Passenger Antonio Del Castillo, 17, of Fairfield had moderate injuries was taken to the same hospital by ambulance.

The CHP reported a caravan of vehicles was driving south on Highway 121 at about 1:30 p.m. when one of the cars, a 1994 Honda Civic, went off the road and down an embankment about one mile south of Circle Oaks Drive.

The car overturned and landed on its roof in a creek.

Friends in the other vehicles stopped along the highway and went down the embankment in an attempt to help the victims, the CHP said.

Emergency crews had to free the three from the crushed car.
