Sioux Falls Man Sentenced to More Than 4 Years in Federal Prison for Illegal Possession of a Firearm

SIOUX FALLS - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Karen E. Schreier has sentenced a man from Sioux Falls, South Dakota, convicted of Possession of a Firearm by a Prohibited Person. The sentencing took place on September 29, 2025.

Jericho James Ladeaux, 32, was sentenced to four years and three months in federal prison, followed by three years of supervised release, and ordered to pay a $100 special assessment to the Federal Crime Victims Fund. Ladeaux was further ordered to forfeit the firearm and ammunition.

Ladeaux was indicted by a federal grand jury for Possession of a Firearm by a Prohibited Person in April 2025. He pleaded guilty on July 17, 2025.

The conviction stemmed from an incident on January 9, 2025, when law enforcement found Ladeaux driving what they believed to be a stolen vehicle. Law enforcement conducted a traffic stop and arrested Ladeaux, at which time they discovered he was carrying a loaded pistol. Ladeaux is prohibited from possessing firearms and ammunition due to previous felony convictions.

This case was investigated by the Sioux Falls Police Department, the Minnehaha County Sheriff's Office, and the Bureau of Alcohol, Tobacco, Firearms and Explosives. Supervisory Assistant U.S. Attorney Connie Larson prosecuted the case.

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. Operation Take Back America streamlines efforts and resources from the Department's Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN). Through PSN, the District of South Dakota seeks to bring together all levels of law enforcement and the communities they serve to reduce gun violence and make our neighborhoods safer for everyone.

Ladeaux was immediately remanded to the custody of the U.S. Marshals Service.
