Vasquez and Fogg had cited as proof of arson the fact that the front door’s aluminum threshold had melted. “The only thing that can cause that to react is an accelerant,” Vasquez said. Hurst was incredulous. A natural-wood fire can reach temperatures as high as two thousand degrees Fahrenheit—far hotter than the melting point for aluminum alloys, which ranges from a thousand to twelve hundred degrees. And, like many other investigators, Vasquez and Fogg mistakenly assumed that wood charring beneath the aluminum threshold was evidence that, as Vasquez put it, “a liquid accelerant flowed underneath and burned.” Hurst had conducted myriad experiments showing that such charring was caused simply by the aluminum conducting so much heat. In fact, when liquid accelerant is poured under a threshold a fire will extinguish, because of a …show more content…
It was then that Hurst thought of the legendary Lime Street Fire, one of the most pivotal in the history of arson investigation.
On the evening of October 15, 1990, a thirty-five-year-old man named Gerald Wayne Lewis was found standing in front of his house on Lime Street, in Jacksonville, Florida, holding his three-year-old son. His two-story wood-frame home was engulfed in flames. By the time the fire had been extinguished, six people were dead, including Lewis’s wife. Lewis said that he had rescued his son but was unable to get to the others, who were
