Cynthia Epps Murder, 1994
This one’s especially grisly. When Buffalo, New York cops responded to a call from a local man who reported finding a body in his back yard, they were horrified to find the hacked-up corpse of single mother Cynthia Epps crammed into a nightstand. The police had no leads, and the case went cold soon after. However, with advances in DNA technology, a routine comparison matched DNA found on Epps’s body with DNA from another rape case – a rape perpetrated by James Fountain, the man who had “discovered” Epps’ body. When detectives presented him with the evidence, Fountain confessed that after having sex with the victim, he stabbed her to death and attempted to hide the body.
