Jennifer's sister Lisa and brother-in-law David continue to suffer feelings of guilt even after making every effort to ensure no one would drink and drive after their wedding. "We planned better than most would plan. We had a bus to take people back and forth from the hotel to the reception," David says. "We had a whole slew of rooms for people to stay in. We had limousines for parents and family, and that wasn't enough."

Lisa says she feels guilt about everything. "We had it on the Fourth of July weekend. If you look at the statistics, that's DWI season," she says. "Would this have happened if it wasn't on such a big night? Maybe not. Those are the decisions that ultimately killed my family.

"How do we start a life when your start is death?" Lisa asks. "It's your wedding day, and now they don't have their child."
