The U.S. Court of Appeals for the First Circuit has ruled against Matthew McDonald, who sought to overturn his conviction for using a firearm during a violent crime. The court's decision, issued on August 28, 2026, affects McDonald and his ongoing imprisonment stemming from a series of violent bank and armored car robberies he committed in the 1990s.

This ruling is significant as it addresses the legal standards for convictions involving firearms and violent crimes, particularly in light of recent changes in federal law regarding sentencing enhancements for violent felonies.

Background

Matthew McDonald was convicted in the early 2000s for a series of violent crimes, including armed bank robbery and carjacking. He was part of a group that committed numerous robberies, often using firearms. His criminal activities culminated in a horrific incident in Hudson, New Hampshire, where two armored car guards were murdered during a robbery.

McDonald faced multiple charges, resulting in a life sentence due to the severity of his crimes. Over the years, he filed several motions under 28 U.S.C. § 2255, a federal statute that allows prisoners to challenge their sentences on constitutional grounds. His latest appeal focused on the legality of his gun-use conviction, particularly in light of recent Supreme Court rulings that have impacted how courts interpret violent crime statutes.

The Ruling

The First Circuit Court of Appeals, led by Judge Thompson, ultimately upheld McDonald’s conviction. The court noted that McDonald had failed to demonstrate that the jury's verdict was based solely on an invalid predicate offense. The judges emphasized that the evidence presented at trial clearly showed that McDonald was involved in a conspiracy to commit armed robberies, which justified the jury's finding of guilt regarding the use of a firearm.

The court stated, "The trial evidence showed — and the jury inescapably found — that an 'overarching conspiracy' to rob banks and armored cars 'existed,' given all the proof pointing to 'a common and continuing aim, similar methods of operation, continuity in personnel, and interdependence.'"

Furthermore, the court found that any errors in jury instructions regarding the definition of a violent crime were harmless, as the jury could have reasonably convicted McDonald based on valid predicate offenses.

Impact

This ruling reinforces the legal standards surrounding firearm use in connection with violent crimes. It clarifies that even if one predicate offense is invalidated, a conviction can still stand if there are valid predicates supporting the jury's verdict. This case also illustrates the challenges defendants face when attempting to overturn convictions based on complex legal arguments surrounding jury instructions and predicate offenses.

McDonald’s case may set a precedent for future appeals involving similar circumstances, particularly as courts continue to navigate the implications of recent Supreme Court decisions affecting firearm-related convictions.

What's Next

McDonald may seek further legal recourse, including a potential appeal to the U.S. Supreme Court. However, the court's ruling significantly narrows the grounds for such an appeal, as it firmly establishes the validity of his conviction based on the remaining predicates.
