1:15 p.m.
The families of victims of the 2013 Boston Marathon bombings are doing community service projects in the city on the third anniversary of the attacks.
Members of 8-year-old victim Martin Richard helped clean a busy commercial street and square in their Dorchester neighborhood.
Family friend Sheila McCarthy says dozens of volunteers have been out since the morning hours picking up trash and planting flowers as a way to help and support the family, which picked the service project.
It was among a number of community service activities happening throughout the city, including blood drives, food and clothing collections, and other projects.
The family of Lingzi Lu, a 23-year-old Boston University graduate student killed in the attack, was expected to making a donation to the Police Department's Athletic League in City Hall.

8:45 a.m.
Massachusetts Gov. Charlie Baker and Boston Mayor Marty Walsh joined dozens of others for a simple and somber wreath-laying ceremony to remember the victims of the 2013 Boston Marathon bombing.
Baker, joined by the father of victim Krystle Campbell, bowed his head in silence on Friday morning after laying a wreath at the site of one explosion. Walsh, with the family of victim Martin Richard, placed a wreath at the second blast site.
At 2:49 p.m., a citywide moment of silence will mark the time when the first of two pressure cooker bombs detonated near the race's end, killing three people and injuring over 260 others.
Throughout the day, residents will be taking part in blood drives, food and clothing collections and other community service projects to celebrate Boston's generosity and resilience.
