Lowman was prohibited from possessing guns due to a felony drug conviction in 2004.

A man who conspired to distribute methamphetamine while he illegally possessed firearms was sentenced March 3, 2022, to more than 11 years in federal prison.

Lucas Lowman, 39, from Mason City, Iowa, received the prison term after an October 7, 2021, guilty plea of conspiracy to distribute methamphetamine and prohibited person in possession of firearms.  Lowman was previously convicted of Possession of a Controlled Substance-3rd or Subsequent Offense, in the Iowa District Court for Cerro Gordo County, in 2004.  This conviction prohibits a person in Iowa from possessing firearms.

Evidence at the plea and sentencing hearings showed that between October 2019 and March 2021, Lowman possessed a number of guns, including a 12-gauge shotgun. Lowman utilized a gun to assault another, and between April 2019 and November 2019, Lowman and others conspired to distribute methamphetamine.

Lowman was sentenced in Sioux City by United States District Court Chief Judge Leonard T. Strand.  Lowman was sentenced to 135 months’ imprisonment.  He must also serve a 5-year term of supervised release after the prison term.  There is no parole in the federal system.  Lowman is being held in the United States Marshal’s custody until he can be transported to a federal prison.

The case was prosecuted by Assistant United States Attorney Patrick T. Greenwood and investigated by the Iowa Division of Narcotics Enforcement, Mason City Police Department, Iowa State Patrol, Cerro Gordo County Sheriff’s Office, North Central Iowa Drug Task Force, and Iowa DCI Laboratory.
