- Some people can't even cook dinner three or four times a week.
Like, how'd you have time to murder three to four people a week?
- (narrator) Known as the Mangrove Monster,
Daniel Barbosa was born to a rich family in the small town
of Anolaima, Colombia. On May 2nd, 1974,
he saw a nine-year-old girl walking to school.
He then lured her to a secluded area,
raped her, and then strangled her to death.
10 years into his sentence in 1984, Barbosa saw a rowboat
on a beach. He jumped in and started rowing
for the mainland. - In a rowboat?! Boy!
If you don't-- okay. - (narrator) So went on killing
until February 26, 1986. During his arrest, he confessed
to killing 72 girls in Ecuador. - 72?!
What?! - And they thought he was dead
that whole time, so that's why it was kind of
easy for him to do that. That makes sense.
- Oh my god. - (narrator) He said the reason
he chose children was because
he wanted virgins because they cried.
For him, he wanted to punish women's unfaithfulness.
- That's terrible. - (narrator) Before he could get out,
Barbosa was stabbed to death in prison...
- Amazing. - (narrator) ...in November of 1994
by Geovanny Noguera. As it turns out,
he was a nephew of one of Barbosa's previous victims.
- Wow! Oh my god! He was a nephew of a victim?
Dude, that's that retribution type [censored].
- A former Russian police officer has now become the worst serial killer
in the country's history. - (Nadira) The man in question
is Mikhail Popkov. He's nicknamed The Werewolf.
He's 53 years old. - The Werewolf.
He looks like a vampire! - (Nadira) And he raped almost
all of his victims before killing them.
Their ages ranged between 17 and 38 years of age.
In the region, one of... - Russian.
- (Nadira) Now, what he did is he lured women into his car.
He waited for them outside clubs, restaurants, lots of other
public places, and then he would offer them a lift
or fun in the woods, and then he would rape
and kill them with an ax, a knife, a bat, or other hand...
- "But I was a good husband." That title says, "I may be one
of Russia's worst serial killers, but I was a good husband."
Does he not consider himself cheating on his wife
when he's raping these people? - (Nadira) ...weapons.
He's a former policeman, and he used his status...
- And he was a policeman. - (Nadira) ...offering those victims
lifts and... - They end up dying!
Which is terrifying. - (Nadira) ...to the remote areas
that we talked about. Now, the latest twist
in this very disturbing man's tale... - Wow.
- (Nadira) ...is the fact that it's come to light
that, despite being convicted... - 82.
- (Nadira) ...back in January 2015 for the murder of 22 victims,
an additional 60 have been brought to light.
- ADDITIONAL 60! - (whispers) That's so bad.
- (Nadira) That means that the police have--
would bring the total up to 82 victims, making him
the worst serial killer in Russia. - Wow.
(sarcastic) But he was a good husband and dad, though,
even though he was raping and killing other women.
Checks out. - What a loser.
- Wonder if he like remembers all of his victims,
because I know there's that trope of killers keeping trinkets
from each of their kills. And I'm like, I don't even think
it's a trophy. I think it's to remember.
- Pedro Alonso Lopez, AKA the Monster of the Andes
was born on 8th of October in 1948. It is believed that Lopez
started killing young girls in the 1970s.
His victims were usually of poor backgrounds.
He made his way to Peru, where he would lure his victims
to remote areas, committing rape and murder.
By the late '70s, he had made his way to Ecuador,
where dozens of girls began to go missing as well.
- I hate seeing their pictures. - (narrator) Lopez killed
on a regular basis, slaying two, sometimes three girls every week,
every month. - Every week?!
Every. Week. - (narrator) Over the three-year-long
murder rampage, Lopez was proud of his actions.
He told Ron Laytner, the Canadian interviewer,
"I'm the man of the century. No one will ever forget me."
- Look at this [censored]! I don't curse on these channels,
but I will today. Dude, this guy's the biggest [censored].
- It was funny, 'cause in the beginning,
I was like, "Oh, he looks kind of sad,"
but he's so proud of himself. - (narrator) Lopez was eventually
captured as he tried to snatch another young girl in 1980.
Luckily for her, the 10-year-old's mother
saw Lopez walking away hand-in-hand with her daughter Maria.
And then, she started screaming. Lopez then took police
to the graves of 53 of his victims. Two months later in 1980,
he pleaded guilty... - Ugh!
My god. - (narrator) ...to 110 charges
of murders. - Wipe that smile off your face,
you GARBAGE human being. - Imagine being like the mother
or father of your kid, and you look at this guy in court,
and you're seeing him just have this grin on his face.
- (narrator) ...110 charges... He's smitten with himself.
- (narrator) Police said the killer
could have been charged with a total of 350 murders
of missing girls. - Oh my god.
- (narrator) But additional trials in Colombia and Peru would have been
too complex and costly. - Are you serious?
- (narrator) Because of Ecuador's laws at the time, Lopez only received
the maximum sentence of 16 years. - Jesus.
- Wha-- (headphones clatter)
this man, this SCUM,
took the lives of over 300 people, and you gave him a sentence
that was no older than the people he raped and killed.
- (narrator) Pedro Lopez has been a free man
for at least 20 years now, and no one knows where he is
or whether he's still alive. - Oh my god! What?!
- He could be killing right now. That's so dumb!
- (narrator) On December 1999, the local Lahore newspaper
received a disturbing letter. "I have killed and raped
over 100 young boys..." - Ah!
- (narrator) "...between the age of six to sixteen."
- What?! - (narrator) "My victims consist
of orphans and runaway children who lurks
at the streets of Lahore..." - Wow.
- (narrator) "...where I would bring them home, so I could rape them
and strangle them to death. After murdering them,
I would dismember their bodies and immerse them in vats
of hydrochloric acid and would then dump their bodies
at a nearby river." The killer was none other
than Javed Iqbal. He said the purpose of the letter
he gave to the authorities was so that it would make them aware
of how much the children in the streets were neglected.
He promised himself... - What?!
- (narrator) ...that once he's released that he would get back
to the authorities by killing exactly 100 children.
- So, he thought he was doing like a social service?
- (narrator) Not more, not less. Iqbal was sentenced to death,
where he would be executed by strangulation in public
at the place where he would always find his victims.
This punishment is called qisas, the Sharia legal concept of punishment
where the criminal is punished in the same way they tortured
or murdered their victims. - That's good.
I feel like that's fitting. - Low-key, that's fire.
I mean, I'm kind of down with that.
- (narrator) On October 8, 2001, Iqbal...
- Cowards. - (narrator) ...and his accomplice,
Sajid Ahmad, were found dead in their cell as they hung themselves
using their bed sheets. - I hate when they do that.
It's like, you're such a coward. - That's pretty stupid.
That's not even symbolic or anything. It's just dumb. It's petty.
It's petty 'cause you're bad.
- (narrator) In the late '60s, a civil war took place in Colombia,
which would last for decades. In fact, we can still see
the impact this war had on the Colombians' lives.
Thousands of Colombians, including children,
were left homeless and driven to live in the dangerous streets
teeming with crime. These children had no parents
or relatives to take care of them, and they were the perfect targets
for someone with twisted desires, such as Luis Garavito,
world's deadliest serial killer, who was nicknamed The Beast
due to the terrible nature of his crimes.
One would think that being subject to such a terrible childhood,
Garavito would never wish the same thing to happen
to his enemy. However, he did the exact opposite.
- That's always the case with these guys.
They have a crappy childhood. - (narrator) Garavito violated
and murdered homeless boys between the age of six and sixteen.
He was called the beast for a reason.
His victims were tortured and raped and their throats were slashed.
Some of the victims were also dismembered
or decapitated. He went on with his life of crime
for seven years. - Seven years!
- (narrator) It was determined that Garavito killed anywhere
from 150 to 400 boys. - Whoa.
- (narrator) He was sentenced to 1,853 years in prison.
- Not enough. - But because he cooperated
with the police and helped them find
the victims' bodies, his sentence was reduced to 22 years.
And he is scheduled to be released in 2021.
According to his guards, Garavito is a relaxed
and respectful prisoner. - No.
- (narrator) In fact, he is currently studying
to be a politician... - (gasps)
- (narrator) ...and start a career in activism to help abused children.
- The best part is how nonchalant the narrator sounds saying that
as if it isn't the silliest thing in the world.
- He wants to help abused children? Well, at least we'll know
what the abuse was like because the abuser
is telling us about it. - Probably unlikely.
It shouldn't even be a probability.
This should be a 100% keep his ass behind bars.
- I don't understand why there was a boat there.
Like, all this is just, "Huh?" - (React) I know.
- What happened? - Yeah, it's like,
if you can dish it out, you can take it.
- This sounds like some horror movie type [censored].
- There's always that thought of like, "Oh, they've killed
this many more," or "We think they've killed
this many more," or did they remember
even how many they killed?
