A US Navy medic shot and critically wounded two people at a Maryland business park, then fled to a nearby military base where he was shot and killed, police and navy officials said.
The gunman entered a business at the Riverside Tech Park, causing people inside to flee, but it was unclear if the shooting took place inside or outside, Frederick Police Chief Jason Lando said.
After the shooting, the man drove about 10 minutes to Fort Detrick, where he was shot by police who followed him onto the base, Mr Lando said.
The Navy did not release further details.
Mr Lando said: “We have two different scenes.
“All I can tell you is that we have confirmed there is only one shooter.
“The public is no longer at risk.
“Everyone is safe.”
