A reconstruction is unnecessary. Close scrutiny of the forensic evidence reveals everything we ever needed to know. Jeremy Bamber's attempt to implicate his sister by creating a murder/suicide scenario within a locked farmhouse was his undoing.
Team Bamber have had 30+ years to come up with evidence in support of Jeremy but failed miserably. The reason for this failure is very simple, there isn't any. All the scratched mantelpieces and bloodied silencers in the world will never add up to anything capable of overturning Bamber's conviction.
The fact experts didn't enter WHF other than Dr Vanezis who said he wasn't aware of the position of cartridges (casings) and where NB was shot says it all imo:
http://miscarriageofjustice.co/index.php?action=dlattach;topic=206.0;attach=742Afaik to scale drawings of WHF were never produced.
There's too much that doesn't add up for the 'JB burst into his parents bedroom and shot them' scenario:
- None of NB's blood was found in the bedroom: bedding, carpet despite confirmation from Dr Vanezis that the facial wounds contained a rich blood supply
- Two casings in the left hand corner of the bedroom (lhc upon entering)
- One casing on the transition strip
- One casing on the landing
- The casings above do not support the theory NB sustained gsw's whilst in bed and getting out of
- The gsw's NB sustained to his face and the shoulder and elbow/chest to his rear all had downward trajectories. How could he sustain all these gsw's whilst in bed and in the process of getting out of? Bearing in mind the gsw's to his face were fired at a distance of a few inches and the shoulder and elbow shots from a distance of at least 2' feet away.
NB shot on the landing stairs and main staircase fits with all the physcial evidence imo. The only way to prove this one way or another is by experts carrying out a proper reconstruction which afaik to date has never been carried out.
