(TAKOMA PARK, Md.) — David Hall Dixon, a Pentagon Force Protection Agency police officer who was off duty at the time of a fatal shooting in Maryland, has been charged with second-degree murder for allegedly killing two people, Takoma Park police said Friday.

Those killed were identified by the Takoma Park police as Dominique Williams, 32, and James Lionel Johnson, 38.

The shooting took place in a parking lot early Wednesday, according to police.

Shortly after 5 a.m. Wednesday, Takoma Park police responded to reports of shots fired in the parking lot area of the Takoma Overlook Condominiums, according to a department news release issued Wednesday.

An off-duty Pentagon Force Protection Agency officer approached the Takoma Park police and said he had seen what he thought was a car break-in and “engaged the suspects who failed to follow his direction,” according to the Wednesday release.

When the suspects tried to “flee” in a vehicle, the Pentagon Force Protection Agency officer said he “discharged his service weapon,” Takoma Park police said then.

The two men shot were taken to the hospital and died there, police said.

The Takoma Park Police Department has scheduled a news conference for 2 p.m. Friday.
