Police said the shooting took place just after 12:30 a.m. local time (Saturday 1630 UTC).
Suspect not yet identified
No arrests were made immediately after the incident.
Worley said that authorities were working to identify a suspect and determine the motive for the attack.
"This is an extensive crime scene, our detectives are going to be here quite a while," he said.
Mayor Brandon Scott urged people to come forward to assist investigators to locate those responsible for the attack.
"This is an absolute tragedy that did not have to happen," Scott said.
"It again highlights the impacts and the need to deal with the over-proliferation of illegal guns on our streets and the ability for those who should not have them to get their hands on them."
