BOSTON MARATHON BOMBING-ARTIFACTS

BOSTON — After the twin bombings at the Boston Marathon, mourners began leaving thousands of items at a makeshift memorial near the finish line to honor the victims of the attacks. Some left teddy bears, signs and marathon bibs while others draped running sneakers to commemorate the three people killed and more than 260 injured during the April 15 attacks. To mark the anniversary of the bombings, the material will be curated into an exhibit hosted by the Boston Public Library. By Paige Sutherland. 620 words, photos. Sent March 31.

BOSTON MARATHON BOMBING-BAUMAN

CARLISLE, Mass. — Jeff Bauman lost both his legs in the Boston Marathon bombings, injuries documented in an arresting Associated Press photograph that showed him being rushed from the scene in a wheelchair by three rescuers. He then became a hero when he played a key role in identifying the men suspected of placing the two bombs. Bauman spoke with the AP about his recovery on the eve of the publication of his book about the past year. By Michelle R. Smith. 930 words, AP Photos MACK701-709. Sent April 5.

BOSTON MARATHON BOMBING-HEALING THE WOUNDS

BOSTON — Every time Roseann Sdoia comes home, she must climb 18 steps — six stairs into the building, another 12 to her apartment. It is an old building in Boston's North End, with doors that are big and heavy, not an easy place for an amputee to live. When she left the hospital, a month after the Boston marathon bombing, she had to choose whether to stay. "Early on when all this happened, so many people were telling me to move out of the city and move out of my apartment because of the stairs and I don't have an elevator and parking is not very convenient," she recalls. "But I have been able to get past all of that."

In that, she mirrors Boston itself. In the course of a year, limbs have been replaced, psyches soothed, the wounds sustained in a moment at the marathon's finish line have at least begun to heal. At the same time, a city shaken by an unthinkable act of terrorism has returned to its usual rhythms — sadder, but some say stronger, as well.

BOSTON BOMBING-HEROES-PHOTO ESSAY

An EMT. A volunteer. A spectator in a cowboy hat. Moments after bombs exploded at the Boston Marathon, these three helped rescue a man whose legs were blown off, a scene captured in an Associated Press photo. That man, Jeff Bauman, was lauded as a hero himself when he gave authorities a description that helped them track down two suspects. A year later, the AP revisited the lives of the four people in the image. By Charles Krupa and Michelle R. Smith. 480 words, 10 photos. Sent April 13.

BOSTON MARATHON BOMBING-THE INVESTIGATION

BOSTON — A year after two bombs ripped through crowds gathered at the Boston Marathon finish line, killing three people and injuring more than 260, one suspect is awaiting trial and the other is dead. Although prosecutors believe they have strong evidence of Dzhokhar Tsarnaev's guilt, there are still many unanswered questions about the attacks and the men at the center of the investigation.

BOSTON MARATHON BOMBING-TRIPLE SLAYING

WALTHAM, Mass. — It was a grisly slaying in a suburb that sometimes goes years without one murder, let alone three. Now questions linger not only about who killed three young men in 2011, but also whether the Boston Marathon bombings could have been prevented if their case had been solved. Police initially believed the killings were drug-related, either a drug robbery gone bad or a drug hit. It wasn't until two bombs exploded at the marathon that investigators began focusing on a new suspect: Tamerlan Tsarnaev, one of two brothers who authorities say orchestrated and carried out the bombings.

BOSTON MARATHON-UNFINISHED BUSINESS

LITTLE ROCK, Ark. — Amputee runner Jeff Glasbrenner was three-tenths of a mile from the finish at the Boston Marathon last spring when the twin pressure cooker bombs exploded. He's among the 5,633 runners who didn't finish last year but were given the chance return and cross the finish line a year later. This time, Glasbrenner is bringing some company. He trained two fellow right-leg amputees who had never even imagined running a marathon before. For him, it's all about the finish line. For them, it's about the start.

BOSTON MARATHON-POLITICAL IMPACT

BOSTON — In the days after the bombing, the nation's political leaders pledged resources and support for a city grappling with the first terror attack on American soil since Sept. 11, 2001. Nearly a year after homemade bombs ripped through the Boston Marathon, state and federal officials have enacted virtually no policy changes in response to the attack, a dramatic departure from previous acts of terrorism that prompted waves of government action. .

BOSTON MARATHON-FIELD

BOSTON — More than 5,000 runners were still on the Boston Marathon course when the bombs went off on Boylston Street. Race organizers were eager to invite them back — to give them a chance to finish what they started — and conscious of the message that would send. After also making room for first-responders and victims, the Boston Athletic Association is trying to find space for one of the largest fields in the race's 118-year history.

BOSTON MARATHON TOURISM

BOSTON — With an additional 9,000 runners for this year's Boston Marathon, hotel rooms in Boston were already harder than usual to come by. Add the people who aren't running but just want to be part of the experience, and the company that handles bookings for the Boston Athletic Association has had to find space for people far outside the city. "The appearance is people seem to be embracing the whole experience this year differently than in past years," says Thomas Gilligan of Marathon Tours and Travel. "There's an emotional side to the event that didn't exist in previous years." 600 words, photos. Moving by 2 p.m. Friday, April 18.

BOSTON MARATHON

BOSTON MARATHON-PROFOUNDLY AFFECTED

BOSTON — Nursing student Sarah Gesse was working as a volunteer on the medical sweep team at the finish line of the Boston Marathon when the bombs exploded on Boylston Street. This year, she will run in the race, "one more runner proving how strong Boston really is." Gesse obtained her bib number through a special application process added to include those "personally and profoundly affected" by last year's attacks, and she will run to raise money for fellow UMass student Krystle Campbell, who died in the explosions.
