Los Angeles police are testing a knife found a dozen years ago on the property where O.J. Simpson's wife was murdered — but it is far from clear whether it has any connection to the infamous case, which has remained open since the former football star was acquitted in 1995, multiple law enforcement officials said.
The small, deteriorated knife was recently handed over by a retired LAPD traffic officer, who told police he was working on a film shoot 12 years ago when a construction worker gave it to him, explaining that he had found it on the perimeter of the property, the officials told NBC News.
It's hard to know where the knife came from, let alone what kind of potential evidence, if any, exists on it, officials said. The Simpson house was demolished years ago.
Investigators also trying to confirm the ex-cop's story to determine who'd handled the knife before he obtained it.
The retired officer told investigators that he went to police at the time and was told it was worthless, and could keep it, the officials said. But when he mentioned it to an LAPD detective recently, the detective told him to turn it over.
Simpson's knives were a major theme in his trial because of the manner in which his wife, Nicole Brown Simpson, and her friend, Ronald Goldman, were stabbed to death in June 1994. The trial delved into Simpson's use of high-end cutlery, and his habit of getting them sharpened at a local knife shop.
Officials told NBC News that the retired cop's knife appeared cheap, with no obvious signs of evidence on it.
They described the testing as being done "just in case" it turned up something relevant.
Because he was acquitted, Simpson is immune from being prosecuted again. But no one else has been charged.
Simpson is in prison on an unrelated robbery conviction.
