The surviving suspect in the Boston Marathon bombing, Dzhokhar Tsarnaev, has pleaded not guilty on 30 counts, including the murders of four people. In his first public appearance since the violent standoff after the bombing, Tsarnaev faced a courtroom packed with survivors and victims’ relatives. After the hearing, some of those who came said it was difficult to see Tsarnaev in person.

Mildred Valverde: “Just his presence being there after all the destruction he caused and all the hurt he caused everyone, just to be in the same room with him was bothersome. I’m heading home now.”

Liz Norden: “I don’t know. I actually felt sick to my stomach. It’s very emotional for me. So, you know, I actually felt — I’m angry, but I actually feel really — I don’t know. I feel sorry for everybody.”

Tsarnaev could face the death penalty if convicted.
