The FBI has been pulled into the Hannah Kobayashi missing persons case after it's been discovered that she may have engaged in an immigration marriage scam. Hannah Kobayashi is reportedly married, and her new husband was on the Los Angeles flight with her.  She’s now listed as voluntarily missing. Police say Kobayashi indicated her intention to "disconnect from the world."

McDonnell announce that investigators tracked Kobayashi to Mexico and have her on video walking into that country alone with her luggage on Nov. 12, four days after her arrival at LAX. 

It’s coming up on the one month mark since Hawaiian beauty Hannah Kobayashi went missing.   The 30-year-old got on a flight along with her ex -boyfriend, headed on a bucket list trip to New York. She intended to visit an aunt in upstate New York and take photos at a DJ's show in Brooklyn.  The pre-planned trip was non-refundable so Kobayashi and the ex agreed to fly together to New York and go their separate ways upon arrival. The flight arrives at Los Angeles International Airport 9:53 p.m. The connecting flight to JFK in New York was scheduled for 11:00 p.m.   Kobayashi never made it to the connector, and the search was on.

Kobayashi was seen in the next few hours at multiple sights around Los Angeles, then all communication stopped. A worried family reports the woman missing, and a wide scale search by police was launched.
