Tyson’s Sister Is Dead at 24

The 24-year-old sister of Mike Tyson, former heavyweight boxing champion, died Wednesday of what appeared to be a heart attack.

Denise Anderson, who was found unconscious by her husband in their home in Queens, weighed between 300 and 400 pounds, said police spokesman Officer Ralph St. Just.

Tyson, 23, lost his boxing title Feb. 11, when he was knocked out in the 10th round by Buster Douglas in Tokyo, in one of boxing’s biggest upsets.
