Investigators were "trying to get answers to what led up to the actual shooting," State Trooper Matt Gayheart said at an evening news conference.
The judge was shot multiple times after an argument with Stines, state police said.
Other people were in the building when the shooting occurred, but nobody else was in the judge's chambers, Gayheart said. Stines turned himself in to authorities at the scene, Gayheart said, adding that he believes there is surveillance video within the courthouse.

The Letcher County Courthouse is in Whitesburg, about 200 miles southeast of Louisville.
The small community was "shook" by the deadly violence, Gayheart said.
"We could use everybody's prayers. Say prayers for the family that they get through this difficult time," he said.
Relatives for Mullins and Stines were not reached for comment Thursday.
According to a Letcher County website, Mullins was a judge in the 47th Judicial District, overseeing juvenile matters, city and county ordinances, misdemeanors, traffic offenses, arraignments, felony probable cause hearings, claims involving $2,500 or less, civil cases involving $5,000 or less, voluntary and involuntary mental commitments and domestic violence cases.
The Kentucky Court of Justice, the state court system, said it is working with the state police.
"While the investigation is ongoing, we are committed to providing assistance in any way that we can," the court said in a statement. "Our deepest sympathies go out to all those impacted by this tragic event, and our thoughts and prayers are with the community during this challenging time."
Attorney General Russell Coleman promised a full investigation.
"Following the deadly shooting in Letcher County, our Office will collaborate with Commonwealth’s Attorney for the 27th Judicial Circuit Jackie Steele as special prosecutors in this case. We will fully investigate and pursue justice," Coleman said on X.
