Boston Marathon Bomber Dzhokhar Tsarnaev Found Guilty

A Boston jury has found Dzhkohar Tsarnaev guilty on the first 18 charges related to the deadly 2013 Boston Marathon bombing, which means Tsarnaev could face the death penalty. The court is announcing the verdicts for the rest of the 30 counts against Tsarnaev as of this report.

Wearing a dark jacket over a blue shirt, Dzhokhar Tsarnaev entered the courtroom and took his seat next to his attorney Judy Clarke. As the verdicts were read, Tsarnaev did not react and has not looked at the jurors.

Twin blasts near the finish line of the April 2013 Boston Marathon killed three people and injured some 260 others. In a still image taken just before the explosion, Tsarnaev can be seen apparently dropping a backpack that prosecutors said contained a bomb in the middle of the crowd, just behind eight-year-old Martin Richard, who was killed in the blast. Tsarnaev also faced charges relating to the murder of MIT police officer Sean Collier three days later.

From the outset of the trial, Tsarnaev's attorneys had argued not that Tsarnaev was free from blame for the horrific allegations lodged against him, but that he was under the influence of his older brother Tamerlan Tsarnaev -- a strategy that legal analysts told ABC News was not designed to win the trial, but to avoid the death penalty later in a penalty phase to follow. Tamerlan Tsarnaev was killed in a police shootout days after the marathon bombing.
