A federal grand jury has indicted Donald Hinley, 53, an inmate at the United States Penitentiary Canaan in northeastern Pennsylvania, on charges that he assaulted a prison official and possessed a makeshift weapon built from plastic with two razor blades fixed to one end, the U.S. Attorney's Office for the Middle District of Pennsylvania announced on November 13.

According to U.S. Attorney Brian D. Miller, the indictment alleges that on April 7, 2026, Hinley assaulted a U.S. Penitentiary Canaan official while that official was engaged in their official duties. The indictment also alleges that on the same date Hinley possessed a weapon measuring 4½ inches, made from plastic with two razor blades affixed to one end.
An indictment is an allegation only. Hinley is presumed innocent of both charges unless and until he is found guilty in court, the Justice Department stressed in its announcement — a point that governs everything reported here: prosecutors have not yet had to prove any part of this case at trial.

What prosecutors did — and did not — say
The Justice Department's announcement does not identify the prison official who was allegedly assaulted, does not describe any injuries, and does not say whether the alleged weapon was used in the alleged assault. Those gaps matter: at the indictment stage the government is setting out what it intends to prove, and the specific facts behind the charges remain subject to the federal court process.
The case was investigated by the Federal Bureau of Prisons' Special Investigative Service — the internal investigations arm of the prison system — together with the FBI Philadelphia Field Office's Capital Area Resident Agency, the U.S. Attorney's Office said. Assistant U.S. Attorney Anthony R. Williamson is prosecuting the case.
The prison and the law behind the charges
USP Canaan is a high-security federal penitentiary in northeastern Pennsylvania, administered by the Federal Bureau of Prisons, and cases arising inside it are prosecuted in the Middle District of Pennsylvania, whose U.S. Attorney's Office is based in Scranton. Assaulting a federal officer and possessing a weapon as an inmate are both federal crimes, separate from any internal prison discipline.
The maximum penalty under federal law for the offences charged is 13 years of imprisonment, followed by a term of supervised release, and a fine, the Justice Department said. If Hinley is convicted, the actual sentence would be imposed by a judge after consideration of the applicable federal sentencing statutes and the Federal Sentencing Guidelines — the maximum is a ceiling set by Congress, not a prediction of the sentence in this case.
Inside a high-security penitentiary, an improvised sharp weapon is treated as a serious security threat to staff and other inmates alike — which is why alleged possession alone, even without proof it was used, is charged as its own federal offence alongside the alleged assault.
What happens next
The indictment, announced November 13, moves the case into open federal court in the Middle District of Pennsylvania: Hinley will be arraigned, enter a plea, and the case will proceed toward trial or a negotiated resolution, with court dates to be set by the court. The U.S. Attorney's Office announcement gave no arraignment date. Until a verdict or a plea, the charges remain exactly what the Justice Department says they are — allegations.
