I realize this is a little more like "current events" than "true crime," but I think it's one of the strangest and saddest crimes I've yet encountered.
In NYC, a man has just been scentenced to jail for killing a guy who
asked him to do it so the murder could be set up to look like a random street homicide (the victim wanted to leave his life insurance money to family.) Evidently, the defense portrayed this as "assisted suicide" and not insurance fraud.
