Hanson was a captain in the Atlanta Police Department. His second in command was Lt. Dawn Lerner who, sometime before the outbreak, presented her an award for her work with the Atlanta Police Department.
Hanson was mentioned by Dr. Steven Edwards as the commanding officer who was tasked with evacuating Grady Memorial Hospital with Dawn Lerner and other Atlanta Police Department officers.
