NYT: A third explosion was heard just before 4 p.m., about an hour after the first two blasts, at the nearby John F. Kennedy Library. The police later said that episode may have been unrelated.  (Question: Do NYT writers feel glee when they write a sentence like that?)

A person briefed on preliminary developments in the investigation said that members of Boston’s Joint Terrorist Task Force were at Brigham and Women’s Hospital interviewing a wounded man seen running from the scene of the two blasts, near 671 Boylston Street. The person said that police investigators had contacted the local gas and electric company and determined that the explosions were not related to gas or electrical service.

The authorities also found a device at St. James and Trinity Streets that did not explode, the person said, and two other devices were found, including one in Newton, outside of Boston.
