A few hundred metres from the finish line on Boylston St, a little girl with a prosthetic leg stood with one hand over her heart.
Jane Richard is now 8 years old, the same age her brother Martin was a year ago when the family came to cheer runners through the final metres.
The bomb killed Martin, a smiling, gap-toothed boy who once drew a sign in school that read: "No more hurting people. Peace."
The same explosion tore off Jane's leg and left their mother, Denise, blind in one eye. Their father, Bill, needed two operations to repair ear drums burst by the blast. Only their elder brother, 11-year-old Henry, escaped unhurt. Yesterday, the family returned to the reclaim the scene of the tragedy. "A day doesn't pass when we don't cry over the loss of Martin, but we also laugh when we think about him, which feels like the right way to remember a little boy with a zest for life and a caring heart," a family statement said.
Bostonians were back in Boylston St to reflect on the year since the attacks in which bombs in pressure cookers and carried in backpacks killed four people and wounded more than 260.
