Margot Kidder died from an intentional drug and alcohol overdose, according to a statement released by the Park County Coroner's Office in Montana and the star's family.
The statement obtained by RadarOnline.com read, "Ms. Kidder died as a result of a self-inflicted drug and alcohol overdose. Her death has been ruled a suicide by the Park County Coroner. Ms. Kidder’s family urges those suffering from mental illnesses, addiction and/or suicidal thoughts to seek appropriate counseling and treatment."
The announcement concluded, "No further details or information will be released in regards to this matter. The public is encouraged to allow the family to grieve privately and to have this matter closed."
The coroner hasn't disclosed what drugs Kidder took.
The actress, 69, who played Lois Lane in Superman opposite Christopher Reeve, was found unresponsive inside her Livingston, Montana home on Mother’s Day, May 13.
Kidder’s body was discovered by a friend who had stopped by to help clean her house.
911 audio revealed that a dispatcher told police and EMTs that a caller described finding a "nonresponsive female, no pulse, no breathing.”
Now it's been determined that Kidder's death was self-inflicted.
Her daughter Maggie McGuane, told the AP that the family wanted to be "open and honest" about the suicide to avoid any "cloud of shame."
Despite her Hollywood success, Kidder battled booze and drug addiction and mental health issues for years.
In 1996, after being reported missing for days, police took her away in handcuffs to Olive View-UCLA Medical Center.
The brunette star was married three times, once to Home Alone actor, John Heard for only six days in 1979. Heard unexpectedly passed away last July due to a heart attack.
Even with her mental health issues, a source told RadarOnline.com after Kidder's death, "Everyone is in shock. Margot kept to herself, but had a lot of friends. And everyone close to her is in the dark about what happened. There are a lot of unanswered questions."
Sadly, now the question of how she died has been answered.
