It's a picture that gave new hope to Matthew Greene's family and friends. A hiker in California found glasses that looked like a pair belonging to Greene, who has been missing for more than a month.
"Those glasses are not Matthew's," said Detective Doug Hornbeck, of the Mammoth Lakes Police Department.
Hornbeck said the glasses were sent to an optometrist in Bishop, Calif., about 40 miles south of Mammoth Lakes, who determined they weren't a match.
Greene, 39, a math teacher with the Nazareth Area School District, was last heard from on July 16.
The teacher, who family members describe as an avid hiker, rock and ice climber, arrived in Mammoth Lakes on June 27. Police say Greene was staying at Shady Rest Campground after his car broke down.
Authorities were notified after Greene never came back for his car and never returned to the campground.
"Our problem is we just don't know where Matthew went to, where he hiked," said Detective Hornbeck, who says they haven't been able to narrow down the search area.
"Everyone backpacking right now and hiking is aware of Matthew Greene," said Detective Hornbeck, who says they continue to receive tip calls daily.
