Inyo County law enforcement is conducting a search of the Buttermilk area for a man last seen in July.
The man, 64-year-old Richard John Malten of Oregon House, Calif., was reported missing earlier this week, according to Inyo Sheriffâ€™s Public Information Officer Carma Roper, leading investigators to his abandoned vehicle along McGee Creek west of Bishop.
That vehicle, so far, is the only lead investigators have on Maltenâ€™s whereabouts.
According to U.S. Forest Service Public Information Officer Nancy Upham, Forest Service personnel first took note of Maltenâ€™s Jeep in July, but at that time he was apparently camping near McGee Creek.
Upham said that it is unclear when Malten stopped using his vehicle, but Forest Service personnel did recently notice that the Jeep was abandoned â€“ in the same spot Malten was thought to be camping near McGee Creek.
Shortly after that observation, the Inyo County Sheriffâ€™s Department received a missing persons report for Malten filed by his ex-wife, Roper said.
Malten is described as five foot, eight inches tall, 144 pounds with curly brown hair and brown eyes.
Investigators are asking anyone who has seen or heard from Malten over the past four months to notify the Sheriffâ€™s Department at (760) 878-0383.
