PHOENIX (AP) — Federal agents on Monday captured in Wyoming one of two inmates who escaped from an Arizona prison, but they still were searching for the other fugitive and a suspected accomplice.

Tracy Province was arrested with a handgun in northwest Wyoming, about 60 miles outside Yellowstone National Park, said David Gonzales, the U.S. marshal for Arizona.

The other inmate, John McCluskey, as well as suspected accomplice Casslyn Welch, were still on the lam.

“They consider themselves as Bonnie and Clyde,” Marshal Gonzales said. “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 the private, medium-security Arizona State Prison near Kingman on July 30 after, authorities say, the 44-year-old Ms. Welch threw wire cutters over the perimeter fence. Ms. Welch is McCluskey’s fiancee and cousin.

The three later kidnapped two semi-truck drivers at gunpoint and used the big rig to get away, authorities said. The group left the drivers unharmed in the truck at a stop just off Interstate 40 in Flagstaff and then fled. Renwick was arrested Aug. 1 in Colorado.

The manhunt intensified Saturday after forensic evidence linked the two inmates and Ms. Welsh to the killings of an Oklahoma couple. New Mexico State Police spokesman Peter Olson declined to elaborate.

The badly burned skeletal remains of Linda and Gary Haas, both 61, of Tecumseh, Okla., were found in a charred camper Wednesday morning on a remote ranch in eastern New Mexico. Their pickup truck later was found 100 miles west in Albuquerque.

Province was serving a life sentence for murder and robbery out of Pima County, Ariz. McCluskey was serving a 15-year prison term for attempted second-degree murder, aggravated assault and discharge of a firearm out of Maricopa County, Ariz. Renwick was serving a 22-year sentence for second-degree murder.

Publicizing their photographs in newspapers and on television, including a segment Saturday night on “America’s Most Wanted,” has helped generate tips, investigators said. A series of billboards featuring the three also is planned.
