Simpson has served nine years of his 33-year sentence and will turn 70 next month.
A California woman who said she saw O.J. Simpson close to the scene of his ex-wife's grisly 1994 murder fears his possible release from prison this fall as the former NFL star's parole hearing nears.
Jill Shively is the only witness who claims she saw O.J. Simpson near the home of his former wife, Nicole Brown Simpson, and her friend, Ronald Goldman, but jurors never heard her story.

Shively says that she's not the only one dreading Simpson's release, as her 28-year-old daughter also has concerns.
“Every year on the day of their murders she's on edge a little bit, because she knows I'm on edge a little bit," Shively told The Hollywood Reporter. "The thought of him being paroled is scary, because you never know what will make him flip out again."
In the interview, she also claims how, after the trial, Simpson was turned away from a restaurant where she was dining and allegedly threw an angry fit at the door.
Shively claims that around the time of the June 1994 murders, she was driving in Brentwood, Calif., just blocks from Brown's condo, when she saw the former football star in his white Ford Bronco speeding through a red light.
In 1994, Shively testified before a grand jury, but she was never called as a witness in the murder trial because she sold her story to the TV show Hard Copy for $5,000, prosecutors said.
“He was like a madman, gone mad insane,” she told Hard Copy in 1994.
For all these years, Shively says she's wondered whether her testimony could have changed the outcome of the trial.
“I should have never sold my story," she told Inside Edition in 2016. "It wasn't worth it. I regret it and I am sorry about that, I am sorry to the Goldman and Brown families."
Prosecutor Marcia Clark said Shively's credibility was ruined and refused to call her as a witness.
“She was mad," Shively said last year. "I mean, she said, ‘You blew my case.’ It was that over and over. And I never forgot it. I felt horrible."
The former Buffalo Bills running back was found not guilty of the murders of Brown and Goldman in 1995. In 1997, he was found liable in a wrongful death suit filed by the families of the victims.
Ten years later, Simpson was arrested after leading a group of men into a Las Vegas hotel and casino to steal his own sports memorabilia at gunpoint.
He was found guilty of 12 counts, including kidnapping, assault, robbery, burglary and conspiracy, and sentenced to 33 years in prison.

That sentence was handed down exactly 13 years after he was acquitted in the Brown Simpson-Goldman murders, a court case regarded as "The Trial of the Century."
Simpson, 69, is currently held in Nevada’s Lovelock Correctional Center after he was found guilty in a Nevada court on 12 counts, including charges of kidnapping, assault, robbery, burglary, and conspiracy, in 2008.
