Dr. David Schoenfeld tells Anderson Cooper and Dr. Sanjay Gupta what it was like in the ER when the suspected Boston Marathon bombers were brought there last week. The doctor and the other staff had been treating victims of the attack and were on alert for more patients. Schoenfeld, who lives in Watertown, called his colleagues when he heard the gunfire and explosions early Friday.
"The folks in our department did a fantastic job preparing the emergency department for any number of trauma patients that were going to come in. So by the time I got there, the trauma bays were staffed and ready; the teams were divided up. We had additional staff coming in. The OR was, you know, ramping up. The whole hospital was ramping up," he said.
When suspect #1 arrived at Beth Israel Deaconess Medical Center with gunshot wounds and other injuries, Schoenfeld says their team did what they do with all trauma patients and tried to resuscitate him. He later died at the hospital.

Malala Yousufzai, 14, is now in the hands of medical experts in England. The Pakistani teen was shot in the head and neck by the Taliban last week when riding home in a school van with other classmates in the Swat Valley region, near the border with Afghanistan.
Malala was targeted by the gunmen for speaking out about girls’ rights to education. Last year when asked why she risks her life, she told CNN’s Reza Sayah, "I shall raise my voice...I have rights. I have the right of education. I have the right to play. I have the right to sing. I have the right to talk. I have the right to go to market. I have the right to speak up."

Less than two weeks have passed since 22-year old violist Petra Anderson was shot four times in theater 9, but she is on the road to recovery with the help of her doctors, family and the healing power of music.
CNN’s Dr. Sanjay Gupta explained how music may be helping Petra recover. "If you think about trying to sing a song, for example, there are several different parts of your brain that are immediately harnessed," Gupta said. The tunes are often played by her boyfriend, who is a professional clarinet player. "In someone who is just learning to walk, if you find a song with a particular cadence to it, you can learn how to reestablish your rhythm," said Gupta.
Petra's recovery has been considered a "miracle," because the bullet that went through her brain was just millimeters from striking in a way that could have been more damaging and possibly deadly. "The bullet, if it had gone through a particular blood vessel in there, and there are several that are large, that would have been a catastrophic injury. If it would have been lower within the brain, it could have injured the brain stem," explained Gupta.
