Investigators Probe Source Of Devastating Colorado Wildfire

Authorities in Colorado were searching for more answers Monday as they investigated what caused the destructive fire that torched scores of homes and displaced residents in the suburbs of Denver last week.

At least two people were missing and more than 1,000 houses and businesses were destroyed or damaged in the fire that blitzed a 10-square-mile area in Boulder County around the towns of Superior and Louisville.

Authorities initially said downed power lines may have caused the fire, which started Thursday, but Boulder County Sheriff Joe Pelle said Sunday there’s an "open and active investigation" into the origin of the flames.

While Pelle provided few details about the investigation, he said that one neighborhood west of the towns is at the center of the probe.
