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.

Hogan died at 71 on July 24. According to the Pinellas County Forensic Science Center records obtained by Page Six, his cause of death was ruled to be a heart attack. He had a history of irregular heartbeat and a history of a history of chronic lymphocytic leukemia (CLL), a type of cancer affecting white blood cells.
