Officials are scouring Arkansas’ rugged Ozark Mountains for a former police chief and convicted killer who escaped from prison over the weekend.

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

Grant Hardin, the former police chief in the small town of Gateway near the Arkansas-Missouri border, was serving lengthy sentences for murder and rape and became known as the “Devil in the Ozarks.”
