Lingzi Lu, a 23-year-old woman, was a food fan, eager for culinary discoveries. In her last blog update the morning before the Boston Marathon blasts, the Chinese student posted a photo of bread chunks and fruit.
Lu often shared photos of her home-prepared meals online: a blueberry-covered waffle one day, spinach sachettini with zucchini on another.
In an interview with ABC News, the father said as he sobbed, "This is an extremely painful time for our family." He said she was their only child.
Lingzi attended the Beijing Institute of Technology, where she graduated last year once got a perfect score on a differential equations exam. She also spent a semester at the University of California, Riverside, in 2010 as part of a student-exchange program.
She was the last of the fatal victims to be identified. The other two people killed in the Boston bombing were 8-year-old Martin Richard and 29-year-old Krystle Campbell.
Campbell was watching the race with her best friend. They were trying to capture a photo of the friend's boyfriend at the finish line when the bomb went off. The friend suffered a severe leg injury, according to Campbell's father.
Campbell's parents, William Campbell Jr. and Patty Campbell, initially thought their daughter had survived. They didn't discover the devastating news until 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 ABC News affiliate station WCVB.
The parents said they are heartbroken over the death of their daughter.
"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," said Patty Campbell.
More than 170 people suffered injuries that included severed limbs, shrapnel wounds, broken bones and head trauma.
