HEMET, Calif. (AP) — Eight Southern California teens had just finished one of the final days of their school year when they met with a speeding pickup truck as they walked across the street.

A fellow student and his twin brother were in the 1994 Ford Ranger that plowed into a crowded crosswalk Wednesday and sent the students to the hospital, three of them in critical condition.

“The kids were in the crosswalk doing everything right,” said Emily Shaw, principal at Hemet High School.

Nine people were hit: six female students, two male students and a 60-year-old woman whose ties to the school were not clear.

The truck’s driver, 18-yearold junior Daniel Carrillo, was not under the influence of drugs or alcohol, California Highway Patrol Officer Darren Meyer said.

Authorities gave no indication of how or why he may have shot through a red light and hit the pedestrians who were headed toward the student parking lot and school football stadium.

Carrillo, in the truck with twin David and a 16-year-old friend, immediately got out to help, Meyer said.

Three of the victims, all students, were in critical condition, and six more were taken to hospitals with minor injuries, CHP and county fire officials said.

The collision came with just two days left in the school year and on the last day of classes for graduating seniors, none of whom were among the victims.

Witnesses told the Riverside Press-Enterprise that the driver, whose truck was modified for off-road use, seemed to accelerate into the intersection, running a red light and hitting the pedestrians.
