Nancy Heuring spent 20 years working with people with developmental disabilities for the Department of Human Services. Heuring toiled through her last decade of work while dealing with the effects of multiple sclerosis, friend Patricia Burns wrote in 1994 to then-Oklahoma County District Attorney Bob Macy. "She was always an inspiration to others because she didn’t allow her disability to limit her goals, aspirations or daily activities,” Burns wrote. Heuring, who had only limited use of her left hand, used a motorized wheelchair. "She was such a giving and caring person and always gave back, even in her condition,” nephew Kent Ferguson said. "She was an amazing person.” Heuring, who was widowed in 1991, had to make arrangements for her care because her family lived out of state, Burns wrote. Ferguson said he hopes Carie Walker and Dedra Wilhite, the two women convicted of killing his aunt, stay in prison as long as the law allows. "They both should serve their time, their full term,” he said. Walker was denied parole last month, while Wilhite could be released soon if Gov. Brad Henry agrees.
