PIERRE - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Eric C. Schulte has sentenced a Pierre, South Dakota woman convicted of Conspiracy to Distribute a Controlled Substance. The sentencing took place on May 14, 2025.

Heather Stahlhoefer, age 38, was sentenced to 18 years in federal prison, followed by five years of supervised release and ordered to pay a $1000 fine, as well as a $100 special assessment to the Federal Crime Victims Fund.

Stahlhoefer was indicted by a federal grand jury in September 2024. She pleaded guilty on March 10, 2025.

This conviction stemmed from a drug distribution conspiracy beginning in June 2023 and continuing until September 2024. Heather Stahlhoefer and co-defendant Misty Stahlhoefer were the source of supply to several other individuals in the Pierre area. The Stahlhoefers would acquire up to 1 pound of methamphetamine per trip to be further distributed by themselves and others including Whitney Marrowbone, Wendy Mealer, Brent Larvie, and David Rinehart. The conspiracy involved between 10,000 and 30,000 kilograms of converted drug weight, including 550 grams of pure methamphetamine that was recovered during a traffic stop of Heather Stahlhoefer.

Misty Stahlhoefer is scheduled to be sentenced July 14, 2025. Marrowbone, Mealer, Larvie and Reinhart were previously sentenced on May 5, 2025. Marrowbone was sentenced to 11 years in federal prison; Mealer was sentenced to six years in federal prison; Larvie was sentenced to four years and six months in federal prison; and Rinehart was sentenced to two years in federal prison.

This case was investigated by the FBI Northern Plains Safe Trails Drug Enforcement Task Force, the Pierre Police Department, the Chamberlain Police Department, and the Lyman County Sheriff’s Office. The case was prosecuted by Assistant United States Attorney Meghan Dilges.

Stahlhoefer was immediately remanded to the custody of the U.S. Marshals Service.
