Through the day Monday, we received information from quite a few different sources. Some of it was accurate and, of course, some of it was conjecture.
The explosions - two bombs exploded at about 2:50 p.m. Monday in Boston's Copley Square. They were on the same side of the street, 100 yards apart and about 11 seconds apart.
Injuries - Three people were killed and more than 140 were injured. An 8-year-old boy, Martin Richard, was one of the fatalities.
Investigation - The FBI took charge of the investigation and served a warrant late Monday on an apartment in Revere, a Boston suburb. No arrests have been made. There is no official word on suspects.
Security - The area around Copley Square was closed Tuesday morning, along with exit ramps from major highways to the area. The FAA closed airspace to low-flying aircraft within 3.5 miles from the site. Security was tightened at Boston's Logan Airport.
From the Associated Press, we have a short list of what has been confirmed. Remember, investigation is just beginning.
