Updated: D.C. police now report five slayings in the four-day period.

D.C. police have been investigating the violent deaths of five people, including three women, in what authorities describe as apparently unrelated homicides across the District.

Police said the women — ages 31, 53 and 64 — were found dead in recent days in what appear to be separate incidents miles apart. One was shot, another asphyxiated and the third stabbed. It is not clear when they were killed and no arrests have been made. Police declined to discuss possible motives.

In addition, two men were fatally shot over the weekend. An arrest was made in one of those cases.

The slayings kept police busy on the first weekend this year in which officers across the city were called in for patrol duty over 48 hours as part of a controversial policy called All Hands on Deck, a way to bolster the force at times when crime tends to surge. The slayings bring the District’s homicide count to 59 for this year, compared with 38 at this time last year.

The most recent fatal shooting occurred about 12:30 a.m. Monday in the 1900 block of H Street NE, in Carver-Langston. Officer Araz Alali, a police spokesman, said the man was shot multiple times and pronounced dead at the scene. He was identified as Darryl Delonta Jacobs, 23, of Northeast.

About 4:15 a.m. Sunday, police said a woman was found fatally stabbed in her apartment in the 5200 block of Queens Stroll Place SE. Eboni Domally, 31, was pronounced dead at the scene.

About 2:45 a.m. Saturday, Talbert Mitchell Bright, 48, was shot and killed near Second Street and Massachusetts Avenue NW, near Union Station and one of the District’s largest homeless shelters.

Police said Bright had no permanent address. On Sunday, Alali said, police arrested James Johnson, 30, and charged him with second-degree murder while armed in connection with Bright’s death. Police said Johnson also lacks a permanent address. A motive was not divulged.

On Friday, police said the body of Mary Anne Thomas, 53, was found in her apartment in the 1200 block of Howison Place SW, near Nationals Park. Police said officers went to the apartment after getting a call from someone concerned about her welfare. Police said she had been shot.

Also, about 8:30 p.m. Friday, police found the body of a woman inside a residence in the 4100 block of Gault Place NE. Alali said an autopsy revealed on Sunday that the woman had been asphyxiated. She was identified as Barbara Moore, 64.
