Even while he’s behind bars, O.J. Simpson can’t seem to stay out of trouble! The disgraced Heisman winner is set to meet with the Nevada Board of Parole on Thursday, July 20 — and ahead of his big day, one of his former correctional officers at the Lovelock Correctional Center is sharing details about how a stolen cookie potentially meant huge problems for the 70-year-old.

Jeffrey Felix, who wrote about his relationship with The Juice in his memoir Guarding the Juice, says that it was shortly after O.J. arrived behind bars that the “cookie incident” took place; he tells USA Today Sports that one of the inmates who worked in the kitchen stole cookies and was sharing them with the inmates housed in the unit where O.J. was staying. According to Felix, most of the inmates returned to their cells before eating the sweet treat — but O.J. made the mistake of eating his publicly, catching the attention of one of the guards, who threatened to write O.J. up for a violation that could’ve derailed the possibility of parole.

“Being the loud O.J. he is, the guard in the bubble saw him eating a cookie,” Felix recounts. “And, of course, she said, ‘Where’d you get the cookie from?’ Well, O.J. doesn’t lie. He got it from a guy, a culinary worker. Well she wrote him up for for having contraband. Over a cookie. That’s pretty crazy.”

After the write-up, O.J. confided in Felix and told him that he was fearful that he wouldn’t get parole because of the incident; while Felix tried to ration with his colleague who did the cookie bust, she refused to change her mind — and according to Felix, she became known as the “Cookie Monster,” and had her authority undermined among inmates because of the incident.

O.J. was infamously acquitted for the 1994 deaths of his late wife Nicole Brown Simpson and her friend Ron Goldman in what was dubbed “the trial of the century.” He is currently behind bars serving time for multiple felony charges related to robbery and kidnapping after he was found guilty of robbing a memorabilia collector at gun point. On Dec. 5, 2008, he was sentenced to 33 years in prison with eligibility for parole in nine years — meaning he could be out as early as October of this year.
