Nicole Brown Simpson endured years of verbal and physical abuse during her relationship with ex-husband O.J. Simpson.

But when she was brutally murdered in June 1994 alongside her friend Ron Goldman outside her Los Angeles home and O.J. was considered the prime suspect, many of her loved ones believed he was the culprit. And even Nicole herself once said he would kill her one day.

After filing for divorce from O.J. in 1992, Nicole experienced a brief moment of excitement and independence, including dating and living on her own with their two children, Sydney and Justin. According to her family and friends, O.J. was jealous of her relationships with other men and stalked her, sometimes hiding in bushes outside her Brentwood, Los Angeles, house, as revealed in the second episode of The Life & Murder of Nicole Brown Simpson.

Nicole called 911 one evening after O.J. confronted her after seeing her and the man she was dating at the time kissing on the couch through a large window of her home, Nicole’s friend, Robin Greer, claims in the episode.

“She told me there had been ongoing problems and then she said ‘I know for a fact he’s going to murder me one day,'” recalls retired Los Angeles police officer Spencer Marks, who responded to the scene.

Marks continues, “That sort of took me by surprise. If you know he’s going to murder you one day then how do we prevent that? We need to keep you away from him. She sort of 'poo-pooed' it and said ‘Well, you know, we’re trying to work on things. So, you know, it’s what we have to do.’”

This incident was not the first time Nicole called the police on O.J. believing the abuse would end in her demise. An entry from Nicole’s private diary — in which she detailed a list of abuse by O.J. and is shown in the episode —  states that he had chased her around his Rockingham estate and beat her on a bed until the police came on one New Year’s Eve prior to their divorce.

During the subsequent murder trial dubbed the “Trial of the Century,” LAPD detective John Edwards, who was a witness for the prosecution’s case against O.J., recalled responding to the home that day with a partner.

“She collapsed and started yelling, ‘He’s going to kill me, he’s going to kill me,’” Edwards testified. He told the court she had a one-inch cut on her upper lip, a swollen right forehead, a black eye and a hand imprint on her throat.

Despite the prosecution’s case alleging a long history of abuse, O.J. was found not guilty of murdering Nicole and Goldman. He was, however, ordered to pay $33 million in 1997 after the victims’ families filed a civil lawsuit. O.J. maintained his innocence for decades and lived the rest of his life in infamy until his death from cancer on April 10.

His death left Nicole's three sisters, Tanya, 54, Dominique, 59, and Denise, 66, with mixed emotions, they previously told PEOPLE.

"It’s very complicated,” Dominique said in May. Tanya added, "This is a person who’s been in our life for a very long time, who wreaked havoc on our family. It’s like the end of a chapter."
