This is What the Boston Marathon Attack Looked Like from a Runner’s Perspective

A new view of the first explosion has emerged, this one shot from a runner’s perspective.

It, like virtually everything else related to this awful story, is chilling.

“This is a video my mom recorded of the explosion,” the YouTube description reads. “We are so lucky we got out of there when we did. My mom didn’t finish the race but we are all safe and that’s what matters. My heart goes out to the victims.”
