TUCSON, Ariz. -- Officials at Saguaro National Park say two men have come forward and are cooperating with an investigation into vandalism along a Tucson hiking trial.
Authorities say at least one saguaro was knocked over and cut in half and a couple of barrel cacti and a palo verde tree were hacked up along the Douglas Spring Trail in Saguaro National Park East.
The cacti and tree were cut up sometime late Thursday or early Friday.
The park service on Monday released surveillance photos following the latest incident showing the two men.
Their names haven't been released.
Earlier this month, park officials say vandals spray-painted several saguaros and boulders along the same trail.
Chief Ranger Paul Austin says the people found to be involved will be held responsible for the vandalism.
