I;d guess heart attack given the relative shallow depth, activity, and age of the diver. BUT THAT IS PURE SPECULATION! But I too would also like to know why if he was indeed diving with a "buddy" they did not ascend and accompany him in. Sounds like he really didn't have a buddy.
Not condemning the buddy but posing a question. With properly trained buddies there should never be separation.
