Two men cooperating in Tucson cactus vandalism case
Officials with a Southern Arizona National Park say two men have come forward and are cooperating with an investigation into cactus vandalism there.
Late last week, at least one saguaro cactus was knocked over and cut in half at Saguaro National Park in Tucson. In addition, a couple of barrel cacti and a Palo Verde tree were hacked up along a trail in the eastern part of the park.
On Monday, the Park Service released surveillance photos showing the two men following the latest incident. Earlier this month, park officials say vandals spray-painted several saguaros and boulders along the same trail.
The park’s chief ranger says the people found to be involved will be held responsible for the vandalism.
