A family is desperately searching for their teenage daughter who vanished from an Occupy Wall Street cross-country junket 17 days ago.

Stevie Bates, 19, borrowed a cellphone April 27 to call her mother, Vivian, of Yonkers, while on a Greyhound bus layover in Pittsburgh. “She said that she would be arriving at 5:40 a.m. in New York” the next day, said her worried mom.

Video footage reveals the 5-foot-6, 120-pound teen with dyed-blond dreads boarded the bus in Pittsburgh. It was to stop next in Philadelphia.
