Prosecutors are expected to wrap up their case against Boston Marathon bomber Dzhokhar Tsarnaev (joh-HAHR' tsahr-NEYE'-ehv) with testimony from medical examiners who'll describe the fatal injuries to two people, including an 8-year-old boy.

The prosecution is expected to rest its case on Monday in the first phase of the trial. The same jury that considers 30 federal charges against Tsarnaev will hear additional evidence during the trial's second phase to determine whether Tsarnaev is sentenced to death or life in prison.

During opening statements, Tsarnaev's lawyer admitted he participated in the bombings, but said his older brother, Tamerlan, was the mastermind of the terror attack.

Three people were killed and more than 260 were injured when two pressure cooker bombs exploded near the marathon finish line on April 15, 2013.
