Jurors in the trial of Boston Marathon bomber Dzhokhar Tsarnaev have been given a glimpse of his computer contents, which included extremist materials such as the Al-Qaida-produced magazine, Inspire.

An FBI computer forensics expert began testifying Thursday about materials collected from Tsarnaev's computer.

One file is called "Complete Inspire." In the indictment, prosecutors allege he downloaded a copy of Inspire that included instructions on how to build bombs with pressure cookers, the kind of device used in the marathon bombing.

During opening statements, a prosecutor cited Inspire as one way Tsarnaev and his older brother, Tamerlan, became radicalized.

Dzhokhar Tsarnaev could face the death penalty if convicted. Tamerlan died after a gunfight with police.

Three people were killed and more than 260 were injured in the 2013 marathon bombings.
