Detectives say they're trying to determine the identity of a man caught in a 19-second clip of video, who they say may be connected to the May 1 stabbing of Dwayne Edward Brisbon. Brisbon was stabbed and killed in the 400 block of Florida Avenue at about 2:15 that morning.

Police say that Brisbon, an Upper Marlboro resident and a CT Scan technologist at MedStar Washington Hospital Center, was found inside a vehicle that had crashed with stab wounds to the neck. Police said at the time of the stabbing that Brisbon was driving in the area that early morning and got into an argument with another person, who then stabbed him.

Brisbon then attempted to drive away when he crashed about a block from where he was stabbed, police say. He was pronounced dead at an area hospital.

Anyone with information in the stabbing is urged to call MPD detectives at (202) 727-9099. A reward of up to $25,000 is being offered in the case.
