Dean Corll was an American serial killer. Born in 1939 in Fort Wayne, Indiana, he served in the military briefly, but was discharged after only ten months when his mother needed medical care.
By 1970, Corll had started murdering young men around his home, mostly hitchhikers whom he hoped would not be missed. Along with two younger accomplices, David Brooks and Elmer Henley, he is known to have killed at least 27 teenaged boys and young men.
Corll’s own death occurred when he lost an argument over possession of a handgun with Henley, who shot the older man six times. Henley then called the police, and confessed to his part in killing Corll, and participating in the murders of others.
Also known as ‘The Kindly Killer’ and ‘The Muswell Hill Murderer’, Dennis Nilsen was 33 years old when he made his first killing, that of Stephen Holmes. Holmes, like most of Nilsen’s victims, was a teenaged male. Nilsen strangled and drowned him, then indulged his necrophiliac tastes by masturbating twice over the body. Unlike his later victims (and while Nilsen was convicted of six murders, his own confession to police lists 15), Holmes was not dissected after his death.
Nilsen would finally be caught in 1983, and sentenced to life imprisonment. It is known that he killed at least 12 people (although he claimed more) and attempted at least seven more murders. At the time of this writing, he remains in HMP Full Sutton, a maximum security prison in Yorkshire.
