Emerson College student Laura Franzini, a former Globe co-op, captured this video after the explosion.
"I was in the nearby office building at 399 Boylston when I heard about the explosions on Twitter and a couple colleagues and I went down to check it out. The video was shot between 3:15 and 3:30pm. I was standing at the corner of Boylston and Clarendon. The videos show people--Marathon volunteers, police, and civilians--clearing the street so that trucks and emergency vehicles could get by, and police ushering people away from the scene.''
Emerson student Charlotte Haab also took this video:
