U.S. Marshals are continuing their search today for two Arizona prison escapees thought to be hiding out in the Yellowstone National Park area; the pair are suspects in a New Mexico murder and are considered to be armed and dangerous.

Marshals from Arizona are working with offices from the National Park Service on a search for the escapees and their accomplice; it's believed they've now split apart, according to officials, who are working off what they consider to be a credible tip that the trio headed to Yellowstone yesterday.

John Charles McCluskey (left), 45, and Tracy Province (right), 42, escaped a private prison in Kingman, Arizona prison on July 30 and headed out of the state. Their accomplice, 43-year-old Casslyn Mae Welch (center), threw tools onto the prison yard, allowing them to escape. The pair are described by the U.S. Marshals Service as being armed and dangerous: Province was serving a life sentence for murder and armed robbery, while McCluskey was serving 15 years for attempted second-degree murder, aggravated assault and discharge of a firearm.

"Information developed within the past two days indicated the escapees may be hiding in the Yellowstone Park area within Montana and Wyoming," U.S. Marshals said in a statement Sunday. "It is believed Tracy Province has separated from John McCluskey and Casslyn Welch."

The pair have gone on a spree of sorts since breaking out of prison: they are suspected in the murder of an Oklahoma pair traveling in New Mexico as well as allegedly hijacking an 18-wheel truck.

Whether Yellowstone is the ultimate destination for the trio remains to be seen; Canadian Mounties warned last night that the trio may have a goal of heading into Canada.
