Rapid City Woman Sentenced to 25 Years in Federal Prison for Distribution of Fentanyl

RAPID CITY - United States Attorney Alison J. Ramsdell announced today that U.S. District Camela C. Theeler has sentenced a Rapid City, South Dakota, woman convicted of Conspiracy to Distribute a Controlled Substance. The sentencing took place on October 28, 2024.

Kaylonie Goff, 30, was sentenced to 25 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. Goff was also ordered to pay $5,013.18 in restitution to the family of an overdose victim.

Goff was indicted for Distribution of a Controlled Substance Resulting in Death and two counts of Conspiracy to Distribute a Controlled Substance by a federal grand jury in September of 2023. She pleaded guilty on August 13, 2024.

The conviction stems from Goff and others distributing large quantities of fentanyl and heroin in the Rapid City area between 2021 and 2023. A pill Goff sold led to the overdose death of another person. In sentencing Goff, Judge Theeler focused on the deadly risks of distributing fentanyl and the fact every time Goff sold fentanyl, she was putting others at risk. The judge further found Goff's significant role in the conspiracy and her attempts to obstruct the investigation justified a sentence of 25 years in prison.

This case was investigated by the Unified Narcotics Enforcement Team, which is a local drug task force comprised of law enforcement from the Pennington County Sheriff's Office, Rapid City Police Department, South Dakota Division of Criminal Investigation, South Dakota Highway Patrol, and the South Dakota National Guard. Assistant U.S. Attorney Anna Lindrooth prosecuted the case.

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