Jonas says he doesn't remember exactly which day his sister disappeared. It was sometime in early September 2015, he says, when Michele grabbed her suitcase and left.

"That's why I didn't think anything of it," says Jonas, whose name has been changed for this story. Michele would turn up again – in a week, two at the most. That, he says, is always what happened when she left on a trip.

The fact that she hadn't been in touch for weeks, even though she had always checked in before, wasn't enough.
