The family of Hannah Kobayashi, a Hawaii woman who vanished while traveling to New York, has grown more concerned after viewing surveillance video.

Hannah Kobayashi, 31, vanished while on her way to vacation in New York City. Her phone last pinged at LAX on Nov. 11, which is the last time her family heard from her.

It’s been more than a week since Hannah Kobayashi missed a flight connection in Los Angeles. After a series of suspicious texts from her phone, the 30-year-old Hawaii woman has gone silent – and her family is desperately trying to find her.
