My first thought was that he'd be ID'd from his tack - so where is it? You know what he wears, what the bit/noseband are, what colour sheet (possibly with a logo). And it doesn't say that the ditch was on the firing range or if it was even near to where he was being ridden when the rider fell off. As for fur in the same colour... are they saying they found a skeleton, then, with no dried hide from which they could still obtain a microchip reading (from the neck hide)? Presumably the inference is that he has been eaten entirely by scavenging animals, with no hide left, and those same animals have neatly carted away his leather bridle and saddle to eat somewhere else? So what about the non-leather metal parts of the tack, the girth, and the sheet? I'm not convinced, either!
