Manson Man Pleads Guilty to Conspiring to Distribute Methamphetamine

A man who conspired to distribute methamphetamine pled guilty on July 15, 2026, in federal court in Sioux City.

Tanner Thomas Rokes, age 36, from Manson, Iowa, was convicted of one count of conspiracy to distribute 500 grams or more of methamphetamine.

At the plea hearing, Rokes admitted that from 2021 to July, 2025, in Webster County, Iowa, he was involved in distributing over five pounds of methamphetamine. In May 2025 law enforcement officers received information that Rokes was a pound-level distributor of methamphetamine. Law enforcement officers then made multiple controlled purchases of methamphetamine from Rokes.

On July 15, 2025, officers stopped Rokes while he was driving without a valid driver's license. Prior to stopping his car, officers observed Rokes throw 80 grams of methamphetamine out the car's window. Rokes ultimately stopped the car and officers found additional methamphetamine inside the car. Officers also found the discarded methamphetamine.

Sentencing before United States District Court Judge Leonard T. Strand will be set after a presentence report is prepared. Rokes remains free on bond previously set. Rokes faces a mandatory minimum sentence of ten years' and up to life imprisonment, a $10,000,000 fine, and at least five years of supervised release.

The case is being prosecuted by Assistant United States Attorney Patrick T. Greenwood and was investigated by the Iowa Division of Narcotics Enforcement, the Fort Dodge Police Department, the Webster County Sheriff's Office and the Iowa State Patrol.
