John McAfee, the antivirus software pioneer , has "suffered two mild heart attacks," Reuters reports.
McAfee, 67, was taken to a hospital in Guatemala after having convulsions, according to CNN.
The Associated Press, however, reports that McAfee was suffering only from "high stress"
McAfee is wanted in Belize for questioning in in connection with the death of his neighbor there. He has been on the run for weeks and was detained in Guatemala on Wednesday on suspicion of entering the country illegally, officials said.
His lawyer, Telesforo Guerra, filed a formal request for asylum with Guatemalan officials Wednesday.
The case began to unfold on November 9, when McAfee told police someone had 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.
Officials say the dogs' barking and aggressive behavior was a frequent source of friction between McAfee and his neighbor, American businessman Gregory Faull.
Then Faull turned up dead -- two days after the poisoning -- with a gunshot wound to the head. He was in his own living room.
A 9 mm shell was found on the second step on the first floor, and Faull was found dead on the second floor of the home in a remote area of Belize.
Authorities in Belize have wanted to question McAfee about the death. He refused and then went into hiding.
Despite his disappearance, McAfee, 67, has remained in contact with the media, through this link providing a stream of colorful bulletins over his predicament, state of mind and his claim that Belize's authorities want to kill him
