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

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.

Kobayashi was seen in surveillance video around a downtown Los Angeles Metro train station with an unknown person on November 11, her family said.
