The red stripe in the middle of the building in the back of the compound was where Osama Bin Laden stayed and where he was killed. He lived on the 2nd and 3rd floor. His windows were opaque. The US came in from the ground level and cleared their way to the 2nd floor. Osama Bin Laden was asked to surrender and when met with resistance he was fired upon and killed. He was buried at sea and DNA provided the proof that it was indeed Osama Bin Laden.
