It was reported to the police at 8:57 p.m. in the 4800 block of Alabama Avenue SE, Carew said. A woman was also shot in that incident, he said.
A second double shooting was reported about 15 minutes later in the 100 block of Darrington Street SW, Carew said. At 9:15 p.m. another shooting was reported, in the 1400 block of Rhode Island Avenue NE.
No obvious connection between the shootings was apparent late Friday; it was unclear why they all happened in so brief a period. The sites had little in common geographically, with none particularly close to the others.
However, Darrington Street is about a mile or two west of the Washington Highlands area where four people were killed within three days this week; the most recent killing was earlier Friday.
Darrington is a relatively short residential street. The sites of the other two Friday night double shootings are more prominent thoroughfares.
