Three people died and two suffered major injuries in a crash off of Foothill Road near Pleasanton on Christmas night, according to the California Highway Patrol.
Officers responded at 9:57 p.m. to a report of the crash on Foothill Road just north of Castlewood Drive. They arrived to find a downed power line near the roadway and a Hyundai sedan that had overturned and hit a large tree just east of the road, CHP Officer Tyler Hahn said.
Three people were trapped inside the car and two others had been ejected. The driver and two passengers were pronounced dead at the scene, while two other passengers were taken to a hospital with major injuries, according to Hahn.
KTVU has learned that two of the people killed were brothers and friends. All five occupants of the car were teenagers, CHP said.
Friends of the victims said some of the teens were students at Dublin High School.
Dublin Unified Superintendent Dr. Dave Marken said, "Some of the students involved in the accident, have other students at the high school, students at the middle school. This will certainly rock our community in a very hard way."
Investigators determined the vehicle was heading south on Foothill when, for some reason the driver lost control, the car crossed the northbound lane, hit the power pole and then the tree.
The impact from the crash severed the power pole at the base and upended the pole, causing a transformer to rupture and spill about 20 gallons of mineral oil onto the roadway and dirt shoulder, Hahn said.
CHP officers said nothing indicated alcohol was involved in the collision and they haven't said if speed was a factor.
Anyone with information about the crash is asked to call the Dublin-area CHP office.
