More tracks, but still no cop-killers in custody.

Despite fresh tracks Wednesday and a sighting of a man thought to be a suspected cop-killer near Montezuma Creek, Utah, Navajo special weapons and tactics teams may again head home empty-handed.

Navajo Nation Police Chief Leonard Butler said searchers found a new set of tracks on the Cahone Mesa at about noon Wednesday, and about 25 officers will continue to follow the tracks until at least today.

Butler said the tracks match those found in Cross Canyon May 29 and around Montezuma Creek over the last several weeks.

The tracks appear to have been left Tuesday night, Butler said.

Butler said the tracks indicate the suspect is staying within a four-square-mile area, just north of Montezuma Creek. All of the sightings, break-ins and unusual nighttime activity has occurred within that area, Butler said.

Butler said he is confident the tracks were left by Alan "Monte" Pilon, 30, of Dove Creek, or Jason McVean, 26, of Durango.

Earlier in the day, a Navajo Nation police captain said the SWAT teams would probably suspend the search until a new sighting or evidence indicates the suspects are still in the area.

"They’re saying if they don’t get anything by tomorrow, they’ll probably wrap it up," Steven Nelson said.

Four Navajo SWAT teams had converged on an area northeast of Montezuma Creek Monday after a Navajo family reported seeing a man dressed in dirty clothing and carrying a backpack limping out of a shallow canyon. The SWAT teams located fresh tracks at the scene and tried to follow the tracks across hot, rocky terrain, Butler said Tuesday.

Cortez police Chief Roy Lane refused to guess if the tracks were left by Pilon or McVean, but said he believes the two fugitives are still in the area between Montezuma Creek and Cross Canyon.

"I think they’re still there," he said Wednesday. "We’re in their ballpark, and we haven’t had a lot of success."

Lane said although the tactical operation to find Pilon and McVean has not been productive, the criminal investigation has been extremely successful.

"The criminal investigation has been a success," he said. "If we can catch them, we can prosecute them."

Pilon, McVean and a third suspect, Robert Mason, 26, of Durango, allegedly killed Cortez police officer Dale Claxton when he stopped them in a stolen water truck May 29. The three men also are suspected of wounding two sheriff’s deputies before fleeing into Cross Canyon, west of Cortez, later that day.
