The murder trial of a Dunbar woman accused in a bizarre, deadly stabbing and sex crime case has been pushed back. The trial for Courtney Wallace that was set for Monday, Jan. 27, will now be March 23. Dr. David Clayman said Wallace needs another interview and more time to complete the psychiatric evaluation. Wallace was accused of stabbing and killing Cheri Simpson at a home in the 2700 block of Furlong Ave.
