A 4-year-old boy died and four people were injured in a head-on crash in Napa County on Sunday afternoon, according to the California Highway Patrol.
Cindy Pawlcyn, a Napa-area restaurant owner, was one of the people injured in the collision. The 58-year-old woman suffered "moderate" injuries after the Lexus SUV in which she was a passenger in was hit by a Chevrolet Equinox on Highway 121, the Napa Valley Register reported.
The Carneros-area crash also injured the boy's 27-year-old mother and other passengers in the Lexus.
Napa-resident Flavio Castellanos, 23, was driving the Chevrolet. Castellanos suffered major injuries and was taken to the Queen of the Valley Hospital in Napa.
The driver of the Lexus, Pawlcyn's husband, John Watanabe, 66, of St. Helena, was also injured.
It's not known what caused the Chevrolet to veer across the double-yellow line in front of the Lexus. CHP officers said the two vehicles hit almost "license plate to front license plate," the newspaper reported.
The boy was in a booster seat, according to the California Highway Patrol. All other passengers were using seat belts. Neither drugs nor alcohol are considered factors.
