A defendant who received two life sentences in the 1986 double murder of a local couple appeared in a Pottawatomie County courtroom Monday to challenge that sentence and ask for post conviction relief, but that motion was denied.

A defendant who received two life sentences in the 1986 double murder of a local couple appeared in a Pottawatomie County courtroom Monday to challenge that sentence and ask for post conviction relief, but that motion was denied.

Ronald D. Cummins, 52, has spent the last 30 years incarcerated for the 1986 killings of Floyd "Buddy" Kinnamon, 46, and his wife, Rhonda Sue Kinnamon, 32.

Cummins was 22 when he pleaded guilty to two counts of first-degree murder and was sentenced to life in prison after a negotiated plea deal. Co-defendant Derek Lee Tibbs, who was 25 back in 1986, is currently serving two sentences of life without the possibility of parole and a life sentence for first-degree rape.

Cummins, who appeared in handcuffs and shackles, represented himself during the morning hearing before Associate District Judge Dawson Engle in hopes of getting a commuted sentence.

District Attorney Richard Smothermon argued that all issues raised Monday were inapplicable for post conviction relief and said what Cummins asked for was not in the court's authority. He noted that time credit or when someone is up for parole is handled by the Department of Corrections; a life sentence is typically 45 years.

Judge Engle reviewed the case file before making his decision.

“It's not within my power to tell DOC how to compute their credit or policy in determining what a life sentence is,” the judge said before he denied the motion for post conviction relief.

Cummins will remain in the Pottawatomie County jail until he is transferred back to a state prison. According to DOC inmate records, Cummins began serving his sentence in January 1987 and he is up for a parole hearing in September 2019.

According to news archives, the couple owned the Liberty Club in Shawnee. Cummins and Tibbs were allegedly burglarizing the couple's residence when the couple came home.
