In the aftermath of the O.J. Simpson murder acquittal that divided a nation, many focused on the 12 jurors responsible for allowing the accused to go free. Several of those jurors made media appearances, gave interviews defending their decision and even wrote books about the trial -- but one person who wasn't having any of it was Atlanta prosecutor Nancy Grace.

Grace appeared alongside three jurors-turned-authors during an episode of "Geraldo" that aired in 1995. While what happened on the air was contentious enough, Grace now tells a special edition of "Oprah: Where Are They Now?" that a particular moment after the taping is what truly disturbed her.

Grace says that she and the three jurors -- former forewoman Amanda Cooley, Carrie Bess and Marsha Rubin-Jackson -- were standing outside the studio when a stretch limo pulled up.

"They all were getting into the limo," Grace recalls. "One of them had her arm on the door. Just before she got in, she turned and she said, 'You know, Nancy, the O.J. Simpson case -- this trial -- it's the best thing that ever happened to me. I get to come to New York, I get all these nice clothes, I get all these interviews, I get to stay in all these hotels and [eat] fancy dinners. I mean, it's been great!'"

Grace was appalled. Even retelling the story today, more than 20 years later, she appears emotional.

"I remember thinking about Nicole Brown and Ron Goldman lying there in blood," Grace says shakily. "I started crying... I'll never forget it as long as I live."

The "Oprah: Where Are They Now" special "The People Versus O.J. Simpson" airs Saturday, April 2, at 10 p.m. ET on OWN.
