Four people were shot, one fatally, in three separate shootings in the District Monday night, a spurt of violence D.C. police said occurred within a 20 minute time span in Southeast and Northeast.

Police had few details about the shootings Tuesday morning. On Tuesday afternoon, they identified the man killed as Jerry Williams, 22, of Northeast.

Authorities said the wounded included two teens shot in a drive-by and another teenager shot as he tried to escape a robbery attempt involving a pack of youths and young men on bicycles.

The last shooting occurred about 11:40 p.m. in the 4700 block of Brooks St NE, north of the Benning Road Metro stop. Officer Anthony Clay, a D.C. police spokesman, saud Williams was shot in the chest and died at a hospital.

Clay was not able to say whether the shooting occurred inside a house or on the street, nor could he elaborate on a motive.

About 11:30 p.m. in the 2700 block of Naylor Road SE, police said 10 males between the ages of 15 and 25, all riding bicycles, approached six juveniles standing on a corner near the Good Hope Marketplace.

Clay said one of the bicyclists said, “Give it up,” and then shot at a 16-year-old who tried to run. The teen was wounded in the left shoulder, police said. Authorities did not say if anything was taken.

Two teens, ages 16 and 19, were shot about 11:20 p.m. in the 4800 block of Alabama Ave SE, according to police. Clay said a gunman in a silver four-door vehicle opened fire outside an apartment building. He said the 19-year-old was shot in the leg and the 16-year-old suffered a graze wound to a leg.

The victims were treated at a hospital. Police said they’ve made no arrest in any of the shootings.

Earlier Monday, about 3:20 p.m., police responded to another shooting, in the 2100 block of I St. NE. Police said a man shot a woman in the foot. Clay said detectives have not made an arrest.
