One person is in critical condition after a US Navy medic shot two people on Tuesday near a military base in Frederick, Maryland.
Police received an alert about a shooter in an office park in Frederick, which is about an hour's drive from Washington.
The gunman, who was later identified as Fantahun Girma Woldesenbet, 38, fled to nearby Fort Detrick military base.
According to Frederick Police Chief Jason Lando, base personnel on the base shot and killed the gunman.
Woldesenbet was a third-class Navy corpsman, or medic, authorities confirmed Tuesday afternoon.
The two people the gunman shot were taken to hospital and one remains in critical condition.
Chief Lando said police are working to find a possible motive behind the shooting and Brig Gen Michael Talley of Fort Detrick said that investigators w were looking into whether the gunman knew the two people he shot.
“We don’t want to compromise any aspect of the investigation," Brig Gen Talley said, declining to comment further.
The local official response was quick.
“Our emergency responders are well trained for these types of situations and the fast response of our military police enabled us to contain this threat quickly," said Commander Dexter Nunnally of US Army Garrison Fort Detrick.
The US Navy tweeted they will provide updates when possible.
“The US Navy can confirm there was an active shooter incident at Fort Detrick, Maryland, involving US Navy sailors. The shooter, a Navy hospital corpsman, is deceased. We will continue to update with additional details as the situation evolves."
Another shooting involving a member of the US military occurred in 2009 at Fort Hood, Texas, when a US Army major and psychiatrist conducted the largest mass shooting on a US military base, killing 13 and injuring more than 30.
