Boston Is Locked Down With City Frozen From Tufts to Trains

Boston area residents awoke to a city virtually paralyzed after a night of mayhem that left at least two dead and police searching house to house for a suspect believed to be responsible for the Boston Marathon bombings.

As dawn broke over the city, police had already ordered a shutdown of all public transit in the region while officers armed with assault rifles conducted a search in Watertown, 10 miles west of downtown Boston, looking for Dzhokar Tsarnaev, a 19-year-old foreign national who had escaped during a confrontation with police.
