Speed, intoxication caused deadly Cybertruck crash that killed 3 Piedmont High grads: CHP

PIEDMONT, Calif. (KGO) -- The California Highway Patrol released its preliminary report Friday evening on the deadly Cybertruck crash in Piedmont that killed three college students over Thanksgiving break last year.

Authorities have determined that speed and intoxication are to blame for the crash that left three Piedmont High School graduates dead and another injured.

Soren Dixon, Krysta Tsukahara and Jack Nelson died in that Nov. 27 crash when their Cybertruck "jumped the curb, struck a cement wall, and then wedged in between the wall and a tree" and erupted in flames near Hampton Road and King Avenue.

According to the CHP's report, Dixon, who was the driver, failed to navigate a turn on Hampton Road due to a high rate of speed and his level of intoxication combined with his drug impairment.

As for the other victim, Jordan Miller, who was injured in the crash, a friend who was driving behind them pulled up to the scene and was able to pull him from the Cybertruck.

According to the report, that friend went back to try and rescue Tsukahara by grabbing her arm and trying to pull her through the same window but the flames overtook the truck. They told police they desperately tried to break another window but once they finally gained access to the car the fire had made its way throughout the entire vehicle.

Earlier this month, the Alameda County Coroner's Bureau released toxicology reports which showed that Dixon had a blood alcohol level of .195% and also had methamphetamine in his system.

The autopsy report determined the cause of death for all three victims was asphyxia and smoke inhalation and ruled their deaths an accident.

CHP's Multi-Disciplinary Accident Investigation Team (MAIT) has been involved with this investigation. The MAIT investigation remains ongoing.
