Last week, the discovery of a knife that was buried on O.J. Simpson's property offered the hope of new insight into the unsolved murder. But the world's most infamous defendent's reaction to the new development is as strange as everything else about the case.
When Simpson heard the news that LAPD was testing the knife as the possible murder weapon, he burst into a loud, uncontrollable laughter, a source from within the prison told Daily Mail Online. “It’s complete bullsh**," Simpson reportedly said. "But this is all they got. It’s pathetic, really pathetic.”

The knife was found at the former star athlete’s Brentwood mansion, and has been unlawfully kept in the custody of a former traffic cop for over 18 years. Only recently was it revealed that the weapon even existed. A murder weapon that caused the death of O.J.’s ex-wife, Nicole Brown-Simpson, and her friend Ron Goldman in 1994 was never found. The knife is currently being tested for any indications that could link the weapon to the two victims' murders. But even if it comes up positive with DNA evidence, O.J. — who is already serving a 33-year prison sentence for unrelated charges — could not be retried for the murders even if evidence was found due to double jeopardy laws.

Still, Simpson is concerned the sudden development could still affect him. “So now somebody else wants to write a book about a f****ing knife,” he told the prison insider. “Now… after all these years a knife mysteriously appears when they know I am up for parole next year. How convenient.”

The knife, which was reportedly found by a construction worker during demolition, was given to the off-duty traffic cop who kept it as a personal memento for nearly two decades before he was asked to turn it over to the LAPD.

Simpson was cleared of killing both victims in the case that became known as “the trial of the century.” He is now serving his 33-year sentence for armed robbery.

Last year, BET aired the news special Who Got the Juice? O.J. Simpson: 20 years later, which featured the memories and opinions of Simpson from the likes of Mobb Deep, Michaela Angela Davis and Al Sharpton.
