Complete Fulfillment:
A massive manhunt was underway Friday morning in Boston and its suburbs, after one suspect in the Boston Marathon bombings died in a confrontation with police and the second was identified as a 19-year-old immigrant from Kyrgyzstan who, a classmate said, attended high school in Cambridge, Mass.
The two suspects are brothers, authorities said, and are believed to have lived in the United States with their family for several years. State Department officials said the family appears to have arrived in the country legally. Boston and its suburbs were in an unprecedented state of lockdown on Friday, with mass transit canceled, schools and business closed and hundreds of thousands residents ordered to stay indoors.
Law enforcement officials said they believed the at-large suspect, Dzhokhar A. Tsarnaev, may be strapped with explosives. They were taking extreme precautions in an effort to avoid further loss of life.
A campus security officer at the Massachusetts Institute of Technology was killed in a confrontation with the suspects Thursday night, and a transit officer was critically wounded.
