OJ Simpson Knife

FILE - In this July 29, 1998 file photo, crews demolish the former home of O.J. Simpson in the Brentwood area of Los Angeles. After nearly a month of testing, Los Angeles police detectives have concluded a knife found during the demolition was not the weapon used to kill Simpson's ex-wife Nicole Brown Simpson and her friend Ronald Goldman in 1994. Investigators ruled out the knife after weeks of forensic tests, Police Capt. Andy Neiman said Friday, April 1, 2016. (AP Photo/Mark J. Terrill, File)
