As the trial of accused Boston Marathon bomber Dzhokhar Tsarnaev began, it was the first time many survivors saw him in person.

Tsarnaev reportedly walked into the courtroom with a swagger, wearing a dark suit with an open-neck shirt.

Many of the survivors and family members of the four victims looked at him and sized him up. He did not look back at them, but took a seat with his back facing them.

He reportedly seemed fidgety, twirling his fingers and drumming them on the table, and putting his hands in his pockets and taking them out. His hair was trimmed, but still long and he had facial hair.

The only people who will see Tsarnaev are the ones in the room for the trial, as cameras are not permitted in federal court.

Tsarnaev is being held at the Moakley Courthouse.
