Boston bombing suspect Dzhokhar Tsarnaev admitted to FBI interrogators that he and his brother originally planned their assault as a suicide bombing on the Fourth of July. According to an official, they planned to use pressure-cooker bombs and other homemade explosive devices, but they finished building the bombs early and pushed up the date to Patriots’ Day, April 15. The brothers drove around Boston before settling on the marathon finish line as a target. He also said they watched online videos of radical Islamic cleric Anwar al-Awlaki.
