Roger Hollister died Wednesday at the prison.
Jeremy Barclay, spokesman for the Kansas Department of Corrections, said the prison could not confirm reports that Hollister died of natural causes. But, Barclay says they have no reason to doubt those reports.
Hollister was serving a life sentence without parole for the first-degree murder of Patricia Kimmi of rural Horton. She disappeared in November 2009, and her remains weren’t found until May 2010. Hollister was convicted of capital murder in Atchison County in 2011.
