A race car at the Marysville Raceway Park in Yuba County lost control and killed two people on pit row Saturday night, the Yuba County Sheriff's Department reported.
A 68-year-old man and a 14-year-old boy died after being hit by the spint car. They were both reportedly part of the crew of one of the teams in the race.
There were no other reported injuries.
Marysville is about 40 miles north of Sacramento.
A venue promoter told the Appeal-Democrat the car lost control, left the track and crashed into pit row. This happened during a warm up lap prior to the actual race. The car was reportedly going 90 mph and did not make a proper turn.
Track officials said on the Facebook page: "Our thoughts and deepest prayers go out to everyone. Out of respect we will not elaborate on details. We ask everyone to respect each other and the families."
Marysville Raceway Park was hosting Round 1 of the Hoosier Tire California Sprint Car Civil War Series this weekend.
The race was canceled after the crash.
The race is described as the "newest rendition of California's premier traveling body for winged 360 sprint cars is sure to be action packed with the best of west racing wheel to wheel and wing to wing throughout the golden state."
Sprint cars are below NASCAR and are small, high-powered cars that normally race on short dirt tracks
