PIEDMONT, Calif. (KGO) – The sole survivor of a deadly crash involving a Cybertruck in California is in stable condition. The single-vehicle crash killed three college students on Nov. 27 who were home for Thanksgiving.

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.

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 stunning crash in Piedmont that killed three college students, leaving a third with severe injuries, has triggered deep suspicion of the vehicle involved: a Tesla Cybertruck, the electric pickup with a space-age look — and a history of engineering mishaps.

While the cause of the deadly crash in Piedmont is under investigation, firefighters are finding themselves in tricky situations with electric car fires. KRON4 spoke with fire officials on some of the challenges they have faced in putting out these fires.
