A "controlled explosion" was announced an hour after two bombs went off at the Boston Marathon finish line within a second of each other. However, authorities later waved off the incident as the result of an apparent electrical fire.
ABC News reported that an explosion was heard at 3:55 p.m., a minute after a Boston Globe Tweet announcing that the explosion was imminent.
If indeed the bomb squad did set off a third device, questions arise, questions that the press does not appear to have addressed:
Why did that bomb not go off? Was its timer or cell phone link bad?
Did authorities discover a black backpack and decide to clear the area and electronically, or otherwise, trigger it?
Who planted the bomb? The two fatal bombs were reportedly carried to the scene in backpacks worn by each brother. Perhaps that device was dropped off by the brothers in a separate trip. But this is a question that should be examined.
Instead what we have is cursory media coverage and a statement that the third explosion was simply the result of an unrelated electrical fire. The source of that statement may have been unaware of the Globe's Tweet announcing an explosion.
News reports leave questions
From a Google description of an ABC page (the first link went bad after I visited it, so I included the alternate link, which changes the time from 3:54 p.m. to 4:55 p.m.):

From the ABC page:
4:55 p.m. ET: There was also a controlled explosion on Boylston St., not one of the three incidents, says Commissioner Ed Davis. [According to a Davis Tweet, there was to be a "controlled explosion" on Charles Street.
[We note that it seems likely the Globe "controlled explosion" Tweet occurred at 3:54 p.m., there being a three-hour time difference between Twitter's headquarters in California and Boston. (At first, I assumed 2:54 p.m. for the Tweet, but that is a questionable assumption.)]
The Tweet said the explosion was to occur across from the library, but then apparently there was backtracking alleging an electrical fire at the library.
Media coverage of these (this?) event remains scanty.
Here's the ABC timeline I found on the second ABC link:

12:47 a.m. ET: Sources tell ABC News authorities are looking for any friends and associates of the 20-year-old Saudi national.
12:07 a.m. ET: ABC News’ Aaron Katersky reports the working theory about the bombs, according ti Massachusetts law enforcement, is that they were small, crudely made devices hidden in bags or backpacks, planted either during the race or immediately prior and detonated remotely, possibly with a cell phone. Officials here have subpoenaed cellphone records.
11:50 p.m. ET: ABC News can confirm that one of the people law enforcement officials are talking to is a 20-year-old Saudi national at a Boston hospital. Sources tell ABC News that he is here legally on a student visa and that his visa is clean with no apparent criminal history.

10:35 p.m. ET: Ron M. Walls, chairman of Boston’s Brigham and Women’s Hospital, told reporters that the hospital has 29 total patients, 8 of whom are in critical condition. Walls said that the only shrapnel they have seen in injured victims is material from the street – bits of metal, soda cans and anything that was really close to a blast and became fragmented. He said there have been no reports of ball bearings or anything that seemed as if it may have been placed into the explosion to cause more damage.
