“There will be plenty of additional investigation.”

The Los Angeles Police Department is investigating after a knife was found buried on O.J. Simpson's former estate in Brentwood, police tell The Hollywood Reporter.

Detectives are now on the case, say police.

The knife, allegedly folding in style, was in the possession of a now-retired LAPD officer who "believed the case was closed," says an LAPD spokesman. “There will be plenty of additional investigation.”

The unidentified officer was given the knife while working as security for a movie being shot near Simpson's Brentwood home, which was being torn down, say police, adding that charges against the officer will be looked into.

The knife currently is undergoing forensics testing, say police.

Simpson was acquitted of the 1994 murders of Nicole Brown and Ronald Goldman, both of whom were stabbed to death.

However, no matter the possible new evidence, Simpson cannot be tried for the case again, since he was acquitted originally; that legal provision is known as "double jeopardy."

Interest in the case recently has been reignited, due to the FX series The People v. O.J. Simpson: American Crime Story.
