Sudden infant death syndrome, no signs of abuse, no cause doctors could find. The community grieved with her. She was seen as a mother cursed by fate. But investigators eventually noticed something chilling. Every death happened while the children were alone with her. Not one survived past age five. In 1985, after her ninth child, Tammy Lynn, was found dead, police stepped in. Autopsies showed signs of smothering. And when questioned, Mary Beth confessed she had murdered them all. The deadliest mother in American history. If you like these stories, drop a comment, click on the like, and subscribe for
