O.J. Simpson Case at 20: Ron Goldman’s Family, Kato Kaelin Still Plagued by Trial, Killings (Video)

Kim and Fred Goldman and Kato Kaelin on Wednesday's "Today."

Appearing on Wednesday's "Today," Goldman's father Fred said "nothing has changed" since his son was killed 20 years ago, while Kato Kaelin added that it's tough to escape his involvement in the case.

The family members of Ron Goldman, who was found murdered on June 13, 1994, along with Nicole Brown in a crime O.J. Simpson was accused of committing, are still stuck in the '90s in many ways, they said when they appeared with famous houseguest Kato Kaelin on NBC's Today Wednesday morning.

"It's like yesterday," Fred Goldman said of his son's death almost 20 years ago. "The loss is exactly the same. Nothing has changed."

Ron's sister Kim Goldman, who recently wrote a book called Can't Forgive about how Ron's murder affected her life, added that she had to "actively force" herself to move on.

"At the age that I was, you know, early 20s, to be kind of walking away from what I was supposed to be doing, I had to find what was important to me again," she said. "After my brother died, I didn't know what that was because everything shifted and I was lost for a really long time."

Kim also told Matt Lauer that while she's no longer the young girl pictured crying when Simpson was acquitted of murdering her brother and Nicole Brown, she still carries that sadness with her.

"I look at that picture and it makes me so sad because, you know, the sadness on that girl's face. … I don't feel like I'm her as much anymore," she said. "I still carry that angst and that grief with me, but I walk with a little bit more composure now and a little stronger position. But it's heartbreaking to see that, and I was crushed, obviously."

As for Kaelin, he said he's also plagued by the past, feeling like he can't move on from the "character" that was created during the Simpson trial.

"One day I walk into a courtroom. I walk out of a courtroom and everybody's shouting my name. I became this public figure and everybody had an opinion. I was Kato the character. Still to this day I can't believe some of the hate that can come over social media. If I work, they say you're capitalizing — still to this day. If I don't [work], then I'm a bum. I can't really win," he said. "It's a very difficult situation to be in."
