DES MOINES, Iowa – Another dealer off the streets. Matthew Allen Sumpter, 39, of Marshalltown, Iowa, will spend the next 17 years in federal prison after being convicted of possessing methamphetamine with intent to distribute and illegally carrying a loaded firearm while doing so. The sentence, handed down September 12, 2025, sends a clear message: Iowa isn’t a safe haven for pushing poison.
The bust went down in October 2024, when authorities discovered Sumpter stashed with nearly a pound of methamphetamine, a scale for weighing the product, a wad of cash, and a fully loaded handgun. This wasn’t a small-time operation. Court documents reveal Sumpter was responsible for flooding the Marshalltown area with multiple pounds of the highly addictive drug. He wasn’t just holding; he was moving, and profiting.
This wasn’t Sumpter’s first rodeo with the law, either. The 39-year-old has a rap sheet stretching back years, including prior felony convictions for being a prohibited person in possession of a firearm, harassment, domestic abuse assault by strangulation, and a string of eluding convictions – proving he’s consistently willing to endanger the public to avoid consequences. The system clearly failed to deter him before now.
U.S. Attorney Richard D. Westphal of the Southern District of Iowa announced the sentencing, emphasizing the collaborative effort that brought Sumpter down. The Mid-Iowa Drug Task Force and the Marshall County Sheriff’s Office spearheaded the investigation, demonstrating what can be achieved when law enforcement agencies work together. But investigations only go so far; it’s the courtroom that delivers justice.
Sumpter won’t be eligible for parole. After serving his 17-year sentence, he’ll be subjected to a five-year term of supervised release – a period where his movements will be monitored, and he’ll be held accountable for any further transgressions. This case is part of Project Safe Neighborhoods (PSN), a federal program aimed at reducing violent crime and gun violence by uniting law enforcement and communities.
PSN isn’t just about arrests and convictions; it’s about building trust, supporting community organizations, and strategically targeting the most dangerous offenders.

For now, though, the streets of Marshalltown are a little safer with Matthew Allen Sumpter behind bars.
