Antone Costa

 

This modern day Marquis de Sade and wannabe flower child left a trail of blood spanning from Provincetown, Massachusetts, to California. All his victims were women who he befriended to get high.

Then he killed them and enjoyed having sex with their mutilated corpses. A police psychiatrist diagnosed him as being schizophrenic. He was found hanged in his prison cell on May 12, 1974.
