NYC Teacher Hannah Upp Still Missing

Some more info about 23-year-old missing school teacher, Hannah Upp, who works at Thurgood Marshall Academy in Harlem. WNBC reports police want the public's help in finding her. A source says cops "don't suspect foul play" since "she may have been unhappy in her job," though many close to her say she was looking forward to the school year. Her brother told ABC that she "isn't some naive small-town girl off to the big city thinking the world is made of cotton candy and gumdrops." The NY Post reports friends have "posted fliers throughout Times Square, where she last used her ATM card at a movie theater." And on the Facebook page they created, they say Upp enjoys running in two parks--presumably Jackie Robinson and St. Nicholas, which are both near her apartment (where she left her keys, wallet, ID and other belongings).
