Update: Federal prosecutors rest their case in the first phase of the death penalty trial of Boston Marathon bomber Dzhokhar Tsarnaev Monday, according to multiple media tweets.

The trial will now be turned over to the defense team, who have already acknowledged their client’s involvement in the marathon attacks but have argued Tsarnaev was influenced by his older brother, Tamerlan, who was killed in a shootout with police in Watertown days after the bombings.

Earlier: The prosecution in the death penalty trial of Dzhokhar Tsarnaev is expected to call its closing witnesses to the stand Monday morning, and conclude its case against the surviving Boston Marathon bomber with disturbing images of the carnage caused by the homemade bombs planted at the finish line nearly two years ago.

After the prosecution rests, the trial will be turned over to the defense, which, on day one of the proceedings, admitted that Tsarnaev played a role in the bombings. The defense has argued that their client was influenced by his older brother, Tamerlan Tsarnaev, who died in a shootout with police in Watertown a few days after the April 15, 2013 bombings.

By the end of this week, jurors could be asked to determine whether Dzhokhar is guilty of the 30 counts he faces, 17 of which could be punished by the death penalty. If convicted, Tsarnaev’s fate – life in prison or the death penalty – would be determined during a second phase of the trial.

Prosecutors plan to call the medical examiners who performed the autopsies on 23-year-old Boston University grad student Lingzi Lu and 8-year-old Martin Richard to the stand Monday.
