A motorist was killed early Friday and his passenger was injured in a crash in the Diamond Bar area.
The 21-year-old Diamond Bar man was driving a 1997 BMW M3 south on SR39 near mile marker 28.64 about 12:30 a.m. when he lost control of the vehicle, according to the California Highway Patrol.
According to the CHP’s preliminary investigation, the driver “failed to drive at a safe speed to negotiate the left curvature on the descending roadway and crossed into the northbound lane,” then crashed into a metal post.
Authorities withheld the name of the driver, who died at the scene, pending notification of his relatives. The passenger was taken to a hospital for treatment of moderate injuries, the CHP reported.
Anyone with information on the crash was urged to call the CHP Baldwin Park Area office at 626-338-1164.
