Dr. Phil and and his wife Robin mourn the loss of one of their closest family members

Dr. Phil McGraw and his wife Robin McGraw are mourning the loss of Robin’s sister, Cindi Broaddus. She was 68 years old.

Broaddus survived a dangerous acid attack 17 years ago, and according to an obituary in The Duncan Banner, she died on Feb. 19. Her funeral was held on Feb. 23, her birthday.

“In 2001, Cindi survived a random act of violence when someone threw a jar of sulfuric acid off an overpass. This one act started her journey of courage and the inspiration for her book ‘A Random Act’. Spreading her message of courage, she inspired a multitude of people. She was brave until the very end,” the obituary stated.
