I am not trying to point fingers, but something doesn't jive. He was a lifeguard and an expert swimmer. I know a little something about this due to the fact that I was planning on taking the test when I was younger and I know what is involved. Five of them went in and only he does not come out. He probably did just get caught in a rip current but I feel a full investigation needs to be conducted to be absolutely positive that this was all it was. The parents deserve the peace of mind to know what really happened out there and in every perspective to feel confident that there was no foul play. If he was my kid, I know I would not be able to rest in any manner till I knew every aspect of the incident and his parents deserve nothing less.
