I think in the timescale given there was ample opportunity to move evidence well out of the area to a much greater distance, and more remote, than that which has been searched currently, but ONLY if a capable vehicle was available. Not even the most moronic idiot would snatch a child in a faulty vehicle, which leads me to question the reports about his erratic driving on Monday evening being related to his gear/ clutch/ whatever mechanical problems. I think the vehicle problems were unexpected the next morning when he was leaving his home in a hurry, hence a more local disposal. The searches seem to be focused on Afon Dulas north of the Dyfi.
