Renowned author James Patterson has expressed his belief that the iconic Marilyn Monroe was murdered, suggesting that the legendary actress found herself in perilous situations.

Patterson shared these insights during an interview with The Hollywood Reporter as he prepared for the launch of his latest book, The Last Days of Marilyn Monroe: A True Crime Thriller.

“Monroe was involved with high-profile figures like President Kennedy, Robert Kennedy, Frank Sinatra, and even members of the Mafia. She was privy to sensitive information, which she meticulously documented. This knowledge put her in a precarious position,” Patterson revealed to the publication.

The bestselling writer noted, “Many are unaware of the full story surrounding Monroe. There were numerous aspects that even I wasn’t familiar with.”

Patterson pointed out that the general public lacks detailed knowledge about Monroe’s demise, including insights from one of the detectives who investigated her death.

“The 11 foster homes. The fact that she had a pretty bad stutter when she was a kid,” Patterson said. “I didn’t know much about the death scene, about the autopsy not being as complete as it should have been, that one of the detectives was convinced the scene was staged. The key is, a lot of people know about her a bit, but not that much. You’d be surprised.”

Los Angeles police determined Monroe’s Aug. 5, 1962 death was a probable suicide “caused by a self-administered overdose of sedative drugs,” according to History.com.

The book bills itself as a “true crime thriller,” but includes a disclaimer saying it’s “a work of fiction.”

“I mean, she was just a monster of a star, and she kind of threw it away,” Patterson said.
