[Update, 9:38 p.m. ET] Dr. Allan Panter, who was near the finish line waiting for his wife who was running the race, told CNN he was standing about 20 to 25 feet from the first blast. He said he treated victims on the street after the explosion.

"I saw at least six to seven people down next to me," he said. "They protected me from the blast. One lady expired. One gentleman lost both his (lower) limbs. Most of the injuries were lower extremities. I could not figure out why the young lady had expired. I could not find any injury on her thorax."
[Update, 9:28 p.m. ET] Bill Iffrig, seen in video wearing an orange tank top and being blown over as he approached the finish line, told CNN's Piers Morgan that he was feeling OK after the blast.
"I got down to within about 15 feet of the finishing apron and heard just tremendous explosion, sounded like a bomb went off right next to me, and the shock waves just hit my whole body and my legs just started jittering around," he said. "I knew i was going down and so i ended up down on the blacktop."
Iffrig, 78, said he was assisted by one of the event volunteers, who helped him up so he could finish the race. After that, the worker looked for aid for Iffrig, who had just a scratch from his fall.
"He insisted on getting a wheelchair over there so we started to do that, but then before that was rounded up, i said my hotel's about six blocks away so I think I can make it okay. So they let me get out of there and I went on home to my wife."
