suggests that he's insane. Matt gutman, abc news, san pedro, belize. Let's bring in nancy grace. Dan abrams, "gma" legal correspondent. Good morning to both of you. Good morning. Good morning. WE JUST HEARD, McAFEE HASN'T Been charged with a crime. He hen named as a suspect. At this point, is it just a formality? Of course, he's the main incident. You have a motive. You have the incident with the dogs. You have a history. And relationship that they had. And now, he's on the run. The authorities are saying publicly, come on. We just want to talk to him. Just come on in. We just want to have a little chat. Of course, the reality is he is now the prime suspect. Reporter: Nancy, mcafee says he's innocent. He's blaming the police for the alleged poisoning of his dogs, not the victim. What evidence do police have against him? Well, actually, they've got quite a bit of circumstantial evidence. A U.S. REPORTER WAS in McAfee's home recently. And sitting out on the dining room table during the interview is a lugar 9 millimeter weapon. The victim, gregory faull, the next door neighbor, lived about 300 yards away, was killed with a 9 millimeter weapon. And on the floor was a lugar ammo shell casing. Whoever killed him also took the victim's iphone and his laptop. Now, why would they do that? Possibly to get rid of evidence of angry exchanges between the two. And before the neighbor is made out to be a zany coot, other neighbors complained about this pack of dogs and the security guards, as well. An interesting fact, the thursday before the dogs were allegedly poisoned, you see McAFEE WITH THE MAYOR OF SAN Pedro, at a formal event, where he donates, handcuffs, tasers, batons, to the police. But suddenly, he says he is the victim of some vendetta. And interesting thing to note, in belize, which was formally under great britain rule, they no longer have a jury trial. They have a constitutional amendment taking away jury trials in murder cases. He'll be before a judge. McAFEE HAS BEEN CHARACTERIZED As paranoid, bonkers, delusional. How does that factor into this case?Ou heard hsked there in the taped piece. He's saying he's not, in effect, insane. But there is a lower standard for insanity in a defense in belize and here in the united states. Tougher to claim insanity here than there. With that said, we're not there yet. He hasn't even been arrested yet. And let's keep in mind. People are going to say, if he had been in this country, he would have been charged already. He would be named -- I don't think that's true. While nancy lays out some of the evidence they have against him, still need to build a case against him. They need to get some comments from him. They need physical evidence. This is not an open-and-shut case. And he's commenting to the media. He has talked to "wired." He was talking to matt gutman. What is going to undo him? He's breaking the cardinal rule of criminal defense, don't talk. He talked to you guys. He talked to cnbc, "the wired," the a.P., He can't shut up. He says he's not crazy. But it's like taking out a billboard on madison avenue, i didn't do it, when nobody says you did. He dyed his hair, his mustache. He's hiding in the sand with a cardboard box over his head. He's acting guilty. He may try to leave the island. There's nothing worse you can do when the authorities want to talk to you, not just to run away. But to then runaway and talk to everyone about running away. And talk to people, the authorities -- the authorities want to hurt me. The authorities want to kill me. And dye your hair, dan. The good news is, if the authorities had wanted to kill him, with all of this media attention, they're not going to do anything to him now. You're safe. You can come in. You can talk to them. They won't get a chance to do anything to you now. What I don't understand, dan, why they can't find him. It's 68 miles by 180 and they can't find him? We'll keep you updated. This case has legs. Time, now, for the weather and sam champion. Sam?
