July 4 previously a target. The surviving suspected Boston bomber, Dzhokhar Tsarnaev, told interrogators that he and his brother considered setting off their bombs on July 4, then shifted their plans to the earlier date of the Boston Marathon, US officials have said.
How bombs were made. Some investigators believe the bomb designs came at least partly from an article titled "How to build a bomb in the kitchen of your mom," published a couple of years ago by Al Qaeda in the Arabian Peninsula's Inspire magazine. It was also republished earlier this year in a glossy brochure entitled the "Lone Mujahid Pocketbook."
College-friend suspect out on bail. A 19-year-old Massachusetts resident accused of lying to federal investigators was freed on $100,000 bail Monday.
Robel Phillipos, a friend of Dzhokhar Tsarnaev, will be under the custody of his mother and must wear a GPS ankle bracelet, US Magistrate Judge Marianne Bowler ordered in federal court in Boston.
In addition to Mr. Phillipos, two other friends are charged with efforts to impede the investigation – including removing a backpack of evidence from Tsarnaev's dorm room after they knew their friend was wanted by the Federal Bureau of Investigation.
