((AP Photo/Mohave County Sheriff's Office,File)) (Newser) – Federal agents today captured one of the two convicted killers who escaped from an Arizona prison, and were still searching for the other inmate and a suspected accomplice. Tracy Province was arrested with a handgun in northwest Wyoming, about 60 miles outside Yellowstone National Park, said a US Marshal. The other inmate, John McCluskey, as well as suspected accomplice Casslyn Welch, were still on the lam. "They consider themselves as Bonnie and Clyde," said the Marshal. "This is very, very serious business." Efforts to find the trio intensified after they were linked to a double homicide in New Mexico. Province, McCluskey and Daniel Renwick escaped from a private, medium-security Arizona State Prison on July 30 after authorities say Welch threw wire cutters over the perimeter fence. Welch is McCluskey's fiancee and cousin. Renwick was arrested Aug. 1 in Colorado.
