A downtown Atlanta hotel says it found no problems with the exit door of a walk-in freezer where a woman was found dead inside.

The Westin Peachtree Plaza said in a statement that it conducted repeated tests of the door and found that the door handle on the freezer "worked perfectly" after 61-year-old Carolyn Robinson was found dead inside. Investigators believe Robinson, a kitchen worker, spent about 13 hours inside the freezer before her body was found Tuesday morning.

Atlanta police Lt. Charles Hampton said after her death that police weren't certain whether the mechanism worked properly, adding that finding that out would be up to the U.S. Occupational Safety and Health Administration. The federal agency is still investigating.
