Keyon Marcell Tyson was 24 when he was shot to death on June 22, 2012, outside his apartment on North Golden Avenue in San Bernardino. Police responded to reports of shots fired and found Tyson on the sidewalk; he was pronounced dead at the scene.

Neighbors described him as friendly and said there was no clear reason he would have been targeted. Although numerous people were reportedly present during the shooting, investigators struggled to gather information because many witnesses were unwilling to cooperate, citing fear of retaliation. The case remains without a clear motive and was one of several homicides in San Bernardino that year.

If anyone knew Keyon, witnessed the shooting, or has information that could help, please come forward to the appropriate investigators.
