The hunt for Gaddafi continues

As anti-Gaddafi forces battle for control of Sirte, many are speculating about the fallen leader's whereabouts.
National Transitional Council Commander Ismail Al-Salabi.
SOUNDBITE: ISMAIL AL-SALABI, COMMANDER OF NATIONAL TRANSITIONAL COUNCIL (NTC) FORCES IN BENGHAZI, SAYING:
"I am personally convinced that Colonel Muammar Gaddafi is out of Libya because Muammar Gaddafi has no courage to stay in Libya - not him, not his sons. Maybe some of his sons are trapped under siege and cannot leave but Gaddafi, I am personally convinced, that he went out of the country even before his family departed."
Another military official believes nomadic tribes along the Algerian border may be helping hide Gaddafi.
There are reports that Gaddafi's sons are still in Sirte -- the family's hometown now under siege by NTC forces.
Gaddafi's daughter, brothers and their mother fled to Algeria in August.
