Robert Matas, 31, was found shot to death in San Francisco’s Mission District on June 17, 2009. He was struck multiple times and was pronounced dead at the scene after emergency responders arrived. Early investigative efforts were hindered by a lack of witnesses willing to come forward, and the case was later classified as a cold case by the San Francisco Police Department.

The city has offered financial rewards of between $50,000 and $250,000 for information leading to arrests in unsolved homicide cases, and the Mayor’s Office and the Police Department have urged community cooperation. The homicide of Robert Matas remains unsolved; anyone with information is asked to contact the police tip hotline.
