A young boy was hit and killed by a vehicle backing out of his neighbor's driveway in Yorba Linda on Wednesday, officials said.
The incident was reported around 4:50 p.m. in the 4000 block of Casa Oro, on the west side of town, Orange County Sheriff's Lt. Cory Martino said.
The child, described by sheriff's officials as nearly 2 years old, was taken to the Children's Hospital of O.C., where he was pronounced dead.
The boy's parents were at the scene and accompanied him to the hospital, according to Martino.
The driver involved remained at the scene and was cooperating with investigators, the lieutenant said. Authorities were looking into whether the man was possibly intoxicated.
"We don't have information that impairment was a factor in this accident," Martino told KTLA, "but again, we are investigating this."
Video from the scene showed a large, white pickup truck that appeared to be lifted being processed by detectives as evidence.
An accident reconstruction team was at the scene Wednesday night working to determine what led up to the fatal incident. No further details were available.
