May 3rd 2010, Pat Brown had this to say.
Pat Brown, a criminal profiler, said on "The Early Show" Monday that a combination of factors has contributed to where things stand in the McCann case.
"(One theory) was that the child was abducted. And another theory was that she died in the apartment, and this, of course, is the theory the McCanns aren't too happy about. And they don't want that one out there," Brown said.
"And so they're still angry at the Portuguese police. And this is one thing I don't think they should bring up at this point in time. After three years when they're looking to get the cooperation of the police, it's not the time to say, 'You're not following up our leads.' And they also mentioned that it's possible they aren't following up the leads because they don't want the child to be found alive, because that would be embarrassing. Not what you want to say. You want to keep it positive and ask for somebody's help and not bring anything negative into the conversation."
As for the McCanns' supposed leads, Brown said she hasn't heard of any actually getting anywhere.
"Ever since the very beginning, when they have believed that the private investigators had great leads that weren't being followed up on, I never saw that they panned out to be anything. And they're saying that there's other leads that aren't being followed up, and I don't know what those are, and I don't think anybody really does. I don't know what leads they could be finding at this point in time."
Brown added, if the McCanns are innocent of any wrongdoing, they will continue to search for Madeleine.
"They're always going to believe their child is out there. That would be normal for any parent whose child has gone missing. They're not going to give up on her. So they're doing the right thing in the sense that they're trying to keep her in the public eye."
However, Brown added, "Quite frankly, this child has been seen everywhere. I mean, as far as missing children go, she's one of the most publicized missing children in the world. So that's one of the most unusual things about this: With her picture out as much as it's been out there, she would have to be pretty well hidden for her not to have shown up at this point."
