SUPERIOR, Colo. — Investigators are still trying to determine what sparked a massive fire in a suburban area near Denver that burned neighborhoods to the ground and destroyed nearly 1,000 homes and other buildings.
Three people are missing following the inferno that broke out Thursday.
Boulder County Sheriff Joe Pelle said Saturday authorities were pursuing a number of tips and had executed a search warrant at “one particular location.” He declined to give details.
A sheriff’s official who declined to provide his name confirmed one property was under investigation in Boulder County’s Marshall Mesa area, a region of open grassland about 2 miles ( 3.2 kilometers) west of Superior. A National Guard Humvee blocked access to the property, which was only one of several under investigation, the official said.
