NEW ORLEANS (AP) - A grand jury in Louisiana has declined to indict a surgeon accused of killing four seriously ill patients in the aftermath of Hurricane Katrina.
Doctor Anna Pou and two nurses were arrested last summer after an investigation by the state's attorney general concluded they killed four people with a "lethal cocktail" at a medical center during the chaotic conditions that followed the August 2005 storm.
At least 34 people died at the hospital, many from dehydration during the four-day wait for rescuers to evacuate them.
The four Pou was accused of murdering ranged in age from 61 to 90 years old. The attorney general says the four would have survived if they hadn't been given central nervous system depressants.
