Prince George’s County police are investigating a shooting that left two men dead in Fort Washington Friday night.

Graham Edmonson Hayes II, 45, and John Jay Bromwich, 47, were found shortly after 10:30 p.m. in the 10900 block of Indian Head Highway. Both men, who had been shot, were pronounced dead at the scene.

Police believe that Bromwich shot Hayes before turning the gun on himself and taking his own life. Police said the two men worked together at the location of the incident, but did not provide any additional details.

A motive has not yet been established in the case, and the investigation is ongoing.
