Some in the audience didn't testify but said they felt it was important to attend.
Trish Keil and her twin sister, Helen Malyszka, two music teachers in Sandy Hook who knew many of the slain children, said they believe the tragedy will lead to change and won't be forgotten. Both support more gun control measures.
"I think it happened in Newtown for a reason and I think there is going to be major change because Newtown will not stand by and let this go," Keil said. "This is just, it's too horrific. When it's starting to affect our children, something has to be done and it's going to change."
