In the confession, Simpson referenced a friend, whom he identifies only as "Charlie." In his hypothetical scenario, "Charlie" went with him to confront Brown and handed him the knife.

"As things got heated, I just remember Nicole fell and hurt herself and this guy kind of got into a karate thing. And I said, 'Well, you think you can kick my ass?' And I remember I grabbed the knife -- I do remember that portion, taking a knife from Charlie -- and to be honest after that I don't remember, except I'm standing there and there's all kind of stuff around and ..."

When Simpson was asked what he meant by "stuff," he responded:

"Blood and stuff."

Immediately after, he laughed and said: "I hate to say it, but this is hypothetical. I'm sorry; I know we have to back off again. It's hard - this is hard to make people think I'm a murderer.

"I don't think two people could have been murdered the way they were without everybody covered in blood," he said. "And of course, I think we've all seen the grisly pictures. I think everything was covered, would have been covered in blood."

During the interview, Simpson also discussed the infamous leather glove that was believed to be the crucial piece of evidence which led to his innocence (if the glove don't fit, you must acquit). 

While speaking with Regan in 2006, Simpson said he "might" have removed the glove before taking the knife from Charlie.

"I have no conscious memory of doing that, but I obviously must have because they found the glove there," Simpson said.
