The 1995 O.J. Simpson criminal trial remains one of the most controversial cases in the United States. The retired football star and actor was found not guilty of killing Nicole, 35, his ex-wife, and her friend Ronald L. Goldman, in her Los Angeles home.
Kris, 59, was friends with both of them and was pregnant with daughter Kendall Jenner, now 19, during the trial. Her ex-husband, Robert Kardashian, father of Kim Kardashian, Kourtney Kardashians, Khloé Kardashian and Rob Kardashian, was a member of O.J.'s "dream team" defense.
In her 2011 memoir, Kris Jenner...and All Things Kardashian, Kris says she spoke to Nicole hours before she was stabbed to death.
"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?'" ABC News quotes Kris as saying in the LMN documentary The Secret Tapes of the O.J. Case: The Untold Story, which premieres on Sept. 30.
"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," Kris says. "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.'"
Kris says on the program that she and Robert never spoke about the trial. She also says O.J. talked to her over the phone from jail while the proceedings were going on and that he told her, "I didn't do it."
While he was acquitted in a criminal trial, the former football star was found liable for the deaths by a civil jury in 1997. He was ordered to pay $33.5 million to the victims' families.
In 2007, he released the ghostwritten book If I Did it: Confessions of the Killer, a hypothetical account of Nicole's killing. A federal bankruptcy judge awarded 90 percent of the proceeds from the sale of the rights to the publication to Goldman's family.
In 2008, O.J., 68, was convicted of robbery, kidnapping and burglary after storming a Las Vegas hotel room with other men and taking memorabilia from two sports collectibles dealers. He was sentenced to up to 33 years in prison with the possibility of parole and is currently serving time in a Nevada correctional facility.
