Boston victim Krystle Campbell had 'a heart of gold'
Patty Campbell, the mother of one of three people to lose their lives in the Boston Marathon bombings, has spoken of her heartbreak.
She described her daughter as a wonderful person with a heart of gold.
Krystle Marie Campbell, 29, was killed in the attacks - along with an eight-year-old boy and a postgraduate student from China.
More than 170 people were injured when two bombs exploded near the finish line of Monday's race.
Investigators say the devices that targeted the Boston Marathon on Monday may have been packed in pressure cookers.
