I would like to offer my sincere condolences on the passing of your aunt and offer my apologies at the lack of communication and assistance on such an important day.  We have discussed this with the staff member who is deeply upset by her decision to not stay with your aunt.  The codes for the gates are available to staff and the one that had been secured was not a fire escape.  I am sorry that this caused your further distress.  I hope that by speaking with me you are reassured lessons have been learned.
