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

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 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.
