ABERDEEN, S.D. — U.S. District Judge Charles Kornmann ordered three men to prison Monday, July 12, for sexually abusing minors.

Receiving the longest sentence was Kevin Lee Farmer, 58, of Agency Village, S.D., who was sentenced to 20 years for abusive sexual contact with a child in 2016 when, using force, he intentionally touched the victim's genitalia and other parts of their body, according to a news release from acting South Dakota U.S. Attorney Dennis Holmes.

The victim was under 12 years old at the time of the abuse. Kornmann also found that Farmer sexually abused other children, although details weren't released.

In another case, Okokipe Jones, 47, was sentenced to almost 17 years in prison for abusive sexual contact with a child. The Sisseton, S.D., man was accused of abusing a victim who was under 12 years old in 2010.

In the third sentencing, David George Derby, 24, was ordered to spend three years in prison for abusive sexual contact with a minor.

Derby was found guilty of engaging in sexual contact in April 2020 with a 17-year-old girl after they both had consumed alcoholic beverages and the victim became intoxicated, court documents said.

All three men, members of the Sisseton Wahpeton Oyate Tribe in northeast South Dakota, were turned over to the U.S. Marshals Service to be taken to prison after the sentencing hearings.
