"Two escaped Arizona convicts and a Mesa woman suspected in the slaying of an Oklahoma couple were believed to be in Yellowstone National Park on Sunday and becoming increasingly desperate," the Arizona Republic writes.

As the Associated Press adds:

"The U.S. Marshals Service said Sunday information developed within the past two days indicates Tracy Province, John McCluskey and Casslyn Welch may be hiding in portions of the park that span Montana and Wyoming. The agency also said investigators believe Province has separated from McCluskey and Welch."

KPNX-TV in Phoenix filed this video report:

The fugitives are, not surprisingly, considered to be "armed and extremely dangerous," according to the U.S. Marshals. They escaped custody on July 30, allegedly with help from Welch.

Province had been serving a life sentence for murder and robbery. McCluskey was serving a 15-year term for attempted second-degree murder, aggravated assault and discharge of a firearm.

A third man who escaped with them, Daniel Renwick, was captured Aug. 1.
