A Kentucky judge whom authorities said was fatally shot by a sheriff last week was remembered Sunday as a pioneer who fought against opioid addiction and favored treatment over jail for low-level drug offenders.

Letcher County Sheriff Mickey Stines, accused of killing Mullins, once served as a bailiff in the judge’s courtroom.

District Judge Kevin Mullins was shot inside the Letcher County Courthouse. Kentucky State Auditor of Public Accounts Allison Ball confirmed Mullins was the shooting victim in a post on social media.
