BOSTON (AP) -- The twin bombs at the Boston Marathon killed three people and wounded more than 170 on Monday. Here are the stories of those killed and some of the injured.
LU LINGZI: A LONG WAY FROM HOME
She was a food fan, eager for culinary discoveries. In her last blog update the morning before the Boston Marathon blasts, the Chinese graduate student identified as the attack's third victim posted a photo of bread chunks and fruit.
"My wonderful breakfast," Boston University statistics student Lu Lingzi wrote.
In her early 20s, she often shared photos of her home-prepared meals online -- a blueberry-covered waffle one day, spinach sachettini with zucchini on another. In September, she showed off her first two-dish meal -- stir-fried broccoli and scrambled eggs with tomatoes, often cooked by Chinese students learning how to live on their own abroad.
Tasso Kaper, the chair of BU's mathematics department, says Lu loved flowers and the springtime. She had only one course left in order to graduate.
She was standing with two friends when the bombs went off. One was seriously injured.
THE RICHARDS: A FAMILY INJURED, IN MOURNING
Neighbors and friends remembered 8-year-old bombing victim Martin Richard as a vivacious boy who loved to run, climb and play sports like soccer, basketball and baseball.
The boy's father, Bill Richard, released a statement thanking family, friends and strangers for their support following his son's death Monday. Richard's wife, Denise, and the couple's 6-year-old daughter, Jane, also suffered significant injuries in the blasts.
The family was watching Monday's race and had gone to get ice cream before returning to the area near the finish line before the blasts.
Denise Richard works as a librarian at the Neighborhood House Charter School, where Martin was a third-grader and Jane attends first grade. Counselors were being made available to staff and students.
"I just can't get a handle on it," family friend Jack Cunningham said of the boy's death. "In an instant, life changes."
KRYSTLE CAMPBELL: CHEERING ON FRIENDS
Krystle Campbell was a 29-year-old restaurant manager from Medford. Her father, 56-year-old William Campbell, described her as "just a very caring, very loving person, and was daddy's little girl."
Campbell had gone to the race with her best friend Karen, whose boyfriend was running in the race, her father said.
"They wanted to take a photograph of him crossing the finish line, but the explosion went off and they were right there," he said. "It's pretty devastating."
The friend suffered a severe leg injury.
Krystle's grandmother told multiple media outlets that the family was initially told Campbell was alive because of a name mix-up. When her father arrived at Massachusetts General Hospital, however, he learned that his daughter had died.
Krystle's grandmother, Lillian Campbell, said somewhere on the way to the hospital, their names got mixed up.
Lillian Campbell said her son was "devastated" when he found out the truth and almost passed out.
JEFF BAUMAN JR.: LOST BOTH LEGS
Jeff Bauman Jr., a man pictured in an Associated Press photo from immediately after the blast, lost both his legs as cheered his girlfriend on in the race. He survived the trauma after people rushed him away from the explosion site in a wheelchair.
Rescuers took the 27-year-old victim to Boston Medical Center, but doctors had to amputate his legs because of extensive vascular and bone damage, a Facebook post from his father said Tuesday.
"Unfortunately my son was just in the wrong place at the wrong time," the elder Jeff Bauman wrote.
The son also had to have more surgery later because of fluid in his abdomen. His condition improved later.
"I just can't explain what's wrong with people today to do this to people," the father wrote. "I'm really starting to lose faith in our country."
BRITTANY LORING: AN AMBITIOUS STUDENT
Brittany Loring was spending Monday, her 29th birthday, cheering on her friend in the Boston Marathon. A day later, she lay in critical condition with injuries to her head, leg and fingers.
"We've had so many calls. Everybody's just upset over it," grandmother Philomena Loring told the Lowell Sun. "I put her on the prayer line at my church."
Loring is simultaneously pursuing degrees in law and business administration at Boston College. She's also a runner, finishing 80th in the Boston College MBA 5K on April 6.
HEATHER ABBOTT: BEST FRIEND TURNED, FOUND HER GONE
Heather Abbott, of Newport, R.I., was entering a bar with friends as the bomb went off. Her best friend, Jason Geremia, told WJAR-TV that everyone ran out the back. Once he got there, he realized Abbott wasn't with him. He turned to go back when he saw a bouncer carrying her down the stairs.
"I said, `Give her to me. Give her to me.' And he was like, `Do you know her?' I said, `Yes, yes. That's my best friend.' I said, `Give her to me.' He said, `No, no, no. Look at her leg.' It was very tough to see that."
leg was severely injured. Another friend took off his belt, and they used it as a tourniquet.
Geremia spent much of Monday and Tuesday at the hospital, along with Abbott's parents, who are from Lincoln, R.I.
"It's very, very hard to see her," Geremia said.
