ONTARIO  (AP) — Five young men riding in the same compact car were killed Monday when the driver lost control, ran a red light, hit a concrete post and came to a stop in a backyard in San Bernardino County.

A coroner’s statement says four of the men died immediately in the pre-dawn rollover crash in Ontario, and another was died at a hospital less than an hour later.

Wreckage from the crash came to rest in the backyard and just a few feet from the bedroom of Alfredo Gonzalez, who said he thought it was an earthquake.

His granddaughter, Jennifer, said the scene in the yard looked “like a bomb that went off.”

“I saw some guy in the car and I was really scared, and I didn’t know what to do and I started crying more,” she told NBC4.

The coroner’s statement said Dylan George, 20, Ervin McKinness, 21, Jonathan Watson, 21, and JaJuan Bennett, 23, were declared dead by police and paramedics at the scene. Marquell Bogan, 23, died at Kaiser Hospital Ontario.

All were from the area in and around Ontario, about 35 miles east of downtown Los Angeles.

Ontario police were investigating what caused the crash.
