It was the second tragedy to hit the Foreman family in a month.
On March 11, Foreman's daughter, Freeda Foreman, also a former professional boxer, was found dead in her Texas home.
George Foreman, 70, a member of the World Boxing Hall of Fame and the International Boxing Hall of Fame, won a gold medal in the heavyweight division at the 1968 Olympic Games in Mexico City. On Jan. 22, 1973, he knocked down Joe Frazier six times to score a technical knockout and win the heavyweight title in Kingston, Jamaica. He lost the title to Muhammad Ali in 1974, but 20 years later stunned Michael Moorer to regain the crown.
