A new book by former detective Mike Rothmiller claims that Marilyn Monroe was poisoned by Bobby Kennedy, the brother of US President John Kennedy.

Rothmiller says the evidence was hidden in the Los Angeles Police Department archives for six decades.

In an exclusive interview with The Sun Online, Rothmiller alleges that Bobby Kennedy killed Marilyn to silence her from revealing her affairs with President Kennedy and himself.

Rothmiller served in the LA police force’s Organised Crime Intelligence Division for six years and uncovered its darkest secrets.

He discovered secret police dossiers on Marilyn Monroe’s death in the LAPD Intelligence archive in 1978, including copies of Monroe’s diary in which she wrote down her intimate thoughts and the times she had sex with the Kennedy brothers.

Rothmiller’s revelations are told in ‘Bombshell: The Night Bobby Kennedy Killed Marilyn Monroe’.

According to Rothmiller, Bobby Kennedy visited Marilyn’s Los Angeles home to warn her to ‘shut up’ about her affairs with him and President Kennedy.

They had a fight and Bobby Kennedy searched the house to find her diary. Kennedy then allegedly gave her a drugged drink and she was dead by the time he left the house.

LAPD officers from the Intelligence division then covered up the crime, making Marilyn’s murder look like suicide.

LA cops stole her diary and photo-copied its contents detailing her affairs with both Kennedys.

The LAPD had Marilyn under surveillance, installing listening bugs at her house in Brentwood and tapping her telephone.

They also kept secret files on Marilyn’s friend and neighbour, British-born actor Peter Lawford, star of the original Oceans Eleven, who was the Kennedys’ brother-in-law.

Rothmiller found Marilyn’s name linked to files on three Kennedys – the President, the Attorney General, and their brother Edward.

Rothmiller saw the intelligence dossiers on Marilyn and on the Kennedys, especially surveillance reports of when Jack and Bobby were in town.

Their reports showed Robert Kennedy and Peter Lawford were under surveillance by the LAPD the day Marilyn died.

“Like everybody else I thought Bobby Kennedy wasn’t in Los Angeles that day and yet the reports were showing that he was,” Rothmiller said.

He set up a tour for his buddy, his girlfriend, and his wife to the Playboy Mansion in 1982.

There, he met Peter Lawford, who was very haggard and scruffy and looked like he was on drugs or alcohol.

Lawford later contacted Rothmiller and asked to meet him in a park in Los Angeles.

Rothmiller told Lawford about the Playboy Mansion and asked him to tell his story about the night that Marilyn died.

Lawford told Rothmiller that Jack and Bobby Kennedy refused to return her phone calls, and Marilyn threatened to go public about her affairs with them.

If she wasn’t brought under control, the Presidency was in danger.

On August 4, 1962, Bobby secretly travelled from San Francisco to southern California by private aircraft.

Lawford picked him up at the airport and twice drove him to Marilyn’s home.

On their second visit, Marilyn, alone in the house, answered the door and accused Bobby of treating her like a whore.

Kennedy slammed her to the floor, screaming profanities and grabbing her flailing arms by the wrists.

Marilyn struggled free of his grip and slapped him. Kennedy stormed out of the room and began searching through cabinets and drawers in the other rooms, looking for Marilyn’s diary and any other items linking the sexy star to the Kennedys.

Later, Lawford found Bobby in the kitchen, putting something into a glass of water.

Kennedy told Marilyn: “Drink this, you’ll feel better.”

At first, she refused but took a drink and immediately remarked on the unpleasant

In the wake of Rothmiller’s allegations, some experts have expressed skepticism about the validity of the claims.

Historian and biographer David Nasaw, who wrote a book about Joseph P.

Kennedy, patriarch of the Kennedy family, stated in an interview with The Sun that he has “no reason to doubt” that Marilyn Monroe committed suicide.

Nasaw also noted that “there is no one in the Kennedy entourage who has ever said anything remotely like this.”

However, others have pointed out that the Kennedys’ alleged involvement in Marilyn Monroe’s death has been a topic of speculation for decades.

In her 1985 book “Goddess: The Secret Lives of Marilyn Monroe,” author Anthony Summers presented evidence that Marilyn had an affair with both John and Bobby Kennedy and that she may have been murdered to protect the Kennedy family’s reputation.

Additionally, in 2017, the National Archives released a trove of documents related to the JFK assassination, including a file labeled “Robert F. Kennedy,” which contained allegations that he had an affair with Marilyn Monroe and may have been involved in her death.

Regardless of the veracity of the claims, the story of Marilyn Monroe’s alleged murder has captured the public imagination for decades.

Marilyn Monroe was an icon of Hollywood’s golden age, known for her beauty, talent, and tragic life.

Her death at the age of 36 was a shock to the world, and the circumstances surrounding it have remained shrouded in mystery and controversy.

In recent years, interest in Marilyn Monroe has only intensified, with a number of books, films, and documentaries exploring her life, career, and death.

While the truth about her alleged murder may never be known for certain, the story of Marilyn Monroe and the Kennedys remains a fascinating and enduring part of American history and popular culture.
