The first lawsuit filed in connection with a wildfire that destroyed over 1,000 homes and other buildings in suburban Denver claims that sparks from a power line started December's blaze. The lawsuit was filed against Xcel Energy Thursday, March 31, 2022. It says that its power lines and equipment were a "substantial factor" in the cause and continuation of the wildfire.
