SAN BERNARDINO, Calif., Dec. 30 (UPI) -- Searchers late Monday found the body of an 8-month-old boy, leaving just one victim of the California mudslide still unfound, authorities said.

The discovery brings to 13 the number of victims recovered -- eight of them children, CNN reported Tuesday.

The baby's parents were among the victims of the Christmas Day tragedy, said Chip Patterson, spokesman for San Bernardino County Sheriff's Department.

A 12-year-old boy is still missing.

Patterson said crews concentrated Monday on moving debris in sites where cadaver dogs had made "hits," possibly indicating the presence of a body.

After Tuesday, he said, the search would continue only periodically.

The victims were visiting a church-owned campground when heavy rains sparked a flash flood and mudslide at Old Waterman Canyon, an area of the San Bernardino Mountains. Mountainsides nearby were scorched by wildfires in October and November, which removed vegetation vital to holding soil on the slopes.

One body was found four miles away from the camp, carried by a wall of rushing debris.
