A 10-year-old boy was swept out to sea by massive waves at Seabright State Beach in Santa Cruz, California, and was rescued by 16-year-old rookie lifeguard Ryder Williams. The child had been pulled about 15 yards (13.7m) offshore, but Williams quickly sprang into action, saving the boy's life within just over two minutes. The rescue was captured on video by a bystander, who witnessed several beachgoers also join in to help with the operation. As a result of his heroics, Williams has been invited to the White House by President Donald Trump to receive a high civilian honor.
