A profound heartache burns deeply for the rescuers, survivors and victims who will observe this month the second anniversary of the Boston Marathon bombing spree. Just two years ago, a massive search for two suspects alleged to have detonated twin blasts at the race’s finish line shut down the entire metropolitan area for four days.

Twenty-three months later, the wheels of justice are churning in the U.S. district court in Boston where the accused faces a 30-count federal indictment. In 15 days of testimony calling upon 92 witnesses, the prosecution detailed how the defendant and his late brother detonated pressure-cooker bombs, which took the lives of three people, including an 8-year-old boy, and injured 264 people, of whom 14 required amputations from the violent explosions. The defense worked to portray the deceased brother as the mastermind of the crime and humanize the defendant for the jury.
