Here's your man. Straps on backpack look like one destroyed by bomb. Plus, I agree with above statements.You really don't see the similarity in dress? I don't really see these guys as the culprits unless I put on my tinfoil hat and conclude the gov. staged this attack. There are other interesting people in the photos.]
This guy is a good suspect. He isn't wearing the backpack and I'd conclude it is because wearing it with a pressure cooker would be uncomfortable. He also looks unstable. This is all conjecture anyway.
