Only in the new issue of Closer Weekly, Marilyn Monroe’s friends and family insist that Marilyn did not take her own life, while a new book, Marilyn Monroe: Day by Day, reveals new details from the star’s diary and the days leading up to her death.

Marilyn had made plans for “the day after she died…She was going to see the producers,” Marilyn’s niece Mona Rae Miracle tells Closer. “It was very clear the studio was going to rehire her,” notes Carl Rollyson, author of Marilyn Monroe: Day by Day, a new book that reveals the most comprehensive account of her last days through a paper trail of hidden diaries and appointment books. “She was making plans for the future.”

Still, 50 years after her death, many believe it wasn’t suicide at all, but a tragic accident caused by the actress taking too many sleeping pills. “If Marilyn had a sleeping pill at her side, she would always take it,” Jimie Morrissey, Marilyn’s hairdresser, reveals to Closer. “She was always taking pills. And she was always drinking champagne.”

But the self-medicating couldn’t completely take away her pain. “She was in a bad place mentally for a while,” Sherrill Snyder, the daughter of Marilyn’s longtime photographer and close friend Allan “Whitey” Snyder, tells Closer. “People were giving her pills because they needed her to perform,” she says. “Unfortunately, Marilyn was surrounded by people who were less than vigilant” about tracking her medication. “One thing led to another, but my father never believed it was suicide.”
