Johanna Grace, aged 34 pleaded guilty to felonies in federal court in July. Prosecutors say Grace coordinated with associates outside the prison “multiple times” to bring contraband into the facility.

An informant outside the prison alerted authorities to her misconduct, according to U.S. Attorney Gregory Haanstad. Grace shared internal law enforcement reports with her associates, he said, who confronted the informant. Grace admitted to obstructing justice, Haanstad said.

“Today’s sentence is the direct result of an individual who abused her authority and violated the trust of the residents she was entrusted to serve and protect,” Haanstad said in a statement.
