Was Missing Teacher on Apple Store Surveillance Tape?

WNBC reports that Hannah Upp, the 23-year-old school teacher last seen on August 29th (leaving her keys, phone, wallet, and ID in her apartment), "was reportedly spotted checking her e-mail" at the Apple Store on Fifth Avenue. According to WNBC, "members of Upp's family screened the tape and confirmed it was her," and police are also checking to see if Upp did access her e-mail. Police had not suspected Upp was the victim of foul play, because she may have been unhappy with her job. America's Most Wanted is now involved and there's currently a $12,000 reward for information about her whereabouts.
