A Kentucky sheriff who was accused of fatally shooting a district judge in his chambers two months ago was indicted for murder Thursday.

Prosecuting attorney Jackie Steele said after a grand jury returned the indictment that he couldn't comment on an alleged motive, although police previously said Shawn “Mickey” Stines — then-sheriff of Letcher County — and Judge Kevin Mullins had argued just before the Sept. 19 shooting, the Lexington Herald-Leader reported.

'Everything seemed fine between them. There was no clue that anything was wrong at all. You wouldn't have guessed there was the slightest problem.'

Judge Julia H. Adams received the indictment and set Stines’ arraignment for next Monday, the paper said.

Stines turned himself in after the shooting and was charged with first-degree murder, the New York Times reported, citing police. He retired as sheriff less than two weeks after the shooting.

Stines — who's accused of shooting Mullins eight times — pleaded not guilty to the murder charge.

The shooting was captured on surveillance video. You can view the surveillance clip here; it omits the actual shots being fired, and it's included in a larger video report about the shooting. Spectators cried out in the Morgan County courtroom as the video played during a hearing last month, WDKY-TV reported.

Kentucky State Police Detective Clayton Stamper testified that the full video of the shooting shows Stines using his own phone to make multiple calls, then using the judge’s phone to make a call, the Louisville Courier Journal reported, adding that the shooting followed.

Stamper testified that the calls were to Stines’ daughter, the Courier Journal noted, and he said the phone number of Stines' daughter had been saved in the judge's phone and was called before the shooting. Stamper also said Stines stood up from his chair in the judge’s office after looking at Mullins’ phone and shot him seconds later, the Herald-Leader said.

The shooting is particularly curious since Stines and Mullins reportedly had been decades-long friends.

What's more, the pair went to lunch at the Streetside Grill & Bar on Main Street just hours before the shooting, the Daily Mail reported. A restaurant employee told the outlet that Stines and Mullins ordered their usual lunch — both having chicken wings with salad.

"Everything seemed fine between them. There was no clue that anything was wrong at all," an employee said. "You wouldn't have guessed there was the slightest problem."

A woman who reportedly works for the Letcher County Sheriff’s Office also gave her phone to investigators for examination, WDKY said, adding that Stamper testified that she was one of Stines’ employees and believed she’d received text messages from Stines that noted what occurred at lunch and led to the shooting.

Under cross-examination, Stamper said that when Stines "was taken into custody, I was told by one of the other officers that were there that he made the comment, ‘They’re trying to kidnap my wife and kid,'" WDKY added.

More from the Herald-Leader:

The crime could be eligible for the death penalty if Stines is convicted because Mullins was a public official. Steele, who is prosecuting the case with Attorney General Russell Coleman’s office, said there had been no decision yet on whether to seek the death penalty against Stines if he is convicted. However, Stines’ attorney, Jeremy Bartley, has said that he does not think the murder is the appropriate charge in the case.

Bartley said at the Oct. 1 hearing that the evidence offered there pointed to the shooting as being an act of “extreme emotional disturbance” in reaction to something Stines had seen on Mullins’ phone.

There was no information at the hearing about what was on the phone. If a jury decided Stines acted out of extreme emotional disturbance, he couldn’t be convicted of murder, but rather first-degree manslaughter or a lesser crime. The death penalty would not be an option in that case.
