Authorities continued to search late Monday for two Costa Mesa hikers who called for help from a cellphone before their battery died.
About 8:25 p.m. Sunday, Nicholas Cendoya, 19, and Kyndall Jack, 18, notified authorities that they were lost while hiking in Trabuco Canyon, according to the Orange County Sheriff's Department.
The two thought they were about a mile from their vehicle, authorities said. Deputies searched for the man and woman on foot but were unable to find them.
Authorities continued the search using bloodhounds and air support, according to the Sheriff's Department.
The Sheriff's Department asked that anyone with information about the whereabouts of the two call (714) 647-7000.
