Yes, but whether W disappeared just before FD got home as FM has relayed, or whether he disappeared just after 10am as Beacroft theorizes, both of those are before HS left for bingo. It seems that people are suggesting he was laying down under the balcony at FGM's house listening to convos and such, and saw W and got up and ran after him and took him. I'm saying he would be screaming when he awoke if PS had rendered him unconscious and hidden him for later abuse. All of that sounds just too way out there, imho.
The theory about running into him with a car.. why would they hide that? It wouldn't have been like it was deliberate and it wasn't even like they'd be expecting or necessarily looking out for a small child behind their vehicle when backing out or whatever. People get into their habits about driving, and how they pull out of their driveways and such, and I could see that as a possibility for sure, I just can't see why the couple would have hidden it, - at least ongoing for over five years? They really, imo, had nothing to lose by admitting it, other than embarrassment perhaps, and grief and sadness, possibly depression, etc. But admitting it wouldn't have been like they'd go to prison for it, right?
By the time GJ set his sights on PS, PS could simply have blamed it on his deceased wife even if he'd done it himself, and been done with it - admitted he covered it up for her because she just could not handle the grief and especially on top of her illness, etc. I think police would have been understanding and not too harsh with him or them. imo. Also, they had examined the vehicle(s). It would be interesting to know if only one of them, or both, and whether HS's vehicle was still owned when GJ set his sights on PS. In September 2014, surely police checked out all of the neighbours' vehicles for signs of hitting something?
