Police: Knife found on former O.J. Simpson estate

(CNN) — A knife has been recovered at the Los Angeles-area estate once owned by former football star O.J. Simpson, who was acquitted more than 20 years ago in the killings of his ex-wife and her friend.

It’s not known when the knife was discovered or whether it is related to 1994 deaths of Nicole Brown Simpson and her friend Ronald Goldman, according to Los Angeles police spokeswoman Norma Eisenman.

The knife was found on Simpson’s former estate in the Brentwood area of Los Angeles.

Flanked by his all-star legal team, Simpson was found not guilty in the two killings on October 3, 1995.

Testimony in the trial took about nine months, encompassing about 120 witnesses, 45,000 pages of evidence and 1,100 exhibits.
