The other occupants of Apt 5a before and after the McCanns visit.

Is it known for sure that the place was occupied immediately afterwards ?

I'm not sure when the key was handed back the first time.

- At the Ocean Club, apartment 5A had been booked for the nights of 28 April through 4 May (vacating on 5th); the family stayed in apartment 4G from 4 May through 2 July (vacating on 3rd)
- Apartment 5A was subsequently let between 12 and 19 June (to friends of the owner); 28 June to 12 July (to three people with Irish names); 12 to 19 July (to an English couple) and 19 to 26 July (to a family with Southern Asian names).

Its very mysterious that those people were not on any statement list or asked for mouth swabs to check DNA profile.
  Surely their DNA should have been checked even if only for elimination.
They are the most likely to have x contaminated, given the time scale of cadaver Scent.
I also noticed that before the McCanns there was a surgical assistant stayed at 5A .Depending on her duties there is a possibility of X contamination there too. Even a small part of a body being removed is cadaver
Even extracted teeth are used to train cadaver dogs as they are easy to obtain. I have put a video on another thread which shows Eddie in the Jersey childrens home and he barked approx. 10 times..............Surely not 10 bodies. I think he barks at all body fluids. Am I correct?
There are so many possibilities as to the dogs alerts.

Which is precisely what Grime tells us.     

Also as the McCanns moved into the Payne's apartment during the night of the 4th May - and stayed there until they were given another apartment - then as they were wearing the same clothes they'd worn on the evening of the 3rd, one would think that if there was any 'contaminant' on them - it would have been transferred - and  Eddie would have alerted in the Payne's  apartment too.

Yes Benice.
 you are correct McCanns moved to Paynes and afterwards to another Apartment, but no alerts in either.
So where did these alerts come from?  It is a puzzle that has something to do with 5A, 5A residents or the reasons the dog alerted.
