Roommates told the New York Post that they last saw Hannah Upp, 23, a week ago. They said they didn't realize anything was amiss until Monday because they knew she had plans to get out of town for Labor Day weekend.

When they looked in her room, her roommates said they found her wallet, keys, pocketbook and cell phone.

Upp, whose parents are Methodist ministers in Salem, Ore., graduated from Bryn Mawr College in Pennsylvania in 2007. She went to New York, where she became a Spanish teacher at Thurgood Marshall Academy in Harlem under the New York University Fellows program, the Post said.

Friends and colleagues said she had been looking forward to the beginning of another year.

"She didn't look troubled," Sandye Johnson, the principal at Marshall, told the Post. "She was happy. She had a glow on her face."
