O.J. Simpson Not 'Losing Any Sleep' Over the Knife

BRENTWOOD, CA Locked away in a Nevada prison on robbery and kidnapping charges, O.J. Simpson knows police are testing a knife found at his Brentwood home to see if it was used to kill his ex-wife Nicole Brown Simpson and Ronald Goldman. But he’s not too worried about it.

Simpson’s former manager told People magazine Simpson "isn't losing any sleep. Everybody I've spoken with says he's just ignoring it. He's not talking about it. 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.'"

Last week Los Angeles Police announced that they are investigating a knife found buried outside the former home of O.J. Simpson. The knife was found at Simpson's mansion at 360 N. Rockingham Ave in Brentwood, California, which was demolished in 1998.

A retired LAPD officer claims that a construction worker at the site handed the knife over to him in 2003 and that he tried to turn it over as evidence, but department officials didn’t believe it was necessary, according to the Los Angeles Times.

The department is testing the knife for fingerprints and DNA traces, which could still linger even years later.

“It is being treated as we would all evidence. it has been submitted to our lab," LAPD Capt. Andrew Neiman said.

The Times, citing unnamed LAPD sources reports that preliminary investigation points to the knife being unrelated to the 1994 murders.
