The best information appears to have come from al-Sada, who was believed to be his favorite and who traveled with bin Laden since his escape from Afghanistan's eastern Tora Bora mountain range in 2001.
Qadir, a 35-year army veteran who is now a security consultant, was given rare access to transcripts of Pakistani intelligence's interrogation of al-Sada and access to other documents on bin-Laden's movements. He provided the AP with details in a recent interview.
The details of bin Laden's life as a fugitive — which were first published by the Pakistani newspaper Dawn — raise fresh questions over how bin Laden was able to remain undetected for so long in Pakistan after the Sept. 11, 2001 attacks, despite being the subject of a massive international manhunt.
Yet a senior US official, who is familiar with the contents recovered in bin Laden's Abbottabad house, said there was no evidence that Pakistani officials were aware of bin Laden's presence. "There was no smoking gun. We didn't find anything," he said on condition of anonymity because he was not authorized to speak about the contents of the Abbottabad house
According to the interrogation report, bin Laden lived in five safe houses and fathered four children — the two youngest born in a public hospital in Abbotabad. But investigators have only located the houses in Abbottabad and Haripur.
Al-Sada's descriptions of the homes have been vague and the Haripur house was found only after a series of hits and misses.
She knew only that it was located on the edge of Haripur, it was two stories and it had a basement. It apparently was used by bin Laden while he waited for construction crews to finish his new home Abbottabad, a garrison town just 20 miles away.
Investigators scoured the area looking for properties until they found the Haripur house in Naseem Town, a chaotic suburb where relatively affluent houses bump up against sun-baked mud huts that belong to nomadic Afghans.
