Robert Weber, 35, of Concord, California, was abducted, shot, and his body was found in Colusa County in August 1985. Investigators later linked his murder to John Sapp, a drifter who had spent nearly two decades in various state and county facilities before his arrest in May 1986 on multiple murder allegations.

Sapp was tied to other victims, including John Abono, 22, and Elizabeth Duarte, 24. He was arrested after a weapons charge in Nevada County led to confessions that implicated him in killings and to searches of sites he said contained additional victims. Sapp was convicted in Contra Costa County Superior Court in 1991 for the murders of Weber, Duarte and Abono; the California Supreme Court later upheld his death sentence.

If anyone knew Robert Weber, where he worked, or saw him in Concord or Colusa County in 1985, please come forward with information.
