In August, 2014, Kelley was arrested on an animal cruelty charge, a misdemeanor offense, in El Paso County, Colorado, according to the El Paso County Sheriff's Office. A witness said Kelley punched a dog with a closed fist, grabbed it by the neck and dragged the animal, officials said. Kelley, who was living in a Colorado Springs RV park at the time, denied the account. He was issued a summons but did not spend any time in jail for the offense.
