Antivirus software pioneer John McAfee, released from a detention cell in Guatemala and sent back on a plane to the U.S., landed in Miami on Wednesday night and was promptly escorted away by U.S. federal officials, according to ABC News. As ABC News reporter Matt Gutman explained:

It was not clear whether officials intended to help McAfee avoid the inevitable media circus or wanted to question him. However, he has not been charged with committing a crime in Guatemala or Belize, where the authorities have sought to question him about the murder of his neighbor.

McAfee's current whereabouts aren't known at this time.
