And when she returned to her job as a teacher, about a month after the trial ended, she sometimes saw a flashback of the Petit girls' picture in her fifth-grade classroom.
"Just thinking about what it was like right before they set the fire. ... This happens periodically, I see this image of the girls being burned," she said. "Something that I see will trigger the memory of the trial and the pictures."
And when it comes to a tragic case such as this or Casey Anthony's, with a lengthy trial, it's important to seek help when you need it afterward, Kaslow said.
"I think that these jurors need to be very aware that when you get off a case like this, you may need some counseling. This is going to bring up different things for different people, depending on your life story," she said.
When the Hayes trial was over, jurors had a debriefing with counselors. Some sought counseling afterward, Calzetta said. And some, including Calzetta and Keim, have remained friends.
"When we get together, we don't need to talk about it. We all just understand," she said.
The trial of Joshua Komisarjevsky, the other man accused of participating in the murders of Hawke-Petit and her children, is scheduled for September. The lead-up to it brings back more memories for Calzetta, but she still plans to attend at least part of the trial because she feels that she needs to hear that side of the story.
To this day, Calzetta keeps a photo of Hawke-Petit and the two daughters, Hayley, 17, and Michaela, 11, on her desk. She hasn't been able to go to their memorial garden, which is where the house they died in used to stand, but she hopes to go this summer with flowers.
"It's sort of like opening a wound a little. Your spirit goes into a place that you were before," she said. "There's a lot of pain there."
