United States Attorney Ron Parsons announced that a Gettysburg, South Dakota, man convicted of Assault with a Dangerous Weapon was sentenced on September 4, 2018, by U.S. District Judge Roberto A. Lange.
Christopher Arpan, age 52, was sentenced to 30 months in federal prison, 2 years of supervised release, and a special assessment to the Federal Crime Victims Fund in the amount of $100.
Arpan was indicted by a federal grand jury on Nov. 14, 2017. He pled guilty on June 12, 2018.
The conviction stems from an incident that occurred on Aug. 24, 2017. Cheyenne River Sioux Tribe law enforcement was dispatched to a house in Eagle Butte, South Dakota, for a report of an individual bleeding from a head wound. Arpan had assaulted the individual by beating him about his head with a wooden cane; the beating caused serious bodily harm to the individual including 5 wounds to his head that required multiple staples to close.
This case was investigated by the Cheyenne River Sioux Tribe Law Enforcement Services. Assistant U.S. Attorney Meghan N. Dilges prosecuted the case.
Arpan was immediately turned over to the custody of the U.S. Marshals Service.
