Fire scenes with a strong odor of ammonia
In the last two months, I have investigated three fires that contained a strong odor of ammonia. Two of the fires were structure fires on opposite sides of the parish. The other one was a vehicle fire. All three of these fires were definately arson. On the first fire, I initially thought that the ammonia was to conceal the odor of the accelerant from the K-9. I do not believe that these fires are connected in any way. Does anyone know how ammonia could be used to start or accelerate a fire? Or has anyone else encountered this problem.
I.E. Samples were taken on all three scenes and the chemical analysis came back with three different accelerants (kerosene, paint thinner, and gasoline)
