NEW: Rescuers find Kyndall Jack, 18, in Trabuco Canyon Her companion was found alive Wednesday night The two got lost while hiking Sunday night, authorities say (CNN) -- A hiker who had been missing for more than three days in a heavily wooded area in California has been found alive, Orange County Sheriff's Department spokesman Lt. Steve Gil told CNN. The condition of Kyndall Jack, 18, is "unknown," he said. Jack's companion, Nicholas Cendoya, 19, was recovering in a hospital after being rescued Wednesday night in Trabuco Canyon, CNN affiliate KTLA reported. Rescuers on Thursday used three airships and dogs to search in that area for Jack. Cendoya's rescue gave authorities hope that Jack also would be found. Cendoya was found in an area of very dense brush, KTLA said. The search began Sunday night after the Costa Mesa, California, teens called authorities from a cellphone, saying they were lost, KTLA reported. They had parked their car and gone hiking but couldn't find their way back, they said. Their phone battery died before authorities locate them through its signals, KTLA said. Cendoya was found about a half mile from the car.
