O.J. Simpson, the decorated football superstar and Hollywood actor who was acquitted of charges he killed his former wife and her friend but later found liable in a separate civil trial, has died. He was 76.

Simpson's attorney confirmed to TMZ he died Wednesday night in Las Vegas. A message posted Thursday on Simpson's official X account — formerly Twitter — said he died after battling cancer.

“He was surrounded by his children and grandchildren,” the statement said.

Simpson earned fame, fortune and adulation through football and show business, but his legacy was forever changed by the June 1994 knife slayings of his ex-wife, Nicole Brown Simpson, and her friend Ronald Goldman in Los Angeles.

Live TV coverage of his arrest after a famous slow-speed chase marked a stunning fall from grace for the sports hero.

He had seemed to transcend racial barriers as the star Trojans tailback for college football's powerful University of Southern California in the late 1960s, as a rental car ad pitchman rushing through airports in the late 1970s, and as the husband of a blonde and blue-eyed high school homecoming queen in the 1980s.

“I’m not Black, I’m O.J.,” he liked to tell friends.

The public was mesmerized by his “trial of the century” on live TV. His case sparked debates on race, gender, domestic abuse, celebrity justice and police misconduct.

A criminal court jury found him not guilty of murder in 1995, but a separate civil trial jury found him liable in 1997 for the deaths and ordered him to pay $33.5 million to family members of Brown and Goldman.

A decade later, still shadowed by the California wrongful death judgment, Simpson led five men he barely knew into a confrontation with two sports memorabilia dealers in a cramped Las Vegas hotel room. Two men with Simpson had guns. A jury convicted Simpson of armed robbery and other felonies.

Imprisoned at age 61, he served nine years in a remote northern Nevada prison, including a stint as a gym janitor. He was not contrite when he was released on parole in October 2017. The parole board heard him insist yet again that he was only trying to retrieve sports memorabilia and family heirlooms stolen from him after his criminal trial in Los Angeles.

“I’ve basically spent a conflict-free life, you know,” Simpson, whose parole ended in late 2021, said.

Public fascination with Simpson never faded. Many debated if he had been punished in Las Vegas for his acquittal in Los Angeles. In 2016, he was the subject of both an FX miniseries and five-part ESPN documentary.

“I don’t think most of America believes I did it,” Simpson told The New York Times in 1995, a week after a jury determined he did not kill Brown and Goldman. “I’ve gotten thousands of letters and telegrams from people supporting me.”

Twelve years later, following an outpouring of public outrage, Rupert Murdoch cancelled a planned book by the News Corp-owned HarperCollins in which Simpson offered his hypothetical account of the killings. It was to be titled, “If I Did It.”

Goldman’s family, still doggedly pursuing the multimillion-dollar wrongful death judgment, won control of the manuscript. They retitled the book “If I Did It: Confessions of the Killer.”

“It’s all blood money, and unfortunately I had to join the jackals,” Simpson told The Associated Press at the time. He collected $880,000 in advance money for the book, paid through a third party.

“It helped me get out of debt and secure my homestead,” he said.

Less than two months after losing the rights to the book, Simpson was arrested in Las Vegas.

Simpson played 11 NFL seasons, nine of them with the Buffalo Bills, where he became known as “The Juice” on an offensive line known as “The Electric Company.” He won four NFL rushing titles, rushed for 11,236 yards in his career, scored 76 touchdowns and played in five Pro Bowls. His best season was 1973, when he ran for 2,003 yards — the first running back to break the 2,000-yard rushing mark.

“I was part of the history of the game,” he said years later, recalling that season. “If I did nothing else in my life, I’d made my mark.”

Of course, Simpson went on to other fame.

One of the artifacts of his murder trial, the carefully tailored tan suit he wore when he was acquitted, was later donated and placed on display at the Newseum in Washington, D.C. Simpson had been told the suit would be in the hotel room in Las Vegas, but it turned out it wasn’t there.

Orenthal James Simpson was born July 9, 1947, in San Francisco, where he grew up in government-subsidized housing projects.

After graduating from high school, he enrolled at City College of San Francisco for a year and a half before transferring to the University of Southern California for the spring 1967 semester.

He married his first wife, Marguerite Whitley, on June 24, 1967, moving her to Los Angeles the next day so he could begin preparing for his first season with USC — which, in large part because of Simpson, won that year’s national championship.

Simpson won the Heisman Trophy in 1968. He accepted the statue on the same day that his first child, Arnelle, was born.

He had two sons, Jason and Aaren, with his first wife; one of those boys, Aaren, drowned as a toddler in a swimming pool accident in 1979, the same year he and Whitley divorced.

Simpson and Brown were married in 1985. They had two children, Justin and Sydney, and divorced in 1992. Two years later, Nicole Brown Simpson was found murdered.

“We don’t need to go back and relive the worst day of our lives,” he told the AP 25 years after the double slayings. “The subject of the moment is the subject I will never revisit again. My family and I have moved on to what we call the ‘no negative zone.’ We focus on the positives.”
