BOSTON (CN) - Jurors have two different images Tuesday as they consider the fate of Boston Marathon bomber Dzhokhar Tsarnaev: one of a "bloodthirsty" extremist and the other of "an adolescent doing adolescent things."
For his admitted role in largest terrorist attack in the United States since Sept. 11, 2001, Tsarnaev, 21, faces 15 counts of criminal acts. He also faces another 15 counts for the measures he took in his attempt to escape capture. Seventeen of the 30 counts carry the death penalty.
In total, four people were killed and more than 260 were injured on April 15, 2013. Of these, 17 suffered amputations.
Though he does not face a criminal count for it, Tsarnaev is also blamed with inadvertently killing his brother and co-conspirator in the attacks, Tamerlan, by running him over with the SUV they stole while police were trying to subdue the man.
Assistant U.S. Attorney Aloke Chakravarty began closing statements Monday by reminding the jury that Tsarneav, a naturalized U.S. citizen who came to America with his family as refugees from Kyrgyzstan, wanted to "awake a holy war."
"He wanted to terrorize this county," Chakravarty said of the ethnic Chechen. "He wanted to punish America for what it was doing to his people. And that's what he did."
Prosecution went over the entire timeline of events, starting with a video of the bomb Tsarneav planted going off.
The footage shows Tsarneav approaching a row of kids behind a metal barrier separating the sidewalk from the marathon on the street. A tree almost obscures him from view.
People at the restaurant behind him are clapping for the runners, talking and smiling.
Then, everyone stops abruptly and looks towards the finish line, puzzled. Moments later, the bomb next to them goes off, and chaos erupts.
The smokes lifts quickly and the scene is inundated with ripped clothing, blood pooling, people running with their mouths open in terror. Others are dragging themselves away on their bellies because they are unable to stand. Many have bones protruding from gaping holes in their flesh.
Tsarneav can be seen looking over his shoulder and pushing people out of the way as he flees.
While this footage plays yet again in the courtroom, Tsarneav begins to nervously pick at his lips.
The prosecution details how Tsarneav "cooly" continued on with his day, stopping by Whole Foods and then going to his dormitory at the University of Massachusetts at Dartmouth, where he had time for a workout.
"Three days later when their faces were all over the news, they sprung back into action, again in a coordinated style," the prosecution said.
With plans to detonate more bombs in New York City, the Tsarnaevs targeted a cop, killing him on April 18 while trying to steal his gun. They carjacked an SUV next, to make themselves harder to track.
Paraphrasing testimony the jury heard from the driver they kept hostage, Chakravarty said that the Tsarnaevs "were talking to each other, like partners, in a foreign langue, like a team."
The brothers also took turns wearing the same hat on that day, the prosecutor added.
