Defense attorney [[Judy Clarke]] admitted that Dzhokhar Tsarnaev had placed the second bomb and was present at the murder of Sean Collier, the carjacking of Dun Meng, and the Watertown shootout, but she emphasized the influence that his older brother had on him, portraying him as a follower.<ref>{{cite conference|chapter-url=https://s3.amazonaws.com/s3.documentcloud.org/documents/1681442/tsarnaev-dzkokhar-trial-transcript-3-4-2015-clarke.pdf |title=United States v.

On July 30, 2020, Tsarnaev's death sentence was reversed by the [[United States Court of Appeals for the First Circuit]], which found that, during jury selection, the District Court did not properly screen prospective jurors on how much they had heard of the case. The First Circuit vacated the death sentence and three of the other thirty convictions against Tsarnaev, and ordered a new penalty phase jury trial with fresh jurors, leaving the decision of a new change of venue to the District Court. Tsarnaev's remaining convictions still carried multiple life sentences, ensuring that he would remain in prison regardless of the results of the new trial.<ref name="cnn appeal july312020">{{cite web | url = https://www.cnn.com/2020/07/31/us/boston-marathon-bomber-dzhokhar-tsarnaev-sentence-vacated/index.html | title = Appeals court vacates Boston Marathon bomber's death sentence, orders new penalty trial | first = Sonia | last = Monge | date = July 31, 2020 | access-date = August 1, 2020 | work = [[CNN]] }}</ref> The United States government appealed this ruling to the [[U.S. Supreme Court]], which granted certiorari in the case ''United States v.
