- Your next door neighbor may not be exactly
-
who you think they are.
-
(screaming)
-
You might think serial killers are lower intelligence
-
individuals who are not smart enough to know the difference
-
between right and wrong,
-
but the terrifying reality is quite the opposite.
-
These are the 10 smartest serial killers of all time.
-
Number one is Ted Kaczynski.
-
Ted Kaczynski, better known as the Unabomber,
-
was born in Chicago, Illinois, on May 22nd, 1942.
-
As a child, Kaczynski was academically gifted,
-
and in the fifth grade he received an IQ score of 167.
-
His high intelligence got him accepted to Harvard
-
at only 16 years old.
-
During his time there, he took part in brutal psychological
-
testing that was meant to study stress.
-
This experience and his young age are believed to have
-
contributed to him becoming socially isolated.
-
He went on to earn his Ph.D and was a professor
-
at Berkeley, but his belief that humanity was becoming
-
immoral and controlled by technology led him to go
-
off the grid.
-
For 18 years, he lived in a cabin in the woods of Montana
-
where he built small bombs, sending them to targets
-
across the United States.
-
The bombs, which were impossible to trace back to Kaczynski,
-
killed three people and injured 23 more.
-
It was only because his own brother recognized
-
his handwriting on a published copy of his manifesto
-
that the FBI captured Kaczynski on April 3rd, 1996.
-
He is still in prison serving a life sentence.
-
Number two is Carroll Cole.
-
Born on May 9th, 1938, in Iowa, Carroll Cole was considered
-
to be extremely intelligent with an IQ of 152.
-
But his terrible home life and developing mental issues
-
eventually turned him into a coldblooded serial killer.
-
Cole's mother was incredibly abusive.
-
She would make him watch her entertain men
-
and would beat him constantly.
-
Cole committed his first murder as a child
-
when he drowned one of his classmates.
-
As an adult, he would commit his crimes while in
-
a violent rage, including strangling an 11-year-old girl.
-
He spent time in and out of prison and mental hospitals,
-
but once he was released he started drinking
-
and would kill women that he met that reminded him
-
of his mother.
-
In November of 1980, Cole was finally caught and confessed
-
to 14 murders, but there are possibly even more
-
that he couldn't remember.
-
He was given the death penalty and died by lethal injection
-
on December 6th, 1985.
-
Number three is Jack the Ripper.
-
There are tons of theories as to who Jack the Ripper
-
really was.
-
From a local surgeon to possibly Queen Victoria's grandson
-
Prince Albert, nobody knows.
-
But one thing is for sure, he was highly skilled
-
and knowledgeable in human anatomy.
-
The infamous, anonymous serial killer murdered at least
-
five women in the Whitechapel district of London, England,
-
between 1888 and 1881.
-
The murders were often extremely gruesome
-
with the bodies left horrifically mutilated,
-
complete with organs missing.
-
The state the bodies were found in convinced many
-
that he could have been a surgeon or even a butcher.
-
During the time of the murders, hundreds of letters,
-
supposedly from the killer, were sent to the press.
-
Most of them turned out to be fakes, but a few very likely
-
were sent from the man himself,
-
including one signed Jack the Ripper.
-
One even correctly promised details of the next murder.
-
Jack the Ripper seemed to disappear after his final murder
-
of Mary Kelly, and despite developments in forensic
-
technology, he evaded police and was never identified.
-
Number four is H.H. Holmes.
-
Herman Mudgett, also known as Dr. Henry Howard Holmes
-
or H.H. Holmes, was born on May 16th, 1861,
-
in Gilmanton, New Hampshire.
-
Holmes moved to Chicago in 1886 and purchased a lot
-
where he started to build a large hotel
-
dubbed by locals The Castle.
-
During the contruction process, Holmes would frequently
-
hire and then quickly fire entire teams
-
of construction workers after sections of the hotel
-
were completed.
-
This was all part of his grand plot,
-
because he didn't want any of the workers knowing
-
the full picture of the building plans,
-
which in reality was that the second floor was to become
-
a massive murder complex.
-
This true house of horrors was basically a murder maze,
-
complete with soundproof rooms, doors that led to nowhere,
-
bedrooms linked with gas lines, and torture chambers.
-
The hotel was up and running during the 1893 World's Fair
-
which was ideal since people were less likely to notice
-
a few tourists amongst thousands going missing.
-
He was eventually caught and hanged in 1894,
-
but not before he killed an estimated 200 guests.
-
Number five is Andrew Cunanan.
-
Andrew Cunanan was born in National City, California,
-
on August 31st, 1969.
-
He was a gifted young man with an IQ of 147
-
and was apparently fluent in seven different languages,
-
but he also had a passion for the high class lifestyle
-
and was obsessed with fame.
-
During the 1990s, he would frequent gay clubs
-
in San Francisco and eventually began prostituting himself
-
to wealthy, older men and began using hard drugs.
-
Then, on April 25th, 1997, he began a three-month
-
murder spree that took the lives of five men.
-
However, he taunted police,
-
taking them on a cross country manhunt.
-
Cunanan was quickly put on the FBI's 10 most wanted list
-
before returning to Miami and reentering the party scene.
-
Then, on the morning of July 15th, 1997,
-
Cunanan shot and killed famous fashion designer
-
Gianni Versace outside his home without any clear motive.
-
And eight days later on July 23rd, the FBI finally
-
tracked him to a houseboat, but he committed suicide,
-
shooting himself before he could be arrested.
-
Number six is the Zodiac Killer.
-
During the late 1960s, the Zodiac Killer
-
had the citizens of northern California living in terror.
-
Between December 1968 and October 1969,
-
the Zodiac completely baffled law enforcement
-
with a series of five confirmed murders though it's believed
-
he could've been responsible for many more.
-
Between 1969 and 1974, the Zodiac Killer began to contact
-
the media and investigators.
-
He sent a series of letters over the years,
-
including four ciphers, but despite attempts from some of
-
the smartest people in the world,
-
only one has ever been solved.
-
The Zodiac claimed if the ciphers were ever solved,
-
he would reveal his identity and would help police find him.
-
The one decoded cipher revealed his motive for the murders
-
was simply fun.
-
It also revealed that the victims would become his slaves
-
in the afterlife.
-
No suspect has ever been named,
-
and no one has ever been charged.
-
The case remains open to this day.
-
Number seven is Israel Keyes.
-
Israel Keyes, born January 7th, 1978, in Richmond, Utah,
-
was a former soldier in the U.S. Army honorably discharged
-
in 2001.
-
However it was later discovered he was linked to the murders
-
of at least 11 people with more killings possibly committed
-
outside of the United States.
-
He spent years studying famous serial killers,
-
including Ted Bundy, all in an effort to perfect
-
his own murderous methods and avoid detection.
-
Unlike most killers, investigators were unable
-
to profile him because he never murdered close to home
-
or even in the same area twice.
-
He would fly all over the country and drive
-
for thousands of miles to collect his so-called murder kits
-
that he had hidden years earlier.
-
The kit consisted of things like plastic bags, shovels,
-
and cleaning chemicals.
-
He would choose his victims at random to avoid falling into
-
any predictable patterns and would rob banks to fund
-
his jet-setting murder sprees.
-
When he was caught in Texas on March 13th, 2012,
-
he confessed to some of the killings,
-
but on December 12th of that year, he killed himself
-
while in his prison cell awaiting trial.
-
It would appear justice was never served on this monster.
-
Number eight is Edmund Kemper.
-
Edmund Kemper was born in Burbank, California,
-
on December 18th, 1948, and was diagnosed
-
as a criminally insane juvenile after he murdered
-
his grandparents at the age of only 15 years old.
-
While serving time in an institution, he received a score
-
of 145 on an IQ test but was also diagnosed
-
with paranoid schizophrenia and psychosis.
-
He put his intellect to use when he managed to study
-
the psychological evaluation tests at the institution
-
and memorized the correct answers.
-
This allowed him to fake his sanity and earn
-
an early release into society when he was only 21 years old.
-
However only a couple years later,
-
he began a horrifying killing spree.
-
Kemper, who was six foot two and 250 pounds,
-
got the nickname the Co-Ed Killer after he kidnapped
-
and murdered six young women between May of 1972
-
and April of 1973.
-
His spree ended on April 20th, 1973, when he murdered
-
his mother and her best friend,
-
after which he phoned the police and calmly confessed.
-
He was sentenced to life in prison on November 3rd, 1973.
-
Number nine is Rodney Alcala.
-
Born in San Antonia, Texas, on August 23rd, 1943,
-
Alcala is a convicted serial killer who murdered
-
at least eight women and potentially up to 120 more.
-
Early on, Alcala was recognized for
-
his exceptional intelligence with an IQ score of 160.
-
In 1978, during his crime spree, he was a contestant
-
on the show The Dating Game and was chosen as the winner.
-
Luckily his date decided not to go out with him
-
after she met him and thought he was different.
-
Alcala told his victims he was a photographer
-
and would lure them to remote locations promising
-
to make them famous.
-
When he was caught on July 24th, 1979, police found
-
over 1,000 photos of young women and boys,
-
many of whom have never been identified.
-
Alcala's attorneys managed to overturn guilty verdicts
-
and death sentences twice, but during his third trial
-
in 2010, Alcala defended himself and he was finally
-
found guilty on all charges.
-
And number 10 is Ted Bundy.
-
Born in Burlington, Vermont, on November 24th, 1949,
-
Ted Bundy was a psychopathic serial killer
-
with a high IQ of 136.
-
Bundy spent time studying criminal investigators
-
and psychology in order to perfect his methods,
-
becoming one of the most infamous killers of all time.
-
He was extremely adept at using his good looks
-
and natural charisma to lure in unsuspecting victims.
-
He would often pretend he was injured or an authority figure
-
to gain a woman's trust before he would attack them.
-
Bundy would take care to hide or change distinct features
-
of his appearance, making it difficult for witnesses
-
to recognize him.
-
He also never left any fingerprints or conclusive
-
physical evidence at crime scenes and never used guns.
-
He murdered a total of 36 women, though possibly many more,
-
until he was finally caught on August 16th, 1975.
-
He even acted as his own attorney and made two escapes
-
while in custody, one from the prison library
-
during a recess in his own trial.
-
But ultimately he was caught and given the electric chair
-
on January 24th, 1989.
-
This finally putting an end to one of the Earth's
-
most notorious killers.
-
So those are the 10 smartest serial killers of all time.
