The Park County Sheriff has confirmed that the 403 Fire, which has burned over 1,500 acres, was human-caused.   

The 403 fire was first reported on Thursday, March 30th. Several residents in Park and Teller counties were forced out of their homes for mandatory evacuations.   

According to Park County Sheriff Tom McGraw, someone in Park County dumped out ash from a fireplace into the backyard of their home. That triggered the fire which quickly grew out of control.  

Law enforcement plans on pursuing as many charges as possible against the individual.  

The fire remains at 1,518 acres and is 60 percent contained.
