TAKOMA PARK, Md. (NewsNation Now) — A Pentagon Force Protection Agency officer is charged with two counts of second-degree murder and related charges after shooting and killing two people Wednesday while off duty, Takoma Park Police say.

Police say David Hall Dixon of Takoma Park was taken into custody Friday morning without incident. He is also charged with attempted murder and the use of a handgun in the commission of a felony and reckless endangerment.

The shooting occurred early Wednesday morning in the parking lot of the Takoma Overlook Condominium building. Police say Dixon, who was off-duty at the time, said he saw what he believed to be three people attempting to steal a vehicle. Police say when they did not respond to Dixon and attempted to leave the scene in the vehicle, Dixon opened fire, striking two.

Dominique Williams, 32, of Hyattsville and James Lionel Johnson, 38, of District Heights died of their injuries in the hospital Wednesday.

Dixon is also being charged with the attempted murder of Michael Thomas, 36-years-old, the driver of the vehicle that he shot into. Dixon is being held at The Montgomery County Detention Detention without bond.

“Mr. Dixon had no lawful or justifiable reason to shoot and kill Mr. Williams and Mr. Johnson,” officials said at a Friday press conference.

Officials say Dixon is being charged with five criminal charges. Some of those penalties carry 40 years in prison, officials say.

The Takoma Park Chief of Police went on to say people are not encouraged to take action if they witness criminal activity, and to “be a good witness.”
