April 24, 2013 Slain Suspect Bought Fireworks 2 Months Before Attack; Wife Vows Cooperation with Probe ---------------------------------------------------------------------------------------- Investigators say the Tsarnaev brothers may have learned to make the pressure-cooker bombs they used by reading the al-Qaeda magazine "Inspire." The older brother bought fireworks from a store in New Hampshire two months before the attack. On Tuesday, lawyers for his wife, Katherine Russell, said she is cooperating with the investigation. Amato De Luca: "She is doing everything she can to assist in the ongoing investigation." Miriam Weizenbaum: "The injuries and loss of life to people who came to celebrate a race and a holiday has caused profound distress and sorrow to Katie and her family. The reports of involvement by her husband and brother-in-law came as an absolute shock to them all." .
