The collision happened about 12:20 a.m., when a 2006 Cadillac STS hit a tree near the intersection of Stanford Drive and Hastings Avenue, near Setterquist Park. The driver of the Cadillac was trying to make a left turn onto Hastings from Stanford but lost control and struck a tree, according to Vallejo police. The driver suffered critical injuries and was taken to a hospital, where he died. His name was not released. A woman who was a passenger in the car wasn’t injured, police said. Vallejo police are investigating to determine the cause. Alcohol is believed to be a factor, and toxicology results are pending. This collision is the city’s seventh fatal crash this year.
