A brave seven-year-old boy managed to save the lives of his father and sister after a boating accident caused them to float adrift. The children’s father, Steven Poust, had taken his children Chase and Abigail to St. Johns River in Jacksonville, Florida over Memorial Day weekend for a swim. Poust anchored his boat and was fishing while the kids splashed around in the water. There was a strong current in the water that caused the four-year-old Abigail to let go of the boat. Chase decided to let go of the boat as well to try and keep his little sister from drifting away.
