In late July, the Louisiana attorney general ordered the arrests of a doctor and two nurses in New Orleans, accusing them of administering a lethal combination of sedatives and painkillers to four critical care patients at Memorial Medical Center in the days following Hurricane Katrina. The deaths occurred under nightmarish conditions of heat, power loss, and flooding, in which many patients at the hospital had already died.
