Los Angeles Police Chief Jim McDonnell said there was no evidence that Kobayashi was a victim of human trafficking or was otherwise the victim of a crime. Investigators conducted “extensive” witness interviews and reviewed video surveillance but found no evidence of a crime. Kobayashi’s disappearance is now classified as a “voluntary missing person.”

“We basically did everything we could do at that point. She left the country and is now in another country,” he said, adding that law enforcement would be notified if she returned to the United States.

“A simple message could reassure those who care,” McDonnell said. He explained that the missing person case will continue until their safety is confirmed by law enforcement.

Sydni Kobayashi did not immediately respond to an emailed request for comment. Members of the public who belonged to the “Help Us Find Hannah” Facebook group, which attracted interest from more than 25,000 participants, shared a post from the group on Monday that said the family was leaving the group for ” Threats against them “close lives and the lives of their young children.”

During the press conference, McDonnell reflected on everything the family has been through over the past few weeks.

“I ask anyone who is thinking about doing this to think about the people you leave behind, your loved ones who will be very worried about you,” he said.
