Twenty-nine-year-old Paris Powell was hospitalized in grave condition after being shot in the head shortly after midnight Wednesday. Police say he was taken off life support around 11 p.m. that night.

Witnesses told police that Powell, his wife and their two young daughters were serving a hot meal to a man out of the family’s van when someone opened fire from a passing vehicle. Powell’s pregnant wife and 3-year-old daughter also were hurt in the arm.

Police have not identified any suspects in the shooting, and the motive is unknown.

Friends and family say Powell was known to distribute meals several times a week on the east Oakland streets.
