Two former prosecutors say that the insanity defense planned by the defense attorney representing former Letcher County, Kentucky, Sheriff Shawn “Mickey” Stines will not hold up.

Stines is accused of shooting and killing District Judge Kevin Mullins in the judge’s chambers inside the Letcher County Courthouse on Sept. 19, 2024, in an attack that was captured on surveillance video.

“It’s very rare in most states, including Kentucky, the insanity defense and similar mental health defenses rarely work, because if the person knows right from wrong at the time they committed some criminal act, then any mental health issues are, I guess, secondary,” Phil Holloway, a former prosecutor and legal analyst based in Georgia, told Fox News Digital. “If they know right from wrong, they can still be convicted even if they have a mental health issue.”

Bartley declined to comment for this story but previously told Fox News Digital, “I think one of the big things is that my client felt there had been pressure placed on him not to say too much during the deposition, and not to talk about things that happened within the courthouse, particularly in the judge’s chambers.”

Bartley said that threats against Stines’ family caused the paranoia to reach a fever pitch. 

“On the day that this [shooting] happened, my client had attempted multiple times to contact his wife and daughter, and he firmly believed that they were in danger,” Bartley said. “He believed that they were in danger because of what he knew to have happened within the courthouse. And there was pressure, and there were threats made to him to sort of keep him in line, to keep them from saying more than these folks wanted him to say.”
