A knife found a dozen years ago on land where O.J. Simpson once lived appears to be inconsistent with the 1994 murders of the former football star's wife and her friend, multiple law enforcement sources told NBC News.
Los Angeles police said Friday they were testing the knife, which was recently handed over by a retired LAPD traffic officer, for any possible connection to the murders of Nicole Brown Simpson and Ron Goldman.
Simpson was acquitted in the case, and can't be retried for the killings. The case has remained open.
