LOS ANGELES - OCT 08:  Kris Jenner arrives to the 5th Annual PSLA new documentary titled, The Secret Tapes of the O.J. Case: The Untold Story aired on September 30, 2015 and Kris Jenner (formerly Kardashian) weighed in on the trial and, what she feels, was her own inability to save a friend from domestic violence.

Incredibly, it’s been two decades since the O.J. Simpson trial but it remains a relevant topic of conversation to this day. Jenner, who was a friend of Nicole Brown Simpson continues to be haunted by the red flags she failed to see before Nicole’s murder (along with Ronald Goldman) in Los Angeles on June 12, 1994.

The couples had been close for years (the football legend was even a groomsman at their 1978 wedding) so, when O.J. was accused of killing his ex-wife, Robert Kardashian acted as an adviser to the legal team of his old friend. O.J. was eventually acquitted of the crime.

During the documentary, Jenner explained: “At the end of Nicole’s life, I think she finally was at a place where she knew she had to be more vocal with what was going on and she was in trouble. The one thing she would tell all of us by the time, you know, it got to that level was, ‘He’s going to kill me and he’s going to get away with it.’ I will always feel guilty that I didn’t pay more attention and didn’t speak up when I thought anything was wrong or asked her more, ‘Do you want to talk about it?'”

By the time the trial took place, Jenner and Kardashian had divorced and she was expecting her daughter, Kendall, with Bruce Jenner (now Caitlin Jenner). Still, she sat in the courtroom for the proceedings which included listening to a police call placed by Nicole Brown Simpson just months before her murder. During the call, she is heard saying that her ex-husband, O.J. was “going nuts” and that he was “going to beat the shit out of me.”

Jenner reflected upon hearing this and said: “Her voice, pleading for somebody to come to her house because she thought he was going to beat the s*** out of her, you know, I think that, that was so shocking to me because I had never heard that before.”

The matriarch of the famous clan admitted to speaking to O.J. from jail a few times and that, during the conversations, he said that he “didn’t do it.” Indeed, his legal team was able to convince the jury of this and Jenner remembers looking at her former husband as the verdict came back “Not Guilty.”

Of Kardashian’s reaction, Jenner said: “I think he was shocked. He was definitely stunned. I mean you could look at his face and see it. I’ve known him my entire life. I know that like he was … he was floored that that was the verdict.”

Sadly, Kardashian was diagnosed with cancer and passed away in 2003. Over the years, his relationship with Simpson had deteriorated and even in his final days, the lawyer refused to reconnect with his former friend. As Jenner claims: “O.J. did try to reach out and call him but Robert didn’t take the call.”

Twenty years have passed and, while we may never know the truth, we can still learn a lesson. Domestic violence is serious and can escalate into a life-threatening situation very quickly.
