Former detective Mark Fuhrman of the O.J. Simpson murder case is still upset over the fact that a bloody fingerprint was discounted during the investigation. Fuhrman is convinced that the print, which he says was overlooked by forensics, would have convicted the former gridiron great of murdering his wife and her pal.

Nicole Brown Simpson and Ron Goldman, who were murdered in cold blood back in June 1994, made headlines all over the world. The pair was mutilated in a blood bath in the Brentwood section of Los Angeles, and O.J. Simpson stood accused. The murder sparked a controversial trial, which resulted in O.J.'s acquittal.

Fuhrman, a hotshot LAPD detective, will forever be remembered for perjuring himself at the trial over his use of the N-word. The detective-turned-best-selling-true-crime author recently revealed that both he and his partner actually found a bloody fingerprint on the brass handle of a gate at the murder scene. Fuhrman claims that the forensics team failed to read his report on the bloody finding in a timely manner, which could have turned the tide of the trial.

The 58-year-old, who now uses his police skills to investigate high-profile murder cases, appeared on 'Oprah' on Monday to discuss how a pertinent piece of evidence like the bloody fingerprint was, for the most part, overlooked:

"When [the murderer] leaves, there is a gate and there is a brass turnstile on that gate," he says. "There is a thumbprint right on the brass turnstile, in blood. As he went through, he pushed it open."

Fuhrman says his partner, Brad Roberts, found this bloody thumbprint and wrote it up very clearly in his notes:

"So all these pieces of evidence I'm noting, and then when I relinquish it, nobody reads my notes for two months," he says. A locksmith eventually threw away the blood-stained gate lock.

Now, 15 years later, Fuhrman told Oprah he had no regrets about his part in the investigation:

"I did good detective work in this case. I brought forward a lot of evidence, and so did my partner, Brad Roberts," he said. "If that would have just been used, history would have been a little different."
