1x9 - First Blood

The Genesee River Killer Serial killer Arthur Shawcross tells a lot of stories about his life before he began to kill. Abuse, bestiality, cannibalism...but is any of it true? And if not, what shaped his trajectory from "Artie Oddball" to murderer? He might have been known for killing women along Rochester's Genesee River, but his first murder was years earlier and the culmination of years of dark fantasies.
