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.

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.

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.
