In seconds, a scene of celebration transformed into one of carnage, as two bombs
exploded near the finish line of the Boston Marathon in April. Three people were
killed and more than 260 injured, including at least 16 who lost limbs. Authorities
soon identified two suspects — 26-year-old Tamerlan Tsarnaev, who died in a
shootout with police, and his brother, Dzhokhar, 20, who faces multiple charges,
including 17 that carry a possible death penalty. Though jolted by the bombings
and a subsequent lockdown, the city rallied under the slogan "Boston Strong."
