The clip shared by KUTV2 shows at least two people clinging to pieces of fallen trees as they wade through a torrent of muddy water. A woman yells “Daddy!”, possibly to one of the two people seen in the video, as another helpless onlooker gasps, “Oh my God!” The haunting video shot by a helpless onlooker appears to show Jetal Agnihotri being swept away by the flood waters along with another hiker, who was found safe.Twitter / @ArielleHarrison The brother of Jetal Agnihotri – whose body was found on Monday after a massive search – fears the chilling video captures the final moments of his sister, who previously revealed she could not swim. “We think it’s her,” the brother, Pujan Agnihotri, told the local station. His sister was hiking with friends through a well-known slot canyon called The Narrows on Friday afternoon when the group was swept downstream by floodwaters that overflowed the Virgin River. “We think it’s her,” Jetal Agnihotri’s brother told KUTV2.Facebook / Jetal Agnihotri Monsoon rains increased the amount of water flowing there by 8,229 gallons, officials said. Park rangers quickly found an injured hiker who had been swept downstream several hundred meters, as well as several hikers isolated by high water on high ground. Rescuers initially thought they were all accounted for — until hours later, when someone reported late Friday that Agnihotri was still missing, the National Park Service revealed Tuesday. Rangers searched through the night, with additional help mobilized the next day, with water-trained rescuers, search dogs and more than 170 emergency responders, the National Park Service said. The Tucson tourist’s body was finally found Monday, about 6 miles south of where she had been swept away by the Straits, officials said.
