Two cousins were charged Wednesday with starting the Arizona Wallow Fire in May, the largest wildfire in that state’s history. Caleb Joshua Malboeuf, 26, and David Wayne Malboeuf, 24, allegedly left a campfire unattended on May 29, which spread into a blaze that lasted for more than a month. The fire destroyed more than three dozen homes and businesses and displaced 100,000 people; fighting it cost $79 million. The cousins allegedly tried to return to their campsite to put out the fire, but the flames and smoke had become too intense. They have been charged with five counts of leaving timber to burn, leaving a fire unattended and unextinguished, and building a campfire without removing all surrounding flammable material. A conviction for each of the charges carries a maximum penalty of six months in prison, a $5,000 bond, or both.
