Ashley Judd Confirms Naomi Judd Died by Suicide: 'The Lie the Disease Told Her Was So Convincing'

Editor's Note: This story includes graphic details of a death by suicide.

Ashley Judd is sharing more about her mother Naomi Judd's cause of death.

The actress told Diane Sawyer in an emotional interview that aired Thursday on Good Morning America that Naomi "used a weapon" when she died by suicide on April 30.

"Because we don't want it to be part of the gossip economy I will share with you that she used a weapon; my mother used a firearm," said Ashley, 54. "So that's the piece of information we are very uncomfortable sharing, but understand that we're in a position that if we don't say it, someone else is going to."

Ashley added that Naomi, who was 76 years old when she died, "was seen and she was heard in her anguish, and she was walked home."

"When we're talking about mental illness, it's very important to be clear and to make the distinction between our loved one and the disease," she continued. "It's very real … it lies, it's savage."

"I'm gonna make this fast because my heart's broken — and I feel so blessed," Wynonna told the 800 people gathered in Nashville's CMA Theater for the Country Music Hall of Fame induction ceremony. "I mean, it's a very strange dynamic to be this broken and this blessed."

"Our mother couldn't hang on until she was inducted into the Hall of Fame by her peers," Ashley told Sawyer, 76, on Thursday's GMA. "That is the level of catastrophe of what was going on inside of her, because the barrier between the regard in which they held her couldn't penetrate into her heart, and the lie that the disease told her was so convincing."
