During his infamous 1995 murder trial, O.J. Simpson invoked his right against self-incrimination and did not testify.
Though he was found not guilty in the slayings of ex-wife Nicole Brown Simpson and her friend Ron Goldman, he lost a wrongful death suit brought against him by their families in 1997.
For the civil case, Simpson went under oath in a pre-trial deposition. Attorney Daniel Petrocelli, representing Goldman’s father, questioned Simpson for 13 days about his alleged role in the slayings.
On Friday, ABC News’ “20/20” will give viewers a look at the videos, which will be featured in the A&E documentary, “O.J. Speaks: The Hidden Tapes,” which premieres Oct. 1 at 9 p.m. ET., and the LMN documentary “The Secret Tapes of the O.J. Case: The Untold Story,” which premieres Sept. 30 at 8 p.m. ET. (Both A&E and LMN are partly owned by ABC News' parent company, Disney.)
