"Witnesses said the family was on the beach, and the boy's sister was in a playpen about 20 to 30 yards from the water, according to Demings. The toddler was nearby, wading in the water.
There are "No Swimming" signs at the lagoon, and no one else was in the water at the time of the attack besides the child, Demings said. "
So they had their 4 year old in a playpen but the 2 year old was allowed to "play" in the water that had "no swimming signs" ?
