Family and friends of the Bethlehem man who disappeared on a hiking trip in California came together to raise money for the extensive search effort.
A special fundraising breakfast was held Sunday morning at the Applebee's in Bethlehem.
The money raised will go to help in the search of Matthew Greene.
He's a math teacher at Nazareth Area High School, and he hasn't been heard from since July 16.
Friends recently went to California to help scour some of the trails... but not many clues have been found.
Greene's sister says the family is just seeking closure.
"We have so many questions as to what to could have happened to him," Tiffany Mint said. "I mean nothing adds up as to what we know with Matt. He's usually safe.. cautious and careful. We just don't know.
"Every day, when we wake up, he's our first thought. When we go to bed he's our last thought. I not quite sure how to turn it off... all that speculating how to figure it out."
Greene was camping in the Mammoth Lakes area in the heart of the Sierra Nevada mountain range when he vanished.
