Boston bomber Dzhokhar Tsarnaev will appear at a court hearing today and come face to face with his victims for the first time.

The 19-year-old will appear at a Boston courthouse three months after the bombings at the Boston Marathon which killed 3 people and injured 264 others.

The courtroom is expected to be packed for the arraignment of Tsarnaev this afternoon, with spaces reserved for the victims' families.

The hearing will be broadcast for the media and this will be Tsarnaev's first public appearance since his arrest.

Many of the victims and their families will be at the court hearing where Tsarnaev faces three murder charges for the bombing and another murder charge of a police officer at MIT. Dzhokhar has also been charged with using a weapon of mass destruction.

His charges can lead to the death penalty, which state prosecutors believe the defense attorneys will try to avoid.

Dzhokhar and his late brother Tamerlan Tsarnaev built home-made bombs with a pressure cooker and planted the twin bombs at the Boston Marathon finish line on April 15.

Tsarnaev, 26, was killed during a police confrontation on April 19. Dzhokhar, 19, was captured alive the next day after one of the nation's biggest manhunts. He was in critical condition when he was finally apprehended by police in a boat outside of a residence in Watertown, Mass. He had suffered injuries to the throat and chest. He was transferred to prison after recovering at a hospital.

Tsarnaev had scrawled a note on the walls of the boat where he hid. His message read: "I don't like killing innocent people. I can't stand to see such evil go unpunished.. We Muslims are one body, you hurt one you hurt us all."

The three victims who lost their lives are Martin Richard, 8; Krystle Marie Campbell, 29; and Lingzi Lu, 23. The police officer who was killed by the Tsarnaev brothers at MIT is Sean Collier.
