Claude Heroux was a minor character in Stephen King's novel, It.
Heroux was known to be an arsonist, starting many fires in the woods the summer of 1905, the biggest being outside Haven, Maine Big Injun Woods. He was one of four organizers to a Union talks that summer, and the only one of the four to escape murder at the hands of It, or It influencing William Mullers men: Tinker McCutcheon, Floyed Calderwood, Lathrop Rounds, David Grenier, and Eddie King.
It was speculated that he was only a part of the Union organizers due to his love of David Hartwell, that as a man who spent his life as a loner, he lived his life like a dog does for its master in Hartwell. Mike Hanlon speculates that he while he might have avoided murder that night because he had a knack for knowing when trouble was coming an getting out, but didn't believe he would leave Harwell if that were the case - but it was more likely he escaped while Harwell was being fed his own toes.
After that night he became a ghost of a man, showing up long enough in bars to eat and swear revenge on Hamilton Tracker, William Mueller, and Richard Bowie. He likely avoided being arested and tried for arson because it was feared what he might say on the stand.
On September 9th, 1905, Heroux went to the Sleepy Silver Dollar bar and killed William Mullers men: Tinker McCutcheon, Floyd Calderwood, Lathrop "El Katook" Rounds, and Eddie King with a woodsmans double-bitted axe. The men at the bar ignored this slaughter, later saying it was like staying out of politics. The only man to escape, David "Stugley" Grenier, did so by crawling through the outhouse, and left town shortly after as he became a laughing-stock. After the slaughter, Heroux sat at the mens table until the cops arrived to take him to jail. That night after word spread, men broke into the jail and lynched Claude on an old elm tree over the Canel. Claude was apparently vacant, and didn't fight the men at all. Mike Hanlon speculates this event is what triggered Its hightened period of terror this time around, including the event at Kitchener Ironworks in 1906.
