Former WBC Heavy Weight Champ Ken Norton Sr Dead at 70

Ok this is shocking and a bonafide mystery. But former WBC Heavy Weight Champ Ken Norton Sr died yesterday from an undisclosed cause in a Vetran's Hospital in Las Vegas Nevada. He was just 70 years old. The mystery is the cause of death. I've read a couple of articles on his death and even checked Wikipedia.org but no cause of death is listed. I wonder why? Ken was one of the greats too, he even beat the legendary Muhammed Ali in 1973 in split decision fight. He was awarded the WBC heavy weight title in 1978 when Leon Spinks refused to fight him and fought Muhammed Ali instead. He is survived by his children. Rest in Peace Ken.
