Relatives and friends could not be reached Monday. Police Lt. Robert Alder, the commander of the homicide unit, said detectives were having a difficult time locating Anderson’s permanent home.
“We’re not sure he had a stable address,” Alder said, declining to elaborate on the circumstances of the shooting or a possible motive.
Anderson’s killing was one of three fatal shootings in the District during the weekend. Through Sunday, police statistics show, 56 people have died in homicides this year, compared with 65 at the same time a year ago.
About a half-hour before Anderson was killed, police said, another victim was shot and wounded in the 1600 block of Butler Street SE in Anacostia. Police said the shooting occurred between midnight and 2:30 a.m. Authorities said they were unable to pin down a precise time because the victim declined to cooperate.
Three people were victims of shootings in Southeast that occurred about three hours apart, but police said they do not appear related. One that injured two people was in Anacostia; the other was three miles south, near the Maryland border.
The first attack occurred about 2:13 a.m., when police said they responded to an incident in the 800 block of Barnaby Street SE and found two people who had been shot several times.
Police identified the dead man as 24-year-old Antwan Boseman of Southeast. The other victim survived and was being treated at a hospital.
Alder, from the homicide unit, would not comment on a possible motive but said detectives “are not sure who the intended target was.”
He said it could be the person who was killed, the injured acquaintance or someone else.
About three hours later, an officer responding to a call about a shooting in the 2600 block of Douglas Road SE found 48-year-old Terrence Robinson of Southeast suffering from multiple gunshot wounds.
Police said Robinson was pronounced dead at a hospital.
