The teenage driver of a Toyota Echo involved in a deadly crash during a police pursuit in Montgomery County has died at an area hospital, officials said Tuesday.

Police said Reynard Osman, 16, of the District died of his injuries Wednesday. He was the third teen to die as a result of the crash.

Two back-seat passengers — cousins Emanuel D. Nelson, 16, and Tyree D. Nelson, 14, both of the 800 block of Longfellow Street NW — were killed in the crash. The front-seat passenger, Reeco Richardson, 18, of the 6000 block of Sligo Mill Road NE, suffered injuries that were not life-threatening.

Police said that in the early morning hours of March 23, the four teenagers were traveling through Montgomery County in a car that a patrol officer found had been reported stolen. Officers began following the Echo, officials said, and were preparing to pull it over along Connecticut Avenue.

But the Echo sped off, according to police, traveling south on Connecticut Avenue before crashing into a tree at Chevy Chase Circle and catching fire.

Police officials said officers were able to pull Osman and Richardson from the car so they could be treated. The officers could not get to Emanuel and Tyree Nelson, who died at the scene, police said.
