Buried Knife from O.J. Simpson Estate NOT Tied to the Murders

The knife found on the grounds of O.J. Simpson's Rockingham estate has no connection to the murders of Nicole Brown Simpson and Ron Goldman.

The LAPD confirmed their testing of the folding buck knife revealed no evidence linking it to the double murder. As TMZ first reported ... microbes in the soil had degraded any possible DNA, so it was impossible to get any meaningful results.
