Authorities say they don't know if they'll file charges in either of the two wildfires in Colorado.
The one near Boulder, which destroyed more than 160 homes, is now contained. Investigators believe it was sparked by a fire that a resident had set days earlier in a fire pit. The resident is a longtime volunteer firefighter.
A fire near Loveland, which has destroyed two homes, was started by a resident burning a brush pile.
The Boulder fire, which started on Labor Day, drove thousands of people from their homes when it swept through canyons and up steep mountainsides. At least 2,000 people have been cleared to return.
The one near Loveland is now 20 to 25 percent contained.
