Police said an 8-year-old boy who was waiting for his father to finish the race was among the people killed when two bombs exploded near the finish line of the Boston Marathon. The boy's mother and sister were also reportedly injured.

CNN and other news organizations identified the boy as Martin Richard.

Boston TV station WHDH said Martin was a third-grader from Dorchester, Mass.

His mother was hospitalized with brain injury from the blast, while his 6-year-old sister lost a leg, according to the station.

Martin's parents were identified as William and Denise Richard.

“They are beloved by this community," City Councilor  Ayanna Pressley told the Boston Globe at a gathering at a local restaurant. "They contribute in many ways. That’s why you see this outpouring. It’s surreal, it’s tragic, it’s incomprehensible. Everyone here tonight is trying to comfort one another and be prayerful.”
