U.S. District Judge Karen E. Schreier has handed down the punishment to a Pine Ridge, South Dakota, man convicted of Assault with a Dangerous Weapon. Kristopher Kerbaugh, Sr., 36, was sentenced to a total of two years and nine months in federal prison, followed by three years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund. Kerbaugh was indicted for Assault with a Dangerous Weapon and Assault Resulting in Substantial Bodily Injury to an Intimate Partner by a federal grand jury in May of 2024. He pleaded guilty on July 15, 2024. The conviction stems from Kerbaugh stabbing the victim, his wife of ten years. Kerbaugh, who at the time was intoxicated, became angry with the victim while accusing her of infidelity and stabbed her three times with a pocketknife. He also beat her. After stabbing her, he attempted to cover her wounds with duct tape. A third party called the police, and the victim was airlifted to the hospital for treatment of her injuries. In sentencing Kerbaugh, District Judge Schreier stated this was one of the more serious assaults she had seen between a husband and wife. This matter was prosecuted by the U.S. Attorney’s Office because the Major Crimes Act, a federal statute, mandates that certain violent crimes alleged to have occurred in Indian Country be prosecuted in Federal court as opposed to State court. This case was investigated by the Oglala Sioux Tribe Department of Public Safety. Assistant U.S. Attorney Anna Lindrooth prosecuted the case.
