O.J. Simpson's suicide note – famously read by attorney Robert Kardashian on live TV on the afternoon of June 17, 1994, the same day the former football star led police on a dramatic chase through the streets of Los Angeles in his white Bronco – was heavily edited as it was read to the world, according to author Jeffery Toobin.
In a new interview with Dr. Phil, Toobin, author or the book, The Run of His Life: The People vs. O.J. Simpson, which inspired the FX miniseries, "The People vs. O.J. Simpson: American Crime Story," suggests Kardashian corrected Simpson's words to cover up his client's illiteracy.
"It's a shocking document, in and of itself," Toobin tells Dr. Phil of the actual unedited note left behind by Simpson, ahead of his 1994 murder trial, in the deaths of Nicole Brown Simpson and Ronald Goldman.

"What most people didn't know is that [Kardashian] was editing as he went along, that O.J. Simpson was, in fact, barely literate," Toobin tells Dr. Phil in the episode airing Monday, February 1. "They created an O.J. Simpson who didn't really exist in real life."
In another revelation from his book he shared with Dr. Phil, Toobin claims attorney Robert Shapiro advised Simpson to take a manslaughter plea in the murder trial, but the former professional athlete-turned-actor refused and shut Shapiro out, in favor of one of his other attorneys, Johnnie Cochran.
"Johnnie Cochran had a very different strategy," Toobin explains to Dr. Phil. "Johnnie Cochran said we can win this case because the history of the LAPD is so bad when it comes to African-Americans, we can make this jury believe that there was a racist conspiracy to frame O.J. Simpson."
On Monday's episode of Dr. Phil, Toobin shares more insights from his book and insights from behind the scenes of Simpson's infamous trial. Dr. Phil also sits down with family members of Nicole Brown Simpson and Ronald Goldman, who share their feelings on the new FX miniseries, which debuts Tuesday night.
