DES MOINES, Iowa – Matthew Allen Sumpter, 39, of Marshalltown, is headed for a lengthy stay in federal prison after being sentenced to 17 years for a cocktail of serious federal charges. Sumpter received the sentence on September 12, 2025, after pleading guilty to possession with intent to distribute methamphetamine and possession of a firearm in furtherance of drug trafficking. The bust reveals a dangerous operator flooding the Marshalltown area with poison.
The case unfolded in October 2024 when law enforcement discovered Sumpter in possession of nearly a pound of methamphetamine – enough to wreck countless lives. Alongside the drugs, officers found a scale for weighing the product, a stash of cash, and, crucially, a loaded handgun. This wasn’t a simple possession case; investigators quickly determined Sumpter was responsible for distributing multiple pounds of methamphetamine throughout Marshalltown, turning a profit off the misery of others.
What’s particularly damning is Sumpter’s extensive criminal history. This isn’t his first rodeo. Court records show a litany of prior felony convictions, including being a prohibited person in possession of a firearm – a clear indication he disregarded the law even before this incident. Adding to the list are convictions for harassment, domestic abuse assault by strangulation, and multiple counts of eluding law enforcement. Sumpter clearly has a pattern of violent and reckless behavior, and the court has finally responded with a sentence that reflects the gravity of his crimes.
U.S. Attorney Richard D. Westphal of the Southern District of Iowa announced the sentencing, emphasizing the commitment to dismantling drug trafficking operations and removing dangerous individuals from the streets. “This sentence sends a clear message,” Westphal stated, “that those who peddle poison and endanger our communities will be held accountable to the fullest extent of the law.” The investigation was a collaborative effort between the Mid-Iowa Drug Task Force and the Marshall County Sheriff’s Office, demonstrating the power of coordinated law enforcement.
Sumpter’s prison sentence isn’t the end of the line. Upon release, he will be subject to a five-year term of supervised release – a period where his movements and activities will be closely monitored. It’s crucial to remember there’s no parole in the federal system, meaning Sumpter will serve the entirety of his 17-year sentence. This is a long-overdue reckoning for a repeat offender who showed a blatant disregard for the safety and well-being of the Marshalltown community.
