Phone going dead, then Jeremy and police getting an engaged tone, and later when the operator reported that the phone was off the hook, proves there was someone alive at the scene at a time when Jeremy was elsewhere...
1) It is merely Jeremy's claim that the phone went dead and he tried to call back and got the engaged tone. The telephone company agent dsaid this claim did not match the phone reords which demonstrated the call was abandoned by the caller at Goldhanger not the caller at WHF.
2) There is no proof that anyone could have been alive at WHF. Had Jeremy gone back to WHF and hung up the phone after answering at Goldhanger then in that case he could claim that is evidence someone was alive at GHF. But he didn't so the phone could have been off the hook the entire time like the phone company claims.
Jeremy's attorneys had and still have absolutely no way to establish that the prosecution's claim is not true.
The prosecution's claim once again is that Jeremy disconnected his answering machine, dialed his house from WHF, went home, answered it, hung his phone up and lef tit hung up long enough to clear the line before calling Julie and the police.
Jeremy's own claims about waking up and answering the call requires the answering machine to not have been connected that night so either way that part would have to be true. Why would he disconnect it? It alone is highly suspicious that he disconnected it on the very night of the murders.
His claim the line went dead so he immediately dialed back and got the engaged signal doesn't match the phone company evidence but worse makes no sense. Why would Sheila do nothing as he dialed, dow nothing as he waited for Jeremy to pick up, do nothing as he spoke to Jeremy and to wait till he got his message out then to finally make him hang up the phone? If she did nothing to him as he did all those things and instead waited for him to finish then marched him upstairs why would she even bother to take the phone off the hook after hanging it up? Taking it off the hook would not prevent someone from hanging it up and dialing out. All it would do is prevent the phone from ringing but if she was keeping everyone upstairs at gunpoint they could not go down and answer a phone anyway so why would she need to leave it off the hook? Especially since he already got his message out. It was too late at tha tpoint. There is no point in taking it off the hook. Nor is there a point for Nevill to call Jeremy asking Jeremy to come disarm her since he was even taller and stronger than Jeremy and therefore as capable if not more capable of disarming Sheila himself. Moreover, he had the motive and opportunity to disarm Sheila because he was there near her having a motive to try to disarm her and being in a position to do so. It would take 15 minutes for Jeremy to answer, dress and arrive if he even answered. Nevill had no way to know the answering machine was off or that Jeremy would actually wake up and answer. He wa sin harms way the entire call. Why woudl he not try to disarm Sheila instead of daring her to shoot him as he sat on the phone to ask Jeremy to come disarm her? It makes no sense.
The evidence is that the killer went in the master bedroom and shot both parents there. Nevill managed to escape to the kitchen and was killed there after a struggle. It doesn't make sense that someone in a a crazy frenzy with a gun determined to commit murder suicide would wake up an intended victim, allow him to go downstairs to use the phone, allow the call to go through then take the phone off the hook and march him at gunpoint back to the master bedroom because of a plan to kill both parents in there.
The evidence suggests that Nevill only went to the kitchen once not twice. That he went to the kitchen after being shot in his bedroom and at that point he would have bee unable to speak if he even managed to call anyone.
As a whole all of this and the other evidence is sufficent to establish exactly what the prosecution contended and the jury found which is that Jeremy placed the call himself, answered it himself when he got home, hung it up on his end and that this eventually cleared his line.
There is no evidence to prove that anyone was alive at WHF to hang up the phone. The jury didn't buy it and the standard to get an appeal court to overturn such a finding is quite high.
Nothing short of someone at the telephone company claiming they concealed evidence of a subsequent call or a witness claiming to receive a subsequent call from someone at the house would suffice to get an appeal court to even consider taking action on this issue.
Unless Jeremy's lawyers can find either of those things he won't make any headway at all on this issue in court and the opinion of those who are convinced he made the call himself before leaving WHF will not change either.
If someone did make such claims then credibility would become an issue. Why didn't they come forward sooner and what evidence do they have to back up their claims... But without anyone to make such claims there is nothing at all that would warrant an appeals court to revisit the issue or people who believe he made the call to question their belief.
