At a news conference on Monday, Los Angeles Police Chief Jim McDonnell said the LAPD saw video footage that "clearly shows" the missing 30-year-old crossing the U.S. border into Mexico.

From her initial alarming text messages to her family to her disappearance to Mexico, here's a complete timeline of Hannah Kobayashi's case. Kobayashi was taking a flight from Maui to L.A. on Nov. 8 and had a connecting flight from LAX to New York City later that evening that she missed.

The family of missing Hawaii woman Hannah Kobayashi say they intend to keep up their search despite the LAPD's assertion that she crossed the border into Mexico of her own accord.

Hannah Kobayashi was declared a 'voluntary missing person' after police said she entered Mexico alone several weeks ago.

Hannah Kobayashi may have been involved in a “secret marriage” before her November disappearance in Los Angeles, according to new reports. Los Angeles Magazine, citing unnamed sources, says Kobayashi’s family is now cooperating in an FBI investigation after her mother discovered a possible marriage-for-money scheme.

The family of a woman from Hawaii who vanished after landing in Los Angeles three weeks ago are expressing frustration with investigators.

Hannah Kobayashi, the Hawaii woman who’s been missing for more than three weeks after arriving in Los Angeles on a flight from Maui, has been declared a voluntary missing person, Los Angeles police said Monday.

The mystery began with a missed flight. On November 8, Hannah Kobayashi traveled from her home in Maui to L.A., where she failed to make her connection to NYC. Four days later, her family reported her missing.
