Mark Andrew Orach, 20, of Orange, California, was murdered on October 5, 1976. His death was by a gunshot to the head and his body was found in Orange County.

The killing was later tied to Patrick Kearney, known as the Trash Bag Killer. Kearney targeted young men, often picking up hitchhikers or men from gay bars, killed them, and disposed of their bodies in trash bags. He confessed to Mark Orach’s murder as part of a string of at least 21 victims from 1962 to 1977.

Kearney was convicted of multiple counts of first-degree murder and is serving twenty-one life sentences without the possibility of parole at Mule Creek State Prison. Who has information about Mark Orach’s last movements or knew him in Orange in 1976?
