In a filing that extensively cites jurors’ social media feeds, lawyers representing Boston Bomber Dzhokhar Tsarnaev appealed his conviction on Monday, saying it was impossible for their client to receive a fair trial in Eastern Massachusetts.

During his sentencing hearing this afternoon, Boston bomber Dzhokhar Tsarnaev addressed the court and members of his victims’ families for the first time. “I am sorry for the lives I’ve taken, for the suffering I have caused, and for the terrible damage I have done,” he said, reportedly while crying.

After weeks of testimony and three days of deliberations, a federal jury sentenced Dzhokhar Tsarnaev to death by lethal injection today. Last month, the 21-year-old was found guilty of 30 charges related to the bombing at the finish line of the 2013 Boston Marathon.

Accused Boston bomber Dzhokhar Tsarnaev's former college roommate testified today that he behaved as normal in the days following the bombing. "He slept a little bit more, but that was it," Andrew Dwinells said.
