For nearly four decades, anyone driving down Route 16 near Fayetteville, West Virginia, could see a billboard bearing the grainy images of five children, all dark-haired and solemn-eyed, their names and ages—Maurice, 14; Martha 12; Louis, 9; Jennie, 8; Betty, 5—stenciled beneath, along with speculation about what happened to them. Fayetteville was and is a small town, with a main street that doesn’t run longer than a hundred yards, and rumors always played a larger role in the case than evidence; no one even agreed on whether the children were dead or alive.
