Police have arrested a 25-year-old Landover man in connection with a fatal shooting Friday night at a District high school.

A D.C. police spokesman said Saturday that Oma Crawford was arrested and charged with murder. Police identified the victim as Ralph Thomas, 36, of Temple Hills.

The shooting occurred about 8:30 p.m. in a parking lot at McKinley Tech high school in Northeast Washington.

Police did not immediately release information about an alleged motive. Earlier, D.C. public school officials said it appeared that the victim, who died at the scene, was not connected with the school system.
