Great Falls man sentenced to over 10 years in prison on drug charges

GREAT FALLS - A convicted felon from Great Falls who possessed guns and drugs was sentenced today to 128 months in prison to be followed by5 years of supervised release, U.S. Attorney Kurt Alme said.

Michael Shawn O'Neill, 59, pleaded guilty in December 2024 to possession with intent to distribute controlled substances.

Chief U.S. District Judge Brian Morris presided.

The government alleged in court documents that on September 4, 2023, Michael Shawn O'Neill, a convicted felon on state supervision, possessed thousands of fentanyl pills for redistribution, as well as four firearms and some methamphetamine and heroin. The guns and drugs were found during a probation search and the subsequent execution of a search warrant in Great Falls, Montana. On September 14, 2023, O'Neill told interviewing agents that there was no one above him in the Great Falls area. He drove to Spokane to get his supply and he believed he was one step away from the cartel through a third party. He distributed drugs to smaller users who purchased less than 100 pills at a time. He said he just spent $12,000 in Spokane on the drugs found on September 4, 2023,and told agents: "I was moving about 500-800 pills a day, plus an ounce of heroin, plus an ounce of meth - I wasn't moving that much."

The U.S. Attorney's Office prosecuted the case and the investigation was conducted by the ATF, Russell Country Drug Task Force, and Montana Probation and Parole.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the Department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.
