Two men were shot and killed Wednesday night and early Thursday in separate attacks in Northwest and Southeast Washington, according to D.C. police.

The shooting on Thursday occurred about 3:45 a.m. on a small street off the 1100 block of First Street NW. Police said two men were shot — one in the foot, another several times in the chest. That man died at an area hospital. Police identified him as Andre Wilson, 26, of Northwest Washington.

The shooting occurred several blocks from Tyler House, the scene of a mass shooting in March in which 13 people were wounded, and near the emerging neighborhood of NoMA, short for north of Massachusetts Avenue. The shooting took place near vacant lots and parking lots but also a playground and an apartment complex under construction.

Police have made several arrests in the shooting outside Tyler House and have said it was the result of a dispute between members of neighborhood crews over previous violence. Police said they had just begun their investigation into Thursday’s shooting and did not know if there was a connection. No description was given of the shooter.

The other fatal shooting occurred Wednesday about 10:20 p.m. in the 1600 block of 21st Place SE.

Officer Araz Alali, a D.C. police spokesman, said officers responding to a report of a shooting found a man suffering from several gunshot wounds. Alali said the man was pronounced dead at an area hospital.

Police identified the victim as Rodney Ellis Gardner, 33, of Northeast Washington. Authorities said they knew of no motive or suspect in the case.
