A candlelight vigil is scheduled for tonight to remember Bonny Wallace, a researcher at the University of Arkansas for Medical Sciences who was shot to death early Saturday. The vigil will be at eight tonight in front of her Little Rock home on Arch Street. Yesterday 42-year-old Leslie Ann Myers of Little Rock pleaded innocent to charges of capital murder and attempted capital murder at an arraignment. The case is to be heard in Pulaski County Circuit Court. Police say Myers shot Bonny Wallace in the back at Wallace`s home after a dispute over 12 hundred dollars that Myers claimed Wallace owed her. Myers, who once rented a home from Wallace, also is accused of trying to kill Wallace`s husband, Paul, when he went to help his wife. Bonny Wallace worked at the medical school for 36 years and is credited with helping to pioneer the treatment of patients at the Arkansas Children`s Hospital burn center.
