(NEWSER) – Its sources are just that—"sources," with no more specific identifiers other than that they're in law enforcement—but TMZ has an incredible story about an allegedly hush-hush investigation being conducted by the LAPD in connection with a knife supposedly found on the perimeter of the former OJ Simpson estate.

Per these insiders, a construction worker found what's said to be a folding buck knife years ago, possibly when the estate was razed in 1998. He immediately handed it off to an off-duty cop who, as the story goes, is said to have secretly taken it home. The officer not only allegedly kept it for years, but tried to frame it, which is when the TMZ story says the knife's existence came to light.
