Seems to be him.
But he is probably on the plane on the way back to Saudi Arabia with the other two as arranged late nite session in the white house with Obama and one of the Saudi Princes he bows to.
The guy is the calmest person in that picture as he is the only one that knows there will not be another blast.
If you examine the 2nd photo at the link which was posted a few posts ago, which I will post here
http://imgur.com/a/fEZhX. The pic shows the suspect walking away. The odd thing is that he his holding the backpack on right shoulder and his left shoulder is slouching downward to the left. If the backpack was weighted, the right shoulder would be slouching to the right. try is yourself and you would see. This shows a consistency to the facebook picture of the guy with the bad left arm and the drooping left shoulder. That is the same guy. if you include the pic next to the brick building, the left elbow looks odd as well. It is out of proportion. The guy standing next to him in the facebook photo with his arms around him looks like the other suspect with the black cap. Same color skin and stocky build. This is pretty obvious to me. What are they hiding?
