BOSOTN (NBC) -- A second victim of Monday's bombings at the Boston Marathon was identified Tuesday as Krystle Campbell, a 29-year-old Massachusetts woman, NBC News has confirmed.

Campbell's father, William Campbell, told NBC News early Tuesday afternoon that his daughter, who was originally from Medford, Mass., died as a result of the explosions Monday afternoon.

In a separate interview with Yahoo News, William Campbell said his daughter was waiting at the finish line for a friend, who was running the race.

"My daughter was the most lovable girl," he said. "She helped everybody, and I'm just so shocked right now. We're just devastated."

Campbell is the second victim of Monday's bombing whose identity has been confirmed. Martin Richard, 8, of Dorchester, Mass., was identified late Monday. The third victim has yet to be named.

In a statement Tuesday, Hordon Health, a fitness and lifestyle training company in Boston, said Campbell was a friend of its owner, Marc Hordon, and urged people to "say a prayer for our loss."

"Krystle was seldom caught not smiling, and not expressing her opinion. She was beautiful, she was loud, and everyone loved her for it ...," the company said.

"Krystle you will be missed not only by those who knew you, loved you, and cherished you the most, but you will be deeply missed by this world as a whole. Your character, your fortitude, your conviction is something that this world desperately needs and now will forever miss."
