AZUSA, Calif. (KABC) -- The driver of a car that plunged about 50 feet over the side of the road and into a ravine in Azusa may have been drinking, police said Monday.

On Saturday, Caliz drove off Highway 39 about a 1/2 mile north of the U.S. Forestry information booth. The car flipped over and ultimately killed his two young children -- Christopher Caliz Martinez, 8, and Andrea Caliz Martinez, 12.
Caliz, who is unlicensed, his wife 32-year-old Marbella Martinez and his 13-year-old daughter survived the crash.
Witnesses told police that the vehicle was speeding. Skid marks were found in the road.
A toxicology test was still pending. No arrests were made.
