Two people were killed when they were struck by a sport utility vehicle Sunday in a San Bernardino County church parking lot.
The crash happened in the parking lot of East Sarang Community Church located at 5540 Schaefer Avenue in Chino.
The driver was backing up out of a parking stall at high speed, hit the six victims and then accelerated forward, crashing into a wall. Two women were killed and four others suffered non-life threatening injuries, according to the Chino Police Department.
The victims were attending an event at the church, but were not members of the congregation.

The crash happened just after 7 p.m. as a reception let out. All of the victims were standing on the sidewalk when they were hit.
The senior male driver and his female passenger were also taken to the hospital with non-life threatening injuries.
The crash was not believed to be "terrorism-related," police said. Police do not believe the crash was intentional, but it was not immediately clear what caused the crash.
"We don't know what his coherentness was," said Lt. Kevin Mensen of the Chino Police Department. "We don't know what caused that, whether his age or anything else."
The names of those involved have not yet been released.
