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.

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.
