True crime sleuths and theorists thought the murders of Nicole Brown-Simpson and her friend Ron Goldman could finally be solved after the discovery of a knife on O.J. Simpson’s property came to light last Friday.

However, O.J.’s former manager Norman Pardo says the disgraced NFL star “isn’t losing any sleep” over the latest revelation in the case that has captivated America for over 20 years.

“Everybody I’ve spoken with says he’s just ignoring it. He’s not talking about it,” Pardo told People magazine Monday. “When he heard the news on TV, all he did was shake his head, as if to say, ‘Will this ever end?’ He’s definitely shrugging it off and pretty much saying, ‘I’m not going to worry about it.'”

Simpson is currently serving a 33-year prison sentence in Nevada stemming from an incident at a Las Vegas hotel in 2007. He was charged with armed robbery and kidnapping after confronting men he claimed had stolen memorabilia from his NFL days and will go up before a parole board in November 2017.

“[O.J.] is a little worried because if it’s one his pocket knifes and, if it’s got his blood on it, that could make him look bad when he’s up for parole,” Pardo went on to say.

“That’s really his only fear. Personally, I think it belonged to a construction worker and fell out of his pocket. Honestly, I don’t think it pertains to anything,” he added.

A construction worker is said to have found the knife buried at the Rockingham residence in the Brentwood area of Los Angeles several years ago. He subsequently turned it over to an off-duty police officer, George Maycott, who happened to be nearby, but rather than turning it over the officer kept it, according to the LA Times.

Maycott, since retired, planned to frame the knife and reached out to a friend at the LAPD for the case number of the double murder investigation, which is how it has now become public knowledge.

Simpson was acquitted of the gruesome crime on Oct. 3, 1995, and the knife used in the 1994 attack was never found.
