Federal Inmate Sentenced to Nearly 3 Years for Assaulting Prison Guard

MADISON, WIS. - Chadwick M. Elgersma, Acting United States Attorney for the Western District of Wisconsin, announced that Demetrius Brown, 47, an inmate at the Federal Correctional Institutional in Oxford, Wisconsin, was sentenced late last week by U.S. District Judge William M. Conley to 33 months in federal prison for physically assaulting a prison guard. Brown's sentence will be served consecutive to the sentence he is already serving for drug trafficking. Brown pleaded guilty to the assault charge on June 9, 2025.

On August 24, 2024, Brown attacked a prison guard after the guard found an item of contraband in Brown's cell. The guard suffered minor injuries.

At sentencing, Judge Conley found it troubling that in addition to causing injury to the guard, Brown's conduct jeopardized the safety of other staff who responded to the assault. Judge Conley also expressed disappointment that Brown appeared to lack insight into his violent behavior.

The charge against Brown was the result of an investigation conducted by the Federal Bureau of Investigation and the Federal Bureau of Prisons. Assistant U.S. Attorney Steven Ayala prosecuted this case.
