Real life Psycho.
I only post this because this guy had DID and used a knife in his killings. They were extremely brutal, as well. He killed Ashton Kutcher's date and became infamous as the Hollywood Ripper.
"A man dubbed the “Hollywood Ripper” was found guilty Thursday of the murders of two women, including a student who was due to go out with actor Ashton Kutcher the night of her death.
Michael Gargiulo, 43, was convicted of two counts of first-degree murder by a Los Angeles jury who deliberated for four days before reaching their verdict.
Prosecutor Dan Akemon had told jurors that Gargiulo targeted the women in “frenzied knife attacks,” referring to him as a “stone-cold serial killer who preys on women.”
Gargiulo’s lawyers said he denied the killings.
They said there was no evidence Gargiulo was at the scene of the two murders, and indicated that his dissociative identity disorder could have caused him to go into a “fugue” state during a separate attack on a third woman who survived."
"He is also awaiting a separate trial for the earlier 1993 killing of a third woman in the state of Illinois.
Prosecutor Akemon said Gargiulo targeted women who lived near him and waited for the perfect opportunity to attack them at night in or near their homes in “totally planned killings.”
The murdered women had injuries to their breasts, and one was found nearly decapitated, he said."
