Season 2009 - Episode 10 - Aired Jun 12, 2009
In most places death has no schedule, but in Huntsville, Texas, an average of 16 people per year are scheduled to be executed by lethal injection. Inside Death Row interviews three inmates as their dates of execution draw near, and follows the stories of their families and loved ones as they deal with death firsthand. This story is not one of guilt or innocence; it is about how the State of Texas carries out the death penalty as well as the men and women whom, by choice or circumstance, become players in the act of executing another human being. Lastly, it explores how the residents of Huntsville feel towards living in a town that is ground zero for capital punishment in the United States.
