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.

The late wrestling legend’s daughter, Brooke Hogan, has publicly expressed doubt about Hulk’s death and requested an autopsy be performed.

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
