JACKSONVILLE BEACH, Fla. (AP) — Seconds after the Boston Marathon bombs exploded, David Green pulled out his smartphone and took a photo of the chaos developing a couple hundred yards in front of him — the smoke, the people running in panic.
The Jacksonville businessman then put his phone back in his pocket and went to help the injured. It wasn't until Thursday, when officials released surveillance video of the two suspects in the twin blasts, that Green realized what he had — a picture of 19-year-old Dzhokhar A. Tsarnaev, distinctive in his backward white baseball cap, walking away from the scene.
Tsarnaev, known to the FBI as Suspect No. 2, was still on the run Friday, prompting authorities to shut down the city of Boston and its western suburbs and warn residents to stay inside with their doors locked while police and federal agents hunted him down.
Tsarnaev's older brother, 26-year-old Tamerlan Tsarnaev, identified as Suspect No. 1, was killed overnight, officials said.
Green, back at his home in Florida, wore his yellow and blue Boston Marathon jersey as he talked about his now-famous photo, his finisher's medal from the race propped on a shelf in his home office.
Green, 49, had finished Monday's marathon in 3 hours and 17 minutes, about an hour before the blasts. An avid endurance athlete and CEO of 110% Play Harder, a sportswear company, it was his first Boston Marathon and four of his co-workers had come to the finish line to cheer for him.
After he recovered, he went back to Boylston Street, where the finish line is located, to watch the rest of the race with his friends. He realized his phone was dying, so he went into a nearby store with a recharging station.
About 15 minutes later, he was walking back to his friends when the first bomb went off.
