WICHITA, Kan. (AP) — Competency questions have stalled the prosecution of a man charged with capital murder and rape in the death of a woman who was set on fire at a Wichita park.

The Wichita Eagle reports that the arraignment of 28-year-old Cornell McNeal has been on hold for over a year. He’s undergoing a second evaluation at a mental health facility in Larned after refusing to speak to his attorneys and the court.

McNeal is accused in a November 2014 attack that left Letitia “Tish” Davis with burns on more than half of her body and cuts on her head. The 36-year-old mother of four died about a week later.

Affidavits show a damaged cellphone and DNA evidence connected McNeal to the attack. Prosecutors are contemplating seeking the death penalty.
