Second, any idea how many times the air is exchanged in motor home that clocks 500+ miles ? Wouldn't thoe conditions be slightly different than a closed building ?
Minion, try to read the article, ok? If you read it, you'll note that first of all they used very small samples. Secondly, the scent remained even after the articles had been removed. Thirdly, the motorhome was probably closed during the trip. This is a luxury motorhome, not a beat up 1957 land yacht with no heat or air conditioning. Fourthly, blood decays just like any other material. There was also hair. Both of these substances were used in the tests. In Dusek's (ludicrous) theory, the child had been in there a mere 72 hours prior at the earliest. If she had been in that motor home, the dogs would have alerted their handlers.
How do you suppose they manage to use dogs to track people in the out of doors, Minion? Sometimes these dogs can track people days and even weeks later. How much air circulates in the great out of doors, Minion? Your arguments lack the substance of logic. Think about it.
