"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 in documentary The Secret Tapes of the O.J. Case: The Untold Story, premiering September 30 at 8 p.m. on A&E.

OJ Simpson and Kris Jenner.

“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?”’

Kris' first husband Rob Kardashian, Sr. served as OJ's defense lawyer. The former NFL star was acquitted of murder charges, but was found guilty in a civil lawsuit. He is currently serving a 33-year sentence pertaining to theft charges.
