"I Gave My Boston Marathon Photos to the FBI"

April 19, 2013— -- On Monday April 15th, Ben Levine was snapping photos of runners from his office window on Boyle Street, one story above the Boston Marathon's finish line. Ben, 24, had just received the camera as a present from his parents.

A handful of people had gathered at the office to watch the marathon, an annual treat for co-workers and clients who go there to enjoy the privileged view.

Ben, a PR professional, had snapped a couple dozen photos of the marathoners and the finish line when out of the corner of his eye he saw the first explosion.

He immediately ducked for cover but then kept snapping away. He raised his arm over the window and without looking he took as many photos as he could.

Many thoughts went through Ben's mind in the next few seconds—perhaps the explosion was a firecracker gone wrong and somebody was going to get into a lot of trouble, but above all, he kept snapping photos. Not long afterwards, Ben and his co-workers evacuated the building.

In the aftermath of the bombings, Ben started to feel guilty because of his decision to continue taking pictures instead of helping the injured.

However, Ben's photographic instinct was not in vain. A day later he turned in his photos to the FBI hoping that some of them might shed some clues into the bombers' identity.

It will be hard for him to forget the carnage he witnessed that day.
