Boston Seeks Answers in Deadly Blasts

BOSTON — The day after two powerful bombs exploded near the finish line of the Boston Marathon, a mile-square area of downtown Boston remained cordoned off as a crime scene, and officials still had no one in custody. However, investigators searched a house in a nearby suburb late Monday night.
Hundreds of runners who had expected to leave Boston on Tuesday morning with a sense of triumph after a night of celebration left instead with heavy hearts after at least three people were killed and more than 140 were injured, some of them having lost limbs and suffered grievous wounds.
Among the dead was an 8-year-old boy, identified by The Boston Globe as Martin Richard of Dorchester. Friends and family gathered Monday night at a restaurant to mourn him; he had been watching the marathon with his family, and his mother and a sister were badly injured. The names of the other victims have not been made public.
