A Phoenix man was killed when he fell off a cliff overlooking the Colorado River at the Glen Canyon Dam Overlook near Page Sunday. Witnesses told authorities a man, later identified as 25-year-old Orlando Serrano-Arzola of Phoenix, was rock climbing on top of the rim overlooking the Colorado River, taking pictures, when he fell approximately 100 feet and then slid approximately 150 feet further. The victim suffered severe trauma and showed no signs of life after the fall. A Coconino County Sheriff’s Office Deputy rappelled to the victim at 9:27 a.m and confirmed the Serrano was deceased. The Coconino County Sheriff’s Office, National Park Service, Page Police Department and U.S. Bureau of Reclamation provided assistance with recovery operations. The victim was transported to the Medical Examiner’s Office in Flagstaff for an autopsy. At the same time of the recovery, human bones were found at the same location. The remains have also been taken to the Medical Examiner’s office for testing.
