( CNN ) -- The jury that convicted O.J . Simpson of robbery and other charges relied mostly on audio and video evidence -- and very little on testimony from prosecution witnesses -- jury members said Sunday . O.J . Simpson , convicted of robbery and kidnapping last week , could be sentenced to life in prison on December 5 . `` We honestly felt we could not rely on that witness testimony , '' said Michelle R. Lyons , one of seven jurors who spoke to reporters in Las Vegas , Nevada , on Sunday . `` There was not one decision we made that was based only on witness testimony . '' Jury foreman Paul Connelly said some of the prosecution 's witnesses did n't seem trustworthy . At least three former Simpson co-defendants who cut deals to testify in the case had criminal records . Asked whether the jury trusted the witnesses , Connelly answered : `` Not entirely , no . '' Watch jurors explain their verdict » . Prosecutors produced an audiotape of the confrontation in which authorities said Simpson and five men burst into a Las Vegas , Nevada , hotel on September 13 , 2007 . The men allegedly made off with pillowcases containing Simpson sports memorabilia . Several jurors said audiotapes of the incident and conversations between Simpson and others that were recorded surreptitiously before , during and after the heist made the prosecution 's case . `` It would have been a weak case '' without the tapes , juror Dora Pettit said . The jury of nine women and three men found Simpson and co-defendant Clarence `` C.J . '' Stewart guilty Friday of 12 charges , including conspiracy to commit a crime , robbery , assault and kidnapping with a deadly weapon . Simpson , 61 , could get life in prison . Sentencing is scheduled for December 5 in Las Vegas . Prosecutors alleged that Simpson , a former football star , led a group of men who used threats , guns and force to take the memorabilia and other items from memorabilia dealers Bruce Fromong and Al Beardsley . Four men who had been charged with Simpson cut deals with the prosecution and testified against him . One testified that Simpson instructed him to bring a gun to the hotel encounter . `` Everything was based on the recordings , '' juror Dora Pettit said of the panel 's decisions . Simpson , who did not testify during the trial , told police he did n't know the people with him were armed . He also claimed the items had been stolen from him , and the hotel encounter was just about him retrieving his items . Simpson 's lawyer has indicated he plans to appeal the conviction , partly because some of the jurors had indicated during jury selection that they disagreed with a 1995 verdict in which he was acquitted of killing his ex-wife , Nicole Brown Simpson , and her friend Ronald Goldman . Watch Fred Goldman hail the verdict » . Teresa Owens , one of the jurors in the Simpson robbery case , said any suggestion that the jury found Simpson guilty because of the verdict 13 years ago is `` terrible . '' `` There 's reports right now that we 've had some kind of vendetta against Mr. Simpson for ... 13 years ago , '' she said . `` That in no way had anything to do with this case whatsoever . '' Connelly said the murder trial `` never came up . '' `` I do n't think it was on anybody 's minds . For that , I can say I 'm proud of the jury , '' he said . Before the robbery and kidnapping trial , the jurors promised they could disregard Simpson 's past and solely consider the evidence against him and Stewart , 54 . Owens also said it would be `` preposterous '' for anyone suggest that the makeup of the jury -- 11 jurors were white , and one said she was Hispanic , while Simpson is black -- hurt the defense 's chances . `` They chose us . Five hundred people ... filled out these questionnaires , '' Owens said . `` They had the [ opportunity ] to pass us . '' Pettit said the jury has been painted by some `` as an all-white jury that hates O.J . '' `` That 's just not true , '' she said . `` It could n't be further from the truth . '' Asked whether they felt the crime was bad enough to warrant life sentences , Connelly said that was up for the court to decide . Pettit said that `` if he walked out tomorrow , I 'd be fine with that . '' However , she said Simpson had to be found guilty and that his argument about just wanting to recover his own things did n't work . `` Under Nevada law ... even if you 're recovering your own stuff , you ca n't do it in the manner that they all went in and did it , '' Pettit said .
Some witnesses did n't seem trustworthy , jury ##man says . At least two witnesses who cut deals to testify had criminal records . ` ` Not one decision '' was made based solely on testimony , he says . Jurors : Simpson 's 1995 acquittal on murder charges never came up .
