Stephan Weaver, 22, of Bowie and Deandre Ricardo Williams, 23, of Washington, D.C., were arrested on charges of first-degree murder, according to a statement released by county police.

Weaver was arrested on March 26, and Williams was arrested in D.C. on Wednesday, according to police spokesperson Cpl. Erica Johnson. Police have determined the motive to be robbery.

DeSha-Overcash, a 22-year-old senior double majoring in physics and astronomy, was shot to death in his home on 38th Avenue on Jan. 11. The shooting was likely the result of an attempted drug robbery gone awry, police said at the time, based on the presence of marijuana-related paraphernalia found in the house.
