SIOUX CITY — A Dakota City man has been sentenced to more than three years in federal prison after pleading guilty to conspiracy to distribute methamphetamine, according to the U.S. Attorney’s Office — Northern District of Iowa.

Tyler Tinken, 37, was sentenced on Monday.

He pleaded guilty to conspiracy to distribute meth, distribution of meth and possession with intent to distribute meth.

Evidence showed that from July 2019 through Nov. 14, 2019, Tinken was involved in a conspiracy that distributed meth in the Humboldt and Sac County areas.

On multiple occasions in September and October 2019, Tinken distributed just over a pound of pure meth to individuals cooperating with law enforcement.

During a search of Tinken’s vehicle and residence in November 2019, law enforcement seized over 650 grams of pure methamphetamine that Tinken intended to distribute to others.

Tinken was sentenced in Sioux City by U.S. District Court Chief Judge Leonard T. Strand. Tinken was sentenced to 47 months’ imprisonment. He must also serve a three-year term of supervised release after the prison term. There is no parole in the federal system. Tinken was released on the bond previously set and is to surrender to the Bureau of Prisons on a date yet to be set.

The case was prosecuted by Assistant United States Attorney Shawn S. Wehde and investigated by Tri-State Drug Task Force based in Sioux City, that consists of law enforcement personnel from the Drug Enforcement Administration; Sioux City Police Department; Homeland Security Investigations; Woodbury County Sheriff’s Office; South Sioux City, Nebraska, Police Department; Nebraska State Patrol; Iowa National Guard; Iowa Division of Narcotics Enforcement; United States Marshals Service; South Dakota Division of Criminal Investigation; and Woodbury County Attorney’s Office.
