Roxy and Fire Investigator Marnie work for the City of Oroville Fire Department and are part of a interagency task force, Butte County Fire Investigation Team. Accelerant Detection Canines have been vey successful assisting in fire investigations. Accelerant Detection Canines are a tool in locating traces of ignitable liquids. During training Roxy is imprinted with the odor of 50% evaporated gasoline. A primary positive response (alert) by Roxy in the presence of an ignitable liquid is indicated when Roxy assumes a “sit” position. This response is then reinforced by a food reward. This is the method of choice since food is a high priority. Roxy is trained on a daily basis to discriminate between pyrolysis products normally found at fire scenes and pyrolysis products containing ignitable liquids. Roxy is 100% accurate during her daily training. This methodology is very efficient in locating the exact spot for the Investigator to collect a fire debris sample to ensure the high probability of a positive result from the crime laboratory, once the sample is analyzed. In case studies, the canines were found to be capable of detecting 2/100th of a microlitre of evaporated gasoline, this is lower than the detection limits of most machines used today.
