DAYTONA BEACH (CBSMiami/AP) – The father of a six-year-old boy who drowned at a Daytona Beach water park said he only looked away for a moment.

Lamar Farrell says Kaiden Lawson was playing in the wave pool at Daytona Lagoon with his 9-year-old brother on Saturday when the waves started. Farrell says he looked away briefly to tend to a younger son and when he looked back, he only saw the older boy.
