California authorities are trying to determine the whereabouts of at least 9 drivers involved in the deadly I-5 tunnel crash.

Ten people injured in the crash were taken to area hospitals, another 10 escaped the flames uninjured, three others, including a 6 year old were killed in the crash. That totals 23 people, but the CHP says 31 vehicles were involved in the crash which leaves at least 9 drivers unaccounted for at this time.

Warren Stanley of the California Highway Patrol, "We have to identify all the vehicles and determine who they belong to and based on registration we can move forward to identify those drivers".

The CHP is hoping the missing drivers will come forward. They think those people might not have driver's licenses or could be illegal immigrants. The tunnel remains closed indefinitely which means more traffic on the southbound lanes of Interstate 5.
