A woman who was shot Monday night in Northwest Washington’s Shaw neighborhood has died, according to a D.C. police spokesman.

The shooting occurred shortly before 9 p.m. at Seventh and O streets NW. Officer Sean Hickman, a police spokesman, said she died at an area hospital.

Police identified her as Tamara Gliss, 31, of Northwest Washington. Authorities were searching for a person seen driving away from the scene on a dirt bike.

The shooting was the latest in a series of violent incidents over the holiday weekend, including three other homicides since Friday. Police have made two arrests in the slayings. At least seven people were wounded by gunfire, according to District police.

About 3:20 a.m. near the Brightwood community in Northwest, police said two people were shot — one in the leg, another in the hand — during a robbery outside an apartment building in the 900 block of Gallatin Street NW. Police said the gunman was driven away in a stolen black sedan that officers tried to pull over a short time later. The driver crashed and several occupants fled, police said.

On a D.C. police Internet community board, authorities said that “it is believed that the suspects may have committed additional robberies” elsewhere in the District. No other details were released.

About 9 p.m. Sunday, police said, Devonte Reed, 20, of Lanham, was fatally shot and another man wounded in a shooting that occurred in the 500 block of 58th Street NE. Police said they arrested a suspect, Jamie Patterson, 26, of Northeast, and charged him with second-degree murder while armed. No other information was provided.

About 1:10 a.m. Saturday, police said Anthony A. Osgood, 29, of Southeast, was shot and killed in the 2300 block of Irving Street SE. Police said a woman also was shot during this incident.

And about 12:20 p.m. Friday, police said Stephen D. Clark, 24, of Bowie, was fatally stabbed in the 1800 block of H Street NE. Police said Tuesday that they arrested the victim’s step-father, Herbert A. Hines, 47, of Northeast and charged him with second-degree murder while armed. Hines was ordered detained Tuesday until a preliminary hearing June 5.

An arrest affidavit filed in D.C. Superior Court on Tuesday says Hines is the victim’s step-father and that two witnesses saw the men engaged in a fist-fight on the street. One witness told police that Clark was trying to defend himself when he was stabbed with a blue-handled knife. Police did not say why the men were arguing.
