Widely circulated video footage of Muammar Gaddafi’s capture—during which he was alive—has sparked international interest in who, exactly, killed the long-time Libyan dictator and how. Libyan authorities will now launch an investigation aimed at answering these questions. The country’s current leader suggests it was Gaddafi’s supporters—not his opponents—who would have been motivated to kill him. His enemies would have preferred to see him tried and punished for his crimes, he said. No word yet on who will carry out the investigation.
