LAWRENCE, Kan. (AP) — Court records say a Lawrence health care attendant who is charged in the killing of man with cerebral palsy told authorities the victim wanted to die.

Forty-eight-year-old Ronald Eugene Heskett, of Eudora, is charged with first-degree murder in the asphyxiation death of Vance Moulton. The 65-year-old had a towel around his head when he was found dead in September.

The newly released affidavit says Heskett told investigators that Moulton repeatedly begged to be killed. The Lawrence Journal-World reports that Heskett said he gave in after Moulton said “he just wanted to walk with his mother again.”

Heskett says he twisted a towel around Moulton’s neck and told him to lay on it.

Defense attorney Mike Warner said he didn’t want to comment until he finished reviewing the police investigation.
