --> 00:36:58,174
They travel huge distances
looking for prey.
350
00:37:05,181 --> 00:37:07,684
Once they spot a target,
351
00:37:07,726 --> 00:37:11,855
their strategy is
to run it to exhaustion
over long distances.
352
00:37:15,358 --> 00:37:16,359
(BARKS)
353
00:37:18,653 --> 00:37:23,575
At best, their prey only has
a 30% chance of escaping.
354
00:37:26,327 --> 00:37:30,331
Wild dogs are
the most efficient
of all the African hunters.
355
00:37:43,803 --> 00:37:47,390
(YIPPING)
356
00:37:47,432 --> 00:37:50,810
Once they’ve made a kill,
they need to be on high alert.
357
00:37:52,562 --> 00:37:54,064
There are thieves about.
358
00:37:59,486 --> 00:38:01,697
There’s no time
for table manners.
359
00:38:01,738 --> 00:38:06,952
Speed is of the essence
to avoid their prey
being stolen.
360
00:38:06,993 --> 00:38:13,458
This pack of 12
will eat 220 pounds
of meat in just 15 minutes.
361
00:38:18,630 --> 00:38:20,924
But what about
the buffalo victim?
362
00:38:22,801 --> 00:38:24,845
Could this pack
have taken him down?
363
00:38:34,312 --> 00:38:39,234
Buffalo weigh well over
30 times more than a wild dog,
364
00:38:39,275 --> 00:38:41,068
and tower over them, too.
365
00:38:43,655 --> 00:38:48,618
Nevertheless, wild dogs
show no fear and are often
seen taunting them.
366
00:38:51,704 --> 00:38:56,626
So did the Hot Springs pack
use their strength in numbers
to commit the crime?
367
00:39:06,719 --> 00:39:09,513
There’s one more suspect
to consider.
368
00:39:17,230 --> 00:39:18,565
Olimba.
369
00:39:18,606 --> 00:39:20,441
She’s a fit, young leopard.
370
00:39:22,861 --> 00:39:27,074
Her territory includes
the location where
the victim’s body was found.
371
00:39:29,617 --> 00:39:32,787
She’s been seen
eating buffalo before,
372
00:39:32,829 --> 00:39:34,622
but was she just scavenging?
373
00:39:40,670 --> 00:39:45,091
Could she really defeat
a Luangwa heavyweight
on her own?
374
00:39:51,431 --> 00:39:54,059
She already has
a criminal record,
375
00:39:54,100 --> 00:39:56,728
but her past victims
were mostly impala.
376
00:39:59,397 --> 00:40:03,359
Impala are ten times
lighter than a buffalo
377
00:40:03,401 --> 00:40:06,279
and the leopard
can take them down
with ease.
378
00:40:11,784 --> 00:40:14,954
Her tactic is to creep
as close as possible.
379
00:40:19,125 --> 00:40:25,089
Superbly camouflaged,
she uses stealth
to move almost unnoticed.
380
00:40:39,854 --> 00:40:44,484
Her powerful jaws
grip her victim
in a lethal stranglehold.
381
00:40:49,322 --> 00:40:52,575
Impala are perfect prey.
382
00:40:52,617 --> 00:40:57,163
Small enough for
a single leopard to take down
with little risk of injury,
383
00:40:59,832 --> 00:41:03,336
but large enough to provide
several hearty meals.
384
00:41:11,010 --> 00:41:12,678
On the flip side,
385
00:41:12,720 --> 00:41:16,349
buffalo are 20 times
heavier than a leopard
386
00:41:18,559 --> 00:41:23,981
and well-armed with horns that
can inflict serious injury,
or even death.
387
00:41:30,530 --> 00:41:33,366
Could Olimba’s
stealthy tactics
have helped her
388
00:41:33,408 --> 00:41:35,702
to achieve
the near impossible?
389
00:41:45,253 --> 00:41:49,466
We have the motives
and killing strategies
for each of our suspects.
390
00:41:52,802 --> 00:41:57,015
But who or what is responsible
for the victim’s death?
391
00:41:59,308 --> 00:42:00,810
Let’s review the evidence.
392
00:42:05,356 --> 00:42:11,237
Wild dogs will
devour their prey
as soon as they bring it down.
393
00:42:11,279 --> 00:42:15,116
But on this body,
there is still plenty of meat
left for the vultures.
394
00:42:19,328 --> 00:42:23,249
Dogs in packs of 30
or more have been
known to kill buffalo
395
00:42:26,669 --> 00:42:29,881
but the Hot Springs pack
only has 12 members,
396
00:42:31,632 --> 00:42:33,509
not enough to be the killers.
397
00:42:36,387 --> 00:42:41,726
If it wasn’t the wild dogs,
was it one of the big cats?
398
00:42:41,768 --> 00:42:46,773
The Nsefu lions or Olimba
would have taken huge chunks
out of the buffalo.
399
00:42:52,987 --> 00:42:55,448
But before the vultures
had their way,
400
00:42:55,490 --> 00:42:58,118
the carcass seemed
remarkably intact.
401
00:42:58,159 --> 00:43:01,454
(FLIES BUZZING)
402
00:43:01,496 --> 00:43:04,791
What’s more,
there are thousands
of buffalo footprints
403
00:43:04,832 --> 00:43:05,833
at the scene.
404
00:43:09,003 --> 00:43:11,547
And not one big cat print.
405
00:43:16,010 --> 00:43:18,262
Leopards and lions
are ruled out.
406
00:43:20,765 --> 00:43:23,935
But if it wasn’t cats or dogs,
407
00:43:23,976 --> 00:43:25,769
what did kill the victim?
408
00:43:30,525 --> 00:43:32,819
A new suspect has emerged.
409
00:43:38,282 --> 00:43:41,327
The Luangwa Valley
is dotted with lagoons,
410
00:43:45,081 --> 00:43:47,834
vital watering holes
for hundreds of animals.
411
00:43:52,463 --> 00:43:54,966
During the dry season,
they evaporate
412
00:43:55,007 --> 00:43:58,219
and accessing
the dwindling water
becomes trickier.
413
00:44:03,975 --> 00:44:06,936
But there’s an upside
that makes it
worth the struggle.
414
00:44:08,855 --> 00:44:12,108
In addition
to quenching their thirst,
415
00:44:12,150 --> 00:44:16,363
a mud bath is the perfect way
to cool down
in the heat of the day.
416
00:44:18,739 --> 00:44:22,076
The buffalo cover themselves
in this natural sunscreen.
417
00:44:27,373 --> 00:44:33,588
So, how did
this scene of tranquillity
turn into tragedy?
418
00:44:33,629 --> 00:44:37,049
Who or what
is the mystery killer?
419
00:44:45,141 --> 00:44:47,560
Let’s examine the evidence
more closely.
420
00:44:55,610 --> 00:44:57,570
As the day began to warm,
421
00:44:57,612 --> 00:45:00,281
the buffalo herd
crossed the muddy gauntlet
422
00:45:00,323 --> 00:45:04,577
to get a well-deserved drink
and a soothing mud bath.
423
00:45:06,412 --> 00:45:10,249
But soon,
the temperature sky-rocketed,
424
00:45:10,291 --> 00:45:13,669
sucking the last
of the moisture
from the cooling mud.
425
00:45:17,006 --> 00:45:19,842
Mud can set like concrete,
426
00:45:19,884 --> 00:45:21,302
trapping its victims.
427
00:45:25,056 --> 00:45:27,892
The buffalo spa
became a death trap.
428
00:45:33,022 --> 00:45:34,732
When the herd moved on,
429
00:45:36,859 --> 00:45:38,736
he was stuck fast.
430
00:45:44,533 --> 00:45:47,870
Unable to escape, hours later,
431
00:45:47,912 --> 00:45:52,542
exhausted and dehydrated,
the buffalo died.
432
00:46:04,428 --> 00:46:08,265
Drought is
a more deadly killer
than any predator.
433
00:46:11,185 --> 00:46:14,313
The buffalo carcass case
is solved.
434
00:46:30,871 --> 00:46:34,208
Every carcass
in the Luangwa Valley
has a story.
435
00:46:37,712 --> 00:46:40,465
The cause of death
can be surprising
436
00:46:40,506 --> 00:46:43,759
as killers come
in all shapes and sizes.
437
00:46:47,888 --> 00:46:50,724
Carnivores aren’t
always the bad guys
438
00:46:56,105 --> 00:47:08,826
and herbivores aren’t
always the victims.
439
00:47:08,868 --> 00:47:12,205
With our three
mysteries solved,
440
00:47:12,246 --> 00:47:16,125
it’s only too clear
that out here
in this harsh environment,
441
00:47:18,085 --> 00:47:20,671
death can come in many guises.
