In the midst of the blast's debris, ATF (Federal Alcohol, Tobacco and Firearms) and FBI agents evaluate the damage.
On the street outside the building, a victim holds a towel to his gauze-wrapped head.
In one of the most iconic photographs from the day, firefighter Chris Fields cradles Angel Baylee Almon, who had been in the building's Stars and Stripes Daycare Center on the first floor. Almon died in the explosion, just 24 hours after her first birthday.
