FORT WORTH, Texas (AP) — Officials say an Arkansas man who was working at a federal medical prison in Texas must serve a year behind bars for molesting a female inmate he was overseeing.

Prosecutors say 39-year-old Matthew McGaugh of Hensley, Arkansas, was sentenced Monday by a federal judge in Fort Worth. McGaugh in July pleaded guilty to sexual abuse of a ward.

McGaugh worked as a case manager at the Carswell Federal Medical Center in Fort Worth. Prosecutors, in a statement , said McGaugh last year engaged in multiple sexual acts with an inmate under his supervision. The indictment says McGaugh forced the prisoner to perform a sex act on him.

The Federal Bureau of Prisons says the duties of a case manager include evaluating the progress of inmates and developing release plans.
