Dzhokar Tsarnaev, one of the two Boston bombers, has been sentenced to death, reports NECN.
The jury's verdict will be appealed by a higher federal court in a tedious process that could take several years.
Each juror filled out a 24-page form to help determine whether or not Tsarnaev's actions warrant the death penalty.
For Tsarnaev to be eligible for the death penalty, however, the jury members only needed to provide a unanimous "yes," according to Boston.com.
The jurors appeared to be nearly unanimous in regards to Tsarnaev's responsibility for the attack, which killed three and injured more than 260 on April 15, 2013.
Tsarnaev's defense attorneys argued it was the older and deceased brother, Tamerlan, who convinced him to participate in the attack and he was known as a nice boy beforehand.
But it was ultimately determined Tsarnaev showed no remorse for what he did and acted on his own free will.
