Chaos: Suspect Surrender Caught on Tape Following MIT Cop Killing, Gunfire and Explosions in Watertown

Update -- At the original time of this posting (2:20am on 4/19/13) it wasn't clear if this was related to the Boston Marathon Attack or whether this was one of the suspects involved. News stations reported a suspect was in custody at the time. Authorities have since released this individual, but it illustrates the chaos from last night.

This is very up-close news footage of a suspect on the ground and surrendering during the chaos in Watertown in the early morning hours.
