There doesn't seem to be any mention of the car keys in the new update.
Perhaps A&S police no longer consider the keys relevant to the investigation. In the Shelley Morgan case, they mentioned two postcards in the public appeals, but eventually decided the postcards weren't relevant.
I'd suggest that the keys are indeed relevant, because they were dated from the same year that Melanie was abducted and murdered, and to find a full set of 3 Ford keys (including the red programming key) so close to the body, when the site wasn't a public footway or a place where people walked (apart from the man who deposited her body) is too much of a coincidence IMO.
What's interesting is that there were a full set of 3 keys. We know that they weren't (at face value) the keys needed for the killer's escape vehicle, and it would seem highly improbable that they belonged to Melanie herself, then we are left with the likelihood that the killer deposited them.
But why?
It means he would have been carrying an entire set of keys that weren't from his own getaway vehicle.
It would seem that the killer and/or man who deposited the body, placed the keys there intentionally, because to drop a full set of car keys and not realise, is unlikely.
However, I think that there's a possibility that the keys may not have necessarily been put there at the same time the body was. In other words, the killer may have revisited the site and put the keys there by Melanie's body afterwards; for whatever reason.
It is strange that the owner of those keys can't be traced. I am not sure the statistical likelihood of that happening, but the killer seems to have been lucky in that the keys couldn't be definitively linked or traced to a specific vehicle and/or owner.
It's almost as if the killer was aware of this.
So what kind of man would have the awareness to know that the keys couldn't be traced back to him?
Someone who worked with cars and similar vehicles.
As I've mentioned before, at the time of the murder there was a 2nd hand "Ford" garage located just a few miles east of the deposition site. Unfortunately, because that garage is still open and functional today, I am not permitted to comment further.
All I would say it that If I was investigating the case, I would certainly have questioned the 2nd hand official Ford car dealer/ Ford garage that was (and still is) located relatively close to the deposition site.
Could the killer have visited that garage and purchased a 2nd hand Ford, that he used to transport Melanie's body?
Was there a Ford car that was registered as scrapped, but the killer still had the keys for the car...and then chose to go BACK to the deposition site some time afterward, and then drop the keys for the Ford car he had previously used to abduct, murder, and then transfer Melanie's body in?
Perhaps the police could look at the DVLA registers for any Ford vehicle that was SCRAPPED in 1996. It can't have been sold, because all 3 keys were found by the body.
But when you scrap a vehicle, you get to keep the keys.
I think that's what the killer did; he scrapped the Ford car he had, and then took the keys to the deposition site at a later date.
The Ford keys are IMO, an absolutely crucial clue to the entire investigation.
The keys have been ruled out by the police as having been the killer's, because the killer seemingly couldn't have used those same keys to then drive off after he deposited the body.
However, that's not necessarily an accurate assessment, because he could have driven off in his Ford car, and then after he scrapped the car in a bid to destroy evidence, he then chose to go back to Melanie's body and then place the Ford car keys from his old car.
When he went back to the deposition site, he must have been driving a newly acquired vehicle, because otherwise he wouldn't have been able to get back home without a car.
The keys are IMO, absolutely crucial to solving this case
