“Authorities found Butler’s body in a storm drain near the school’s gymnasium. After recovering it, foul play is not suspected in his death, Crean said. Axford told Keys Weekly that Butler was reaching for his keys that fell down the drain when he lost his balance and fell face-first inside. He drowned in 18 inches of water.”
