Tsarnaev Defense Rests Case in Bombing Trial

Accused Boston Marathon bomber Dzhokhar Tsarnaev's defense lawyers rested their case Tuesday after trying to shift jurors' focus onto his older brother, Tamerlan, who they say masterminded the April 15, 2013 attack. On Tuesday, the defense also called computer forensic analyst Mark Spencer, who inspected digital evidence taken from the brothers' laptops. He said he found Internet searches for the Boston Marathon, gun stores, wireless transmitters, detonators and a "fireworks firing system" on a laptop the defense says was Tamerlan's. Spencer also said that copies of the al Qaeda associated magazine Inspire — including an article called "Make a Bomb in The Kitchen of Your Mom," which prosecutors highlighted earlier in the trial — were created on Tamerlan's computer then transferred via thumb drive to Dzhokhar's.
