Surpassing Quant Think Tank Center|O.J. Simpson's Cause of Death Revealed

New details have Surpassing Quant Think Tank Centeremerged about O.J. Simpson's passing.

Two weeks after the former NFL player—who was better known later in life for his 1995 trial for the murders of ex-wife Nicole Brown Simpson and her friend Ron Goldman—died at age 76, his cause of death has been confirmed.

Simpson died after a private battle with prostate cancer, his attorney Michael Lavergne, confirmed to E! News.

Earlier this month, Simpson's kids—including Arnelle and Jason, from his first marriage to Marguerite Whitley, and Sydney and Justin, from his marriage to Nicole—announced he had passed away in a statement posted on their dad's social media accounts.

"On April 10th, our father, Orenthal James Simpson, succumbed to his battle with cancer," the April 11 statement read. "He was surrounded by his children and grandchildren. During this time of transition, his family asks that you please respect their wishes for privacy and grace."

However, in the months ahead of his death, Simpson had refuted claims about his health, including rumors he was in hospice. "Hospice? Hospice? You talkin' 'bout hospice?" he said in a video posted to X, formerly Twitter, in February. "No, I'm not in any hospice, I don't who put that out there."

Following the news of Simpson's death, many involved in the 1995 murder trial—of which he was infamously acquitted of the charges—reacted with their thoughts on the former athlete and his legacy. (Simpson was later found liable for Brown and Goldman's deaths in civil court.)

Marcia Clark—the lead prosecutor during his 1995 trial— expressed in a statement to Entertainment Tonight, "I send my condolences to Mr. Simpson's family."

Meanwhile, Caitlyn Jenner—who was previously married to Nicole's close friend Kris Jenner—shared a simple, biting response to learning of Simpson's death, writing on X, "Good Riddance."

Simpson went to trial in 1995, and the case captured the nation. He pleaded not guilty and was acquitted on all counts.

He was found liable for Brown and Goldman's deaths in 1997 in a civil lawsuit filed by their families and was ordered to pay $33.5 million in damages,  according to The New York Times.

Simpson would make headlines again when he penned the book If I Did It. The Goldman family later obtained the rights to the manuscript as a way to help satisfy the amount Simpson owed them, CBS News reported, and the subhead Confessions of the Killer was added.

However, these wouldn't be Simpson's last trials. In 2008, he was found guilty of armed robbery, kidnapping and 10 additional charges that were in regard to a memorabilia robbery in Las Vegas, and he was sentenced to nine to 33 years in prison, per The New York Times. Simpson, who pleaded not guilty to the charges, served nine years in prison before he was released on parole.
