Los Angeles police detectives have concluded a knife found at the former estate of O.J. Simpson was not the murder weapon used to kill Simpson's ex-wife Nicole Brown Simpson and her friend Ronald Goldman.

Police Capt. Andy Neiman said Friday that investigators ruled out the knife after weeks of forensic investigation.

Simpson was acquitted of stabbing to death his wife and Goldman outside her condominium on June 12, 1994.

A knife linked to the killings has never been found.

Police revealed last month they were testing one a construction worker said he found on Simpson's property 12 or 13 years ago and passed on to a retired police officer.

Police say they only recently learned that the officer, now retired, still had the knife.
