Inmate at United States Penitentiary Pleads Guilty to Assaulting Another Inmate


SCRANTON, PA — The United States Attorney’s Office for the Middle District of Pennsylvania announced that Isiah Robinson, age 36, formerly of Maryland, and an inmate at the United States Penitentiary, Canaan, Pennsylvania, pleaded guilty on February 23, 2023, before U.S. District Court Judge Malachy E. Mannion, to the charge of assault with a dangerous weapon.

According to United States Attorney Gerard M.
