LOS ANGELES (AP) -- A law enforcement official says the knife reportedly found at O.J. Simpson's former estate likely isn't connected to the killings of his ex-wife and her friend, but it will take at least three weeks to know for sure.
The official with knowledge of the investigation told The Associated Press that Los Angeles police detectives doubt the knife was used in the 1994 killings.
The official says the knife is common among gardeners and is too small to make the wounds that killed Nicole Brown Simpson and Ronald Goldman.
The official is not authorized to publicly discuss the investigation and spoke only on condition of anonymity.
Police Capt. Andy Neiman said Wednesday that investigators examining the knife don't expect results for at least three weeks.
The department's crime lab is looking for DNA or other material.
