Four poisoned dogs. A dead neighbor. A millionaire on the run.

Come Thursday, deportation may be the latest twist to the saga of software mogul John McAfee.

McAfee , who was on the run for weeks to evade questioning in his neighbor's death, was detained in Guatemala on Wednesday after entering the country illegally, officials there said.

He may be sent back to Belize on Thursday so officials there can question him, said Francisco Cuevas, a spokesman for Guatemala's president.

For those following the tale of McAfee, the man who amassed a fortune by running and then selling an antivirus software company named after him, this new twist should come as no surprise.

His arrival in Guatemala is the latest scene in a true story that reads like a Hollywood tale.

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.

Three people have been detained for questioning in the killing, police have said, and investigators are pursuing multiple leads.

"I had nothing to do with his death," McAfee wrote on his website Tuesday in a message to Faull's family. "I have lost five close family members in my 67 years and I know your suffering."

UPDATE: The latest post from his blog:

My lawyer just brought a judge to the jail and the judge issued a stay order until a higher judge can review the case.  This effectively stops Immigration from returning me to the Belize border.  So….. the urgency is eased a bit.
