A visiting Mexican family was involved in a head-on collision on a California highway that left four dead and six injured, police said.
Two vehicles, which appeared to be a large SUV and a mid-size sedan, crashed on Highway 12 in Rio Vista shortly after 8 p.m., Solano County Sheriff’s Office Sgt. Rex Hawkins told NBC News.
There were fatalities in the two vehicles involved in the crash, he said.
All four people who died were pronounced dead at the scene, while the six injured were taken to hospital, the Rio Vista Fire Department, which responded to the incident, said in a statement.
Although authorities have not released the names and ages of those killed or the conditions of most of those injured, Rio Vista Police Chief Jon Mazer told NBC Bay Area that one person will “reasonably well”.
Rio Vista is more than 80 km northeast of Oakland.
“Just speaking of the one person in the hospital, I know they were on a family vacation from Mexico,” he said. “The other car, I would say are youngsters. I don’t know their age, but I would estimate they are 20-year-olds.
Firefighters have warned that traffic in the area will be affected by the investigation into the crash.
It also said its service for non-emergency calls could potentially be slightly delayed due to efforts to help transport patients to hospitals.
The cause of the accident remains under investigation.
