Where's bin Laden? Science may hold the answer

— -- Fugitive terrorist Osama bin Laden is most likely hiding out in a walled compound in a Pakistani border town, 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.

The results, reported in the MIT International Review, are being greeted with polite but skeptical interest among people involved in the hunt for bin Laden, the al-Qaeda leader behind 9/11. Bin Laden's whereabouts are considered "one of the most important political questions of our time," the study notes.

"I've never really believed the sitting-in-a-cave theory. That's the last place you would want to be bottled up," Gillespie says. The study's real value, he says, is in combining satellite records of geographic locations, patterns of nighttime electricity use and population-detection methods to produce a technique for locating fugitives.

Essentially, the study generates hiding-place location probabilities. It starts with "distance decay theory," which holds that the odds are greater that the person will be found close to where he or she was last seen.

Then the researchers add the "island biographic theory," which maintains that locales with more resources — palm trees for tropical birds and electricity for wealthy fugitives — are likelier to draw creatures of interest.

"Island biogeographic theory suggests bin Laden would end up in the biggest and least isolated city of the region," Gillespie says, one among about 26 towns within a 20-mile distance of Tora Bora.
