Lost for decades: Marilyn Monroe’s secret diary surfaces — what’s inside will shock you

Hollywood history is once again surrounded by mystery after claims emerged about a long-lost personal diary belonging to Marilyn Monroe. The legendary actress, who died in 1962, has always been the subject of fascination, speculation, and conspiracy theories. Now, a former LAPD detective, Mike Rothmiller, says he uncovered what many believed had disappeared forever.

For decades, Hollywood has been haunted the alleged disappearance of Marilyn Monroe’s so-called “red diary.”Currently, explosive claims by a former Los Angeles Police Department detective have reignited global discussion, indicating that the diary may not only have existed, but could have revelations tied to power, politics, and Monroe’s final days.


According to a detailed report published by the Daily Mail, retired LAPD detective Mike Rothmiller insists he uncovered the long-lost material buried in confidential intelligence files, a discovery he says could reshape how Monroe’s life and death are understood.

The Hollywood myth of Marilyn Monroe’s missing diary

For many years, Monroe’s speculated diary has been considered as Hollywood folklore, a symbolic lost artifact stated to have vanished following the actress’s sudden passing in 1962.

As Rothmiller explains it, the diary was long assumed to be gone forever. But within intelligence archives connected to an LAPD unit focused on surveillance and political investigations, he stated that he discovered something unexpected.

The Daily Mail report cites that Rothmiller believes the material was kept in classified dossiers rather than publicly archived records, concealed in systems so complex that “nobody would be able to just go in and find them if they didn't know how it worked.”

The alleged discovery inside LAPD intelligence files

Rothmiller, who served in the LAPD’s Organized Crime Intelligence Division in the late 1970s, cites that his access to confidential material resulted in thousands of investigative files on celebrities, politicians, and organized crime figures.

Inside these archives, he claims he discovered a file with the label “Monroe’s Diary.”

He stated that the contents were around 70 photocopied pages of handwritten notes in block letters, comprehending intimate reflections, personal connections, and political observations.

According to Rothmiller, what stunned him most was not only the intimate tone — but also the names and incidents allegedly mentioned.

He told the Daily Mail that finding the diary entries confirmed to him that “As far as we knew, her diary had vanished and was never found.”

Shocking alleged contents: JFK, RFK, and private confessions

The most controversial claims involve Monroe’s reported relationships with President John F. Kennedy and Attorney General Robert F. Kennedy.

Rothmiller asserts the diary has explicit personal reflections, that includes claims regarding emotional intimacy and political connections. One alleged entry cites:

“Bobby and I made love at Peter's. He wants to see me again. This is our secret,”

He also claims Monroe explained contrasting dynamics between the two brothers, including a statement attributed to her:

“Bobby is gentle. He listens to me. He's nicer than John,”

and another more explicit comment reportedly referring to JFK:

“We just kiss and have sex. I wish it was more but it's not.”

If genuine, such claims would significantly intensify long-standing speculation regarding Monroe’s associations within America’s political elite although none of these assertions have been independently verified.

Final diary entries and the night before Monroe’s death

Perhaps the most chilling section of Rothmiller’s account is regarding Monroe’s final alleged diary entries dated just before her passing in August 1962.

He claims one entry references a visit that involves Robert F. Kennedy:

“Peter said Robert will come tomorrow,”

followed by uncertainty in the same note:

“I don't know if he will.”

Within hours of this timeframe, Monroe was discovered deceased in her Los Angeles residence at the age of 36, with her death officially classified as a probable suicide caused by overdose. Rothmiller argues that the timing of the entry raises questions, indicating that it could challenge the long-standing official timeline. However, officials and mainstream historians remain to maintain Monroe’s passing was self-inflicted, and no conclusive proof has ever confirmed otherwise.

Allegations of surveillance, cover-ups, and hidden files

Beyond the diary itself, Rothmiller claims his investigation uncovered extra intelligence material which includes; wiretap transcripts, surveillance notes, and confidential LAPD files. He indicates that Monroe’s communications and those of her associates may have been supervised by law enforcement-linked intelligence operations in that era.

The Daily Mail report emphasizes Rothmiller’s broader assertion that Monroe’s case was entangled in political surveillance networks and that major details may have been modified or withheld. However, these assertions remain disputed and lack official confirmation from the LAPD or government authorities.

Controversy, skepticism, and historical debate

Despite the sensational nature of Rothmiller’s claims, there is no verified proof that Monroe’s diary exists in the form stated, nor that it was authenticated by independent forensic experts. Official records remains to state that Monroe passing from a barbiturate overdose, with her death classified as a probable suicide.

Historians and investigators warn that several theories surrounding Monroe’s final hours, which also includes political involvement, remain speculative and unproven. Still, the enduring mystery remains to spark public fascination, with each fresh claim reopening decades-old questions about fame, power, and truth in Hollywood’s golden era.
