An autopsy on a San Rafael man found dead after hiking in Sequoia National Park showed he died of massive head trauma with fractures and hemorrhaging, a coroner's investigator said Monday.
Thomas Heng, who was with a group of people hiking Mount Langley on July 22, disappeared after going off by himself. After an extensive search by rescuers, his body was found three days later about 300 feet below a precipice.
Jeff Mullenhour, deputy coroner's investigator in Inyo County, said he did not know whether Heng fell directly down from the precipice, or whether he was carried to the spot by an ice chute.
The autopsy revealed no signs of foul play and no sign that a heart attack or other medical emergency preceded the fall, Mullenhour said.
Heng, 31, was an experienced hiker who had lived in San Rafael for about three months.
