Shannon Louise Grove, age 53, was sentenced on March 31 to five years in federal prison for distributing fentanyl that resulted in an overdose death, according to First Assistant United States Attorney Pete Serrano. United States District Judge Rebecca L. Pennell also ordered Grove to serve six years of supervised release following her prison term.
Grove’s sentencing follows her guilty plea on December 30, 2025, after she was indicted by a Grand Jury on June 4, 2025. The case stems from an incident in October 2024 when Grove distributed fentanyl to a Lewiston man who later died as a result. Investigators used phone records and other data to confirm her involvement.
Court documents indicate that Grove had been a longtime drug distributor in the Lewiston, Idaho and Clarkston, Washington area. She had prior convictions related to methamphetamine possession with intent to deliver both in Asotin County, Washington and Nez Perce County, Idaho.
“Fighting the scourge of fentanyl is a priority for the Department of Justice and for the United States Attorney’s Office for the Eastern District of Washington,” stated Serrano. “This case embodies the devastating impact illicit fentanyl has on individuals, families, and communities. Our deepest sympathies are with the victim and his family, as well as with all others who have lost loved ones due to fentanyl or other controlled substances. We commend the work of our law enforcement partners who work tirelessly to prevent the introduction of these substances into this district.”
Special Agent in Charge Robert Bohls of the Salt Lake City FBI said: “For years, the defendant helped fuel the addiction crisis, and sadly, that cycle ended in tragedy. The FBI and our partners will hold accountable those who profit from addictions and cause harm in our communities.”
The investigation involved multiple agencies including the FBI Salt Lake City Field Office (Lewiston Resident Agency), Lewiston Police Department, Quad Cities Drug Task Force—which includes several local law enforcement departments—and was prosecuted by Assistant United States Attorney Rebecca R. Perez.
