Knife Allegedly Found at OJ Simpson's Estate, LAPD Confirms

LAPD is currently investigating a knife that was recovered on property once owned by O.J. Simpson.

Los Angeles police are currently investigating a knife that was allegedly recovered on property once owned by O.J. Simpson, LAPD confirmed to ET on Friday.

A construction worker found the knife years ago and turned it over to a police officer, according to the Los Angeles Times, and investigators only recently became aware of the existence of the knife when the officer in question retired.

According to TMZ, the officer informed Robbery Homicide detectives of the weapon's existence because he wanted to get it framed. The report further claims an LAPD detective informed superiors, who then launched an investigation and ordered a series of forensic tests to determine if there is any connection between the knife with the 1994 murders of Simpson's ex-wife, Nicole Brown Simpson, and her friend Ron Goldman.

In a press conference Friday morning, LAPD Capt. Andrew Neiman confirmed that the department is investigating the alleged discovery of a knife on the Rockingham property formerly owned by Simpson. He declined to name the retired officer involved in the discovery of the knife, and appealed to the public to help identify the construction worker who allegedly made the original find.

Neiman also said that it is "my understanding that double jeopardy would be in place here" and Simpson could not be retried on murder charges as he was previously acquitted.

Interest in the infamous 1994 Simpson murder trial has surged recently thanks to FX's hit series, The People v. O.J. Simpson: American Crime Story.
