Pottawatomie County Sheriff Deputy Travis Palmer said Davis and St. Clair were drinking beer on the night of December 21, 2014 at the older man's residence when St. Clair began speaking ill about his wife, who is Davis' mother.
Davis told investigators the two fought because St. Clair was calling him and his mother worthless. St. Clair had filed for divorce in September, reports News Ok.
Investigators said St. Clair's elastic waistband was stretched over his head and that it left ligature marks around his neck.
Blood splatter was also found in the kitchen, the living room and on the living room ceiling.
Davis was being held in Pottawatomie County without bond. His lawyer was not immediately available for comment.
