BOSTON » Lawyers for Boston Marathon bomber Dzhokhar Tsarnaev (joh-HAHR’ tsahr-NEYE’-ehv) will try to blunt the testimony of an FBI computer expert who described extremist materials found on his computer and other devices.

Tsarnaev’s lawyers on Monday are expected to cross-examine Kevin Swindon, a supervisory special agent for the cyber squad at the FBI’s Boston office. Swindon testified Thursday that Tsarnaev had Inspire magazine, an al-Qaida publication, and other radical materials on his computer.

Tsarnaev’s lawyers contend that most of the material found on his computer was typical for college students, including cars, girls and school work.

The 21-year-old Tsarnaev faces the possibility of the death penalty for carrying out the deadly 2013 attack with his brother. Three people were killed and more than 260 were injured.
