The 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 that Reynard Osman, 16, of an unconfirmed address in the District, died of his injuries last Wednesday about 5:40 p.m., the third teen to die as a result of the crash.

Two rear-seat passengers — cousins Emanuel D. Nelson, 16, and Tyree D. Nelson, 14, both of the 800 block of Longfellow Street N — 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 in a car that a patrol officer found to be reported stolen. Officers began pursuing the car to make a felony stop. But the Echo sped off, according to police, traveling south on Connecticut Avenue before crashing into a tree at Chevy Chase Circle and bursting into flames.
