A pedestrian who was struck in a hit-and-run in Aspen Hill, Maryland, on Aug. 11 died Friday, according to Montgomery County police.

Police said around 10 a.m. on Tuesday, 62-year-old Robert Lawrence of Silver Spring, Maryland, got out of his truck in the far right lane of westbound Bel Pre Road.

While he was on the driver’s side of his vehicle, a pickup truck going west on Bel Pre Road hit him and then left the scene.

Lawrence was taken to a hospital in critical condition, where he died from his injuries on Aug. 14, according to police.
