The Crewe Murderer
The Crewe murders is a pretty good one. A farming couple was murdered and their bodies were dumped in a river. After they were missing for a week, their home was searched and their still-living baby daughter was found there.
The wife’s father was convicted of the crime, but later released when it was discovered that the detective inspectors in charge of investigating had falsified evidence to implicate him. The actual murderer has never been identified.
What makes it interesting is that doctors believe that during the week her parents were at the bottom of the river weighted down with car parts, someone was regularly feeding the baby.
