VIDEO: Fire officials are investigating what sparked a fire at a commercial business along State Highway 2 near E. 104th Ave. in Commerce City Monday afternoon. Few details were initially available, but a Denver7 news crew observed a business fully engulfed in flames as fire crews worked to attack the fire from a ladder truck above the flames. A large plume of smoke could be seen from several miles as first responders blocked access to the facility along CO-2. The fire started at approximately 11:04 a.m. Monday at a business in the area, South Adams County Fire Department officials said in an update later in the day. Employees inside the building were able to get out and no one was injured. The fire was out by around 1:20 p.m. and investigators were in the process of investigating what caused the blaze.
