The terrifying 911 call the Menendez brothers made after murdering their parents has been resurfaced.
On August 20, 1989, Lyle Menendez and Erik Menendez killed their father José, 45, and mother Mary Louise, 47, at their home in Beverly Hills.
The brothers, who are now 56 and 54, were put behind bars three decades ago and are currently serving life sentences.

On the night of the murders, Lyle, then 22, and Erik, then 19, shot their dad five times, and their mom nine times.
The siblings dumped the gun, and their clothes and bought tickets to the cinema to see Batman. They then returned to their home and called Beverly Hills Emergency line, claiming that they found their parents' lifeless bodies.
The haunting audio clip was shared online and revealed a frantic Lyle saying: "Someone killed by parents" to a concerned dispatcher.
Listen to the 911 call below:Lyle's brother, Erik, can be heard bellowing in the background as the receiver continues to ask who murdered their parents. She then asked if Lyle, who at this point was in tears, was still on the line, and he didn't answer.
Several times during the call, Lyle screams "Erik, Erik" to his brother. The handler can also be heard telling their colleague, "We have a hysterical person."
Trying to get to the bottom of the chaos, the second call handler asked who shot the parents, and Lyle responded: "I don't know, I just came home."
The receiver also asked Lyle numerous times if the suspect was still in the house, and he said he "didn't think so." They then assured him that they would be arriving at the residence with an ambulance.

Police didn't suspect the brothers until they started spending their dead parents' money on expensive cars and watches.
Their suspicions were confirmed after Lyle and Erik revealed the harrowing reason why they killed their parents during a recorded therapy session with Dr. Jerome Oziel.
They told Oziel that they killed their mother to put her "out of her misery" while their father deserved to die because "his infidelity had led to that misery," as cited by LA Times.

The siblings were arrested six months after the murders, with Lyle apprehended in March 1990, while Erik handed himself in three days later.
They testified during their court proceedings that they suffered years of physical, emotional, and sexual abuse at the hands of their late mom and dad, saying they murdered them out of self-defense, according to Forbes.
Both men were found guilty on two counts of first-degree murder and conspiracy to murder in March 1996. They are not eligible for parole and will spend the rest of their lives in prison.
The highly-publicized case has been spotlighted in the second season of Ryan Murphy and Ian Brennan's Netflix series, Monsters.
