WASHINGTON, D.C. (BNO NEWS) — At least one person was killed and up to nine others were injured after a mass shooting in Washington, D.C. on Tuesday evening, officials said.

The D.C. Metropolitan Police Department said officers responded to the 4000 block of South Capitol Street SE after a 911 call came in at 7.27 p.m. local time. “When the lader truck from the closest station, that had a paramedic on board, arrived at the scene, they found a very chaotic situation,” a spokesman for the DC Fire and Emergency Medical Services said. “Numerous victims, all aparent gunshot wounds. Additional resources, EMS crews and others, were called to the scene.”

The department confirmed one person had died, while five others suffered from life-threatening gunshot wounds. Three others sustained moderate injuries. All victims, except one teen, were in their 20s and 30s.

A tenth victim was also found several blocks away, and is believed to be related to the shootings at South Capitol Street. Authorities say an adult male was shot around the same time as the first shooting, and was airlifted to hospital.

“It’s a pretty large scene,” a police spokesman said, who had no information about possible suspects or about the circumstances of the shooting. “Details are still coming in,” he said.

NBC Washington reported that an AK47-type weapon was reportedly thrown from a green Sedan that police chased through parts of D.C. and across the Prince George’s County line. More information was not immediately available.

Another wounded person, a possible tenth victim, was found nearby the shooting scene, and was transported by helicopter to a local trauma center. “It may or may not be related,” a DC Fire & EMS spokesman said.
