Cadaver dogs were tested in TWO TESTS with bodies dead less than 3 hours.
Carpet squares were used as an odor transporting media.
In test 1) The contamination occurred for 2 min WITHOUT ANY DIRECT CONTACT between the carpet and the corpse.
Comparative searches by the dogs were performed over a time period of 35 days.
In test 2) The contamination occurred for 10 min WITHOUT ANY DIRECT CONTACT between the carpet and the corpse.
Comparative searches by the dogs were performed over a time period of 65 days.
RESULTS = AMAZING.
The results of this study indicate that the well-trained cadaver dog is an outstanding tool for crime scene investigation displaying excellent sensitivity (75-100), specificity (91-100), and having a positive predictive value (90-100), negative predictive value (90-100) as well as accuracy (92-100).
CONCLUSION:
The fable about Reiser that you read in the newspapers is crap.
There is some explanation other than the "official" crap.
The accuracy of the dogs was 92-100% over a 65 day period (and in another test, a 35 day period).
The accuracy of the dogs was 92-100%,.. but that's not all. The accuracy figure includes tests up to 65 days after the body came close to, but did not touch, the carpet square.
The accuracy of the dogs on day one, must have been 100%, if the accuracy only reduced to 92%, after some 50-60 days.
