However, the Feb. 10 two-alarm blaze at 1041 Castlewood Drive was deemed "accidental in nature," according to the 13-page investigation report.
The exact cause was undetermined. But it likely involved one of the non-flammable rounds hitting or knocking over flammable household products, the report said.
The fire began shortly after police launched 12 tear gas rounds into various parts of the house. Police were trying to ferret out as many as six armed robbery suspects believed to be inside. However, it was later determined that the suspects had slipped away before police established a perimeter.
According to the report, the tear gas rounds were non-flammable. But one of the 37-mm projectiles fired through the back door could have penetrated or knocked over a household product containing flammable chemicals. At that point, vapors could have been released and ignited when reaching an ignition source, such as the flame from a nearby water heater.
