Reality, it turns out, bears very little resemblance to "CSI."

My colleagues and I surveyed the nation's 69 busiest coroner and medical examiner offices. More than 1 in 5 of the physicians working in these morgues — including the chief medical examiner of Washington, D.C. — were not board certified in forensic pathology, the branch of medicine focused on the mechanics of death. Experts say such certification ensures that doctors have at least a basic grasp of the science, and should be a requirement for anyone performing autopsies in a possible homicide case.
