Hearse driving redneck Donald Pee Wee Gaskins may only have stood 5'4" tall, but he would earn himself the nickname of the meanest man in America and become South Carolina's biggest mass murderer when police discovered his boasts of having his own private graveyard were real. Cops would eventually discover the bodies of 13 men women and children, but in prison Gaskins would claim to have killed more than a hundred - raping, torturing and then sinking their bodies in the swamps. And Gaskins would add to his tally in prison, pulling off the extraordinary murder of a death row inmate - blowing him up by remote control. But what created this feared psychopath and sexual sadist? Was it nature or nurture? The men that knew and pursued him, leading experts, and the loving daughter he confessed to examine whether Pee Wee Gaskins was born to kill?
