LOS ANGELES, CA (AP) — 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.

The San Francisco-native and football player 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.
