ok - so as there was no forensic evidence that JB did it - why did he just not make it look like a burglary and keep quiet? why alert the police by a false phone call? Because they may have been brave and go in straight away to try and save the children . then the times of deaths would have been accurately recorded. But of course you believe the official reports of TOD as 8am are false. Because it blows your theory out of the water. Again if he did do it why were the police convinced it was murder suicide ? Even to me it is pretty obvious the picture of the body with the gun was staged - so why were they so convinced that they argued with the family and would not accept their theory for so long?
Forensic ? He shot people. The carpets were removed. What forensics ?
Burglary ? Bit extreme that turning into a massacre with women & children being shot.
The police phone call has been discussed before. It is not a bad idea. Neville phoned Jeremy at home, Sheila has gone crazy, she is nutter, arriving after the police etc.
Time of deaths ? Obviously before 8am.
The police made mistakes early on but had the guts to admit it and change direction.
