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. She didn’t say where she was going or how long she'd be away, "but that was normal." Michele, 22 at the time, was always on the move, and she rarely told her family where she was headed. "That's why I didn't think anything of it," says Jonas, whose name has been changed for this story.
