Before he became known as the Genesee River Killer, Arthur Shawcross’s violent urges first surfaced in two brutal murders that shocked upstate New York. Long before his killing spree along the Genesee River, Arthur Shawcross’s darkness emerged in 1972, when two young victims vanished under chillingly similar circumstances. In Part One, we trace Shawcross’s early life, the disturbing patterns that began to take shape, and the investigation into his first known murders, crimes that should have been a warning of the horrors yet to come.
