Although O.J. Simpson was found not guilty in the famous and much-disputed 1995 criminal case involving the deaths of his ex-wife Nicole Brown Simpson and her friend Ron Goldman, he lost a wrongful death civil suit brought against him by their families in 1997.

Attorney Daniel Petrocelli had never tried a wrongful death case before representing the Goldmans in their suit. Simpson never took the stand at the criminal trial, so a jury would be hearing from him for the first time under oath.

“That was going to be the moment of truth… to put Simpson under oath and examine him,” Petrocelli told ABC News “20/20” in a recent interview.

Petrocelli deposed Simpson for 13 days prior to the civil trial. The video tapes from this deposition 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.)

In these deposition tapes, Petrocelli is seen grilling Simpson about his alleged role in the murders, covering everything from physical evidence to photographs of Simpson’s shoes.

Here are some of Simpson’s responses to Petrocelli’s line of questioning during the deposition…
