Attorney: McAfee rushed to the hospital

Story highlights

An attorney says John McAfee had a nervous breakdown, but no heart problems

The 67-year-old software company founder is back in immigration detention

Guatemalan officials say they've rejected McAfee's request for asylum

McAfee's attorneys request an injunction, saying "due process has been violated"

Guatemala City CNN —  

Software pioneer John McAfee ended the day Thursday as he started it: imprisoned in a Guatemalan immigration detention center.

Earlier, a neon green ambulance had whisked the 67-year-old to a police hospital just hours after officials rejected his bid for asylum. McAfee’s legal team said doctors were treating him for cardiovascular problems.

Later, attorney Telesforo Guerra offered a different diagnosis: McAfee had suffered a nervous breakdown, but tests showed he did not have heart problems.

The series of events were the latest dramatic twists in a saga that reads like a best-selling mystery, with poisoned dogs, a dead neighbor and international intrigue fueled by weeks on the run.

The next chapter could unfold in Belize, where Guatemalan officials said they were preparing to deport McAfee after rejecting his asylum bid.

Police in Belize are ready to meet McAfee at the airport if he’s deported, spokesman Raphael Martinez said.

Authorities there have said they want to talk to McAfee about the November 11 shooting of his neighbor, American businessman Gregory Faull.

Under Belize law, McAfee can be held for 48 hours without charges, Martinez said.

But McAfee’s fight to stay in Guatemala isn’t over.

His attorneys said they filed a request for an injunction with Guatemala’s Supreme Court.

Standing outside the police hospital, attorney Karla Paz said officials had rejected McAfee’s petition without weighing the evidence.

“Due process has been violated,” she said. “The right to defense has not been respected.”

Guatemalan authorities took McAfee into custody Wednesday on accusations of entering the country illegally.

After weeks in hiding, the anti-virus software company founder had emerged publicly Tuesday in Guatemala’s capital, hundreds of miles from the Caribbean island in Belize where the body of his neighbor was found.

McAfee had sought asylum in Guatemala, arguing that he left Belize to escape police persecution.

But Guatemalan authorities found there was no basis for his asylum request, presidential spokesman Francisco Cuevas said Thursday.

McAfee founded his computer security software company – McAfee Associates – in 1987, initially running it from his home in California. Seven years later, he sold his stake in the company. He moved to Belize in 2008.

On November 9, he told police someone poisoned four of his dogs. To put them out of their misery, he shot each in the head and buried them on his property, a former girlfriend said.

The dogs’ barking and aggressive behavior had been a source of friction between the neighbors.

Two days after the dogs were poisoned, Faull was found fatally shot in the head.

McAfee has said he had nothing to do with Faull’s death, and Belize authorities are out to get him because he refused to pay a bribe to a politician months earlier.

Belize police say they only want to talk with McAfee.

“He’s really gone out of his way to make the country look bad,” Martinez, the police spokesman, said earlier this week, “and we just believe he should, if he’s innocent as he’s saying he is, he should bring in his lawyer, and let’s get to the bottom of this and say what he needs to say and let’s move on.”
