An 8-year-old boy was killed, and two others were seriously injured after they were hit by a van while they were headed to an elementary school in Oxnard, California, on Monday morning, Sept. 30.

Around 7:40 a.m., officers responded to Ramona Elementary School on Cooper Road and found a little boy in cardiac arrest, ABC7 reported.

A teacher and campus supervisor attempted to provide aid to the three victims, police said.

The boy was transported to the hospital where he was pronounced dead. The woman and her 9-year-old daughter were also taken to Ventura County Medical Center in stable condition and expected to survive.

The van’s driver, a 17-year-old girl, hit them while traveling eastbound on Cooper Road. She had just dropped her sister’s children at Ramona Elementary, according to police.

The teen driver, who was distraught after the crash, stayed at the scene and is cooperating with investigators, Cmdr. Luis McArthur said.

The girl told investigators the sun was in her eyes and “she simply didn’t see them” as the woman and the two children were in a crosswalk, McArthur said.

All three victims were hit while in the crosswalk. There was no stop sign at the intersection, and it is not patrolled by a crossing guard.

The authorities did not believe alcohol or drugs played a factor in the incident.

“There’s no evidence at this point that this is anything beyond a tragic accident,” McArthur said.

The incident is under investigation and no further details have been released.

The boy was the woman’s neighbor and she routinely walked him to school along with her daughter when the boy’s parents go to work, the commander said.

Both children attended Cesar Chavez Elementary School, which is down the street from where the incident occurred.
