A competency hearing for Louis Carl Guenther, 68, of Checotah, has been set for 9 a.m., Wednesday, Aug. 27.
Guenther is accused of beating and stabbing to death his sister, blues musician Selby Minner, 75, on June 9 at her nightclub/residence in Rentiesville.
Guenther has had several competency hearings since then.
Guenther made his initial appearance in court on Friday, June 13. Associate District Judge Brendon Bridges entered a not guilty plea on behalf of Guenther and ordered him to return to court on July 23 for a competency hearing. He is being held without bond.
According to a Probable Cause Affidavit filed by Kevin Branscum, Investigator for the District Attorney’s Office District 25, Guenther confessed to making the decision on June 9 to kill his sister, then beat her with a hammer and then stabbed her to death before walking across the street from her residence to sit and wait at the Battle of Honey Springs historic site.
