I've just watched the documentary, it was very interesting and I'm not convinced of the cases being linked. There doesn't seem to be any evidence pointing to someone else. The suicide note identified by the son as being his father's handwriting makes me think that the Ward case was murder suicide though.

While I disagree with your assessment here, I appreciate your views on this.

The Ainsworth case is the key to the series of murders, because it occurred prior to all of the rest.
This is significant, because in terms of geo-profiling, it would seem probable that the killer was local to Wilmslow.
When a killer of this type is developing their M.O. they tend to start their crimes closer to home, and then as things progress, they often then move further afield from their geographical base.
A killer is essentially testing their boundaries; in every sense of the word.
And so when looking at a number of murders that share some stark similarities, it's always a good thing to look closer at which of theses murders appear to have chronologically occurred both first and last.
This should then give some indication on the journey the killer has taken; literally and metaphorically.
As I've said on several other threads; thinking like the police is one thing, but to really delve into the truth of any given murder case, one has to think like the killer would.
Aiming to determine their mindset, motivation, and methodology are all important areas on which to focus.
But we also need to consider the victim as well.
How a victim lived, is often an important indicator as to how and why they were murdered in the first place.
And so in terms of Mr and Mrs Ainsworth; is there anything in their life that specifically contributed to the reasoning behind why they were chosen by their killer to be murdered?
This isn't a case of a one-off spontaneous attack from a random mentally ill stranger. Far from it.
No, the slaying of the Mr and Mrs Ainsworth appears to have been a planned and calculated murder, carried out by a killer who knew exactly what he was doing, and who enjoyed the process of the kill; by seemingly writing a faux suicide note and planting some pills that he then scattered over the floor.
The killing of Mr and Mrs Ainsworth was staged, theatrical and deliberate.
The issue is that the police rarely prioritize focusing their efforts on looking at a murder from outside the box, as their primary aim is to find evidence via as linear a path as possible.
But this has its drawbacks because the SIO in this case, likely took a look at the suicide note, and then took the word of the son as gospel, and then wanted to close the book on it, and claim it as another case closed.
In other words, if a SIO of a murder investigation is handed an easy out, i.e. by having a suicide note that is then corroborated by a next of kin, they then have the green light to close the case and get the desired win.
The solving of cases is a numbers game at the end of the day, and some senior officers prefer favourable stats over actually uncovering the truth.
It then boils down to the professional integrity of the lead investigator on a case; as their remit is to close cases, not to "solve" them.
That may seem a rather sceptical take on it, but that style of "closing a case at all costs" policing, was particularly rife in the 70's, 80's and 90's.
Of course, in the case of the Ainsworth couple, the coroners officer (not the actual coroner) SD, then comes along and rocks the boat by suggesting that something feels off about the claim by the police that it was a simple case of murder-suicide.
And while I concur with her assessment, I am also not surprised that the police chose to make an example of her, by deliberately nullifying her attempts to question the integrity of the investigative team who were involved with the case.
Clearly, in this particular case, the police found it very difficult to admit their mistakes and error of judgement, and so regardless of whether SD was actually on the right track with regards to her challenging the murder-suicide claim, the police were never going to allow her to make them look incompetent or let her get away with breaking protocol.
It has meant therefore, that despite it being blatantly obvious that the Ainsworth couple were both murdered, the police chose to maintain their stance by dismissing SD as some kind of fraud; all in a bid to save face.
I would wager that within the next decade, the case will be reviewed again, and it will be found to be an error made by the police, and ultimately it will vindicate SD for her efforts in trying to shine a light on the truth.
Fascinating and utterly compelling cold murder case.
