I can't help wondering if it would have made any difference though. In almost all these cases, the person's body is found incidentally by a passerby. Appeals for information don't seem to achieve anything tangible. In Jay Slater's case, the police ignored the public, did their own thing, and found him after an extensive search. It's absolutely awful for the family, and I know in their position I would want lots of publicity and lots of searching, but I would think that, in the end, the case will resolve when the body is discovered by accident. I don't mean to sound cold-hearted.
