NEW ORLEANS, Louisiana (CNN) -- Three days after Hurricane Katrina flooded New Orleans, staff members at the city's Memorial Medical Center had repeated discussions about euthanizing patients they thought might not survive the ordeal, according to a doctor and nurse manager who were in the hospital at the time.
The Louisiana attorney general's office is investigating allegations that mercy killings occurred and has requested that autopsies be performed on all 45 bodies taken from the hospital after the storm.
Orleans Parish coroner Frank Minyard said investigators have told him they think euthanasia may have been committed.
"They thought someone was going around injecting people with some sort of lethal medication," Minyard said.
Dr. Bryant King, who was working at Memorial when conditions were at their worst, told CNN that while he did not witness any acts of euthanasia, "most people know something happened that shouldn't have happened."
