1 marathon bomber suspect confirmed in custody, so the other one on the loose (white male, curly hair) is obviously the other one.

Don't know still if they are the ones who shot the MIT officer though.

The police have confirmed that they are looking for the guys from Monday's Boston Marathon Bombing. Guy with white hat still at large.

Possibly has an ied device

"the party outstanding would be the one with the white hat identified in the photos" -scanner

Seeems like these are the bombers for sure. speculating that they were trying to privately hide a bomb at mit, but got caught, and this shit happened.
