A state task force headed by the Oklahoma State Bureau of Investigation has ordered DNA testing for two death row inmates, John Hooker and Michael Hooper. The task force is investigating cases that involved Police Chemist Joyce Gilchrist, who was involved with both men's cases. Although Gilchrist's work is the primary focus of the task force's examination, the Oklahoma City Police Department has asked the task force to review as many as 10 additional cases handled by another former police chemist, Janice Davis. The investigation of Gilchrist has shed light on other cases, including some handled by OSBI itself. The agency is currently reviewing the case against Albert Wesley Brown. At Brown's trial, a former OSBI chemist testified that hairs found at the scene belonged to Mr. Brown, but recent DNA tests proved otherwise.
