Reports obtained by KGUN9 have confirmed that Dennis Dickey admitted to starting the Sawmill Fire while target shooting.
Border Patrol has confirmed that Dickey is an agent and was off-duty at the time the fire sparked.
According to reports, Dickey admitted to a Pima County Sheriff's deputy that "he was one of the individuals who reported the fire and that he had been the one out target shooting which initially started the brush fire."
He told the deputy "he was target shooting Tannerite, which was an explosive powder easily purchased which could be detonated by a high velocity rifle round and was commonly used in target shooting."
