New Delhi, Feb 18: Osama bin Laden's latest hideout could be Parachinar, a tribal city in Pakistan bordering Afghanistan, say American geographers. The tracking is based on two geographical theories, 'distance decay theory' and 'island biographic theory'. According to their 'distance decay theory' a person is more likely to be found closer to where he or she was last seen. Also their 'island biographic theory', states that a place with more resources for survival attracts the fugitive.
The last known location of Osama was Tora Bora of Afghanistan.
The researchers have listed some details about Osama that includes housing needs:
* Osama's height: 6'4'' feet * Medical condition: he will need regular dialysis. So, he would need electricity to run the machine. * His Security: Laden will need a fortified building in an isolated place with an overhead cover to shield him.
