Boston Marathon Bombing Suspects! Manhunt begins.

(CNN) -- A suspect in the Boston Marathon bombings was on the run Friday as thousands of law enforcement authorities cast a wide net that virtually shut down the Massachusetts capital amid warnings the man was possibly armed with explosives.

Authorities say Dzhokar Tsarnaev escaped an overnight shootout in suburban Watertown with police that left his brother Tamerlan Tsarnaev -- the other man wanted in the bombings -- dead.
"Investigators are recovering a significant amount of homemade explosives" from the scene of the shootout, Massachusetts State Police spokesman David Procopio told CNN.

It was not immediately clear what explosives were recovered, but the discovery followed a violent night in which authorities say the brothers allegedly hurled explosives at pursuers after killing an officer, robbing a convenience store and hijacking a car.

Tamerlan Tsarnaev was wearing explosives and a triggering device when he died, a source briefed on the investigation told CNN's Deborah Feyerick on condition of anonymity.
Gov. Deval Patrick called on residents in the city and its suburbs to stay inside "with their doors locked."

I would not want to mess with Boston. They completely shut down most of city, in pursuit of the bombing suspects, and were successful in finding them. They covered the streets with officers, with protective armor, and automatic weapons. Going door to door, searching for any kind of terrorism set up. The police told residents to stay inside closed doors. Even the Boston red sox postponed their game this evening, to show support to the Law enforcement. Bravo Boston! - From the Moon
