I'm David Greene.
Let's work through what we know about yesterday's explosions at the Boston Marathon.
INSKEEP: Hours of struggle and accomplishment changed in an instant. Mirabelle Garcia had just finished running her ninth Boston Marathon.
MIRABELLE GARCIA: As soon as I crossed the finish line, I heard the explosion. And I turned back, and that's when I said, what's going on? And everybody was just running everywhere, yelling, freaking out, crying.
GREENE: She saw glass raining down. She saw the blood of runners and spectators.
GARCIA: And I know that some of the people that were right behind me got badly hurt. And it looked like a movie.
INSKEEP: Amazingly, some runners kept moving toward the finish line. In the hours after the explosions, President Obama warned against jumping to conclusions.
PRESIDENT BARACK OBAMA: We're still in the investigation stage, at this point. But I just want to reiterate, we will find out who did this, and we will hold them accountable.
GREENE: That was President Obama yesterday. Transcript provided by NPR, Copyright NPR.
