Well there's a contradiction " most of the area appeared to be on his side ".Since when ? You've said yourself that those you know/speak to all believe him guilty. Weren't EP employed to go knocking on doors asking occupants if they knew him,then in the same breath telling them that " he'd murdered two little boys you know ".Known as putting words into people's mouths,that being the case who were they all going to believe ?
EP had been the picture of desperation.
Certainly, they/we do, now, but at the beginning, AND because of information given by Jeremy, MOST readily accepted that Sheila was responsible. Many started to squirm a little when Jeremy's behaviours caused them to have doubts. YES, EP, as part of their investigation did a door to door, just as they did in the Diane Jones case. I don't know from where you get the information that they told people "He's murdered two little boys you know" I can only believe it to be apocryphal, like much else that gets bandied about here.
