This is funny... On another note, does anyone know how the LE got the names of the suspects when they were looking for them? Did they discover their names, or did some citizen call them in. I still have not heard anyone answer this question. Maybe I missed it.
I was up all Thursday night with the live thread of the chase.
At the time, I deduced that the authorities got their names by virtue of Suspect #1s demise. Shortly after he was taken to the hospital, the names were announced.
Rebuilding the sequence in retrospect:
The owner of car-jacked Mercedes escaped and called the police, telling them the Marathon bombers had stolen his car.
The Boston police focussed on the car, found it...and the chase and firefight ensued.
Suspect #1 got himself shot, then run over by his brother. He ends up in the hospital...with his identification on him.
Suspect #1 is thus identified as Tamarlan Tsarnaev and, from there, it's a quick trip to identifying Suspect #2 as his younger brother Dzhokhar (which could be easily confirmed by the surveillance photos).
