A perfect town. An unthinkable crime. Can there ever be justice?

In the early-morning hours of July 23, 2007, in Cheshire, Conn., ex-convicts Steven Hayes and Joshua Komisarjevsky broke into the family home of William Petit, his wife, Jennifer, and their daughters, Michaela, 11, and Hayley, 17. Dr. Petit was beaten and tied to a pole in the basement. The three women were bound in their bedrooms while the men ransacked the house. The brutal ordeal continued throughout the morning, ending with rape, arson and a horrific triple homicide.
