Taff Jones was on scene for about a half hour. He rapidly concluded it was murder suicide. Woodcock recorded his initial theory. Evidence proved that theory wrong but he supposedly never wavered.
His theory was that Sheila woke up when she heard her father go downstairs. She heard him on the phone with someone and then grabbed the gun and beat him with it and shot him. Then she went upstairs to kill her mother and children. The commotion in the kitchen woke June and as she was walking out the door to investigate Sheila shot her. Then she shot her kids and killed herself.
Right off the bat he misread the scene by ignoring the blood in the bed that proved June had been shot in bed. His theory featured Sheila grabbing the gun after Nevill was already on the phone with Jeremy which makes no sense. It makes no sense for Nevill to call Jeremy then for her to grab the gun and Nevill to at that point convey to Jeremy that she had the gun. Nor would it make sense to beat Nevill when she could have just shot him. She would have had a hard time beating his head in if he had not already been shot first. He was much taller than her so how would she be able to bash his head in? He had to first be beaten onto the ground to be able to then bash his head in.
After it became clear June was killed in bed and that Nevill was shot upstairs in the bedroom with her then after the gun was empty that is when/why the kitchen fight happened, one has to seriously wonder how Taff Jones could still keep his theory intact. It seems this would explain why superiors were concerned about the way Taff Jones was approaching it and why they decided to have an officer of the required rank (a higher ranking officer was supposed to be in charge of such an investigation) reinvestigate things.
