A race car struck and killed a teenage boy and a man at a northern California speedway during warm-up laps on Saturday, and authorities are investigating what led to the fatal mishap, a sheriff's official said.
The 14-year-old boy and 68-year-old man were standing in the maintenance pit area alongside the dirt track of a sprint-car race at Marysville Raceway Park, about 100 miles (160 kilometers) northeast of San Francisco, said Yuba County Sheriff's Captain Ron Johnson.
"One of the cars left the track and drove into the pit area," Johnson said, adding that it remained unclear whether the driver exited the track because he was done with his warm-up or lost control of his car due to mechanical problems.
The car ended up striking the teenager and the man who were "standing basically next to each other," Johnson said.
The man died at the scene and the teenager was pronounced dead at a local hospital, Johnson said. Their names have not been released.
