LAWRENCE, Kan. (AP) — The defense has rested in the first-degree murder trial of a Kansas health care worker accused of killing a client with cerebral palsy.

The Lawrence Journal-World reports that closing arguments are planned for Wednesday in the case of 49-year-old Ronald Eugene Heskett.

The Eudora man responded Tuesday to prosecution claims that he killed 65-year-old Vance Moulton for financial reasons. The defense has argued the September 2014 killing was an assisted suicide.

Heskett says the reason $13,000 was missing after Moulton’s death was because the men were partnering in a money-making venture. Heskett said they invested in a 1972 Chevelle to fix up and sell for a profit. The goal was to help raise money for a wheelchair-accessible van.

Heskett says they didn’t tell anyone else about the agreement.
