Mcafee antivirus so viruvirus answering hard questions about what happened after those millions. At a time when everyone is focused on computer hacking, hes front and center again. Bull for a man whose every move was once on camera, what happened during those mysterious off the radar years . When the larger than life character was suspected of taking a life . Matt gutmans been following him for four years to find out. Reporter there are so many layers to the epic disturbing story of john mcafee, maybe because there are so many john mcafees. John mcafee is one of the wildest characters youll ever come across. The reporter theres mcafee the party animal. John . Reporter mcafee, the Silicon Valley gazillionaire. Hes someone that i feel is dangerous. Reporter even mcagree the president ial candidate. Stand with me to protect our freedom. Reporter pinning down the truth in mcagrees life story is never easy, because often, it is as slippery as he is. He is like teflon, nothing sticks to the man. Reporter if the name mcagree rings a bell, it should. Theres a good chance its on your home computer screen right now. Yep, hes the guy behind the famous mcagree antivirus software. We say were going to talk tomorrow, does that mean face to face . I first crossed paths with mcagree in 2012 when hed become even more famous south of the border. He was on the run and would only talk to me by phone. You may think that youre not being followed, but i can assure you you are. Reporter hello . But i wasnt chasing him around late M Latin America because of a cyber crime, but allegations that he murdered fellow american greg fall. We begin with that software millionaire on the run. Reporter Police Wanted to question mcagree about the murder, but he didnt want to answer. He dodged authorities all the way back to the u. S. Where he has been ever since, never charged with a crime. The pandoras box has been opened. Reporter but what makes this story even stranger is john mcagrees latest incarnation. Our computers are no longer back in our office, they are in our hands. Reporter these days, hes reemerged also a prophet of digital doom and his warnings about Cyber Threats attract plenty of eyeballs both in person and on tv. Were being spied on by our government. Reporter even with all that attention, what he hasnt done since returning home is a no holds barred interview on every aspect of his past. But now, after more than four years, im about to get my chance. I admit, ive heard so many things about him. Hes erratic, hes a high tech prince of darkness. Hes just plain dangerous. That im nervous. Ive been worried about john mcagree. Im keeping my second cell phone and my credit cards here at the hotel so they dont get hacked. I drive onto our meeting place, a parking lot in rural tennessee, where mcagree greets me like a southern gentleman. How are you doing . Good to see you. Reporter how are you . We talk a bit and head off in his tanklike truck. If i have to put up with people like this, then im going to have fun doing it. Reporter to him, reporters a ball of twine to a cat. Something to play with until he gets bored. We arrive at a quiet suburban downtown for a casual lunch at this mexican restaurant. Yeah, i like mexican food, sure. Said you grew up in a town like this in virginia, right . We talked about his troubled childhood. One of the things that was not idyllic there was your father, you said that he was a raging alcoholic, that he was abusive to you and to your mother . Yeah. Nobody has an ideal life. Even children. Reporter he died when you were 15 . 15. He shot himself. Reporter he shot himself . Yeah. People always look to the past to explain the present. Doesnt work that way. Reporter the present for mcagree, this upscale but hardly lavish spread. He shares it with his new wife, janice, his ever present body guard and his dogs. As we sit down inside, fortified by a glass of expensive scotch, mcagree continues with his life story, saying that despite being a lazy kid, he always got straight as. Math came easy to me. I never studied. I just did what i felt like i should do. Reporter in college, mcagree says he began peddling a product he knew he could sell. Cocaine. It is interesting that drug dealing was really your first foray into entrepreneurship. Yeah. Well, as it is its entrepreneurship. Its everything. Its salesmanship. Reporter then came the dawn of the gogo 80s. Our lips are sealed reporter big hair, even bigger shoulder pads. Pacman fever. As the home computer revolution kicked in, mcafee now working as a programmer was among the first to identify its perils and a potential profit. A computer virus is a programmer written by a hacker with a unique purpose. And that purpose is to multiply and live. I was speaking out, oh, yeah, i can stop this here, i can do this, i can remove the thing. And wrote a program in a day and a half. Reporter so, mcafee was created in a day and a half . Yes. Reporter how well did it work . 4 Million People were using it within a month. Five years later, over half the fortune 500 companies in america were using it. Thats how important it was to their business. Reporter in no time, the software bad boy amassed a fortune. After a few years, he cashed out. You made 100 million from selling mcafee, right . Thats what they say. Reporter how much did you make . Much more. Reporter what did you do with the money . I wasted it. Reporter he built nine homes, filled them with expensive art. Filled them with antique cars. Is that love . Isnt it selfishness . Reporter his next chapter, creating a yoga retreat in colorado, reinventing himself as a new age guru but stowing his eternal wisdom on his guests. Its all about need. And jealousy is all about the fear of losing all of these there sant things which you obtained. Reporter but mcafee says his zen was disrupted by what calls prfrivolous lawsuits. In 2009, mcafee let it be known he lost most of his money. How to kiss nearly 100 million goodbye. Sometimes a little bit of pain is necessary to see and understand the true circumstances of your life. Reporter nightline covered this auction on mcafees ranch where everything, including his beloved airplanes, exotic art collection, even the gold elephant and dinosaur skull went on the block. 1 million. Reporter mcafee claims it was all a charade, a ruse. He was just trying to look broke so people would stop suing him. No, i didnt lose my fortune. Im not that stupid. Reporter whatever the case, one part of that report is indisputable. Now, mcafee plans to take his remaining handful of millions and head to central america. Reporter next stop, belize. He figured, no one would sue him there. Mcafee hassen eluding police. Reporter but he probably never imagined hz time in the tropical paradise would make him an international fugitive. Stay with us. Once again, we return to 20 20. Heres matt gutman. Reporter here at chez mcafee, the scotch is brought in by the case. And champagne is waiting as usual. Reporter champagne is on ice. Excuse me for smoking, people. But its one of my vices. Reporter cigarettes are always ablaze. And the guns are always loaded. This is at 1,300 feet per second. This is 800 feet per second. Reporter so which would hurt more . Oh, this, absolutely. Reporter but im not here for a party or target practice. Im here to talk to him about how his life took a very dark turn during his Central American interlude. Why did you go to belize in the first place . Well, because, im a stupid man. Reporter easy to joke now, in his pleasant suburban kitchen. But back in 2009, before everything went so horribly wrong, belize seemed a brilliant idea for john mcafee, who was eager to escape the cascade of lawsuits back in the u. S. Most beautiful beach in the world, a reef a quarter of a mile offshore. I snorkel, i fish, i swim. I love the water. It was beautiful. Reporter the quintessential millionaires dream. He purchased a spread on an island called ambergris caye, surrounded by american expats. But mcafees most intriguing fantasy wasnt on the beach at all. Get ready for some serious heart of darkness here. Reporter as seen on this cnbc report, he purchased a Second Property in the interior of the country and moved deep in the jungle to a place called orange walk, where he had set up a lab. I thought, wow, this is a dream come true. Reporter Allison Adonizio was a harvardtrained microbiologist he brought into the jungle. The famed entrepreneur was at it again with his latest startup venture, creating plantbased antibiotics. But she says the enterprise fell apart when her benefactor started to come unhinged. He became very paranoid, he was talking about taking over the country. I started to think, this guy is a madman. Reporter mcafee says he was helping the locals, feeding poor families and providing many with jobs. I employed half of the town. I can show you a letter from the mayor, saying that mr. Mcafees done more for orange walk than any of our citizens have. Reporter but exactly what was he doing for those citizens . Mcafee admits he brought in young women to be in his harem. Then there was the gang of convicted criminals mcafee proudly says he hired as his armed bodyguards, his own private militia. Everybody i hired was an exfelon and had spent half of their life in prison. Reporter it sounds like thats a recipe for disaster. They never shot anybody. Never even pointed a gun at anybody because they were dangerous people. He called them hitmen. He told me repeatedly that he could have people hurt, taken out if he wanted to. Reporter adonizio says it all became too much for her. But listen to her traumatic account of what she says happened when she told mcafee she wanted out. When i did go over there, the conversation did not go as i expected. And oh, god, i feel so stupid. Reporter she wasnt able to go on. Im sorry, i just reporter the one time she was able to describe publicly what she says happened was in a documentary film about mcafee called gringo. I told him i had a headache and he went into the other room and he brought me two pills and a glass of orange juice. It tasted foul. Reporter she says he drugged her with that juice and then raped her. I only have sort of flashes of recollection, he was standing over me naked. I grabbed my clothes, i dont even remember taking them off. Reporter adonizio says she quickly fled belize without telling the local police. She says u. S. Authorities told her they had no jurisdiction, so no charges were pursued. I dont know what to tell you except that i have emotional and physical scars from that experience. Allison adonizio, a madwoman. Reporter a madwoman. A madwoman. Reporter well, she claims that you raped her. Drugged her and raped her. Well, she can claim whatever she likes. Never had sex with her, certainly never raped her. She seemed rational. She was not. I find it rather ironic that somebody as unhinged as mcafee would say that im unstable. I think that im pretty strong, considering everything that ive had to go through. Reporter then, in april of 2012, mcafee was about to have trouble with the law for an entirely different reason. There was a belief he was manufacturing illicit drugs in the compound because of all the different criminal elements that were there. Its very unusual that you would be doing research into plants and you need so many people to protect you. Reporter belizes gang suppression unit raided his lab, they say on suspicion he was making meth. No drugs were found. Police reporter mcafee claims the goth was harassing him because he wouldnt pay bribes. I was on the verge of something. When i refused to pay an extortion for 2 million and a week later, the gang suppression unit destroyed my lab. Reporter mcafee abandoned the jungle and moved back to ambergris caye. But trouble followed. Among his neighbors was this man, greg faull, a builder who came from Central Florida to central america. This is the house in belize. Took him about seven years to build it. Reporter gregs mother Eileen Keeney says her son wanted a peaceful retirement in the caribbean but when she came to visit him a few months later, she says it was anything but peaceful. Greg was not happy with him, and he had had some issues with mcafee. Reporter keeney says her son greg was disgusted by what mcafee had brought back from the jungle. That harem of women, the armed guards, and especially the swarm of dogs that constantly menaced passersby. He said, now, were going to be walking past mcafees house and theres going to be dogs there. Now, theyre usually fenced up, but he says, i just want to warn you. Reporter as keeney headed home to florida, she had no clue what was ahead. Two days later, she received an unfathomable phone call from her daughter. And then she told me gregs been murdered, and i let out this bloodcurdling scream. Reporter a brutal beachside murder. Was the eccentric millionaire involved . I have a couple more questions. Coming up, when we press him, we discover that is a touchy subject. Nothing happened. Goodbye. Reporter youre walking out on this interview . [ bleep ] yes, because you have not kept your [ bleep ] word. Reporter stay with us. The Apartment Building where the fire was. When things like this happen, i think you find a new perspective on life. Hi. Red cross put us in a hotel so we were able to stay together. Were strong and, if we overcame that or if we can overcome that, we can overcome anything, so. [ sniffle ] reporter november 2012. Trouble is brewing in belize. American greg faull has had it with his neighbor john mcafees pack of aggressive dogs, and he told friends he was going to take care of the problem. Greg had told him he was going to poison the dogs. Reporter then, one evening, some poisoned meat is thrown over mcafees fence. All nine of his dogs are poisoned. Gregory faull complained about mcafees dogs, and shortly after, the dogs are poisoned, and they die. Reporter the very next night, an intruder sneaks into faulls home, tasers him several times and then shoots him in the head. No one had confronted mcafee and faull did. You see, theres a linkage there. Reporter the house showed no sign of forced entry. Nothing was taken from inside. He was brutally murdered and he had no enemies. Reporter but belizean journalist jose sanchez says his country is notorious as a place where just about anyone can get away with murder. Unless there is an eyewitness to a crime, murder is rarely solved in belize. And that is the reason why there is a 3 average conviction rate. Reporter still, Belize Police quickly name mcafee as a person of interest in faulls murder. And because of that famous name, seen on millions of computers worldwide, the story makes international headlines. On the run from police in belize. John mcafee has been marked. Reporter police want to talk to mcafee, but the feelings not mutual. Even as the news of the murder breaks Police Launch a fullscale search. Reporter mcafee goes on the lam. Of course hes the main suspect here. Youve got motive, youve got the incident with the dogs. Youve got their history. Why would you go to the effort of hiding if you werent guilty . Reporter why did you go on the run . Because if i didnt go on the run, id be a dead man now. Reporter mcafee claims that after he refused to pay bribes, the belize government was out to get him, and the poisoning of his dogs and the murder of faull was somehow just part of that sinister plot. If you think they do not do this, then you are seriously naive and again i want to talk to the audience. Please, people, even in television you see this happening constantly, all right . And some part of that television or the movies, some part of it is probably true. That allegation that he makes, that the government killed his dogs, and the government killed faull, because he wouldnt pay bribes. Its utter nonsense. Reporter the belizean government wouldnt comment on mcafees accusations, but many, including the prime minister, called him crazy. It strikes me that hes extremely paranoid. In fact, i would go so far as to say bonkers. Reporter but bonkers or not, belize couldnt catch him. Safety first. Thats when i started on his trail. Abc news matt gutman is in belize with the latest. Reporter from just outside john mcafees compound, its owner this morning is on the run. Were you guys scared . Yeah. This is isla bonita. This is paradise. Things like this dont happen around here. Reporter three weeks underground, all the while calling in to u. S. Journalists. John mcafee is joining us now by telephone. My life has become a little more intense. Im going to ask you some questions reporter including me. Youre sincerely concerned if you somehow wind up in their custody, theyre going to assassinate you . Absolutely. Reporter why were you contacting journalists while you were on the run . It seems like a bad idea, if youre trying to stay hidden. No, it was a really good idea. Reporter why . As long as the world was paying attention, they couldnt actually shoot me in the street. That story continues to get even more strange by the hour. Reporter strange indeed. He finally surfaced across the border in guatemala. Thank god i am in a place where there is some sanity. Reporter where we met face to face for the first time. How have you been . Really good since i got here. Reporter he told me his great escape involved everything from burying himself in the sand, to a series of elaborate disguises. And i had a cane, and i was walking like this, and i had my jaws stuffed with toilet paper. Reporter he was hoping for political asylum. But instead, just a few hours later john, where are you going . To jail. Reporter vice tv filmed him being arrested, as guatemala prepared to deport him back to belize to face questioning. His attorney has been arguing all along that any move for mcafee back to belize could risk his life. Reporter but before they could put him on a plane, mcafee collapsed. An ambulance rushed him to the hospital with a media horde following behind. But miraculously, mcafee opened his eyes and asked the nurses not to undress him in front of the cameras. Not in front of the press, please. Reporter you faked a heart attack. Sure, i faked it, what would you have done . Reporter the whole charade lasted just long enough to allow his lawyer to file an appeal. John mcafee has been granted a stay of deportation to belize. Reporter mcafee outfoxed belize, again. In the meantime, mcafee will have to wait in this lockup full of south american migrants until the high court here can decide his fate. From inside that facility, he still managed to tap out messages to the world. I apologize for the format of this conference. Our intent is to return to america if at all possible. Reporter and lo and behold, thats exactly what happened. Theres nothing i can say, i dont know what im doing, im going to miami. Reporter guatemala authorities deported mcafee to miami. I had no choice. They put me on an airplane, i am here. Reporter there, he escaped reporters in this van. I was again able to run him down, and a little while later we sat down at his hotel. How would you characterize
