Clarkston Woman Sentenced to 5 Years in Prison for Role in Overdose Death

Spokane, Washington - First Assistant United States Attorney Pete Serrano announced on March 31, 2026, that Shannon Louise Grove, age 53, was sentenced on fentanyl distribution charges which resulted in an overdose death. United States District Judge Rebecca L. Pennell sentenced Grove to 5 years in federal prison, to be followed by 6 years of supervised release.

Based on court documents and arguments presented through the pendency of the case, Grove was a longtime drug distributor in the Lewiston, Idaho and Clarkston, Washington area. She had previously been convicted in 2015 in Asotin County, Washington of Possession of Methamphetamine with the Intent to Deliver, as well as a conviction in Nez Perce County, Idaho of Possession of Methamphetamine. In October 2024, Grove distributed fentanyl to a Lewiston man, which ultimately resulted in his death. Phone records and other data confirmed Grove's involvement in the distribution. Based on that conduct, Grove was indicted by a Grand Jury on June 4, 2025. She pled guilty on December 30, 2025.

"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."

"For years, the defendant helped fuel the addiction crisis, and sadly, that cycle ended in tragedy," said Special Agent in Charge Robert Bohls of the Salt Lake City FBI. "The FBI and our partners will hold accountable those who profit from addictions and cause harm in our communities."

This case was investigated by the FBI Salt Lake City Field Office, Lewiston Resident Agency; Lewiston Police Department; and the Quad Cities Drug Task Force. The Quad Cities Drug Task Force is a multi-jurisdiction task force involving numerous law enforcement agencies including the Lewiston Idaho Police Department, Clarkston Washington Police Department, and the Whitman County Sheriff's Office. This case was prosecuted by Assistant United States Attorney Rebecca R. Perez.
