MO of second blast timed to hit first responders is classic AQ, though not unique to them.Authorities are investigating a report of two explosions at the finish line of the Boston Marathon.
There were two booms heard from near the finish line inside the Fairmount Copley Plaza Hotel.
It happened around 2:45 p.m. outside Marathon Sports on Boylston Street, according to WBZ-TV's Lis Hughes, who was near the scene covering the marathon.
There were two "incredibly powerful explosions just seconds apart," according to Hughes.
| Update 4:29 ET: Third and fourth unexploded bombs found and dealt with. Number of dead keeps changing, also number of injured. New York Post suggests this may have been transferred from the New York marathon that was cancelled in November. May the miscreants be found quickly, with cell phones and laptops aplenty. |
