Shanique Marie, 25, a mother of four from San Francisco, was killed on May 11, 2016, in a shooting on Highway 4 in Pittsburg, California. The CHP says the Westbound vehicle she and a male companion were in was struck by gunfire near Railroad Avenue at about 10:47 a.m.; the car then hit a dirt embankment and overturned. Marie suffered a fatal gunshot wound to the torso and was pronounced dead at the scene; the male passenger survived with injuries.

Investigators describe the attack as likely gang-related and linked it to a pattern of highway shootings in the East Bay. A newer-model white Mercedes sedan with paper plates was reported fleeing the scene. No arrests have been announced and the suspect or suspects remain unidentified. Marie had recently earned her high school diploma through the San Francisco Conservation Corps and was remembered by family and neighbors as a devoted mother and positive presence in her community.

Does anyone have information about that white Mercedes or the events on Highway 4 that morning?
