Her father says Krystle, of Medford, Mass., had gone with her best friend to take a picture of the friend's boyfriend crossing the finish line on Monday afternoon.

William Campbell says his daughter, who worked at a restaurant in nearby Arlington, was a "very caring, very loving person, and was daddy's little girl." He says the loss has devastated the family.

He says the friend was seriously injured in the explosion.

An 8-year-old, Martin Richard of Boston, also died. He was at the finish line watching the race with his family.

Three people were killed and more than 170 were wounded after two explosives, reportedly made of pressure cookers and packed with metal and ball bearings and nails, went off on Monday afternoon near the marathon's finish line.

President Barack Obama said it was unclear whether the bombings were carried out by an international organization, domestic group or a "malevolent individual."

Police Commissioner Ed Davis said 176 victims were brought to hospitals around Boston, and 17 were in critical condition. At least eight children were being treated at hospitals.
