WICHITA, Kan. (AP) — A preliminary hearing has been delayed for a suspect in the death of a 100-year-old Wichita woman three weeks after she was allegedly raped.

The hearing was delayed Thursday after an attorney for 36-year-old Kasey Nesbitt asked to withdraw from the case.

The Wichita Eagle reports Sedgwick County District Judge David Dahl appointed a new attorney for Nesbitt and tentatively scheduled a preliminary hearing for June 15.

Nesbitt is charged with first-degree murder in the October 2014 death of Martha Schell. She died 21 days after she allegedly was assaulted.

He was originally charged with rape and aggravated burglary but after an autopsy report was released last month, prosecutors added the first-degree murder charge.

Nesbitt has pleaded not guilty to the rape and aggravated burglary charges.
