Whatever,or rather 'whoever' Nevill was referring to when he phoned Jeremy,he clearly stated his 'daughter' when he phoned the police himself.
This is a crucial point, because once you see what Jeremy says about the phone call in his 11th September 1985 police interview, it becomes more obvious by the moment, that even before Jeremy got around to calling the police at 3.36am, that police already had information to hand in the form of Ralph Bamber contacting the police himself (at 3.26am), telling police that his 'daughter has hot hold of one of his guns'...
We now know, that Sheila's fingerprints were found on a shotgun at the scene, along with Ralph Bambers fingerprints, and it remains a distinct possibility that the gun referred to by Ralph Bamber in his 3.26am call to police, was with reference to this shotgun, not the anshulz rifle, which has been described as the only firearm used in the tragedy...
perhaps the person taking Jeremy's call, paraphrased what Jeremy said his father had said, correctly or otherwise, altering "She has" into "Sheila has", which in one way or another, it allowed the police to present the argument at trial, that Jeremy had not received a telephone call at all from his father, and that he had introduced such a call, making mention of Sheila's name, to fool police into thinking that Sheila was solely responsible,when if the truth be known, what Jeremy had to say about it had not been recorded accurately...
