Investigators worked Monday to determine what caused a pickup truck to crash into two vehicles parked along a Chula Vista roadway, killing the driver and injuring someone working on one of the cars.

Witnesses told police officers the driver of a speeding Toyota pickup truck apparently lost control on eastbound C Street and went airborne before rolling over and striking two parked vehicles near Fourth Avenue around 8:30 p.m. Sunday, according to a Chula Vista Police statement.

The Toyota’s driver was ejected and died at the scene, police said.

A person who had been working beneath one of the parked vehicles when it was struck was taken to a hospital with potentially serious injuries, police said.
