Where is the source that Sheila used to phone Nevill in a disturbed state.
For those who don't wish to rely on JB's evidence, SC's neighbour provided evidence.
Do you think it would have to be very loud to wake Nevill. Which is a surprise if Sheila wanted to shoot everyone while they slept.
It would depend on what stage of sleep NB was in whether he would wake easily or not. According to RB June was a light sleeper and NB not. As I said maybe SC woke June and NB but only NB got out of bed.
No one will ever know what SC's intention was leading up to the phone call. The physical evidence shows NB made the call and SC opened fire on June in bed with NB dropping the phone going upstairs and sustaining his gunshot wounds on the landing and stairs. SC then followed NB to the kitchen, beat him with the rifle and shot him another 4 times.
