I'm aware that someone jumping off a balcony under their own steam could theoretically be a murder or manslaughter case. My point is that we don't know if anything like that actually happened here. If there is no prospect of proving beyond reasonable doubt that it did, then there is not much for the police to do. It's a sad and frustrating situation for the family. But the police are not Miss Marple; their job is to catch criminals, not solve mysteries.
