Please don't speak to Lookout like that Scip.
I know where she is coming from and so do others for this has been discussed before.
Myth or not:
1. It has been said that someone heard a gun go off round about 10pm that night in the WHF location. Not much else near the farm except for the small cottages.
2. It has also been said that Sheila's fingerprints were found on one of the guns.
3. lookout is saying that she has read in police files that case shell from a gun was found and is merely asking if anyone knows about it.
Lookout constantly presents unproven allegations as facts and this is one of those instances. Mike's allegation that Sheila's prints were found on the shotgun is not evidence that they were. She is presenting it as fact though.
It is fair to point out that Mike took a reference that appears to indicate prints were found but only illustrated WHERE on the weapons the prints were found (referring to each location by a letter) not whether the prints were good enough to match to anyone or rule out as belonging to anyone. We have no indication that they were simply partial prints that were inconclusive.
Depending on Mike's objective that particular day he alleged Nevill and June's prints were the ones found on the rifle or Sheila's. He alleges whatever he feels like making up that particular day.
In the meantime just because a shotgun shell was found in a field doesn't mean it was fired the night of the murders. Even if Sheila's prints had been on one of the shotguns that doesn't prove she fired the shotgun on the night of the murders. Nor would anyone firing a shotgun out in the fields prior to the murders have any relation to the murders which were committed later with a 22 caliber rifle.
I consider the whole inquiry a waste of time but if people want to engage in such inquiry they should at least be using facts not misrepresenting unproven allegations from Mike as fact.
