Hundreds Gather for Boston Vigils

Two vigils honoring victims of Monday's bombings in Boston attracted hundreds of mourners Tuesday night. Holding candles and flowers, several hundred people gathered in the Boston Commons, where an a cappella chorus sing the National Anthem and God Bless America. In Dorchester, miles from the city, hundreds paid tribute to 8-year-old Martin Richard, who was killed in the attack. A priest called him a "beautiful and gentle soul," and neighbors remembered the cheerful young boy. President Obama is scheduled to arrive in Boston on Thursday to attend a commemorative event.
