Sioux Falls Man Sentenced to Over 13 Years in Federal Prison for Methamphetamine Conspiracy

Northeast Radio SD News – South Dakota - A Sioux Falls, South Dakota, man has been sentenced to 160 months (over 13 years) in federal prison after being convicted of Conspiracy to Distribute a Controlled Substance. The sentence was announced by United States Attorney Ron Parsons and handed down by U.S. District Judge Schreier on December 1, 2025.

Alex Lang, 31, was sentenced to 160 months in prison, followed by five years of supervised release. Lang was also ordered to pay a fine and a $100 special assessment to the Federal Crime Victims Fund.

Lang was indicted by a federal grand jury in April 2025 and pleaded guilty to the conspiracy charge on September 9, 2025.

According to investigators, Lang worked with others to distribute multiple pounds of methamphetamine within the Sioux Falls community. The investigation found that Lang obtained the controlled substance from a co-conspirator whom investigators identified as sourcing the methamphetamine from Arizona via the mail. Lang was then responsible for selling the methamphetamine to others. In total, investigators estimate that Lang was accountable for distributing approximately seven pounds of methamphetamine in the community.

The case is part of Operation Take Back America, a nationwide initiative by the Department of Justice aimed at utilizing the full resources of the Department to eliminate cartels and transnational criminal organizations and to protect communities from perpetrators of violent crime. This operation streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).

The case was the result of an investigation conducted by the United States Postal Inspection Service and the Minnehaha County Sheriff’s Office. Assistant U.S. Attorney Mark Hodges prosecuted the case.

Lang was immediately remanded to the custody of the U.S. Marshals Service following the sentencing.
