The man accused of bombing the Boston Marathon in 2013 has been found guilty of all 30 charges that he faced, many of which carry the death penalty, BBC News reports.

The jury in Massachusetts will now decide what sentence 21-year-old Dzhokhar Tsarnaev will receive.

Three people were killed and more than 260 injured when the bombs exploded at the finish line in April 2013.

His lawyers admitted he played a role in the attacks but said his older brother was the driving force.

The guilty conviction was widely expected. In the next phase of the trial, Tsarnaev's legal team will push for him to be given a life-in-prison sentence instead of death.

His chief lawyer, Judy Clarke, specializes in defending high-profile clients facing the death penalty, including the Unabomber, Ted Kaczynski.

Tsarnaev's defense team say he took part in the bombing, but argue that his elder brother, Tamerlan, was the mastermind of the attack who influenced Tsarnaev into participating.

Prosecutors portrayed the brothers as equal partners in a plan to "punish America" for wars in Muslim countries.

Although Tsarnaev's defense team had repeatedly appealed for a change of venue, Boston is not known for its support of capital punishment. Massachusetts abolished the practice in 1984 and has not executed anyone since 1947.

Tsarnaev is an ethnic Chechen. His family moved to the U.S. about a decade before the bombings.
