Ray Copeland was the kind of man who lived by the rule, if you want it, take it. And he did. All the time. Known for stealing livestock in the early 60’s, he spent his time while incarcerated, coming up with new ways to forge checks and pilfer livestock—ways that meant someone would have to die. By the time his scheme was discovered, five men would be dead. And Ray and his wife Faye, aged 76 and 69, would both be sentenced to death.

Between 1968 and 1969, at least four women lost their lives in the Pacific Northwest at the hands of a man with a fetish for shoes. What began as an interest in women’s shoes and clothing at the early age of five years old, developed into a lust for high heels, lingerie and murder.

Gerard John Schaefer was a man one would think could be trusted. He was, after all, a sheriff’s deputy.

And what his fellow officers thought was merely bad judgement, turned into a nightmare of dead bodies, mementos and written stories of lust and murder.

During the 1950’s, locked away in a toolbox at a Los Angeles bungalow was an odd and gruesome collection of mementos. Photographs. All the pictures were of women. Some were bound. Some were gagged.

A many who twenty years before the expression serial killer was a part of the American vocabulary, defined the very phrase.

A man sat on Indiana’s death row professing his innocence for twenty-three years. He wasn’t the man who bound a family of four in Evansville, Indiana with a vacuum cord before shooting them in the head execution style—even though the evidence pointed to him. But in his final days, this dead man walking opened up about what really happened to the Gilligan family, and why it mattered.

From 1967 to 1980, New York City and suburban New Jersey was the playground for a sexual serial killer who would bind, torture, strangle and dismember his victims. His official count of victims stands at nine, but many, including the killer himself think the number is closer to one hundred.
