Harvey seemed off from a young age, though his mother seemed to disagree. By 17 he was in trouble with the law, attacking women on the street. From robbing, fondling, then advancing to rape and murder after a couple stints in prison. Harvey ended up using his camera to lure his targets into a false sense of security. In the end he killed three women and attempted to murder another, but she put up a fight that resulted in his capture. Ultimately he was sentenced to death, which was carried out when Harvey was just thirty one years old.

*BONUS*

Kenneth Parnell kidnapped and assaulted Stephen Stayner, the younger brother of Cary Stayner, who would go on to become the Yosemite National Park Killer. In a family so small, the tragedies are unfathomably large. Kenneth kidnapped and kept Stephen for years, only when he aged out of Kenneth's preference and brought in an additional young boy did Stephen have the strength to take action. He took the newest kidnap victim, Timothy, and carried him back to the police.

Still, for everything that happened, Kenneth served under a decade before getting out. Years later he would be sentenced again, after attempting to have his caregiver buy a 4-year-old. In the end, he died in prison, but not before affecting multiple families exponentially.
