County officials have identified the second victim in Sunday morning's fiery crash that closed a portion of the roadway.

The Contra Costa County Coroner's Office identified Concord resident Brandon Rosevear, 18, as the driver of the Nissan Maxima that struck another vehicle while headed southbound on Interstate 680 near the Crow Canyon Road exit. On Monday, officials identified San Ramon resident Merhrdad "Rex" Emami, 46, as the passenger in the silver BMW that was struck by Rosevar.

The collision was reported just after 1:20 a.m. at the Crow Canyon Road off-ramp, according to the CHP. The female driver of the BMW was transported to the hospital with major injuries; her identity has not been released.

While the cause of the crash is still under investigation, CHP officials said the collision caused both cars to spin out of control. Rosevear's Nissan spun into the construction area, striking a forklift on the driver's side before catching on fire with the driver still inside; Rosevear died in the accident and was severely burned said Deputy Tim Biggs.

Construction sites normally have Highway Patrol officers on site as well as Caltrans supervisors, said CHP Officer Steve Creel. Creel said the collision was most likely due to a speed differential between the vehicles and not construction, as traffic had already been narrowed to one lane.
