Weeks after Kentucky's Letcher County and District Judge Kevin Mullins was found dead in his chambers and Letcher County Sheriff Shawn M. Stine was arrested, more details about what led to the shocking incident have been revealed.

Shocking new video has surfaced capturing the chilling moment a Kentucky sheriff pointed his gun at a judge’s head before allegedly shooting him dead. The newly released surveillance footage shows Letcher County Sheriff Shawn Stines with District Judge Kevin Mullins in his chambers having what appeared to be a heated exchange before the sheriff pulled out his gun and pointed it at the jurist’s head.

The last time he was in a courthouse, he fatally shot a judge, investigators say. On Tuesday, a former Kentucky sheriff will be in a different courthouse to hear the evidence against him.
