Her father, William A. Campbell Jr., told Yahoo News he's in shock that his daughter was killed.

"My daughter was the most lovable girl. She helped everybody, and I'm just so shocked right now. We're just devastated," he said. "She was a wonderful, wonderful girl. Always willing to lend a hand."

Campbell was at the finish line with a friend, Karen Rand, to cheer on her boyfriend, who was running the race. William Campbell said he doesn't know if Rand's boyfriend finished the race before the bombs went off.

Karen Rand survived, but was in surgery for her serious injuries through Monday night. Cheryl Rand Engelhardt, Karen Rand's sister-in-law, wrote on Facebook that Krystle's parents at first believed that Karen was their daughter, and that she had survived the attack, because Karen was carrying Krystle's ID. Krystle's family was finally ushered into Karen's hospital room after one of her leg surgeries by hospital staff, only to discover their daughter's friend instead of Krystle. Krystle was then declared missing, and the family found out on Tuesday she was among the dead.
