a month ago, police acting on an unrelated lead dug up a basement looking for patz's body. while that lead didn't pan out, the publicity surrounding it prodded lopez and other family members to come forward. >> to do the right thing, to confess and get this thing over with. >> pelley: so, john, where does the investigation go from here? ta reporter: well, they're going to go back and talk to those ilmily members and find out how many family members he said it to, how many times, what exactly did he say, over what period of years. it's interesting, though, our producer there who's been talking to the brother-in-law had a conversation with him today where he said "in your mind, is there any doubt he's the killer?" he said-- and i'm quoting now-- "no doubt about it. he said he did what he did." he asked was it a relief for him and the family and he said "for him, everyone, and everyone in the family." >> pelley: that's what the brother-in-law said?

>> i think the... that, in fact, there is an understanding between the united states and israel that the diplomacy should eporllowed to play out. >> reporter: scott, there also seems to be an understanding that, if diplomacy ails, the u.s. will join israel in striking iran. >> pelley: david, thanks very much. in egypt, two of the most polarizing candidates will square off next month in the presidential runoff. ti took a revolution to allow egyptians to hold their first free election in their history, but they have chosen two candidates who are throwbacks to old egyptian politics. on one candidate is from the popular muslim brotherhood movement, which advocates r lamic law. the other is a former general who was the last dictator's prime minister. ne secular military versus islamic fundamentalism-- almost as if the revolution never happened. at the end of the first week of trading, facebook has made very few new friends. investors who got in on the initial stock offering saw the stock fall from its debut price of $38 to just under $32 today. cke only thing that rose was anger over the handling of the offering by the nasdaq stock exchange. anthony mason has more on that. >> reporter: the technical glitches that marred facebook's a foet debut a week ago cost one company a fortune. you lost $30 million because of $is?
