Kidder's daughter said she knew her mother died by suicide the moment authorities took her to Kidder's home.
Coroner Richard Wood confirmed to the Associated Press that Kidder died "as a result of a self-inflicted drug and alcohol overdose".
"It's a big relief that the truth is out there", McGuane said. But she didn't say anything until the coroner released an official statement. A cause of death was not originally reported, but Kidder's manager, Camilla Fluxman Pines, said at the time that she had passed away peacefully in her sleep.
She later appeared in small films and television shows until 2017, including RL Stine's The Haunting Hour. Similar to the Star Wars alum, doctors diagnosed Kidder with bipolar disorder in the 1990s. She wants to avoid any "cloud of shame".
She spoke openly about how she had wandered around Los Angeles for days during that episode, and she said in 2008 that she did not like the words "mental illness". During the interview, she said that she was in bed with the flu, and her voice sounded rough and raspy.
Despite this tragic news, Kidder's daughter, Maggie McGuane, is relieved the truth is now public.
Kidder was working until just prior to her death. Maggie was born on October 28, 1976. While living in Montana, she was also an activist for progressive causes and animal rights. That same year, Kidder was working on her autobiography when her computer was infected by a virus causing her to lose all of her files. "Knowing how many families in this state go through this, I wish that I could reach out to each one of them".
