Alberta RCMP are checking reports that a U.S. prison escapee and his suspected accomplice were sighted in the province, but none have been substantiated.
John Charles McCluskey, 45, escaped from the medium-security Arizona State Prison on July 30. He's believed to be travelling with his fiancée and cousin, Casslyn Welch, 44.
U.S. marshals have received reports Welch was seen at a restaurant near Glacier National Park just south of the Alberta border, 400 kilometres south of Calgary. The pair also has ties to Montana.
Alberta RCMP are not conducting an "active border search" but are responding to all possible sightings and tips, Sgt. Patrick Webb said Tuesday. He said Mounties have so far checked out three reports that turned out to be dead ends.
An RCMP helicopter, as well as a U.S. Border Patrol chopper, is working along the U.S.-Canada border but officials in both countries admitted it's impossible to cover the entire boundary.
Investigators believe Welch threw wire cutters over the prison's perimeter fence to help McCluskey and two other inmates escape. Police have since captured the other two men, who had been serving sentences for murder.
Since the escape, the group has been linked to the homicides of a couple whose burned skeletal remains were found in a charred camper in eastern New Mexico.
McCluskey had been serving a 15-year prison term for attempted second-degree murder, aggravated assault and discharge of a firearm in Arizona.
