A Boston University graduate student was identified today as the third person to die from the terrorist bombing at the Boston marathon. The two other fatalities from the attack were identified earlier today as a boy and a young woman. 
 
 "The student was one of three friends who watched the race near the finish line," Boston University posted on its website. "Another of the three students, also a BU grad student, was injured and is in stable condition at Boston Medical Center." 
 
 The university did not release the student's name, pending permission from the family. The injured BU student underwent surgery and is recovering. The third BU student was unharmed.

 Earlier today Krystle Campbell, 29, joined Martin Richard, 8, as the two other fatalities identified from the Monday attack. 
 
 Campbell's parents William Campbell Jr. and Patty Campbell at first thought their daughter's friend had been killed, but later learned that it was their daughter who was the victim, according to ABC News' Boston affiliate WCVB. 
 
 The parents discovered their daughter was the one who had died when they were finally allowed to see the patient who had survived. 
 
 "I said, 'That's not my daughter. That's Karen! Where's my daughter?'" Patty Campbell told WCVB. 
 
 "My daughter was the most lovable girl. She helped everybody and I'm just so shocked right now. We're just devastated," William Campbell Jr. told Yahoo News. "She was a wonderful, wonderful girl. Always willing to lend a hand." 
 
 The parents are struggling to comprehend their loss. 
 
 "She didn't deserve this," Patty Campbell told WCVB. "She was a beautiful young being. She loved pets. She loved people." 
 
 Campbell told WCVB that her daughter worked 16-hour days in the food service industry. 
 
 "We can't believe it," the devastated mother said. "This is just a waste." 
 
 She said her daughter was at the race to cheer on a friend. 
 
 A sobbing Patty Campbell later made a brief statement from the family's porch: "We are heartbroken at the death of our daughter Krystle Marie. She was a wonderful person. Everybody loved her. She had a heart of gold and was always smiling. She worked hard in everything she did. You couldn't ask for a better daughter. This doesn't make any sense. " 
 
 The deaths of Campbell and Richard, who was from Dorchester, Mass., has left the country in mourning. The boy's mother and sister were also seriously wounded in the bombings. 
 
 Martin was remembered as a typical 8-year-old who loved to ride his bike and play baseball, according to a neighbor. 
 
 A single candle was placed in front of his home overnight in Dorchester, Mass. 
 
 "There are no words to describe how they are feeling ... we are feeling," neighbor Jane Sherman told WCVB, adding that the family is close-knit. 
 
 At least 145 people, including 10 children, were injured in the attack, according to the latest ABC News count. At least 17 people are in critical condition. 
 
 Dr. Vivek Shah was among those who provided on-site assistance He had just crossed the 26.2-mile finish line at the marathon Monday when he was forced to put his medical skills to work. 
 
 "I've never obviously been in combat, but people I've trained with have been and this is as close as I can imagine it would be," Shah told ABC News Radio late Monday night. "Just, basically piles of victims. Everything I saw was a traumatic amputation, basically." 
 
 Shah, an orthopedic surgeon at New England Baptist Hospital in Roxbury Crossing, Mass., said he saw injuries along the sidewalks on Boylston Street for which no amount of training could prepare him. 
 
 "In all my medical training, I have not seen things that I saw [Monday]. Everything was traumatic," Shah said. 
 
 Spectator Aaron Hern, 11, of Martinez, Calif., was another young victim injured when flying shrapnel dug into his thigh as he was waiting for his mother to cross the finish line. Hern is being treated at Boston Children's Hospital. 
 
 "He was waiting for his mom to go through the finish line to take pictures of her and shortly before she got there, the bomb went off," family friend Janene Sides told ABC News affiliate KGO-TV. 
 
 On Facebook, Aaron's mother, Katherine, said her son was in stable condition in the ICU late Monday night. Hern said Aaron would have additional surgeries and is expected to be hospitalized for seven to 10 days.

 Hern's injuries are similar to what doctors at two Massachusetts hospitals described Monday night, hours after the explosions. Some of the most critical patients sustained lower extremity injuries from debris. 
 
 Dr. George Velmahos, chief of trauma at Massachusetts General Hospital, told a news conference today that patients were hit by what appeared to be shrapnel packed into the bombs, what he described as "Nails or sharp objects." 
 
 "I can't say for certainty, but that's what they look like. [They're] numerous… 10, 20, 30, 40 in their bodies, maybe more," Velmahos said. 
 
 Dr. Ron Walls, chair of emergency medicine at Brigham and Women's Hospital, said, "The most common serious injuries are combined lower extremity injuries." 
 
 Doctors have said they carried out several amputations.

 Martin Richard was killed in the bombing. His mother and sister were also injured in the blasts. 
 
 Hundreds attended a vigil Tuesday night for Martin at Garvey Park in Dorchester. 
 
 His mother Denise reportedly sustained a head injury and his 7-year-old sister has a serious leg injury, according to the Dorchester Reporter. Both are in area hospitals. 
 
 Martin’s father Bill Richard released a statement Tuesday afternoon saying: 
 
 My dear son Martin has died from injuries sustained in the attack on Boston. My wife and daughter are both recovering from serious injuries. We thank our family and friends, those we know and those we have never met, for their thoughts and prayers. I ask that you continue to pray for my family as we remember Martin. We also ask for your patience and for privacy as we work to simultaneously grieve and recover. Thank you. 
 
 Martin was reportedly at the race to watch his father, a community leader in Dorchester, according to the paper. 
 
 WBZ-TV’s Michael Rosenfield was outside the Richard home in the Ashmont section where some people had stopped Tuesday morning to drop off flowers and candles. 
 
 Neighbor Dan Aguliar said he can’t believe it happened in Boston. 
 
 “It’s still unreal, it’s amazing you see this happen in other places and as cliche as it is you always think it’s never going to happen in your backyard,” Aguliar said. “To know that little boy will never come home again will keep me up at night and will probably keep me up some more nights.” 
 
 Aguliar told WBZ-TV the family has lived in the home for around 14 years. 
 
 The word “peace” was written on the sidewalk, outside the home. 
 
 Family members have declined to comment.

 "We're going to make sure the city pulls together," Mayor Thomas Menino says.

 Second victim was Krystle Campbell, 29, a restaurant manager from Medford, Mass. 
 
 BOSTON — This rattled city was grappling Tuesday with the painful process of identifying its dead, a strong police presence on its streets, and a firm resolve to heal and move forward. 
 
 One day after two bombs rocked the finish line of the Boston Marathon and the nerves of residents and tourists here, police promised "significantly enhanced" security at bus and train stations and airports. And the mayor promised that the city won't be intimidated by terror. 
 
 "We're going to make sure the city pulls together," Mayor Thomas Menino said Tuesday. "Boston's a strong city. ... Boston will overcome." 
 
 Tuesday evening, the third victim was identified as a Boston University graduate student from China who was watching the race with two friends near the finish line. 
 
 The Chinese Consulate in New York confirmed the student's death, the Associated Press reported Tuesday night. 
 
 The university did not release the student's name or gender, pending family approval. But the official Chinese news agency Xinhua reported that relatives have requested that the student not be identified. 
 
 One friend was injured and listed in stable condition at a Boston hospital. The other friend was not hurt. 
 
 Earlier Tuesday, restaurant manager Krystle Campbell, 29, was the second fatality identified. Martin Richard, 8, was identified Monday. 
 
 Campbell's father said the Medford, Mass., resident had gone to the finish line Monday afternoon to photograph a friend completing the run. William Campbell said his daughter, who worked at a restaurant, was "very caring, very loving person, and was daddy's little girl." 
 
 Tuesday afternoon, Campbell's grief-stricken mother, Patricia, spoke briefly from the front steps of their home in the Boston suburb of Arlington. 
 
 "Everybody that knew her loved her," she said, weeping, supported by a young man. "You couldn't ask for a better daughter.... I can't believe this has happened. It doesn't make any sense." 
 
 Across the city, the Salvation Army mobilized four mobile kitchens and more than 30 people to provide food, drinks, and emotional and spiritual care. The First Corps of Cadets Armory in downtown Boston, unofficially known as "The Castle," became a staging area for runners looking for their gear bags, trying to find lost phones and passports or trying to make travel arrangements. 
 
 Valerie Kelly, 28, a schoolteacher who lives in Boston, stopped in at the armory. She said the course was closed before she could finish the race. Fortunately, none of her students at the finish line to greet her were injured. 
 
 "It was really hard to register. You work so hard for this moment of glory, and you're going through so many emotions," she said. "Then you go from that to you can't finish and then you immediately go from that to 'Oh my God, are my family and students OK?' " 
 
 Still, there were small signs of a return to normalcy Tuesday. The sealed crime scene centered at the intersection of Boylston and Exeter streets shrank from 15 blocks to 12. Planes, trains and automobiles were running at or near normal operating schedules. Airlines at Boston's Logan International Airport were even waiving change fees for customers scheduled to fly there during the next few days. 
 
 Some runners, their gait a little off from their brutal run a day before, took recovery runs Tuesday to work out the kinks. Others, wearing the blue and yellow running jackets issued to runners, walked the streets of Back Bay, about a quarter mile from the finish line. They made their way past a chorus line of Boston police, state police and ATF agents and barricades. 
 
 A handful of people wearing business clothes moved along sidewalks too, although most businesses remained closed and the mood was subdued. 
 
 A pall also hung over the wood-frame Dorchester home of victim Martin Richard. His mother and sister were seriously injured. On Tuesday, neighbors or even strangers walked or drove up to leave flowers or balloons on the front steps. Police set up yellow tape to prevent the press from getting too close, and a Boston police sergeant took gifts to the home for the visitors. 
 
 One group of people — two adults and two children — who left balloons held onto one another as they walked away. 
 
 The blasts occurred just before 3 p.m., just hours after Ethiopia's Lelisa Desisa won the 26.2-mile race Monday. Bloodied spectators were carried to a medical tent intended for runners. 
 
 Organizers stopped the race and locked down the marathon headquarters. The Federal Aviation Administration announced a temporary flight restriction over Boston. 
 
 The tragedy brought words of encouragement and solidarity from across the nation — and around the world. 
 
 President Obama praised first responders and others who helped the injured. "If you want to know who we are, what America is, how we respond to evil, that's it: selflessly, compassionately, unafraid," he said. 
 
 The president will travel to the city Thursday for an interfaith service. 
 
 Pope Francis sent word Tuesday to Cardinal Sean O'Malley, archbishop of Boston, that he was "deeply grieved" by the bombings. The pope said he "invokes God's peace upon the dead, his consolation upon the suffering, and his strength upon all those engaged in the continuing work of relief and response." 
 
 Francis also prayed that all would be "united in a resolve not to be overcome by evil, but to combat evil with good, working together to build an ever more just, free and secure society for generations yet to come." 
 
 In Boston, District Attorney Daniel Conley couldn't agree more. 
 
 "Moments like this, and our response to them, define who we are," Conley said "In the past 24 hours, the city of Boston has shown strength, compassion and determination to see justice done."

– Another fatality in the Boston bombings has been identified: The family of 29-year-old Krystle Campbell says she was killed as she and a friend were cheering on another friend who was racing, reports WCVB. "This is just a waste," says her mother. “Everyone that knew her loved her. She was always smiling. You couldn’t ask for a better daughter. She was the best.” Campbell was a restaurant manager, reports the Boston Herald, which notes an especially wrenching detail: Her father was initially told she was alive, but when he got to the ICU, he realized it was his daughter's friend who had survived.

The first was 8-year-old Martin Richard, and his father, Bill, released a statement today thanking supporters and asking for privacy, reports WBZ. "My dear son Martin has died from injuries sustained in the attack on Boston. My wife and daughter are both recovering from serious injuries. We thank our family and friends, those we know and those we have never met, for their thoughts and prayers. I ask that you continue to pray for my family as we remember Martin.
