>> reporter: no, she didn't rule. this is a hearing that had gone on for three days listening to expert testimony from the defense and prosecution. it means that the trial is still going to go forward. jury selection will begin on monday. at least that according to judge nelson. i had a conversation with the defense attorney mark oma are a. he said he's put in for a last minute motion to try to delay the trial. he believes they still have other material that needs to be worked through. they need to go through before they are ready to begin. the judge seems adamant the trial will begin on monday. i asked mark o' mara what type of jurors he wants seated for the trial. here's what he said? >> i want open minds. people who have not made up their minds and people who are strong enough to di side the case on the facts and law and not external public pressure. my concern is we have so much pressure that any verdict, whatever it might be, might not be accepted as the proper one. >> the belief is that the jury selection could take a week or weeks according to the defense team. nelson mandela hospitalized. we'll go to south africa for the latest next. ♪ this is the tempur-pedic innovation lab. it's like a front row seat to our latest technologies. here is where our engineers do their constant improving. we have helped over 7 million people fall in love with their tempur-pedic. and now for my favorite part of the tour.
