I don't believe Sheila froze. She was just easy to control.
Physically weak & uncordinated, half asleep, not knowing what was going on and under the influence of the sedative effects of Haloperidol.
The last two people to see/hear her alive - Bamber/housekeeper both commented on how docile she was. After observing Sheila, Bamber rang Julie to tell her 'tonights the night'.
The evidence shows Sheila put up no/minimal resistance. Which allowed Bamber's first shot to be a fatal one. Although not instantaneous.
Hi Adam,hope you are enjoying your Satarday night.I thought i would remind you exactly what Vanezis said about the non fatal wound,termed the lower one. Q-What about the lower one? A=The lower one is a different matter,because the lower one has injured soft tissue and fractured bone,but has not actually immediately damaged any of the vital organs,such as the brain or spinal chord,and so,although by means of haemorrhage and secondary effects from this wound,in my view it would PROBABLY,IF LEFT NEGLECTED,have been fatal.It was not as immediately damaging as the upper wound. Q-So what you are saying is,if someone had received just that wound,and nothing had been done to staunch the blood or otherwise reduce its effects,that could EVENTUALLY be fatal? A-It COULD be fatal,either fairly quickly from,POSSIBLY,an embolism through the brain,or much more SLOWLY through haemorrhage,but in any event,IF LEFT NEGLECTED,it would certainlly have caused a great deal of morbidity,if not fatal outcome. So,at no time did Vanezis say the wound was definately a fatal one,even suggesting Sheila may have survived without immediate treatment,as long as a brain embolism did not occur.Therefore his testimony about the outcome of the first shot is totally inconclusive.One can only conclude it MAY have been fatal if no other wound was inflicted.
