>>> they trickle in by ones and twos, mostly only staying enough to get a tan and go home, but a with more money than they can spend or perhaps more personal seems like it's fiction. i mean, it doesn't seem real.
>> because shane and brittany mccann make their living managing the properties of those that live here they're pretty plugged in. they knew john mcafee and greg faull so it seemed logical to continue our search for clues in this case with them.
>> the police department has been tight-lipped.
>> no ballistic reports and no crime scene investigation and no toxicology on the dogs that had been poisoned.
>> but the police must know a lot more than they're saying publicly because he personally found something in greg faull's house that spoke to the issue of motive. it was a powerful poison called feridan.
>> it was found in the trash can. i found a green paper plate that he had taken an old tortilla bread and rolled it up into it.
>> based on that, shane mccann believes greg faull fed those dogs poisoned tortillas, and just spiegel and his wife vivian say they can add two and two as well as any detective.
>> did john have the means to do this? john had the means to do whatever he wanted. he still does. was there a motive? it's pretty conclusive that the night before he was murdered that greg poisoned john's dogs. that's not speculation. that's fact.
>> he wanted everyone to know that he poisoned those dogs.
>> but from his secret hideaway, john mcafee told reporters he didn't believe that. it was the government, mcafee claimed, who poisoned the dogs. as for the murder mcafee insisted he had an alibi. he was at home with witnesses on the night greg faull was killed, he said.
>> i was home with samantha and another person on the property.
>> wherever he was then, the police apparently had no clue as to where he was now as he hammered away at the police and the government of belize .
>> the gang suppression unit, i think if you do that you will see the position that i'm in, and you will understand my reluctance to turn myself in.
>> which, to the neighbors, seemed to describe a country they didn't know.
>> he's saying terrible things about belize , what's that like to hear?
>> you tell me. does it make sense to you?
>> does it make sense to you?
>> if belize was sch a horrible, dangerous, corrupt country, would i be sitting with you right now talking?
>> so many questions. topping the list for the friends of greg faull was why were the police backing off the earlier claim that mcafee was a suspect in the case? police spokesman rf ale martinez.
>> he isn't a suspect, and i want to make that clear that we don't label him as a suspect at this time. he is a person of interest. he is wanted for questioning because there is nothing at this point that ties him to this murder.
>> would it be, some wondered, that mcafee's generous gifts to local police over the years had something to do with that determination?
>> this is a stun gun. i donated over 100 of these. if you do get touched by this it will knock you down, but you will not be harmed unless you hit your head or something in the process.
>> that was john mcafee present the san pedro police department with taser, flashlights just two days before greg faull was killed. the newspaper woman told us mcafee's larges for the local police w police .
>> why was he so interested in donating to the police department ?
>> our police department is underfunded and i think that he felt that that was one of the most effective ways for him to contribute is by helping to support our local law enforcement.
>> seemed strange now that john mcafee was so publicly hiding from the very police officers he'd helped equip. the ex-pats just wanted mcafee, wherever he was to stop talking to reporters and start talking to investigators about the murder of greg faull.
>> it's just really frustrating that at least if the police wanted to ask you questions why not just answer it? i mean, just -- to put everyone's minds at rest.
>> and the tragedy is someone died and it's kind of like, now it's turn into this circus act.
>> no question. this case had now become a media circus . the traveling kind with reporters from all over the world taking turns under the big top . all of us, vying for a shot at finding the ringmaster in what was fast becoming the weirdest show on earth.
>> coming up --
>> did he disguise himself?
>> a lot.
>> nobody recognized him.
>> a girlfriend with a new tale to tell.
>> and a new cry for help from a grieving family.
>> he was brutally, cowardly murdered and i would like to see some justice done.
>> when "dateline" continues. hmm, we
