The knife found years ago on O.J. Simpson’s property, and currently under investigation by the Los Angeles Police Department, is inconsistent with the 1994 murders of his ex-wife and her friend, NBC News reported Friday afternoon. According to the network’s sources, the knife is a “relatively inexpensive, smaller-bladed utility blade” typically used by gardeners and other laborers. “The characteristics and condition of the knife were not consistent with the weapon used in the [Nicole Simpson] Brown and [Ron] Goldman murders nor does it appear it was buried for a length of time that would put it in the time frame of the slayings,” the report continued. Even if it were the knife used to slay the pair, O.J. Simpson could not be re-tried for the crimes because of his previous acquittal.
