Police have previously said there was no evidence of foul play in Hogan’s death, so it’s not clear exactly what the police probe is looking into other than medical records. Hogan previously had leukemia and atrial fibrillation, an irregular heart rhythm, according to the medical examiner’s report that concluded the cause of death was natural.

WWE legend Hulk Hogan may have died as a result of medical malpractice, according to a new report. The wrestling icon, whose real name was Terry Bollea, died from cardiac arrest on July 24 at the age of 71.

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
