Serial Killers

John Wayne Gacy dresses as a clown, killing boys and putting them into the ground. Ed Kemper had a bad temper beheading his victims seemed simpler. Ed Gein danced in the moonlight, wearing pieces of women who didn't put up a fight. Ted Bundy seeked sympathy, then he killed and showed no mercy. Jeffery Dahmer who was late, finds boys for sex then ate. Dennis Rader was a sick one, torturing and killing til his work was done. What makes them tick? Is it genetics are they born sick? Was it the parents and abuse? No one knows how many are on the lose.
