Courtesy Andrew Lussie / US Forest Service Officials with the US Forest Service are refuting reports they’re close to pinpointing what or who caused the massive East Troublesome Fire in Grand County. On Friday, a US Forest Service spokesperson reiterated that the investigation has revealed the fire was “human-caused” but said there is no word yet on exactly what started the deadly blaze. “There is no update to the investigation,” she said. “The investigation is still in progress.” Multiple people have contacted the Sky-Hi News in recent days saying that investigators are close to filing charges. However, the USFS spokesperson said that investigators are still interviewing potential witnesses and gathering information, and they are not making any announcements about a cause at this moment.
