I agree with your last sentence NGB, they are suspect.
Do you think sheila was ever found in the kitchen? looking at the nightdress i would say no, unless her blood had gravity defying properties. But...we have have one male one female found on entry to property?
Andrea, I am yet to be convinced that Sheila was seen in the kitchen when the police burst in.
I think that the reports were jumbled. It was first reported that a female was seen, but I think this sighting was Ralph. [ His long hair ]. After entry it was reported one dead male, so a mistake occured.
These reports were made separately, so it did not come in the same report ie. one dead male AND one dead female.
I am not saying the Sheila was not shot once in the kitchen [although I have my doubts about that], but the raid team did not find her there.
There were cops all over the place, so I don't think it was likely that she fled up one of the staircases after entry was gained.
Of course this is only an opinion.
