Wednesday (January 20) marks the one-month anniversary of the [article id="1628612"]death of Brittany Murphy[/article] at the age of 32, and with toxicology tests still being conducted, a determination as to her cause of death has not yet been made. The actress' mother and husband continue to maintain that Murphy died of natural causes, not drug use or an eating disorder, as has been widely speculated.

"She had a fear of dying," Brittany's mother, Sharon, told The Associated Press in a Tuesday interview. "She would not take too much caffeine. She wouldn't even have a glass of champagne on New Year's. She was just high on life, and people see that as something else, I guess."

Both Sharon and Brittany's husband, Simon Monjack, maintained during the interview that Brittany did not use drugs or alcohol. Monjack went on to say that some of the prescription medications found in the couple's home belonged to him. He did confirm she had taken klonopin, an anti-seizure medication that can also be prescribed for panic and anxiety disorders, ever since a seizure incident that occurred during the filming of "8 Mile." He said she had also occasionally taken Sarafem, which targets pain and mood swings during menstrual periods. Murphy had suffered flu-like symptoms in the days before her death but took only Robitussin, according to Monjack.

The night before Brittany died, Sharon said, her daughter had talked about having a child, and Monjack said they'd picked out baby names.

Following an [article id="1628688"]inconclusive autopsy[/article], coroner's officials ordered a series of toxicology and tissue tests. Monjack said officials have not contacted him with any information that would indicate his wife died from anything other than natural causes.

While Sharon Murphy said she's tried to ignore reports about her daughter's rumored drug abuse and eating disorder, Monjack called the reports lies and said he is considering suing both British publications and the Los Angeles County Coroner's Department over a list of prescription medications found in Murphy's home that was obtained by TMZ.

As Murphy and Monjack await the coroner's test results, they are planning a public memorial to be held in Los Angeles at the end of February, which will coincide with the start-up of the Brittany Murphy Foundation, a charity aimed at arts education and other causes important to the actress.

"I think the dust will settle, the truth will come out," Monjack said. "I think people will come to realize the genius of Brittany Murphy and come to regret the way they treated her while she was alive."
