Sioux City Man Sentenced to More Than 12 Years in Federal Prison for Meth Convictions

A man who conspired to distribute methamphetamine was sentenced on March 28, 2025, in federal court in Sioux City.

Blake Putnam, 39, from Sioux City, Iowa, pled guilty on December 3, 2024, to one count of conspiring to distribute methamphetamine and two counts of possession with intent to distribute methamphetamine.

Evidence at the plea and sentencing hearings showed that from January 2021 through March 2024, Putnam and others conspired to distribute 4500 grams (nearly 10 pounds) of methamphetamine in the Sioux City area.  On February 5, 2024, law enforcement attempted to conduct a traffic stop on the vehicle Putnam was driving.  Putnam attempted to elude law enforcement at high speeds and was apprehended when his vehicle blew a tire and stopped after hitting a curb.  During the eluding attempt, Putnam was observed by a concerned citizen throwing packages out of his vehicle attempting to discard drug evidence.  In the area identified, agents located and seized nearly one pound of methamphetamine in two packages.  Agents also seized an eight-ball of methamphetamine, and 50 Adderall pills from defendant’s person.  On March 5, 2024, after obtaining a search warrant, law enforcement seized approximately one pound of meth in one bag and about one ounce of meth in another bag from a backpack in a rental storage unit leased by Putnam in Sioux City, Iowa.  Putnam brought this backpack to the storage unit on or about March 5, 2024, as evidenced by video recordings at the storage unit business. 

Sentencing was held before United States District Court Judge Leonard T. Strand.  Putnam was sentenced to 151 months’ imprisonment and must serve a five-year term of supervised release following the imprisonment.  There is no parole in the federal system.  Putnam remains in custody of the United States Marshal until he can be transported to a federal prison.  

The case was prosecuted by Assistant United States Attorney Shawn S. Wehde and was investigated by the Tri-State Drug Task Force based in Sioux City, Iowa, that consists of law enforcement personnel from the Drug Enforcement Administration; Sioux City, Iowa, 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, with assistance of Iowa State Patrol.
