A search was begun on Tuesday for Tom Heng, 31, who took a day hike to Mount Langley on Sunday but failed to return as planned. Heng was last seen that day on Mount Langley around 1 p.m. His hiking route was expected to run from the Cottonwood Lakes trailhead through New Army Pass to the summit of Mount Langley, with a return to the same trailhead. Participating in the operation were personnel from Sequoia-Kings Canyon, Manzanar and Yosemite, the China Lake Mountain Rescue Group, Friends of Yosemite Search and Rescue (“YODOGS”), Inyo National Forest, Montrose Search and Rescue, Sierra Madre Search and Rescue, and the Tulare County Sheriff’s Department. Heng’s body was found on Wednesday. The cause of death has not yet been determined; an investigation is underway.
