U.S. Marshalls are looking for a fugitive and his fiancée in a remote part of Montana just east of Glacier National Park. John McCluskey, 45, and Casslyn Welch, 44, have been tracked across the west, from New Mexico to Wyoming and Yellowstone National Park. McCluskey escaped from a privately-run prison in Arizona with two other men, Tracy Province and Daniel Renwick, on July 30. Officials think the men escaped after Welch, who is also McClusky’s cousin, threw wire cutters over the prison’s perimeter fence. Renwick was picked up in Colorado, and Province was nabbed in Wyoming Monday. Authorities are offering a $40,000 reward for the couple’s capture.
