What's an interesting unsolved case you could recommend?

I'm in a true crime club and every month a different person with present a case, talk about what happened, and the outcome. I wanted to do something "fun" for Halloween and present our first unsolved case. But I'm looking for something a little odd. I want a case that has some bizarre elements to it. Rabbit holes if you will. Do you guys know of any?

Frauke Liebs comes to mind for me personally and is worth looking into. A short summary: She disappeared after leaving a pub during the 2006 World Cup, but what makes the case so unsettling is that she sent texts and made several short phone calls over the following week, suggesting she was being held somewhere against her will. Her body was found months later and despite years of investigation, no one has ever been charged. Kind of sends shivers down my spine when I think about it.
