Jan. 8, 2010 -- Brittany Murphy's mother is heard crying and telling a fire dispatcher that she believes her daughter is dead in an eight-minute 911 call released Friday.
"My daughter's passed out," Sharon Murphy tells the fire dispatcher on the recording. "She's ice cold and her hands are turning blue."
The 32-year-old actress' mother is clearly distraught as she listens to instructions on how to revive her daughter.
"Brittany, please come back!" she cries. "I have two other people with me and we all think she's dead."
Sharon Murphy was not identified on the recording. But sources have identified her and Brittany Murphy's husband, Simon Monjack, as the people who found Brittany Murphy unconscious.
On the recording, Sharon Murphy is asked if she thinks her daughter tried to commit suicide.
"I don't know if it's a suicide," she says. "Very often, her medications get all screwed up. It's probably because of that."
Brittany Murphy was found in the bathroom of her Hollywood Hills home on Dec. 20 and later was pronounced dead at a local hospital.
Brittany Murphy's Christmas Eve Funeral
Brittany Murphy's family gathered on Christmas eve for a small, private funeral service.
Murphy's husband, Simon Monjack, described how he had lost his "best friend and soul mate" as the "Clueless" and "Girl, Interrupted" star was laid to rest at Forest Lawn Memorial Park in Los Angeles' Hollywood Hills, the same cemetery where Michael Jackson was buried in August. "24" actor Eric Balfour attended Murphy's service.
Her family said in a statement that "Brittany was an incredibly loving and passionate person and an artist to her core - she loved acting, singing, dancing, and performing. ... A bright light that lit the world is forever dimmed, but will live on in the hearts of those that Brittany touched."
Family spokesman Alex Ben Block told media outlets Dec. 24, 2009, that a larger memorial service may be held early in 2010.
Also during Christmas week, Monjack rebutted rumors that drugs or an eating disorder contributed to the actress' death, saying that he, along with the rest of the world, wants to know why she died Dec. 19 from a heart attack at age 32.
"These rumors that she was anorexic? It's crazy," Monjack told People magazine Tuesday. "She was slim but that was her natural physique. This is what's killing all of us? How did it happen? Her mum, myself and her family, we want to know why we lost our baby."
Monjack was eager to get the autopsy results, although he initially balked at the thought that "they're going to cut her open," he said, weeping.
On Dec. 21, 2009, the coroner completed an autopsy of the actress. Murphy suffered cardiac arrest at her Hollywood home Sunday and was pronounced dead on arrival at 10:04 a.m. at Cedars-Sinai Medical Center.
It will be four to six weeks before laboratory results are in and the official cause of death can be determined, Los Angeles County Chief Coroner Ed Winter told ABCNews.com.
Monjack, a British writer, producer and director, told People that his wife suffered from a heart murmur, which can cause fatigue, dizziness and irregular heartbeats. But she did not require medication to treat a condition that is generally not life threatening, he said.
The day before she died, he said, his wife was ill and stayed in bed all day. She was suffering from laryngitis, which she treated with herbal tea, ginger and lemon.
"She was on herbal remedies that wouldn't speed up her heart," Monjack said. "There was nothing here that could endanger her. There was prescription medication in the house for her female time and some cough syrup. That was it."
When asked if a drug overdose could have caused her death, Monjack responded: "I can get rid of that one right now."
