The story behind Billy's coffin

When evangelist Billy Graham was laid to rest this week, his body lay in a simple plywood coffin built by a
convicted murderer, Richard Liggett, and two of his fellow inmates.

At the request of Billy Graham's son, the names of the three prisoners  are burnt into the side of his father's casket.

The Graham family has long been involved in gospel  work in the Louisiana State Penitentiary, the largest maximum security prison in the world.

Billy Graham preached to presidents and prime ministers, and millions of people across the globe, but he didn't forget some of his nation's most forgotten people: its prisoners.
