Porcupine Man Sentenced to 10 Years in Federal Prison for Manslaughter

United States Attorney Ron Parsons announced that a Porcupine, South Dakota, man convicted of Voluntary Manslaughter was sentenced by Jeffrey L. Viken, U.S. District Judge.

Lawrence Pourier, a/k/a Larry Pourier, age 52, was sentenced on September 4, 2020, to 10 years in federal prison, followed by 3 years of supervised release, and was ordered to pay a $100 special assessment to the Federal Crime Victims Fund.

The conviction stems from Pourier repeatedly striking another man in the head with a pipe-like object, causing his death, in January 2020 near Porcupine.

The investigation was conducted by the Federal Bureau of Investigation and the Oglala Sioux Tribe Department of Public Safety.  Assistant U.S. Attorney Benjamin Patterson prosecuted the case.

Pourier was immediately remanded to the custody of the U.S. Marshals Service to being serving his sentence.
