Stuart Emerman, the assistant chief of the Washington Metropolitan Police Department, told reporters that there is no description of any suspect at this point.
“All three individuals have been taken to area hospitals where they are being treated,” Emerman said.
A man and a woman are in stable but critical condition, Emerman said, updating an earlier report from a police source who said two men had been shot. A girl is also being treated for a minor gunshot wound.
The shooting happened on the 2900 block of Van Ness Street Northwest, MPD said.
Emerman said a school in the vicinity of the shooting is still locked down and students are inside. Police are with them and will get the students to a relocation center to be reunited with their parents when they are able to.
Samuel Nicolido, a student who lives near where the shooting took place, told CNN that he had heard about 20 shots.
“It was like five shots and then stopped for like, one minute, and then four more, five more, and then again,” Nicolido said. “I saw cops with shields everywhere and then they were saying — they were telling us to stay at home. Don’t leave. So yeah, it was scary.”
