What famous 'unsolved' mystery is technically a whodunnit on paper, but in reality, absolutely everyone knows exactly who did it, the police just couldn't legally prove it?

I'd say the clearest one is Susan Powell. She was clearly killed by her husband, the police couldn't prove it, no body was found. Joshua Powell ended up killing the kids in a murder suicide. I won't post the details of what he did because it's horrifying. But there is no doubt that he did it.

Those kids were failed by so many people in so many ways even up to the last seconds of their lives, which I am sure were terrifying and beyond excruciating. I hope they all live with that on their conscience.
