Boston Marathon bomber Dzhokhar Tsarnaev will get a chance to break his long silence when a judge formally imposes the death sentence recommended by a jury.

Tsarnaev's sentencing hearing is scheduled for Wednesday in U.S. District Court in Boston.

More than 20 bombing victims are expected to give impact statements. Tsarnaev will also be given a chance to speak.

Tsarnaev's sentence has already been decided by the jury that recommended the death penalty. Judge George O'Toole Jr. is required to impose that sentence.

Some legal experts say Tsarnaev could decide to apologize, make a political speech to justify the bombings or say nothing at all.

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