Also Monday, lawyers released new video showing Tsarnaev and his friends.
There's no question bombing suspect Dzhokhar Tsarnaev and Azamat Tazhayakov were good friends. Evidence of that was shown in federal court. A new video shows them the day after the Marathon bombings, heading into the gym at UMass Dartmouth - where they attended college - and then leaving.
Another photo released shows of Tsarnaev, Tazhayakov and some other friends hanging out in Tazhayakov's New Bedford apartment, just weeks before the bombings.
The question for jurors now is whether Tazhayakov obstructed justice by conspiring to destroy property belonging to Tsarnaev, including Tsarnaev's laptop and a backpack containing fireworks.
The prosecution's last witness against Tazhayakov was FBI Special Agent John Walker, who testified about his internet search history after the FBI released images of the bombing suspects, but before they were caught.
Tazhayakov reportedly looked at numerous stories about the suspects, and at one point even searched his own name on Google.
Defense attorney Matthew Myers says his client is only guilty of being friends with the accused bomber, and pointed to another high profile case to make his point.
"Aaron Hernandez spent a lot of time with Tom Brady, right? He did, right?" Myers asked reporters outside of court on Monday. "Do you think Aaron Hernandez ever had conversations with Tom Brady about what he was potentially doing? I'm not making an evaluation of his case right now."
After the prosecution rested, attorney Myers did the same, without calling any witnesses, even though Tazhayakov's father says his son wanted to testify.
"We didn't feel like we wanted to start switching the burden of proof. We know when we start putting witnesses on the jury starts focusing on our case. They should be focused on the prosecutor's case, not ours," Myers said.
The lawyer calls the biggest hole in the case the credibility of law enforcement officials, who he says have repeatedly contradicted themselves on the stand.
Tazhayakov's father says he's hopeful jurors will do the right thing.
"I believe in the people of Boston and I trust them and I just want to hope that they will make their decision based not on emotions but on common sense and the facts that were proven," he said through a translator outside court Monday.
Lawyers for both sides will be back in court Tuesday to talk about the instructions the judge will give to the jury. After closing arguments on Wednesday morning, the jury gets the case.
Tazhayakov faces up to 20 years in prison.
