Police in Florida are still investigating the death last month of professional wrestling icon Hulk Hogan from what the medical examiner concluded was a heart attack.

No foul play suspected after the wrestler's death from a heart attack, but Clearwater police said the "unique nature" of the case has required a longer investigation

It sounds like the cause of Hulk Hogan’s death is related to a surgeon severing the phrenic nerve that helps control breathing.
