Marshall Prosser, 22, was found shot to death inside his car on 84th Avenue in East Oakland on August 28, 2012. Authorities discovered him after responding to a ShotSpotter alert; he was pronounced dead at the scene.

His killing was recorded amid a sharp rise in Oakland homicides that year, when the city logged 127 homicides and law enforcement faced resource constraints and limited witness cooperation. Marshall’s death is presented as part of a larger pattern of unresolved shootings in East Oakland from that period, underscoring ongoing problems with gun violence and unsolved cases in the city.

Does anyone have information about Marshall, his movements that day, or witnesses who might help the investigation?
