Screen grab from TMZ.
TMZ, which originally broke the odd story about a knife being found years ago buried on the former O.J. Simpson property in Brentwood, now says lab tests have found no evidence of any DNA or hair. Zilch. So, now it's back to just being a knife that a retired cop says he was given years ago by a construction worker, with no connection to any murders other than the location where it was reportedly found. TMZ notes that the LAPD says its lead investigator has not yet gotten this information back from the crime lab. Which may be true too.
