Segment 4 - A profile of the Darrington Prison Unit's seminary program which helps turn hardened criminals into pastors. Those inmates are then moved to other prison units to spread the gospel. The Darrington seminary program began 6 years ago. It costs about $250,000 a year to operate and is paid for through donations to the non-profit "Heart of Texas Foundation," which was started by the father of a crime victim. Similar prison seminaries are currently in place in more than a dozen other states.
