About a dozen anti-death penalty protesters are demonstrating outside the federal courthouse as a jury gets ready to hear evidence on what punishment Boston Marathon bomber Dzhokhar Tsarnaev (joh-HAHR' tsahr-NEYE'-ehv) should receive.

Tsarnaev's lawyers and a prosecutor met with Judge George O'Toole Jr. for nearly an hour Tuesday morning as the penalty phase of Tsarnaev's trial was about to begin.

Tsarnaev was convicted on all 30 federal charges against him. The same jury will now hear evidence on whether he deserves life in prison or the death penalty.

Tsarnaev's lawyers say he doesn't deserve death because he was a 19-year-old under the influence of his domineering brother.

Prosecutors contend Tsarnaev deserves the ultimate punishment.

Three people were killed and more than 260 were injured in the 2013 bombings.
