Who is Nathaniel Rai? Dallas boy says 'I thought I was going to die' after dramatic viral ocean rescue

Nathaniel Rai, the Dallas boy rescued from dangerous surf by lifeguard Ryder Williams, recalled the terrifying moment when he believed he would not survive.

Last month, a 16-year-old lifeguard rescued 10-year-old Nathaniel Rai, who was struggling in a rip current off Santa Cruz, California. Rai and his father spoke to "CBS Mornings" about how the terrifying situation unfolded and their gratitude for the teen lifeguard who stepped in to help.
