Menendez brothers reveal Netflix series made one major error as real prison letter is exposed

The Menendez brothers have revealed a major inaccuracy in the recent Netflix series about their case, and instead have proven what really happened in real life.

The release of the second series of Netflix's Monsters has had the world talking about the true-life case of Lyle and Erik Menendez.

And the noise isn't about to go away after the platform released a documentary today (October 7), titled The Menendez Brothers, where the pair have told their story themselves for the first time.

Viewers have noticed a lot of inaccuracies within the dramatised Netflix show about the brothers' case, which portrays their stories quite differently to how it played out in real life.

In an episode of Monsters, Lyle sends Erik a letter that details an intricate escape plan from jail, which was later found by prison guards.

But the brothers have said the reality of that letter was very different.

The real letter, which Lyle told Erik to destroy, was in fact about what happened to them as children, how he wanted to make his dad proud, and how sorry he really was.

In the documentary, Erik said: "It was a precious letter to me. It was one of those moments when Lyle was really expressing his own pain and I didn’t want to just throw it away because that didn’t happen often between us."

Explaining why Lyle didn't express how he truly felt before writing the letter, he suggested: "He felt that telling the sick secrets of the family would be like killing my parents again and he did not want to do it.”

In the note, Lyle confessed to the brothers killing the parents - a confession which they could never come back from.

Lyle said: "Ultimately it became clear, particularly after they found that jail letter, that there was no way around saying what happened because they had that note.

"They had a confession that we were responsible for our parents’ death.”

Erik added: "As a result of them finding this letter in the summer of 1990, we now had to confess to everyone.”

Commenting on the release of the documentary, Netflix said: "For the first time in 30 years, and in their own words, both brothers revisit the trial that shocked the nation.

"Through extensive audio interviews with Lyle and Erik, lawyers involved in the trial, journalists who covered it, jurors, family, and other informed observers, acclaimed Argentinian director Alejandro Hartmann offers new insight and a fresh perspective on a case that people only think they know."

This comes after the brother's case got a major update as fresh evidence arose in recent weeks, which means the pair could see either a resentencing or a retrial.

The Menendez Brothers is available to stream on Netflix now.
