The Kentucky sheriff is seen in footage shooting the judge in a shocking preliminary hearing

During a court hearing for the ex-sheriff accused of murder, a shocking video was played showing the murder of a Kentucky judge in his chambers.

The short video clip was presented by prosecutors during the preliminary hearing for Letcher County Sheriff Shawn “Mickey” Stines, showing the shocking moments he allegedly opened fire on 54-year-old District Judge Kevin Mullins on Sept. 19.

The audio-free video showed a man identified by police as Stines pulling out a gun and shooting at the judge as he sat at his desk. The man walked around the desk, pointed the gun at the judge – who had fallen to the floor – and fired again.

The emotions of each person in the courtroom were palpable, with some moaning and crying audible.

Mullins died of multiple gunshot wounds, Kentucky State Police Detective Clayton Stamper testified Tuesday.

Stines pleaded not guilty to first-degree murder at his arraignment last week and is being held in another Kentucky county.

Stamper said Stines and Mullins had a friendly lunch with a group before the shooting and no witness noticed signs of anger in their conversation.

“I was told that the judge made a statement to Mickey: ‘Do we have to meet privately in my chambers?'” Stamper said, adding that he didn’t know what it was about.

Stamper said while he didn’t know of a previous relationship between the two, he said he had “heard things” about a lawsuit involving the sheriff’s office.

Stines was deposed in a lawsuit brought by two women, one of whom alleged that a deputy sheriff forced her to have sex in Mullins’ chambers for six months in exchange for her not going to prison.

The lawsuit accused the current sheriff of “deliberate indifference by failing to adequately train and supervise the deputy.”

A handful of people were in a room next to Mullins’ chambers when the shots rang out. Stines was in custody when he arrived at the courthouse, Stamper said.

Stamper said Stines was “mostly calm” when he arrived at the scene. “He basically just said, ‘Treat me fairly,'” Stamper said.

At the end of the hearing, Judge Rupert Wilhoit III concluded that there was probable cause to believe that Stines committed the crime and allowed a grand jury to decide whether to indict Stines.

If convicted of first-degree murder, Stines could face the death penalty.
