Krystle Campbell's mother says her daughter "had a heart of gold." The 29 year old restaurant manager died in the Boston Marathon bombing on Monday. In a tragic case of mistaken identity, her family was first told by doctors that she had survived the attack. But the patient they were treating was actually Campbell's friend who was at the race with her that day. CNN's Jason Carroll reports on how she will be remembered by friends and family.
Boston Medical Center's Dr. Natalie Stavas, a pediatric physician, was at the end of the Boston Marathon when she heard the explosions. She says instincts and adrenaline kicked in as she raced toward the devastating scene to aid the wounded. Stavas tells Anderson Cooper she performed CPR on one woman, then cared for another woman who had a sharp object impaled in her groin, and she helped a young man whose foot was severely mangled from the bombings.
Anderson Cooper and John King report on the significance of the photos showing debris from the pressure cooker and fabric from the bag used in the Boston Marathon bombings. Investigators will examine the evidence for fingerprints or DNA or use the serial number to try to track down who's responsible.
Former U.S. Assistant Secretary for Homeland Security Juliette Kayyem and former FBI Assistant Director Thomas Fuentes say combing through the evidence in the Boston Marathon attack will be a slow process because of the volume of material to review.
Carlos Arredondo heroically jumped into action after the bombs exploded near the Boston Marathon finish line. Trained by the Red Cross, Arredondo says he tried to stop a severely wounded victim from bleeding. Jeff Bauman survived, but later had both legs amputated.
Arredondo made headlines years ago under very different circumstances. One of his sons, a 20-year-old Marine named Alexander, was killed in Iraq by a sniper in 2004. Arredondo received the devastating news on his birthday. Distraught, the grieving father set a van on fire and suffered serious burns.
He later created a tribute to his son on his car and drove to other military families in mourning to provide comfort. Tragically, his other son took his own life in 2011.
Bill Forry, a friend of the Richard family, says the community in his town will support the family during this difficult time and will remember 8-year-old Martin as a gifted athlete, a bright student, and a leader among his peers. He died in the Boston Marathon attack that left his sister and mother seriously wounded.
Forry describes the close-knit family of five as the type of people anyone would want living next door. "The neighborhood revolves around them and their house. They're so inviting and welcoming. They've done so many things in our community, in Dorchester, to improve life there," he says.
Denise Richard was hit in the head with shrapnel and is still recovering. Her young daughter Jane, who loves Irish step dancing, lost a leg in the blast. "She's a tough kid, energetic. And I don't think her dancing days are over," Forry says.
Ron Brassard describes the fear and confusion after the Boston Marathon attack, and he tells Anderson Cooper about the runners who tried to help him immediately following the blast. His wife was also hurt and his friend lost both legs.
