Marson Kay was with a group of divers who went into a cavern with several tight rock formations on Saturday. During their ascent, investigators say Kay became disoriented and got stuck in an opening that was too small to swim through.
The Tampa Bay Times reports the other divers couldn't pull Kay out. So they swam to the surface and sought help. A rescue team went into the water, but Kay was already dead when they reached him.
The medical examiner determined Kay did not drown, but suffered an air embolism.
Hernando County Sheriff's investigators say Kay was a certified diver.
