Margaret Warner reports. It was the news most Americans had waited nearly a decade to hear it after a firefight. They killed Osama bin Laden and took custody of his body. But for many of the people who helped find Osama bin Laden their work started nearly two decades earlier. Long before the most wanted man on earth had earned his infamy. Their story of

Next new details of the secret life of Osama bin Laden between 9/11. And today he was killed by US Navy SEALs in Pakistan nearly ten years later. Margaret Warner has the story. Much of the new information comes from Pakistani interrogations of bin Laden's youngest wife. A thirty year old Yemeni who sustained a gunshot wound to her leg the -- bin Laden was killed. Interrogation report first disclosed by the Pakistani newspaper dawn. Shows bin Laden and his three wives were living in Pakistani cities and towns. For nearly all the time the Americans were hunting him after the November 2001 invasion of Afghanistan. I'm not -- went out -- by Tate told interrogators that from 2002 to 2010. Bin Laden moved among at least five houses and father for children. In the northwest city of a shower near the Afghan border. In the swat district eighty miles from the capital Islamabad. The small town of Harry pour in the same region and finally from 2005. On in a bottom by just thirty miles from Islamabad. Hot tea and the two older Saudi widows of bin Laden are now under house arrest in the capital. And for more on all of this we turn to Jacqueline Walsh of the New York Times in Islamabad has been reporting this story. And Washington Post columnist David Ignatius who's written widely on Pakistan and has had access to some of the documents found in bin Laden's last house. Welcome to you bought that one beginning with you. The picture that emerges here. It's quite the opposite of what many Americans thought for a long time when it was that bin Laden was some kind of punted figure on Iran living in case. As flesh it out for us the picture that we get from the house. I absolutely do working assumption for -- certainly most of the public interpretation of -- bin Laden's whereabouts from most of the past decade. Has been that he was in Pakistan's tribal belt along the border with Afghanistan. And this testimony from his youngest wife Nat suggests that about walking the case. Up in Latin and fox spent most of his time in Chicago booked in -- province which is next to talk about but which is very much part of the fact that there is a pox on if you like. Bin Laden's wife says that she met him in the shower which is the main city in that region in around mid 2002. That they moved to north into the mountains into the Hindu Kush. To the swap -- -- they spent some time there. With the relative into houses with the relatives of a close associate of his. Then they moved to another house in a place called Harry -- as you say where bin Laden's youngest wife gave birth to two children in a local government hospital. Apparently staying in the hospital for a short period of 23 hours on each occasion. And then finally they moved to the house in public about the mid 2005. Where they stayed for six years until the American Navy SEALs broke through the door that last may it. Killed bin Laden and wounded his youngest wife during the -- And what. It tell us about she's quite specific about who help them in all these moves and found the house a sport that. Tell us briefly about that. Well on the one hand there is a very little information I've talked about who exactly was helping the bin Laden family there's number references in these documents. Particularly in the -- any part of their journey through Pakistan to. What are referred to us Pakistani families but giving. Very little other details about who was helping and that's very intriguing. And but secondly it seems that in the latter part of their stay in the second part of the last decade -- -- it in impacts -- rather. The bin Laden family was sheltered by a pair of Pashtun Brothers these are referred to in the document says Ibrahim I'm abroad. Ibrahim as believed to be imam who has known to American intelligence as the courier. Because you both the person who was delivering. Messages from bin Laden to the outside -- most of this time. At the corner and his brother and their families lived with bin Laden's wives over most of that period and it seems protected them as well. So David Ignatius what does this. In Toto add to our understanding of bin Laden's really the last decade of a slight -- -- Well it it flushes out a picture of this man. In in hiding but but. Really so far from the from a fight. We have imagined him as you said earlier in caves. With them later predator attacks over overhead. I think the question that's raised by these documents is who who knew about bin Laden's movements. It it just strains any credulity that. That he could have lived in five different houses in Pakistan. That is --

It's been an emotional week since the dramatic US operation that killed Osama bin Laden in Pakistan. On Thursday President Obama laid a wreath at ground zero. You met with loved ones and some of those killed on 9/11 and told them he hoped bin Laden's death brought them a small measure of comfort. The president repeatedly cited the 9/11 attacks when he announced the operation on Sunday.
