Judge Sentences Minneapolis Felon to Federal Prison

Chief U.S. District Judge Eric C. Tostrud sentenced Casey Jemar Davis to 168 months in federal prison for being a felon in possession of a firearm. The court imposed an additional 24 months of incarceration for violating the terms of Davis' federal supervised release.

Why it matters

The sentencing addresses the illegal possession of a firearm modified to function as a machinegun. Davis was already serving a 294-month state prison sentence for his involvement in a deadly shooting in a Minneapolis parking lot.

Davis was sentenced to a total of 192 months in federal prison following his February 2025 arrest in St. Paul. This federal term follows a January 2026 state sentence of 294 months for murder and assault.

The details

Police recovered over 20 casings and two firearms, including a .40-caliber Glock with a machinegun conversion device, after the July 2022 shooting. The device allowed the weapon to fire in fully automatic mode with a single trigger pull.

June 2018: Davis received a prior federal firearms-related conviction.
July 28, 2022: Davis shot and killed one person in Minneapolis.
January 9, 2024: Co-defendant Cleveland Longmire was sentenced to prison.

Legal Context

The prosecution of individuals using illegal conversion devices aligns with the National Firearms Act's machinegun restrictions. This case marks a continuation of federal enforcement efforts targeting the proliferation of modified automatic weapons in urban crime.

The sentencing of a dangerous offender helps ensure public safety for Minneapolis residents and local businesses. Authorities continue to monitor the impact of illegal firearm modifications on local violent crime rates.

The takeaway

Illegal conversion devices that transform standard firearms into fully automatic weapons carry severe federal sentencing consequences. Owners and possessors of such prohibited modifications face mandatory prison time regardless of other state-level criminal convictions.
