A second victim was named by several news outlets as 29-year-old Krystle Campbell.
Her father, William A. Campbell Jr, who was at the finish line as the bombs went off, told Yahoo News: “My daughter was the most lovable girl.
“She helped everybody, and I’m just so shocked right now. We’re just devastated. She was a wonderful, wonderful girl. Always willing to lend a hand.”
Ms Campbell, from Medford, Massachusetts, is listed on her LinkedIn profile as a restaurant manager.
Summer Shack, the restaurant where she worked which has a branch only minutes from where the bombs exploded, tweeted: “The Summer Shack family is devastated by the loss of our beloved Krystle Campbell. “Please keep her & her– family in your thoughts & prayers.”
Irish roots
Hordon HEALTH,
a lifestyle management company, posted on its Facebook page that they had "lost a member of its extended family yesterday" as Ms Campbell was a friend of the company's founder, Marc Hordon.
The post read: “She was beautiful, she was loud, and everyone loved her for it. Along with the million dollar smile came head to toe freckles and gorgeous bright red hair, connecting her Irish roots and kid-like manor; it was easy to feel 10 years younger around her, no matter who you were.
She had tremendous passion and energy, and Krystle attacked life with vigour and excitement.
“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.”
Mayor Michael McGlynn said he had confirmed the death with Campbell’s father, William Campbell.
“Mr Campbell said that she certainly was a dream daughter, the daughter that every father dreams to have and friends of hers said that she was eager about life.
“She had a great sense of humour and freckles and red hair that brought her right to her Irish roots. She was someone who worked hard at everything she did,” McGlynn said.
Another friend said she may have been a little loud at times but it was a loudness you loved.
The identity of the third person killed has not been released. In addition to the three people killed, more than 170 others were hurt in the two blasts on Monday.
