Sheriff's officials tell the Orange County Register the names of the teens killed in the Newport Beach wreck were expected to be released Tuesday.
Newport Beach police spokeswoman Kathy Lowe says the Infiniti sedan they were in veered off a road Monday evening and hit a tree. The vehicle split in half and caught fire.
Lowe says four people were ejected from the car and died immediately. A fifth was partially ejected and was later declared dead at a hospital.
The cause of the crash wasn't immediately clear.
No other vehicles were involved.
