Extensive fire in Superior and Louisville, Colorado, USA

Pelle also said that authorities had received a number of tips about the potential causes of the fires and that a search warrant was executed at a property. He did not say where the search occurred. He also said that no downed power lines, which were thought to have been a possible cause of the fire, have been found.

He said an investigation into the origin of the fires was ongoing.

Approximately 991 homes and other structures in Louisville, Superior and Marshall were destroyed and 127 were damaged, Pelle said.

Snow blanketed metro Denver Friday night putting out hotspots and preventing further spread of the Marshall fire in Boulder County.

Communities in the affected burn areas received as much as 10 inches and frigid temperatures.

But now many people whose homes didn’t burn are without gas and electricity in freezing temperatures expected to stick around through the weekend.
