Brooke Hogan is questioning everything about her dad's death... and now so are fans! The 37-year-old estranged daughter of pro wrestling icon Hulk Hogan was interviewed Tuesday on the Bubba The Love Sponge radio show about her father's death last month at the age of 71. As we've reported, Hulk was felled by an acute myocardial infarction, which is more commonly known as a heart attack. But that wasn't the most surprising thing about his death. The unexpected news was that he was also battling chronic lymphocytic leukemia.
