The motive behind the shooting remains unclear, however Stines' attorneys indicated in court filings in March that they intend to launch an insanity defense.
Defense attorney Jeremy Bartley issued a legal filing saying his client's state of mind at the time of the shooting would be key to his upcoming trial.
He said the case will hinge on testimony that Stines gave at a deposition days before the September 2024 shooting. That saw the sheriff answer questions about one of his deputies allegedly sexually assaulting jail inmates.
An accuser in that case claimed that she was forced by a deputy sheriff to have sex in Mullins' chambers for six months in exchange for staying out of jail.
Bartley said Stines feared that backlash from his deposition testimony caused him to fear that his or his family's lives were in danger.
The attorney said Stines' 'mental health' was affected by the perceived threat.
'Ultimately, he was in fear for the safety of his wife and his daughter, and I think what you see there is the result of that,' the defense attorney said.
