The father of a 10-year-old rescued from pounding surf off the Santa Cruz coast in a dramatic scene captured on video says he is beyond grateful to the teenage lifeguard who saved his son. You have 10 foot waves; you have riptides and currents coming in,” Sumit Rai told The Associated Press on Wednesday. “My son told me that he drowned and my son told me that he went unconscious,” he said. In the video, Williams can be seen diving into a coming wave while holding tight to the boy. Rai said his son told him that he got sand in his lungs and was coughing it out after getting to the shore.
