DEER LODGE — An attempted escape from the Powell County jail was thwarted Friday evening by a quick-thinking detention officer.
Sheriff Gavin Roselles said. “At 9 p.m. inmate Calvin J. Mack, 25, was in the common housing unit when he grabbed jail-cell door keys from the detention officer. There was a struggle during which the officer sustained minor injuries; but with quick thinking she was able to secure the facility and acted according to policy. In a few minutes officers removed Mack from the cell block and placed him in a holding cell without further incident. At no time was the public in danger.”
Mack was originally sentenced in Yellowstone County in 2018 to the Department of Corrections for attempted robbery, and was on parole being supervised by the Great Falls Probation and Parole Office. He was being held on a warrant at the time of the incident.

A joint investigation by Powell and Gallatin County officials resulted in Mack’s arrest on August 23 when a Powell County deputy stopped a suspect vehicle near Gold Creek. Both Mack and the female driver were arrested at the time. Julie Anne Hope, 44, of Great Falls was charged with criminal possession of drug paraphernalia and driving with a suspended license; she made a court appearance and is no longer in custody.
Mack was charged with obstructing a peace officer, by providing false information about who he was. Mack appeared in Justice Court and was sentenced on the misdemeanor offense to 180 days in jail, with all but two days suspended; credit for time served, and fined $300 and $85 court fees. Roselles said Mack was being held for Probation and Parole officers to pick him up at the time of the incident.
Roselles said a report has been given to the Powell County attorney with the recommendation to charge Mack with escape and assault of a police officer, both felonies.
