Day 8: Tsarnaev's Friend Turns Against Him

The Finish Line podcast is hosted by WBUR’s David Boeri and The Boston Globe’s Kevin Cullen, who share their insights and analysis in the federal death penalty trial of admitted Boston Marathon bomber Dzhokhar Tsarnaev.

Any hope the defense has of saving Tsarnaev's life is in convincing the jury that he was just a deadbeat, pot-smoking college student, under the sway of his older brother Tamerlan, the real jihadi. A demonstration of what they're up against - say Boeri and Cullen - came in Day 8 of the trial, with the first testimony from one of Tsarnaev's old friends, Stephen Silva.
