Davenport man sentenced to federal prison for gun, ammunition charges

A Davenport man was sentenced Wednesday, Aug. 12, to 46 months – a little less than four years – in federal prison for possessing a firearm and ammunition as a felon and 18 months in federal prison for revocation of his supervised release, a news release says.

According to public court documents and evidence presented at sentencing, Terry Markey Miller, 44, possessed a firearm and ammunition at his Davenport residence. The items were located during a search in January 2025. Miller is prohibited from possessing firearms because he is a felon. Miller was on federal supervised release and had been released from prison 10 days prior to his arrest.

At sentencing, the court also revoked Miller’s supervised release. In 2010, Miller was sentenced to a 30-year prison term for conspiracy to distribute cocaine base in the United States District Court for the Southern District of Iowa. His sentence was commuted and he was released from prison in January 2025.

After completing his term of imprisonment, Miller will be required to serve a three-year term of supervised release. There is no parole in the federal system.

United States Attorney David C. Waterman of the Southern District of Iowa made the announcement. The Davenport Police Department investigated the case.

Project Safe Neighborhoods (PSN) is the Department of Justice’s nationwide initiative that brings federal, state, local, and tribal law enforcement, prosecutors, and other public safety partners together to coordinate efforts to combat violent crime and make communities safe. Coordinated by U.S. Attorneys’ offices in each of the 94 federal districts, PSN is tailored to particular communities to strategically address specific violent crime and public safety challenges.

As a key component of Operation Take Back America, PSN serves a central role in the department’s commitment to make our country safe. PSN emphasizes three core principles: rapid federal response to violent crime and criminal offenders; strong, strategic partnerships among law enforcement at all levels; and accountability and deterrence through the prosecution of the most serious, readily provable offenses and other strategies.

These efforts complement and strengthen President Trump’s Homeland Security Task Forces, ensuring a comprehensive federal response to the most pressing public safety issues facing communities. For more information about Project Safe Neighborhoods, visit here.
