He could have said nothing. That could be construed as deceitful by some for example yourself. IMO he was simply being honest and truthful and he trusted what his dogs alerted to. He knows far more about them than you ever will yet you scrutinise the videos along with others to find things to poke at him with.

There are scent cones & there are scent pools. If the dog/handler couldn't establish the source of the scent, how could the handler differentiate between the dog alerting at a source or a location somewhere within the cone? That principle applies to some of the other alerts.

Having read about scent cones I believe Eddie would have zigzagged back to where the scent was strongest before alerting.  With scent pooling he would get his nose in the middle and alert IMO.    Davel said cadaver scent won't pool. I disagree with him too by the way misty.

Do you know how cadaver scent moves Davel? I imagine that Martin Grime knows more about it than you do.

He doesn't seem to..scent moves via Brownian motion...it does not collect anywhere..it dissipates

A scent cone may be present when there are physical remains present....with scent being constantly produced

Dissipates in what?

What about when the scent has adhered to a permeable substance, like the fabric on the sofa? As the odour dissipated its pathway into the atmosphere was blocked by walls?

Open windows and doors....if the scent molecules had been absorbed by a porous surface then surely they would be physically detectable

Surrounding air and out through windows  and doors..remnant scent lasts in a completely sealed room but would not in one with open windows and doors....and certainly not an outside flower bed

Grime days the scent will build up....pool..in a certain area...it won't..it will dissipate
If cadaver odour persists, it might persist in fine particles, for example, skin cells that come off a cadaver.  Now I could think that it is possible that heavier than air particles like cells are blown around in the air currents and could accumulate in certain areas.
So rather than odours being concentrated it is the source of the odours that are gathered.

There isn't a scientific test to confirm that which is acceptable in court. It was used in the Casey Anthony trial & was part of the reason the jury didn't convict - the test developed was only capable of identifying some components of cadaver odour.

So what's with the Brownian movement stuff then ?

The air in the room when the doors are shut and more if the doors and windows were opened.

So the scent moves with the air flow?
