BOULDER, Colo. (AP) - The Denver Post is reporting that authorities are investigating whether a fire pit sparked a devastating 10-square-mile wildfire near Boulder.

The Post reports Sunday that criminal charges are possible if investigators determine that the wildfire was started by an untended fire pit. The newspaper attributes the information to a senior law enforcement official familiar with the investigation. The newspaper did not name the official.
      
Boulder Sheriff Joe Pelle previously said investigators initially believed the fire was started by a vehicle that crashed into a propane tank.
      
The wildfire that began Sept. 6 has cost more than $6.7 to fight and destroyed 169 homes, making it one of the most damaging fires in Colorado history.
