Mark Clay, 46, of Rohnert Park was shot and killed on August 12, 2017, in Richmond, California. Officers found his body beneath the bumper of his vehicle on Florida Avenue at Harbor Way South; investigators determined he had been shot multiple times and treated the death as a homicide.

The Richmond Police Department led the investigation but announced no immediate arrests or suspects. Detectives interviewed witnesses and analyzed forensic evidence, but limited eyewitness accounts and difficulty tracing the firearm hampered progress. The case drew community attention, and local groups such as Richmond Ceasefire held walks and vigils to remember Clay and press for action against gun violence.

The investigation remained open and active, with police asking anyone with information to come forward. Did anyone in the Richmond or Rohnert Park area see Mark Clay on or around August 12, 2017, or know anything that could help investigators?
