COSTA MESA, Calif.—A car-to-car shooting in Diamond Bar left one person dead and another person hospitalized with a leg wound, with the victims found miles away in Costa Mesa, authorities said Aug. 2.

The California Highway Patrol’s Santa Ana office received a 911 call shortly after 11 p.m. Tuesday regarding a freeway shooting near the southbound Orange (57) Freeway and the westbound Pomona (60) Freeway.

The white sedan containing the victims later stopped near Church Street and Walnut Street in Costa Mesa, where officers from the Costa Mesa Police Department found the victims inside the vehicle with gunshot wounds, according to multiple media reports.

One victim was pronounced dead at the scene and the second victim was taken to a hospital with a gunshot wound to the leg, Fox11 reported.

Another car was struck by gunfire at the Diamond Bar location, but apparently, no one was injured in that shooting. The incidents are believed to be related, but the motive for the gunfire was not immediately clear.

The highway patrol closed the freeway transition road for several hours to investigate the shooting.
