Wichita ? A southern Kansas man has pleaded not guilty to charges that he sexually attacked a mother of four before fatally setting her on fire.

KWCH-TV reports that an attorney for 28-year-old Cornell McNeal, of Wichita, entered the pleas Friday on McNeal’s behalf during a Sedgwick County arraignment.

He’s charged with capital murder in the November 2014 death of 36-year-old Letitia “Tish” Davis. She was found at Fairmount Park near Wichita State University by a neighbor who heard her screaming and discovered her on fire. Davis sustained burns on more than half of her body and died eight days later.

A judge on Wednesday found McNeal mentally competent to stand trial.
