UPDATE AUG. 6: Mammoth police seek help finding man missing since July 16; no new leads

The search for a man last seen in Mammoth Lakes and missing since July 16 has turned up no new information, after an investigation by the Mammoth Lakes Police Department and an informal search by some members of the Mono County Search and Rescue team along with other searchers, according to local law enforcement officials.

Greene, 39, an experienced climber and hiker, and a math teacher from  Bethlehem, Pennsylvania, was last known to have been in contact with employees at a car repair shop in Mammoth on July 16, after he dropped off his car for repairs. His phone was then off or out of power, according to Mammoth Lakes Police Detective Doug Hornbeck, speaking to the Mammoth Times on Tuesday.

“We have a record of last call made at 4:33 p.m. on July 16 and that was the last call he made,” he said.
Hornbeck said the police department has done numerous interviews and followed up every tip they have received, and, have gone through Green’s maps and trail guides, hoping to find a clue as to where Greene might have gone after he left his car at the repair shop.

"Greene arrived in Mammoth Lakes on or near June 27 to hike, camp, and conquer peaks in the Eastern Sierra," according to a recent Mammoth Lakes police report.

“He was camping at Shady Rest Campground while his vehicle was being repaired at a local shop. Greene has not returned to Shady Rest Campground or picked up his car from the repair shop," the report states.

“It is believed that he may have gotten a ride from someone to a remote area to hike or climb,” the report said.

There had been some reports on social media that perhaps Greene had torn out a map to take with him on a climb or hike and if so, the missing pages might give a clue to his whereabouts, but Hornbeck said there was nothing missing from Greene’s ledger.

He said the police have also been in touch with Yosemite National Park rangers, in case Greene had headed to the park.

“We have been in contact with our search and rescue, we talked to the Yosemite rangers and they had someone check the summit post for Mt. Lyell, in case he climbed Lyell, but there was no indication he was there,” he said.

Social media had noted that Greene had expressed interest in Mt. Lyell.


Due to the lack of leads as to where Green might have gone, a formal search and rescue effort has not been launched, said Jennifer Hansen, the Mono County Sheriff’s Department public information officer.

However, some of the county’s volunteer search and rescue team has been looking for Greene based on the few tips that might indicate his whereabouts, she said.

“The Mono County Sheriff’s Search and Rescue Team has sent ground teams to search around the Ritter/Banner area,” she said in a news release on Aug. 6.

“As a training mission, a CHP helicopter, along with the assistance of Mono County SAR, did a brief search of the area, including the Minarets. To date, Mr. Greene has not been located. Due to the potential climbing destinations of Mt. Ritter and Mt. Banner being outside of Mono County, the Mono County Sheriff’s Search and Rescue Team has not been officially activated. The SAR team, to actively aid the family and friends of Mr. Greene in their search efforts, has utilized training opportunities to try and locate him.

“The SAR team has verified that no summit register entries have been entered by Mr. Greene at either peak. The SAR team is currently analyzing forest service permits and emailing permit holders to try and gather additional information regarding Mr. Greene’s location.

The Mono County Sheriff’s Office has sent information in reference to this investigation to Madeira County and the Yosemite Search and Rescue Team as their jurisdiction is potentially involved,” she said. “At this time, Mono County SAR has not been formally requested as mutual aid in this search.”

Mr. Greene is 5’11” and weighs approximately 160 pounds. He has short blondish-brown hair and blue eyes. Anyone with any information on Mr. Greene’s whereabouts or other tips for this investigation are encouraged to call Detective Hornbeck at the Mammoth Lakes Police Department at (760) 934-2011 or the Mono County Sheriff’s Office at (760) 932-7549 ext. 7.
