TUCSON, Ariz. -- Two men have come forward and are cooperating with an investigation into vandalism in Saguaro National Park.
Several cactuses, including at least one saguaro, were damaged along the Douglas Spring Trail last week. It was the second time in a month that vandals struck the area.
On Monday, the National Park Service released surveillance photos showing the two men they identified as persons of interest.
Chief Ranger Paul Austin said the men are cooperating fully with National Park Service law enforcement.
Their names have not been released.
In mid-May, graffiti was discovered on eight saguaro cactuses, signs and rocks along the same hiking trail. Park officials said many of the cactuses tagged were 100 to 150 years old.
Austin said any individuals found to be involved in the vandalism will be held responsible.
