The defense has rested its case in the federal death penalty trial of Boston Marathon bomber Dzhokhar Tsarnaev.

Tsarnaev's lawyers ended their case Tuesday after calling just four witnesses.

The trial was continued till Monday when closing statements will be presented.

In opening statements, the defense admitted that Tsarnaev participated in the bombings but said his late older brother, Tamerlan, was the mastermind of the 2013 terror attack.

The defense called a cell site analyst who showed that Tsarnaev was at the University of Massachusetts-Dartmouth when Tamerlan purchased components of the two bombs.

If Tsarnaev is convicted, the same jury will hear additional evidence to decide whether he should be put to death or spend the rest of his life in prison.

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