Reward Offered for Missing Teacher

Upp's outgoing nature makes her disappearance even more confusing to her friends and family.

"I refuse to believe that she would run away without taking [her purse or clothes] with her. There's not clothing missing that would suggest she had packed for a trip," Wood said. "None of it makes any sense, which is so weird."

Despite the confusion, Upp's friends and family remain determined to find their friend.

"What we're trying to do is get the word out to as many people as possible to see if anyone can provide a missing piece," Wood said.
