Waterloo Woman Sentenced to Federal Prison for Lying While Buying Four Guns

A woman who bought four guns over six months and lied about her drug use was sentenced June 17, 2026, to a year in federal prison.

Sydnie Mahoney, age 28, from Waterloo, Iowa, received the prison term after a January 23, 2026, guilty plea to making a false statement during the purchase of a firearm.

Information at sentencing showed that between March 2023 and September 2023, Mahoney bought four guns on four separate occasions from a gun dealer in Cedar Falls, Iowa. During each purchase, Mahoney signed a form on which she indicated she was not an unlawful user of controlled substances, including marijuana. Mahoney was a marijuana user at the time of each purchase. During two of the purchases, Mahoney was accompanied by Torion Byrd, her boyfriend.

Later, police officers found Byrd driving a car with another man who was wanted on an outstanding arrest warrant. Officers searched the car and found one of the guns Mahoney had purchased in the glove box. Byrd's DNA was found on the gun, which had an extended magazine. Byrd was a convicted felon. Byrd was sentenced to over three years in federal prison.

Mahoney was sentenced in Cedar Rapids by United States District Court Chief Judge C.J. Williams. Mahoney was sentenced to 12 months and a day in federal prison. She must also serve a three-year term of supervised release after the prison term. There is no parole in the federal system.

This case is part of Operation Take Back America a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime.

Mahoney was released on the bond previously set and is to surrender to the United States Marshal on July 20, 2026.

The case was prosecuted by Assistant United States Attorney Anthony Morfitt and investigated by a Federal Task Force composed of the Waterloo Police Department, Federal Bureau of Investigation, and Bureau of Alcohol, Tobacco, and Firearms assisted by the Black Hawk County Sheriff's Office and Cedar Falls Police Department.
