Boston PD commissioner Ed Davis told reporters that bombing suspect Dzokhar Tsarnaev is in "serious" condition at a hospital. At least some of his injuries appear to have occured before the firefight that led to his final capture Friday evening, perhaps in Thursday's shootout with cops that resulted in the death of one officer, MIT campus police officer Sean Collier.
Davis described how they caught Tsarnaev:
"There was a call that came into the Watertown police. Three Boston police officers along with state troopers, and FBI agents responded to Franklin street. A man had gone out of his house after being inside the house all day, abiding by our request to stay inside. He walked outside and saw blood on the boat in the backyard. He then opened the tarp on the top of the boat and looked in and saw a man covered with blood. He retreated and called us. We set up a perimeter around that boat and over the course of the next hour or so, we exchanged gunfire with the suspect who was inside the boat. And ultimately, the hostage rescue team or FBI made an entry into the boat and removed the suspect who was still alive in the boat."
