A series of shootings and stabbings left at least 10 victims dead or wounded across the District on Wednesday night and early Thursday, D.C. police said.

Between 9:15 p.m. and 1 a.m., seven people were shot and at least three were stabbed in six incidents. Three victims died. Police would not say whether investigators believe any of the violence was related.

Two men were fatally shot about 11 p.m. in the 700 block of Yuma Street SE, said Officer A. Clay, a department spokesman. One of the victims was shot in the head, and the other suffered from multiple gunshot wounds to the upper body.

About 9:45 p.m., a man was shot and critically wounded in the rear of a home in the 700 block of Quincy Street NW, said Officer Hugh Carew, another police spokesman. The man later died at a hospital.

Two other men were shot just before 10 p.m. in the 900 block of Wahler Place SE, in the Washington Highlands neighborhood, Carew said. One of the men was found at that location, and the other was found nearby, in the 3900 block of Ninth Street SE.

Both men were taken to hospitals with potentially life-threatening wounds, D.C. fire officials said.

About 9:15 p.m., police found two men shot in the 1200 block of Brentwood Road NE, Carew said. Both were expected to survive their injuries.

Another man was stabbed in the 1700 block of H Street NE about 10 p.m., Clay said. The man was stabbed in the neck and is in stable condition at a hospital. There was also a report of a stabbing nearby in the 700 block of 18th Street NE, at about the same time. But details were sketchy, and police said Thursday morning that they are not sure a second stabbing took place.

In the final incident, two other men were stabbed about 12:45 a.m. in the 1300 block of Trinidad Avenue NE. One victim was taken to the hospital by an ambulance, and the other drove himself.

Police made an arrest in the Trinidad Avenue stabbing, but they have not released the name of the person being charged. Police have not made any other arrests in the overnight violence.
