A new federal court filing shows that investigators believe the convicted murderer and rapist known as the “Devil in the Ozarks” has likely fled Arkansas after escaping prison last month.

A former small-town police chief in Arkansas escaped from prison Sunday while serving decades-long sentences for murder and rape and is still on the loose, officials said Wednesday.

Grant Hardin's escape from the North Central Unit and the ensuing manhunt for the fugitive have placed a national spotlight on Arkansas, but it is far from the first attention-grabbing breakout in Arkansas history.
