Roswell police are looking for a driver who they believe witnessed a fatal crash on Ga. 9 on Sunday.

The two-car crash that occurred in front of North Fulton Hospital killed 87-year-old Richard Rosen, of Alpharetta, and police are looking for the driver of a white Ford Mustang GT, possibly of a model year between 2005 and 2009, with tinted windows and a Cobb County license plate.

Roswell police spokeswoman Officer Lisa Holland said the Mustang may have been racing a black BMW northbound on Alpharetta Highway/Ga. 9 from Holcomb Bridge Road/Ga. 140 north of Hembree Road between 12:30 and 12:40 p.m.

Anyone with information on the Mustang or its driver is asked to call Roswell police at 770-640-4100.
