The eight-year-old boy killed in the sudden blasts at the Boston Marathon was Martin Richard of Dorchester, Mass.
Richard was at the race to watch his father cross the finish line, NBC affiliate WHDH reported. The boy's mother and father were identified as William and Denise Richard by the Boston Globe. The boy's mother and his six-year-old sister were reported to have been seriously injured in the explosion. A third child has been reported uninjured.
Friends of the family gathered at Tavolo Restaurant on Monday night in Dorchester, where William Richard is a community leader.
