His little brother fell 100 feet. He went down after him. A 3-year-old boy plunged nearly 100 feet down a cliff and disappeared beneath the freezing water of a creek. Before rescuers could reach him, his 7-year-old brother went down the very same cliff to try to save his life. Dakota Duke was hiking with his family in Oklahoma when his little brother, Riley, slipped over the edge. Dakota did not hesitate. He scrambled down the steep, rocky slope, injuring himself along the way, until he reached the water below. Riley was underwater, badly hurt, and Dakota was not strong enough to pull him out. So the 7-year-old jumped into the freezing creek, grabbed his little brother, and lifted his head above the surface. He held him there, refusing to let him slip beneath the water again as rescuers raced to reach them. Riley suffered a fractured skull, broken ribs, and a serious brain injury. Dakota needed stitches himself. But both boys survived. After everything they had been through, they were eventually back home together. Dakota was only 7 years old. He could not carry his brother to safety, but he did the one thing that mattered most: he kept him breathing until help arrived. Thank God!
