Who is the Most Intelligent Serial Killer ()

Synopsis:
Edmund Emil "Big Ed" Kemper III (born December 18, 1948), also known as "The Co-ed Killer", is an American serial killer and necrophile who was active in California in the early 1970s. He started his criminal life by murdering his grandparents when he was 15 years old. Kemper later killed and dismembered six female hitchhikers in the Santa Cruz area. He then murdered his mother and one of her friends before turning himself in to the authorities days later. Kemper is noted for his imposing physicality and high intelligence, standing 6 ft 9 inches (2.06 m), weighing over 300 pounds (140 kg), and having an IQ of 145.

Theodore Robert "Ted" Bundy (born Theodore Robert Cowell; November 24, 1946 -- January 24, 1989) was an American serial killer, rapist, kidnapper, and necrophile who assaulted and murdered numerous young women and girls during the 1970s and possibly earlier. After more than a decade of denials, he confessed shortly before his execution to 30 homicides committed in seven states between 1974 and 1978; the true total remains unknown, and could be much higher.

Bundy was regarded as handsome and charismatic by his young female victims, traits he exploited in winning their trust. He typically approached them in public places, feigning an injury or disability, or impersonating an authority figure, before overpowering and assaulting them at a more secluded location. He sometimes revisited his secondary crime scenes for hours at a time, grooming and performing sexual acts with the decomposing corpses until putrefaction and destruction by wild animals made further interaction impossible. He decapitated at least 12 victims and kept some of the severed heads in his apartment for a period of time as mementos. On a few occasions, he simply broke into dwellings at night and bludgeoned victims as they slept.

Herman Webster Mudgett (May 16, 1861[1] -- May 7, 1896), better known under the alias of Dr. Henry Howard Holmes, was one of the first documented American serial killers in the modern sense of the term. In Chicago at the time of the 1893 World's Fair, Holmes opened a hotel which he had designed and built for himself specifically with murder in mind, and which was the location of many of his murders. While he confessed to 27 murders, of which four were confirmed, his actual body count could be as high as 200. He took an unknown number of his victims from the 1893 Chicago World's Fair, which was less than two miles away, to his "World's Fair" hotel.

The case was notorious in its time and received wide publicity through a series of articles in William Randolph Hearst's newspapers. Interest in Holmes' crimes was revived in 2003 by Erik Larson's The Devil in the White City: Murder, Magic, and Madness at the Fair That Changed America, a best-selling non-fiction book that juxtaposed an account of the planning and staging of the World's Fair with Holmes' story. His story had been previously chronicled in The Torture Doctor by David Franke (1975), Depraved: The Shocking True Story of America's First Serial Killer by Harold Schechter (1994), and chapter VI "The Monster of Sixty-Third Street" of Gem of the Prairie: An Informal History of the Chicago Underworld by Herbert Asbury (1940, republished 1986).

Theodore John "Ted" Kaczynski, PhD (/kəˈzɪnski/ ka-ZIN-skee, or ka-CHIN-skee; Polish: Kaczyński, pronounced [kaˈt͡ʂɨȷ̃skʲi]; born May 22, 1942), also known as the "Unabomber", is an American terrorist, mathematician, social critic, and Neo-Luddite. Between 1978 and 1995, Kaczynski engaged in a nationwide bombing campaign against modern technology, planting or mailing numerous home-made bombs, killing three people and injuring 23 others.

Kaczynski was born and raised in Chicago, Illinois. While growing up in Chicago he was a child prodigy, excelling academically from an early age. Kaczynski was accepted into Harvard University at the age of 16, where he earned an undergraduate degree. He subsequently earned a PhD in mathematics from the University of Michigan. He became an assistant professor at the University of California, Berkeley in 1967 at age 25, but resigned two years later.
