No DNA Discovered On Mystery Knife Found Buried Under O.J. Simpson’s House

It turns out the LAPD didn’t discover the knife that killed Nicole Brown Simpson and Ron Goldman 21 years after it would have mattered after all. 

Despite suspicions that a potential murder weapon was found on O.J.’s property a few years after the trial and randomly kept under wraps for another 18 years…DNA evidence to link it to the murders is unsurprisingly nonexistent.

TMZ: LAPD detectives hit a dead end with the knife that was buried on O.J. Simpson’s Rockingham estate … TMZ has learned.

Sources familiar with the situation tell us, the DNA testing produced no matches. We’re told the microbes in the soil degraded any DNA to the point it was impossible to get a meaningful result.

Fears DNA Tests Will Come Up Fruitless in O.J. Simpson Murder Case

The knife buried on O.J. Simpson's former Rockingham estate may hold lots of secrets, but unlocking them may be next to impossible ... with one glimmer of hope.

We spoke with a number of forensic experts who say a knife secreted underground for 4 years is likely to become contaminated by bacteria, chemicals and various microorganisms in the dirt, making it extremely difficult to get meaningful results in DNA tests.  

The experts add the natural elements pose an additional, significant obstacle to DNA tests.

Buck Knife Could Produce Ron and Nicole's Fatal Wounds in O.J. Simpson Murder Case

The knife found buried on O.J. Simpson's former estate was more than capable of inflicting the mortal wounds on Nicole Brown Simpson and Ron Goldman ... so says the man who examined the wounds of the victims.

Dr. Irwin Golden, who served as the Deputy Medical Examiner, testified in the O.J. Simpson case and performed both autopsies, tells TMZ the folding buck knife could have severely cut both victims. Nicole was brutally attacked with a deep neck wound -- 2 1/2 inches deep and 5 1/2 inches across -- and Golden says a 4" blade could have done the deed.  We broke the story ... the knife in question has a 5" blade.

Sources connected with the 1994 investigation and others involved in the evaluation of the knife tell us there was always a wide belief among LAPD cops that Simpson used a buck knife.

Buried Knife Found at O.J. Simpson's Estate

A construction worker found a knife buried on the perimeter of the former O.J. Simpson estate ... and it's currently being tested by the LAPD in a top secret investigation ... law enforcement sources tell TMZ.

The story is incredible. We're told a construction worker found the knife years ago -- we have heard several different stories, ranging from "several years ago" to 1998, when the house was demolished.

The weapon is a folding buck knife.

Our law enforcement sources say the construction worker took the knife to the street, where he saw an LAPD cop. He told the officer where he found the knife and the cop took it.
