A combination armed robbery, fatal pedestrian accident was reported to Prince George’s County police just after midnight.
Several people in a car were approached by at least two men armed with guns in Fairmont Heights, Maryland.
The gunmen, who were wearing masks, ordered the people inside the car to get out and lie on the ground.
One of the passengers did just that, but police say the driver, whom they described as “startled”, accidentally ran over the passenger on the ground and killed him.
The suspects then fled the scene and, at last report, were still on the loose.
Police have not said if anything was taken from the victims.
