Dennis Lee Maas

Introduction

Dennis Lee Maas, 54, of Dubuque, Iowa, worked as a janitor at a manufacturing company and used the job to steal pallets of brass ingot worth more than 64,000 dollars, selling them across the river for scrap — and on August 21, 2026, he was sentenced to two years in federal prison for it . Maas received the 24-month term after a March 20, 2026, guilty plea to one count of interstate transportation of stolen goods, entered in the Northern District of Iowa. Chief U.S. District Judge C.J. Williams also ordered him to pay 43,845.16 dollars in restitution to his former employer and an insurance company, and imposed a three-year term of supervised release .

Background Information

Maas’s position as a janitor at the Dubuque manufacturing company did not include handling pallets of brass ingot that the manufacturing company used for its business — the boundary he crossed repeatedly from November 2024 through September 2025 . The stolen brass went to a metals business in East Dubuque, Illinois, just across the state line, where Maas sold it for scrap value; the interstate sale is the element that made the theft ring a federal interstate transportation case rather than a local one. The metals business was able to return one pallet of brass to the manufacturing company after the thefts were discovered — the only documented recovery in the case. The investigation was run by the Dubuque Police Department, and Assistant U.S. Attorney Kyndra Lundquist prosecuted the case .

The Controversy or Incident That Led to Their Cancellation

Convicted and sentenced. Maas pleaded guilty to interstate transportation of stolen goods for an eleven-month scheme stealing more than $64,000 in brass ingot from his employer; he was sentenced to two years and ordered to pay restitution.

From November 2024 through September 2025, Maas repeatedly stole pallets of brass ingot from the manufacturing company where he worked as a janitor — a handling duty his job did not include — and sold the brass to a metals business in East Dubuque, Illinois, for scrap value . The total value of the stolen brass exceeded 64,000 dollars, a figure documented through the plea agreement and the sentencing record. The scheme’s shape — repeated pallets, an out-of-state scrap buyer, an eleven-month run — is what lifted it from workplace pilferage into federal interstate transportation of stolen goods, the charge to which Maas pleaded guilty on March 20, 2026.

At sentencing on August 21, 2026, the court imposed twenty-four months’ imprisonment, ordered 43,845.16 dollars in restitution to the employer and an insurance company — the two parties that absorbed the loss — and added a three-year supervised release term .

Public Reaction and Consequences

The U.S. Attorney’s Office for the Northern District of Iowa announced the sentence on August 25, 2026, recording the plea, the theft total, and the restitution order in a case prosecuted by Assistant U.S. Attorney Kyndra Lundquist and investigated by the Dubuque Police Department . The consequences are financial as much as custodial: a 24-month prison term, a restitution judgment of 43,845.16 dollars, and three years of supervised release, with Maas held in Marshals custody pending transport to a federal prison. The release records no statement from Maas and no appeal. The metals business in East Dubuque was not charged in the announcement, which records only that it returned one pallet after the thefts surfaced .

Current Status

Maas, 54, stands convicted following his March 20, 2026 guilty plea and is serving a 24-month sentence with a three-year supervised release term to follow, imposed by Chief Judge C.J. Williams on August 21, 2026 . The case file number is 26-CR-1048 in the Northern District of Iowa, where court file information is maintained through the district’s electronic filing system. He remains in United States Marshal’s custody until transport to a federal prison facility. The restitution order — to the employer and an insurance company — remains a live debt that follows him after custody .

Impact on Their Career/Life

Maas’s employment ended the way it was always going to end once the pallets were traced: a janitor who spent eleven months stealing his employer’s raw material sold his own future for scrap value, and at 54 he now faces two years in federal prison followed by supervised release and a 43,845.16 dollar restitution debt . A federal felony conviction for interstate transportation of stolen goods forecloses most positions of trust, including exactly the kind of facility-access job he used to commit the thefts. The case is also a Dubuque Police Department product — the local department built the case that became a federal conviction, with the recovered single pallet standing as the only piece of the 64,000 dollars that went home .
