Osama bin Laden is most likely hiding out in a walled compound in Parachinar , according to a satellite-aided geographic analysis released today. A research team led by geographer Thomas Gillespie of the University of California-Los Angeles used geographic analytical tools that have been successful in locating urban criminals and endangered species. Basing their conclusion on nighttime satellite images and other techniques, the scientists suggest bin Laden may well be in one of three compounds in Parachinar , a town 12 miles from the Pakistan border. The research incorporates public reports of bin Laden 's habits and whereabouts since his flight from the Tora Bora region of Afghanistan in 2001.
