Pierce• Boston-based Charlie Pierce of Esquire’s Politics Blog calls in at 10:30am ET / 7:30am PT to update us on the Boston Marathon Bombings

The bombs that blew up seconds apart at the finish line of one of the world’s most storied races left the streets spattered with blood and glass, three dead, including an 8-year-old boy, more than 140 wounded and gaping questions of who chose to attack at the Boston Marathon and why.

The 8-year-old boy killed in the explosions at the Boston Marathon has been identified as Martin Richard, The Boston Globe reported. No suspects have been identified in the case, which federal authorities are classifying as an act of terrorism.

President Obama said he ordered the “full resources” of the federal government to respond to the Boston bombings on Monday, and that he also called for increased security around the U.S. as necessary. Notably absent from his remarks was the word “terror,” though federal investigators are classifying the bombings as a terror event.

• Early Tuesday, law enforcement officials went to an apartment in the north Boston suburb of Revere, where they interviewed two men and were seen by reporters removing two trash bags and a duffle bag. It is still unclear what significance, if any, this had with regard to the bombing investigation.
