Martin Richard's family says it trusts that the justice system will now "do its job" after the arrest of 19-year-old suspect Dzhokhar Tsarnaev Friday night in the Boston suburb of Watertown. His brother and fellow suspect died in a shootout with police.
Martin was killed in Monday's blast along with two other. His mother and sister were among some 180 others wounded.
The family says it continues to "pray for healing and for comfort" for the rest of the victims on their road to recovery.
