According to court documents, Hinderliter, 85, of Fort Smith, pleaded guilty to a felony Information charging unlawful distribution of a controlled substance namely, alprazolam. From approximately January 2016 and through November 8, 2018, Hinderliter was an owner and practitioner at Hinderliter Pain Clinic that operated as a pain management clinic in Barling, Arkansas.

As part of the plea, Hinderliter admitted that he prescribed opioids and benzodiazepines to more than 150 individuals, often not for a legitimate medical purpose and not in the usual course of professional practice.
