Cesar Jimenez Bibiano was 5 years old when he disappeared from Los Angeles, California. The three children were reportedly taken by their non-custodial father, Cesar Bibiano Sr., and their mother.

At the time, Cesar was described as 4 feet 3 inches tall, about 80 pounds, with brown hair and brown eyes. His sisters were 15 and 16 years old. Cesar Bibiano Sr., then 36, was described as a Hispanic male, 5 feet 7 inches tall, about 160 pounds, with black hair and brown eyes. The case has been classified as a family abduction and a felony warrant was issued for Bibiano Sr.

Investigators believe the family may have fled to Mexico and remain in hiding; age-progressed images of the children were released but no confirmed sightings have been reported. If anyone has information about where Cesar or his sisters might be, please come forward.
