Porcupine Man Sentenced to Twenty Years in Federal Prison

Acting United States Attorney Dennis R. Holmes announced that a Porcupine, South Dakota, man convicted of Abusive Sexual Contact was sentenced on August 2, 2021, by Judge Jeffrey L. Viken, U.S. District Court.

Leonard Martin Brings Plenty, age 73, was sentenced to 20 years in federal prison, followed by five years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

Brings Plenty was indicted by a federal grand jury in June 2019.  He pleaded guilty on December 9, 2020.

In 2016, Brings Plenty sexually molested two young females, ages four and six, at his residence in Porcupine.

This case was investigated by the Federal Bureau of Investigation.  Assistant U.S. Attorney Megan Poppen prosecuted the case.

Brings Plenty was immediately turned over to the custody of the U.S. Marshals Service.
