Researchers from the University of Alberta and the Royal Canadian Mounted Police, working in tandem, have developed a new computer program that can pinpoint the presence of gasoline in debris taken from a fire scene. What makes this so important is that gasoline, according to the researchers, is the most common accelerant found in arson fires; evidently preferred by arsonists everywhere. By making it easier to detect, and confirm, the presence of gasoline, you stand a good chance of making arson easier to prove and less profitable to attempt.
What makes the new tool so helpful, is that it often is difficult to confirm the presence of an accelerant in debris taken from a fire scene. No two houses, buildings, or fire scenes, are exactly alike; they contain different mixes of materials. Different materials leave behind different chemical compounds when burned, and these can mask the presence of an accelerant such as gasoline. The researchers, in effect, developed a computer filter that can by-pass the background noise to pinpoint the tell-tale signs of gasoline. They developed their tool by examining data from 232 samples taken from fires across Canada; by using real-life debris rather than merely relying on simulations, the researchers say their tool is dependably accurate.
Currently, determining whether there are traces of an accelerant left behind at a fire scene is time-consuming work. According to the researchers, the Royal Canadian Mounted Police have two separate forensic scientists examine each sample to see if their findings agree; this can take several hours for each sample, and there normally are three to four samples per fire. The newly developed computer program shrinks this time substantially. The first scientist still will have to analyze the debris herself, but will be able to confirm her findings in seconds, rather than hours, by using the computer program. A second forensic scientist will not have to analyze the debris unless the computer program’s findings disagree with those of the first scientist.
To show how useful this new tool can be, think of the case we talked about the last time: Maier v Allstate Insurance Company, 41 A.D.3d 1098, 838 N.Y.S.2d 715 (3rd Dept. 2007). In that case the government fire investigator used a specially trained dog to determine that traces of an accelerant were found at the fire scene, but the lab report came back negative for the presence of an accelerant and the plaintiff/insured challenged the dog’s reliability. Though the insurance company still was able to establish an arson defense, think of how much more credible its case would have been if this new computer program was able to unmask the traces of an accelerant and confirm that the fire was deliberately set.
To show how widely this new tool can be used, you only have to consider the arson fires that have been in the news recently here in New York:
- A man was arrested and arraigned for intentionally setting a mattress on fire in a Coney Island, New York high rise and causing the death of one police officer from the resulting toxic smoke, according to a report in the New York Daily News on May 1, 2014.
- On Long Island, a Sagaponack man was arrested for intentionally starting a fire in a house on Dune Road in the Southhampton Village of Water Mill on Saturday April 19, 2014, according to a report published by WABC 7 on April 20, 2014.
- Three men were arrested in June 2013, for attempting to burn down the unoccupied residence of one of them in Hartwick, which is located in Otsego County, in order to recover $50,000 in insurance proceeds, according to the New York State Department of Financial Services.
No one can be sure just how helpful the researchers’ new computer program will be to any one particular arson investigation. At the very least, though, it should put answers into arson investigator’s hands more quickly, which should help them ask the right questions of the right people sooner rather than later. As a compliment to, rather than a substitute for, trained investigators, it should prove invaluable.
