Yeah, it's a weird story. The kids were swimming and the boy first got caught in the current. Then the sister did too? Then the dad jumps into the water to save the kids? Maybe because the water was pulling them down as well? I'm guessing first grabbed the daughter, then tried to swim to the boy, but the current pulled them far from the boat and they couldn't get back to the boat because the current was too strong. Yet the boy was able to swim to shore so he must of gotten out of the current. I guess the dad was afraid he would of become exhausted from swimming and just tread water, or like someone else said the dad was drunk.
