Law professor: O.J. Simpson is "the case that never ends"

LOS ANGELES -- Police revealed Friday that a knife purportedly found at O.J. Simpson's former property is being tested to see if it is connected to the 1994 murders of Nicole Brown Simpson and Ron Goldman.

The murder weapon used to kill them was never recovered.

The knife was allegedly found nearly two decades ago by a construction worker during the demolition of Simpson's Brentwood estate. The worker reportedly gave it to a police officer.

"The person we received this knife from is a retired LAPD officer who retired back in the late '90s," police spokesman Capt. Andrew Neiman said Friday.

That former officer has not been publicly identified but he's believed to have had the knife for many years before turning it in about a month ago.

Marcia Clark prosecuted Simpson for the stabbing deaths of his ex-wife and Goldman.

"If it does turn out to be connected to the murders of Ron and Nicole, it would be interesting if there was some evidence on that knife that pointed to who might have helped to bury it, if indeed someone else did," Clark told Entertainment Tonight on Friday.

During his trial, Simpson famously tried on a bloody glove discovered at his house. That evidence was dismissed by his attorney Johnnie Cochran after the gloves were shown to be too small.

"If it doesn't fit, you must acquit!" Cochran told the jury.

The LAPD said the story behind this new knife could turn out to be "bogus." It comes to light as a cable mini-series recounting the O.J. saga has renewed interest in the case.

"It's remarkable. I mean, this is the case that never ends," law professor Laurie Levenson told CBS News.

Levenson covered the Simpson trial and said the knife is a fascinating development -- but of little legal significance.

"Even if they find some evidence on this, they would have to show chain of custody, they would have to show how it got there, and even if they said it was O.J.'s and Nicole's, he can not be re-tried for the murder. There's double jeopardy," Levenson said.

Simpson was acquitted of the murders. He is currently serving a prison sentence in Nevada for an unrelated case.

The LAPD won't say how long it will take before they know the results of the DNA tests.
