Was summoned once and selected once. I believe it's a duty as well and didn't make any special effort to get out of it, even though it meant a week off work without pay - and as a single mom, that was hard. It was a pretty gruesome case. Guy was released from jail where he'd served 8 months for car-jacking. On his way home from jail, carjacked someone else (and beat the hell out of her in the process) then went and cruised his hood. At about that time, a 16 y.o. girl was walking home from her job waiting tables at Waffle House, around 6pm, but it was full dark out. He grabbed her, raped her, killed her, put her body in the trunk of the jacked car, and spent the next two days showing her body to his buddies - none of whom reported it. News of the missing person investigation reached him a few days later so he took her body to an abandoned building in the projects and stashed her in a closet. Then he and a buddy used a pipe and bleach to try to remove evidence of the rape. He left her in the building for a week or so, then put her back in the trunk of his car and moved her. I can't remember to where, but that's where they found her body.
The testimony was gruesome, the guy sat there and stared at us jurors all day every day, no one testified on his behalf, and after four days of the trial it took us almost a full day to convict (there was an elderly black man who said he was tired of seeing young black men go to jail every time a white person was killed - we eventually convinced him). When we were released, the DA was waiting to speak to us and thanked everyone individually. When he got to me, he said, "I'm sorry you had to sit through all of that, I know it was difficult to see and hear, but I had to have you on this jury. You're the spitting image of the victim and I wanted to rattle him."
It was a difficult week seeing the photos, hearing the MEs testimony, the cops who found her, his buddies describing what he did, him staring at us all week, but it needed to be done. And if I hadn't, and 10 others that were selected hadn't, there could have been more like the old guy and he might have gotten off. We each have a responsibility.
