He only had a brief look and Nevill had long straggly hair - I guess it was the style that is called a comb over. He didn't have time to analyse , weight, height and build. He saw the long hair and made a snap decision, which he corrected on entry.
Speaking generally, I would have thought it less likely that policemen would make mistakes about things like the time of a telephone call than the average person would, because it's their job to get things right. Jeremy's mistake is understandable, but it's not understandable that the police reported finding two bodies downstairs at least FOUR times.
The accusation that the police lied in their statements is based upon the evidence of the logs in which there are references to a second body found in the kitchen. Some people have tried to say that one mistake just got repeated over and over, but that just won't wash because different reports give different information.
I won't try to give the details here, but anybody can confirm or deny that the following pieces of information were given separately.
1 That a female body was seen in the kitchen before the police broke into the house-I am of course referring to the sighting by PC Collins.
2 That a dead male and a dead female were found on entry.
3 That a call for an ambulance was made in which two bodies were referred to.
4 That when the upstairs part of the house was gained, it was reported that THREE more bodies were found and not four.
5 That in a statement by one Neil Davidson, the following description of the scene downstairs is given: “One murder and one suicide.”
That is one hell of a lot of mistakes. I would say that they can't all be just mistakes, because they all add up to the same conclusion. Those cops, first found Sheila downstairs having, apparently, committed suicide and lying on the kitchen floor where she was visible to PC Collins when he looked through the window.
