Police are still looking over video surveillance as they continue to search for a missing 16-year-old Edgemont High School student.

Christine Kang was captured on video just before 10:30 p.m. on Friday getting on to a Metro-North train bound for New York City.

Police say she left her home after an argument with her parents wearing light pajamas and no coat. "We're very concerned. We were hoping that she would have returned home by this point. Now we're concerned because of the elements, because of her clothing," says Greenburgh Police Chief Chris McNerney.

McNerney says Kang has left home before, but she's never been gone for this long. Police are asking anyone with any information to call (914) 682-5300.
