Dr. Ron Medzon, an emergency room physician at Boston Medical Center, recalls treating victims injured in the bombing.
The death toll in New York following Superstorm Sandy now tops 40, including at least 19 on Staten Island, where hundreds of homes were destroyed.
Staten Island is sometimes called the forgotten borough, and residents said they have felt forgotten in the wake of the storm.
The Red Cross is now on the scene, offering bottled water and ready-to-eat meals at five distribution centers.
Staten Island is also where the New York marathon will start on Sunday. More than 40,000 runners will line up at the Verrazano-Narrows Bridge toll plaza.
Mayor Michael Bloomberg decided the marathon should go on, despite the disaster.
Reverend Steve Martino of the Movement Church on Staten Island has set up a small distribution center at New Dorp Beach with a few volunteers.
“We’re having an issue with runners now, people are arriving to run the marathon, they’ve booked hotel rooms but the hotels are refusing to evict the people who came there when they lost their houses,” Martino told Here & Now’s Robin Young. “If this mayor is worried about his legacy he shouldn’t worry about a marathon, he should worry that the people are getting what they need and that they’re being helped.”
