Summary: In the spring of 1993, two newspaper carriers driving down a rural road spotted what they thought was a doll but which turned out to be, in fact, a newborn baby's body. The coroner would determine that the baby had been born alive; but his origin was a mystery. The community called the baby Geauga's Child, after the name of the county; they made clothes for his funeral and paid for his burial. Despite dozens of leads and even a hidden camera placed at the cemetery in hopes that the child's mother would show up, no arrests were made for 25 years.
