A 53-year-old man was killed in a hit-and-run while walking on the Capital Beltway early Wednesday.

Police have identified the pedestrian as Douglas Edward Diggs, of Capitol Heights.

Diggs apparently was walking in the roadway on the Beltway's Outer Loop. He was fatally struck near the Landover Road exit in Capitol Heights. A Prince George's County police officer discovered the body about 3:20 a.m.

Police say they have no leads on the vehicle that struck Diggs.
