Authorities believe two Arizona prison escapees and their alleged accomplice may be in the Yellowstone National Park area of Montana and Wyoming, based on recent information, the U.S. Marshals Service said Sunday.

John Charles McCluskey, 45, and Tracy Province, 42, are described as armed and dangerous. They have been at large since fleeing an Arizona prison on July 30. A third escaped inmate, Daniel Renwick, 35, was arrested the day after the escape in Rifle, Colorado, where he got in a shootout with police.
