Boston Marathon Bombing

The Boston Marathon Bombing was a domestic terrorist attack that occurred on April 15, 2013 in Boston, Massachusetts. Dzhokhar and Tamerlan Tsarnaev, two Kyrgyz-American brothers of Chechen descent, created two pressure cooker bombs using instructions published by Al Qaeda in the Arabian Peninsula. They placed the two bombs, which they had concealed in backpacks, close to the finish line of the Boston Marathon about 100 yards apart and left the area. The bombs detonated 12 seconds apart around 2:50 p.m. The attack killed three and injured hundreds of runners and spectators, leading to a manhunt for the two men during which they carjacked a man on MIT's campus and killed a police officer. Tamerlan himself subsequently died after he was shot by law enforcement and his brother ran him over with a stolen SUV while attempting to flee.
