Count Frank Sinatra among those who believe Marilyn Monroe was murdered. As soon as her death was announced, theories about how she died bubble up. 

The Chairman of the Board’s manager Tony Oppedisano wrote a book about the time he spent with Frank Sinatra which will be released shortly.

Oppedisano says of his memoir, “I tried to paint the portrait of a man very few people got to know as well as I did. I think he knew someday I’d share the stories he wanted the world to know.

While there certainly are many behind-the-scenes revelations in the upcoming book, the comments about Marilyn Monroe are striking a chord because of the pair’s close friendship.

“Frank believed she was murdered,” Oppedisano wrote in his memoir “Sinatra and Me: In the Wee Small Hours.”

Marilyn Monroe Was Reuniting With Joe DiMaggio

Marilyn had a lot to celebrate but instead she was found dead on August 4, 1962. She was 36 years old.

She was preparing for an upcoming press conference to announce she was getting back with her ex-husband Joe DiMaggio.

In fact, the weekend before her death in 1962, she was with the baseball legend at Cal Neva Lodge, which Frank Sinatra partially owned.

“Frank believed if the press conference hadn’t been announced, she would have lived a lot longer,” Sinatra’s manager wrote.

Oppedisano believes the buzz about the press conference was interpreted as Monroe’s intentions to expose John and Robert Kennedy and their affairs.

It was believed she had affairs with the political giants.

There are been many theories about Monroe’s death over the years. Some thought the Kennedys were involved or the mafia and even a cover up by her doctor. But, nothing has ever been proven.

Affair With John And Robert Kennedy

Marilyn reportedly told Sinatra about her affairs with the Kennedy brothers and he believed it. 

The book claims that Marilyn “told Frank she didn’t understand why they’d shut her out completely once she stopped having sex with them.”

Monroe’s official cause of death was from an overdose and empty pill bottles were found around her room.

Police concluded the starlet’s demise was “caused by a self-administered overdose of sedative drugs and that the mode of death is probably suicide.”

Sinatra heard that several of mob boss Sam Giancana’s men were involved in Marilyn Monroe’s death and he tended to believe it.

Giancana was rumored to have had a hand in John Kennedy’s 1960 White House victory. 

According to his manager, Old Blue Eyes was “haunted” by Marilyn’s death.

They were never lovers, but rather good friends. Sinatra didn’t have a sexual relationship with her, he believed Marilyn was too vulnerable. 

“Frank felt she was too troubled, too fragile, for him to sleep with and then walk away,” Oppedisano stated.
