A crash involving an SUV and a box truck left two people dead and a third injured in Irvine on Thursday morning, police said.
Officers and personnel from the Orange County Fire Authority responded to the area of Oak Canyon and Valley Oak Drive to a report of a crash shortly after 10 a.m., according to an Irvine Police Department news release.
A witness told KTLA the SUV was stopped at a stop sign before making a left turn onto Oak Canyon, pulling out in front of the box truck, which then slammed into the vehicle.
The truck had the right of way, as there was no stop sign in the area where it was driving, according to the witness, who did not want to be identified.
Two people in the SUV died at the scene, while a third occupant was transported to a hospital in unknown condition.
Authorities have not released the names, ages or genders of any of the occupants, but the witness described them as "elderly" women.
The truck driver, who not injured, is cooperating with investigators, according to police.
No one has been arrested or cited in the crash, the release stated.
A stretch of Oak Canyon has been closed between San Canyon Avenue and Post until further notice as police investigate the double fatal crash.
No additional information was immediately available.
