The search for a young man and woman who vanished in Orange County's Cleveland National Forest was to resume Wednesday morning, with the effort growing more urgent with every hour since the teens were last heard from on Sunday night.
Parents of Nicholas Cendoya, 19, and Kyndall Jack, 18, hoped for a sign of their kids somewhere in the wooded area as experts and volunteers continued the hunt, said Lt. Erin Guidice of the Orange County Sheriff's Department.
Searchers were concentrating on an area of the Holy Jim Trail where a bloodhound picked up a scent during an overnight search, Guidice said.
The Costa Mesa teens called authorities Sunday night saying they were lost about a mile from their car in Holy Jim Canyon, but their cell phone lost power soon afterward.
The rocky, tree-shaded dirt trail leads to a waterfall on a 2.8-mile round trip and is popular with day hikers. Its difficulty is listed as moderate to serious on a U.S. Forest Service website. However, the lost hikers "did not keep to the trail," Guidice said.
The area has heavy brush and a creek running through it, she said. Temperatures were moderate Friday, following an overnight low in the 50s.
The area is in a section of the national forest in the Santa Ana Mountains, which lie along the border of Orange and Riverside counties southeast of Los Angeles. The trail ranges in elevation from about 2,000 feet to about 4,000 feet.
