A knife found buried at O.J. Simpson's former estate in 1998 is being tested for the presence of DNA.
According to gossip tabloid TMZ.com, a construction worker discovered the folding knife buried on the Brentwood property while demolishing the NFL legend's former mansion in 1998.
The construction worker gave the knife to a traffic officer friend, who kept the knife as a souvenir rather than turn it in as evidence.
Simpson, 68, was acquitted of the 1994 stabbing deaths of his ex-wife Nicole Brown Simpson and her friend Ron Goldman. The prosecutor testified that Simpson stabbed the victims in a frenzied rage because he believed the two friends were lovers.
In reality, Goldman was returning an item that Brown Simpson left at the restaurant where he worked as a waiter.
Even if the knife tests positive for DNA (after 18 years), Simpson can't be tried again due to double jeopardy laws.
In 1997, Simpson was found liable for the wrongful death of Ron Goldman in a civil suit brought by Goldman's parents. He was ordered to pay a $33.5 million judgment to the Goldmans.
In 2008, a court upheld the civil judgment against him.
Simpson was found guilty of 10 counts of armed robbery stemming from a failed heist at a Las Vegas hotel on September 13, 2007.
He is currently incarcerated at the Lovelock Correctional Center in Nevada. He is eligible for parole in October 2017.
