LOS ANGELES — More than 20 years after O.J. Simpson's ex-wife and a friend were stabbed to death, police revealed Friday they are examining a knife that was reportedly found at the home where the former football star was living at the time.
The announcement marked yet another twist in a case that's had more unexpected turns than television's best crime shows. The knife was believed to have been recovered by a construction worker tearing down the house. The worker then gave it to an off-duty police officer who was working as a security guard at a filming location, police said.
It was unclear when the knife was found and how long it was held by the officer, who is now retired. The knife was being analyzed by a Los Angeles Police Department crime lab for DNA or other material that could possibly link it to the killings.
Capt. Andy Neiman stressed that the authenticity of the story was not confirmed and that investigators were looking into whether "this whole story is possibly bogus from the get-go."
"It's unusual how this all of a sudden becomes a huge story during this time," Neiman added, referring to the popular "People v. O.J. Simpson: American Crime Story" anthology that is airing on the FX television channel.
Simpson was charged and acquitted in the slayings. Even if the knife is linked to him, legal experts say he could not be criminally charged again because of protections against double jeopardy.
"If they were going to find this knife and make it useful in the murder trial, they should have found it 20 years ago, and they didn't," said Loyola Law School professor Laurie Levenson, a former federal prosecutor and longtime observer of the Simpson case. "It will just raise more questions about the incompetence of the investigation and probably lead to more books and more movies."
The weapon used in the killings has been a mystery for decades. Other knives have surfaced during the case but were not linked to the crimes.
