In the somewhat similar Caroline Harris-Reed murder, the killer forced his way into the flat after Caroline and her friend saw him peeping through the spy hole, and opened the door to ask him what he was doing. He was a local sex offender, who prowled the streets and then decided to try and prowl inside a block of flats. He gained access to the flat of the first residents he encountered.
I don't see any real link between the murder of Caroline Harris-Reed and Joy Hewer.
Firstly, Caroline was murdered in a newly renovated 3 storey Victorian house; whereas Joy was murdered in a 6th floor flat in a 12 storey tower block.
What the Caroline Harris-Reed murder does highlight brilliantly however, is what I said about Cold Cases often remaining unsolved because it's often based on what the police can actually prove, and not what they know; or what they think know, to be true.
It is clear that the man who killed Caroline was a man named Frank Harvey; who lived in a flat directly opposite the flat where the murder took place. His flat was level with the flat opposite.
He had a distinct and relatively rare nasal deformity that the murder victim's friend (Catherine Osborne) noticed after having gone through a 2 hour ordeal by the man who would later stab her friend Caroline to death.
Frank Harvey's first trial was a joke, because the jury couldn't reach a verdict. It then went to a retrial.
His 2nd trial was very much hush hush, but only because at the time he had already been charged on a violent assault on an 18 year old girl who had been walking her dog near his flat. He grabbed her from behind and threatened to kill her if she didn't do what she was told.
He had already served 10 months for this offense and so when his retrial took place concerning the murder of Caroline Harris-Reed, he was set free immediately.
The case is a prime example of the fact that everyone knew it was him; the police believed they had their man. But he was still acquitted.
However, the fact that he was proven to have been a sexual predator, had the exact same nasal deformity as the man who killed Caroline, and who lived opposite the murder site; it is merely a case of the jury not having the courage to convict a clearly dangerous sexual predator.
One thing that is interesting about the murder of Caroline Harris-Reed, is that her killer allegedly cut off her breast as part of his macabre post mortem mutilation.
Her friend Catherine Osborne only survived because she feigned illness.
And so even though I don't see many similarities between this case and that of Joy Hewer, there may still be a chance that it was indeed the same man. I say this because even though Caroline was murdered 14 years prior to Joy Hewer, the idea that the killer was free to walk the streets and the case was never "officially" solved, it is absolutely certain that the police knew who the killer was; but just couldn't convince a subjective and flawed jury to reach the correct verdict; as is often the case with many jury members who are mandated to make crucial decisions on a subject they know hardly anything about. That's the major flaw with the archaic and outdated jury system that we have in the UK.
It does make me wonder what happened to Frank Harvey because he was a convicted criminal who was charged with indecently assaulting the 18 year old girl, and so because he was also almost certainly the man who murdered Caroline Harris-Reed, then there's a high probability that he may just have killed and/or maimed others.
Of course, if the name Frank Harvey appears in the records pertaining to the London Healing Mission, then maybe he could also be a potential suspect in Joy's murder. it's a long shot of course, but not an impossible hypothesis.
