Bridget, one of the problems I have is with all the little "extras" that are attributed to Jeremy. OK, mostly by Steve :D He "arranges" Sheila's body. He places a bible strategically. He takes the trouble to "brand" his father, something which must have taken considerable time because whatever was used must have need reheating. It would, IMO, have required total calm. A total disregard for the carnage and detritus of so many deaths. This is why I believe who ever was responsible must have been almost unaware of what they were doing. I don't think Jeremy could have done that, cycled home, calmed himself down to the point where he was coherent enough to call the police and then return to the farmhouse without visualizing what he had done inside it. I think at some point he would have gone into shock. It wasn't as if he had a background of violence.
Jeremy just wasn't the type to have killed in such a way without appearing that he did it. If he'd committed the carnage,,,it certainly would have showed,,,no doubt about that,whatsoever. He would have been in an unholy mess of blood and sheer exhaustion,,,,with possibly an immediate confession.
I've actually experienced a confrontation by a killer in the past. A young man whom I got on well with and was teaching him to write and to learn the English language. On the face of it,,he was a pleasant,,,willing to learn chap who put a lot of trust in me,,,,, and my daughters who were very young at the time,,,loved him because he was so happy with them and they with him.
However,,,this incident spills over to involve a big case,,of which I can't say much about,,,but this young man actually came to me,,blood on his clothing,,dishevelled,,the usual sign that he'd perhaps" been in a fight ",,so when I questioned him,,,he'd actually murdered a girl and didn't know what to do. I obviously directed him to the nearest police station where he gave himself up.
What the young chap didn't confide in was that he was having relationship problems,,,and I'm sure that if he'd told me,,,I could have helped him.
Like Sheila,,,he hadn't displayed any violence and was more than happy when he was with the girls and myself and said he felt " safe ". I would say now,that his " illness " was well hidden,,because of his "highs",,,then probably " lows " when he left our company.
At no stage would I have said that he was capable of murder. This happened in the 70's.
