A fatal Tesla Cybertruck incident in Piedmont is being investigated by the National Highway and Traffic Safety Administration and California Highway Patrol after three Piedmont high school graduates died and another was hospitalized.

A USC community continued to grieve after it was revealed a student athlete was among the people killed in a fiery Tesla Cybertruck crash on the day before Thanksgiving in Northern California.

The mother of the survivor of Wednesday morning's horrific Tesla Cybertruck crash in the East Bay town of Piedmont that left three young adults from the East Bay community dead on Friday identified her son and the three other victims.

The Piedmont High School graduates were killed when the truck they were driving crashed at Hampton Road between Sea View and King avenues about 3 a.m. Wednesday. The truck caught fire after the crash and one person, who has not been identified, was pulled by a passerby and taken to a hospital.

Over the weekend, the city of Piedmont released the names and brief statements from the families of three 2023 Piedmont High School graduates who died in a fiery Cybertruck crash on the day before Thanksgiving.

The NHTSA often investigates crashes involving electric vehicles with self-driving features. Piedmont officials said last week that speeding is possibly a contributing factor, but they did not say whether the driver assistance features on the Cybertruck were engaged at the time of the crash.

Family and friends are mourning Soren Dixon, Jack Nelson and Krysta Tsukahara, all college students who graduated from Piedmont High School in 2023.
