After two days of searching for two suspected cop-killers in southeastern Utah, the Navajo Nation withdrew its two remaining Special Weapons and Tactics members from the area, saying it found little more than some faint footprints in the sand.

Two SWAT teams conducted a final search of the area between Montezuma Creek and Hatch, Utah, Tuesday evening before returning to Shiprock, said Randy John, the captain of the Navajo Police Department’s Criminal Investigations Division in Shiprock.

John said the Navajo police will continue to investigate sightings of men resembling Alan "Monte" Pilon, 31, of Dove Creek, and Jason Wayne McVean, 27, of Durango, but there are no plans to send SWAT teams back to the area until they receive some "solid" reports.

About 40 SWAT team members had returned to Montezuma Creek on Sunday evening after residents reported seeing two suspicious fires and some unusual vehicle traffic in recent weeks.

The teams found two sets of boot prints, one flat-soled and one lug-soled, but Navajo Nation Police Chief Leonard Butler said they were unable to determine if either of the tracks were left by Pilon and McVean.

Pilon, McVean and a third man, Robert Mason, 26, of Durango, are suspected of shooting Cortez Police officer Dale Claxton seconds after Claxton stopped the three men in a stolen water truck May 29 in Cortez.

Mason was found dead of a self-inflicted gunshot wound June 4 about 10 miles west of Montezuma Creek.
