A lesson to be learned:

It was in the tiny community that a man stormed into a one-room schoolhouse and shot 10 young girls, killing five. He then killed himself. That old school has since been demolished. The new school was closed on the one-year anniversary and families met privately in prayer.

Since the tragedy, people around the world have been inspired by the way the Amish expressed forgiveness toward the killer and his family.

Charles Roberts wasn't Amish, but Amish families knew him as the milk truck driver who made deliveries. Last month, it was announced that the Amish community had donated money to the killer's widow and her three young children.

It was one more gesture of forgiveness, gestures that began soon after the shooting.

Donald Kraybill, is a sociologist at nearby Elizabethtown College and co-author of Amish Grace: How Forgiveness Transcended Tragedy.

"I think the most powerful demonstration of the depth of Amish forgiveness was when members of the Amish community went to the killer's burial service at the cemetery," Kraybill says. "Several families, Amish families who had buried their own daughters just the day before were in attendance and they hugged the widow, and hugged other members of the killer's family."
