LAPD Finished Testing Knife Found On O.J. Simpson's Estate — See The Results!

According to TZM, LAPD detectives hit a snag with the knife that was buried on O.J. Simpson's Rockingham estate

Sources familiar with the situation confirms that the DNA testing produced no matches. It is understood that the microbes in the soil degraded any DNA to the point it was impossible to get a meaningful result.

TMZ confirms that there was no hair or other sample that produced a lead. It can be recalled that a construction worker found the buck knife with a 5" blade buried on the perimeter of the property and gave it to a retired LAPD cop who was doing traffic control for a movie shoot.

The cop took it home and put it in his tool box for more than a dozen years.The LAPD has not announced the results, but we're told the investigation is over.

Fact is ... it's impossible to know for sure if this was the murder knife, but it is interesting it appears to have been buried long enough to degrade any DNA.
