He is also charged in the death of a polcie officer, shot wheil he was on the run.

Tsarnaev had pleaded not guilty to 30 federal charges in connection with the attacks and the killing.

March 30: After four weeks, the prosecution rests its case.
March 31: Tsarnaev`s lawyers wrap up their defense.
April 7: Jurors begin deliberations to determine whether Tsarnaev was guilty on the 30 counts. If convicted, 17 of the charges carry the possibility of the death penalty, which could be handed down during the trial`s sentencing phase.

April 10: Judge George O`Toole rules the trial`s sentencing phase will begin on April 21.
