What happened to Mike Tyson’s sister Denise?

Mike Tyson has lost a lot throughout his life. Jimmy Kirkpatrick, Tyson's father, abandoned the family when he was just two years old. His mother, Lorna Smith Tyson, died in 1982 when he was only 16 years old. ‘Iron Mike’ then suffered another loss eight years later when his only sister died.

According to the Los Angeles Times, Denise Anderson, Tyson’s sister, died on February 21, 1990, of an apparent heart attack at her residence in Queens, New York. She was only 24 years old at the time.

Denise was discovered unconscious by her husband at exactly 8:30 a.m. in their St. Albans home. She was rushed to the intensive care unit but was declared dead on arrival, reportedly due to cardiac arrest.

The LA Times reported that Anderson weighed “between 300 and 400 pounds” at the time. She also reportedly had diabetes and asthma, which were said to have contributed greatly to her untimely passing.

Anderson’s death came a little over a week after Tyson, who was 23 years old back then, lost his undisputed world heavyweight title. He was knocked out in the 10th round by James Douglas in Tokyo, marking one of boxing’s greatest upsets.

More recently, he dropped a video of himself training. During it, 'Iron Mike' looked to be in great shape as he displayed power on the mitts.
