Yeah, the fingernail lengths add much doubt about the conviction.
The post mortems also came up with different results in terms of stomach contents of five victims. It appeared that Shelia was up and about many hours after the others went to bed. She seems to have had some kind of snack = probably well after midnight.
By the way, and I'm not sure if this is the place for it, but my book about the Suffolk Serial Murders ( Ipswich Zero 6 ) was released yesterday, and I have a deep interest in this case too.
I'm 7 months into the research and I'm still of a very open mind. If anything, I tend to believe it was easier for Shelia to have killed the others. It really is the most amazing case.
I have friends who were in Essex Police ( I live in Colchester ) in the mid eighties and they have never really felt comfortable discussing WHF, and so I've not really pushed them on things.
I'm very concerned about the paint issue re. Aga / silencer etc. I wish someone from the police would give us their version. Was it a plant? It certainly seems possible to me that it was.
