Nearly a month after a woman from Hawaii went missing after arriving at LAX, the family is demanding to see the surveillance footage of her crossing the border into Mexico.

The sister of missing Hawaii woman Hannah Kobayashi is demanding police release surveillance footage that shows Kobayashi voluntarily walking across the U.S.-Mexico border last month after getting off a plane in Los Angeles.

Police say a Hawaii woman who disappeared after landing in Los Angeles was seen crossing into Mexico alone with her luggage and is not considered missing.
