A North Texas man is believed to be among more than a dozen people who are missing or are unaccounted for after deadly flash flooding in the Grand Canyon over the weekend. According to the National Park Service, search and rescue efforts are ongoing for at least 15 people believed to have been sw ept away by high water in the Bright Angel Canyon and Phantom Ranch areas. At least one person is confirmed to have died. The body of an unidentified 46-year-old man was recovered from Crystal Rapids along the Colorado River. Among the missing is a 46-year-old chiropractor from Granbury, Dr. John Giusti. Whipple City Family Chiropractic in New York posted a message on Facebook on Sunday from Giusti’s wife saying he was hiking in the Grand Canyon when a flash flood swept through the area where he was camping with two friends. According to his online biography, Giusti was a partner at Whipple City for 12 years before relocating to Granbury and opening Chirohabit. He posted photos of himself from the Grand Canyon on Friday with the caption “Day One. Arrived at the Grand Canyon.” It appears relatives were last able to contact Giusti on Saturday, before the flooding. Giusti is a father of three. His family is asking for prayers at this time. “Dr. John is the heart of ChiroHabit, but above all, he is a deeply loved husband, father, and pillar of our family,” said John’s wife, Janet Giusti, in the shared statement. “​We ask our ChiroHabit community to please lift up my husband, his hiking group, and our families in your thoughts and prayers during this time.” The New York chiropractic office said in the post that they will be taking donations for the Giusti family. The flash flood caused extensive damage to infrastructure in the inner canyon, AP reports. Park services are working to identify the remaining missing Grand Canyon visitors and backpackers. Officials said nearly all footbridges along Bright Angel Creek were destroyed, eliminating hiker access. First responders reported evacuating more than 60 people to safety by helicopter.
