Surveillance video shows the gunman entered the NAVSEA building, at 1336 Isaac Hull Ave., with a shotgun, law enforcement officials told News4's Jackie Bensen.NBC national reported a similar story, but notes authorities say Alexis may have taken the guns from an on base safe. If true, someone left that safe open.
He shot a security officer in the head, killing him, and took his 9 mm pistol and a magazine of ammunition. The shooter then continued through the building and seemed to target his victims, who were mostly on the third and fourth floors, Bensen reported.
D.C.’s Metropolitan Police Department and several other law enforcement agencies responded with active shooter teams.
During that response, a MPD officer was shot in the leg. The gunman was then shot by a FBI hostage response team, law enforcement sources told Bensen.
According to what witnesses are telling investigators, by the time the shootings ended, the gunman was seen with a semiautomatic 9 mm pistol and an AR-15 assault rifle. Authorities are investigating whether the gunman took the D.C. police officers’ rifle.
The officials also said Alexis obtained the assault rifle used in the shooting from a gun safe on the naval base. There’s where he may have also obtained a handgun, according to authorities.
One official who spoke to NBC News, however, cautioned there are still outstanding questions about where and how Alexis acquired the weapons used in the massacre.
