Matthew Greene, 39 and a math teacher from Bethlehem Pennsylvania, has literally vanished in thin air -- he was last seen on a mountain trek of the high Sierras in California.
Officially Greene was declared missing on July 29, 2013, following a somewhat convoluted and puzzling saga involving his broken down car: Because the vehicle's blown head-gasket wasn't repaired in time for him to leave with friends who'd accompanied him on the journey they all parted ways around July 16th ... and Greene hasn't been seen nor heard from since.
Greene's fellow hikers informed his brother-in-law Ron Minto that he had told them all that day to "go on without me, I'll catch up with you. My car will be ready in a week."
So his friends left him at the Shady Rest Campsite in the Sierra Mountains, the last place Greene allegedly texted from, Minto reports. Thereafter, when they didn't hear from him again, "they started to get concerned."
Whether the experienced climber disappeared from the high Sierras or somewhere in the nearby town of Mammoth Lakes where his Subaru is presently parked is still not known.
Adding to this baffling mystery are rumors that he may have hitchhiked a ride from that community and, because some of his gear was discovered missing, foul play is also now feared.
Greene's long absence and lack of telephone contact is said to be out of the ordinary for him, so anxious family members and friends have set up a Facebook page and launched their own limited ground searches, whilst California authorities continue to insist they don't know where to begin looking yet.
The treacherous terrain of the Sierra Mountains is also hindering the hunt, but recently a hiker discovered a pair of glasses that might belong to the missing man.
Greene has a unique eyeglass prescription his loved ones say, and they're waiting on tests to confirm whether or not these are his. If so, then they will finally have a location from which police can begin investigating.
Admittedly, it's not very much to go one, and a month without word is a long time for someone to be lost in the wilderness -- or worse.
But, "we're still holding out hope. Miracles do happen," Greene's mother Patricia told reporters this week. "Whatever the outcome, we just want him found and brought home."
Matthew Greene is a youthful and athletic 39-year-old Caucasian male, approximately 6-feet tall and 160 pounds, with light brown hair and blue eyes. Anyone with information concerning his disappearance and/or his present whereabouts should call the Mammoth Lakes Police Department or Mono County Sheriff's Office.
