Claude Edward Dalrymple was sentenced Thursday to 18 years in prison for the beating death of a 73-year-old Lexington man.
On June 19, Dalrymple, 44, pleaded guilty but mentally ill to first-degree manslaughter for killing Dale Irons. Irons had moved in with Dalrymple three days before he died Aug. 31, 2013.
Lexington police detective David Sadler testified in September 2013 that Dalrymple told police Irons had insulted him.
Dalrymple will have no chance of parole, but he will get mental health treatment while in prison.

To determine whether Dalrymple was mentally fit for trial, Fayette Circuit Judge James Ishmael ordered that he be evaluated at the Kentucky Correctional Psychiatric Center, according to court documents.
Doctors there requested that Dalrymple stay an additional 30 days because he was "still psychotic but improving," according to court documents.
He eventually was found competent to stand trial, but Dalrymple's plea deal reduced the murder charge to first-degree manslaughter, according to court documents.
Irons and Dalrymple had been living in a two-bedroom apartment with Jeff Crockett as part of a program that houses military veterans with substance-abuse problems, Sadler testified during the preliminary hearing.
Crockett, who found Dalrymple beating Irons, tried to call 911 but was stopped by Dalrymple, Sadler testified. Dalrymple took Crockett's phone from him and threatened a similar beating if Crockett told anyone.
Neighbors eventually called police; when officers arrived, they found a bloodied Irons on the floor next to Dalrymple.
Irons was alive when he was taken to University of Kentucky Chandler Hospital. He died of blunt-force injuries.
