BANGOR, Maine: A former Portland man was sentenced today in U.S. District Court in Bangor for being a felon in possession of a firearm. The charges stemmed from an August 2021 standoff with the Brewer Police Department.

U.S. District Judge Lance E. Walker sentenced Patrick Mullen, 52, to 37 months in prison and three years of supervised release. Mullen pleaded guilty on February 10, 2022.

According to court records, on August 28, 2021, the Brewer Police Department was called to the Brewer Walmart parking lot due to a reported disturbance. Mullen was located in the lot in his truck, and a check of his information showed that he had three outstanding warrants. In addition, he was observed in his truck holding a firearm. After an hours-long standoff, he was arrested. He is prohibited from possessing firearms due to a 2017 conviction in the Washington County Unified Court for domestic violence criminal threatening with a dangerous weapon.

The Brewer, Holden and Bangor police departments; Penobscot County Sheriff’s Office; Maine State Police; and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) investigated the case. The Penobscot County District Attorney’s Office also assisted with the case.

Project Safe Neighborhoods: 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.
