TMZ: Knife Found on OJ's Property Is a Dead End

TMZ broke the story, and now it's back with the non-story: Though the LAPD has yet to comment, the gossip site says the investigation into the knife found years ago on OJ Simpson's former property is over. TMZ's sources say no usable DNA was recovered from the knife, with any DNA that may have been there apparently "degraded" by soil microbes. With no hair or other forensics present, it's case closed on the knife, which reportedly sat in a retired LAPD officer's toolbox for years. More on how the buck knife came to light here.
