Have we learnt anything from the Maddie case?

[Alice Purjorick]

I have this bad feeling that we could be descending into yet another dog thread... not sure I could cope with that. lol

I couldn't either lol
Reading over the last 12 months no one knows hows a lock works nor a roller shutter* and seemingly few have bothered to look at a plot plan.... hey ho says Rowley 

*A roller shutter has 5 basic components ho hum.

have a look at the final report to see just how wrong you are...they gave a very specific reason

Beg pardon, that was Operation Task who thought that.

Does pus contain cadaverine ?

Does pus stink of putrefaction?  A quick Google will give you the very obvious answer to your question ... not forgetting another chemical ... putrescine.

In other words ... in my opinion the presence of cadaverine and putrecine on a plaster contaminated with pus from an infected wound would immediately have given Eddie the mental image of a bouncing tennis ball resulting in a joyful "woof" as he recognised the scent of chemicals he was trained to find.

I think his task was a way more difficult than that for any animal decaying will produce cadaverine and putrescine.
So that means it is not just a matter of detecting these two chemicals as he has to only alert to "human" odours.

I have that kind of shutter, but with a metal pole thing to turn. I did have a similar system on some silly space-saving wardrobe thing with a strap - and unless it was held at the right angle, while tickling its tummy, it would go into bolshy mode and jam.

If you have a hunt for one of the zillion dog threads, Rob, there are quite a few research papers posted. Good luck, though, there are dozens of them and they take quite a bit of wading time.

I use Google scholar  to get scientific articles.

you need to remember...none of the alerts can be regarded as evidence unless corroborated.....without corroboration all you have is barking dogs.....that is an undeniable fact. My opinion is that there was never a cadaver in 5A...and no one can disprove that

These dogs, which had already been used on multiple occasions by the Scotland Yard and by the FBI with positive results, are evidence collection means and do not serve as evidence; any residue, even if invisible to the naked eye, which is collected using this type of dogs, has to be subject to forensics testing in a credentialed laboratory.

Martin Grime, the dogs' instructor himself [20], mentions in his report: "Whereas there may be no retrievable evidence for court purposes this may well assist intelligence gathering in Major Crime investigations"

I have no problem with that, but at some point intelligence (if accurate) should lead to more concrete evidence. In this case, it apparently didn't.

Can one have an opinion the there was no cadaver in 5A?  Isn't that more correctly described as a theory?

[pathfinder73]

Eddie/Keela have been used by SY with positive results according to that report. Quite an eye-opener!

There is no cadaverine in pus.

True there are several of the volatile compounds found in cadaver odour which are also found in pus but no cadaverine and without it Eddie would not have alerted.

Why not?
