Dewey Dean Butterfly Pleads Guilty in U.S. Federal Cour
The United States Attorney's Office announced that during a federal court session in Great Falls, on May 8, 2012, before U.S. District Judge Sam E. Haddon, DEWEY DEAN BUTTERFLY, a 39-year-old resident of Browning, pled guilty to assault resulting in serious bodily injury. Sentencing has been set for August 20, 2012.
In an Offer of Proof filed by Assistant U.S. Attorney Laura B. Weiss, the government stated it would have proved at trial the following:
BUTTERFLY is an enrolled member of the Blackfeet Indian Tribe. In the late evening hours of September 9, 2011, the victim was assaulted in a trailer by BUTTERFLY within the exterior boundaries of the Blackfeet Indian Reservation.
BUTTERFLY repeatedly punched her face and head, stomped on her legs, and choked her to the point of unconsciousness. The victim was ultimately able to escape the next morning when friends came to the trailer to check on her.
The victim was transported to the hospital where she was prescribed potent pain medication as a result of the extreme pain and had injuries resulting in what the treating physician described as protracted and obvious disfigurement to her face. The victim also lost consciousness as a result of the assault.
BUTTERFLY faces possible penalties of 10 years in prison, a $250,000 fine and 3 years supervised release.
The investigation was conducted by the Federal Bureau of Investigation.
