Twenty years have passed since Ron Goldman and Nicole Brown Simpson were murdered. However, a private investigator wants to rehash everything as he claims he can prove that OJ was not their killer.

William C Dear established his very own private investigation agency in 1961 and he has gained a lot of attention for being one of the most decorated eyes on the planet. For every high-profile crime, Dear is lurking in its background.

His most complex case, to date, is the murder case of Nicole Brown Simpson and Ron Goldman. Marcia Clark, famous writer, even wrote an expose about the trial. For the past 20 years, Dear has spent over $1 million of his personal savings in proving that the suspect, Orenthal James "OJ" Simpson was not the murderer.

Over 90 million people at the time watched a very dramatic low-speed car chase that led to the arrest of the former NFL star. The trial went on for a year before a verdict was read, and an estimate of 150 million people tuned in on October 3, 1995 to hear the not-guilty verdict.

Despite consistent protests of innocence, Simpson's acquittal was considered as "one of the worst miscarriages of justice of all time." His acquittal was amidst racism complaints, hints of tampered evidence, and a bungled investigation by the LA Police.

It was in 2008 that Simpson was jailed with the charges of robbery and kidnapping. He was sentenced to 33 years imprisonment, which he is still serving to this day. However, many still believed that in 1994, Simpson literally got away with murder. This is something that Dear strongly disagrees with.

Dear said, "The LAPD had nothing but tunnel vision. They felt OJ did it, they god him and they lost." In reference to the beige carpet in Simpson's house, he said, "There was no blood in the house. You can't fight with a person like Ron Goldman who sustained 27 stab wounds, blood's pouring out all over him, and not attract blood and sand or dirt. How do they account for that nonsense?"

Dear had his own investigation into the case and later made a documentary book about it, "OJ is Innocent and I Can Prove It." His collection of evidence is concrete and comprehensive enough that even those who believed that Simpson was the culprit will re-evaluate.
