Chris's father, David Mapletoft, said he had no idea his son was taking the pills. He said: "He was already slim, muscular and well built. We just think this was (for him) just another pound or two coming away from the midriff and then he would look fantastic on the beach.
"It is all speculation. We don't 100% know that because we have no idea what he was thinking. I can't think of another reason."
