Good morning.
With the heaps of sites and links on this case,it's easy to get bogged down with conflicting stories on who or what was at the scene,and which of it is true.
I did see a section of there having been an Alsatian being brought to the farmhouse. At that particular time,Jeremy was outside,and as far as I can gather,because the dog was trained in sniffing out explosives and the like,there'd been nothing to detect on Jeremy. Whether the dog was ordered to search Jeremy,I don't know,but I'm pretty sure if there'd have been a scent,the dog would have reacted in some way.
