David Charles Greer, 37, was shot and killed on December 28, 2017, in Compton. Deputies responded about 10:30 p.m. and found a car stopped in the middle of East Caldwell Street with David and his cousin Brian Keith Greer nearby; both had been shot multiple times and were pronounced dead at the scene shortly after 10:38 p.m. The cousins had spent the day visiting family and planned to take groceries to Brian’s grandmother before the shooting.

David Greer had a prior conviction in a 2001 gang-related shooting, pleading no contest to voluntary manslaughter and serving a sentence that ended five days before this killing; reports say he was trying to turn his life around. Brian Greer had a college education, worked as a social worker, and was preparing to open a Burgerim franchise. Investigators described the deaths as likely the result of a robbery and released a composite of a suspect: a black male about 6 feet tall, 180 pounds, 35–38 years old, last seen leaving in a white four-door car with tinted windows, possibly a Chrysler 200.

What can readers add about sightings, surveillance, or anyone who matches that vehicle or the composite leaving East Caldwell Street that night?
