District police have arrested a 21-year-old man and charged him with fatally shooting an acquaintance in Southeast Washington on Monday during an argument over a woman, according to authorities.

Ariston Jamal Dickson, of Southeast, was arrested Tuesday evening by members of the Capital Area Regional Fugitive Task Force. He is charged with second-degree murder while armed and could be arraigned in D.C. Superior Court on Wednesday afternoon.

Police said Dickson is charged with shooting 23-year-old Robert Maurice Lesueur, of Northeast, during an argument in the 1700 block of 27th St, SE, which occurred about 1:30 a.m. on Monday.

Officer Anthony Clay, a D.C. police spokesman, said Tuesday that the men had been arguing over a woman. The relationships between the people involved were not clear.

Police responding to a call for an assault in progress found Lesueur inside an apartment, Clay said. He was pronounced dead later that day at a hospital.
