Mason City Man Sentenced to 11 years in Federal Prison for Illegal Possession of Firearms and Intent to Distribute Meth

Jacob Shafer, 34, from Mason City, Iowa, was sentenced September 12, 2025, in federal court in Sioux City.

Shafer pled guilty on May 7, 2025, to one count of possession with intent to distribute methamphetamine and one count of illegal possession of a firearm. Shafer was previously convicted of possession of methamphetamine with intent to deliver, and trafficking in stolen weapons in Iowa in March of 2022. Both of these convictions prohibit a person from possessing any firearm.

Evidence at the plea and sentencing hearings showed that in March 2024, during the execution of a search warrant at Shafer's home, law enforcement seized the following: four bags of methamphetamine; drug paraphernalia including pipes, bongs, grinders, and baggies; a digital scale; ninety-six .380 caliber Winchester rounds of ammunition; a Ruger LCP, .380 pistol, and a total of 6 rounds of ammunition, which included a round in the chamber; a Smith & Wesson .40 caliber pistol, and a total of 13 rounds of ammunition; an Intratec AB-10, 9mm pistol, and a total of 22 rounds of ammunition in the magazine; and a Rock Island Armory, .45 caliber pistol. Shafer admitted he had plans to distribute the methamphetamine that officers found.

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.

Sentencing was held before United States District Court Judge Leonard T. Strand. Shafer was sentenced to 132 months' imprisonment and will serve a four-year term of supervised release following imprisonment. There is no parole in the federal system. Shafer remains in custody of the United States Marshal until he can be transported to a federal prison.

The case was investigated by the Cerro Gordo County Sheriff's Office, Mason City Police Department, Iowa Division of Criminal Investigations, Bureau of Alcohol, Tobacco, Firearms, and Explosives, and was prosecuted by Assistant United States Attorneys Kevin C. Fletcher and Kraig R. Hamit.
