The next stop for software pioneer John McAfee could be Belize after Guatemalan authorities rejected his bid for asylum.

Authorities there want to talk to him about the November 11 shooting of his neighbor, American businessman Gregory Faull.

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

But McAfee's fight to stay in Guatemala is not over.

His attorneys said they filed a request for an injunction with Guatemala's Supreme Court to prevent his extradition.

Standing outside the police hospital as ambulance lights flashed nearby, attorney Karla Paz said officials had unjustly rejected McAfee's petition without weighing the evidence.

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

McAfee is being held in a Guatemalan immigration detention center while developments swirl.
