Hattiesburg fire chief David Webster is retiring after 27 years as a firefighter. The 54-year-old Webster has been fire chief since 2006. Webster tells the Hattiesburg American he plans to continue working in the realm of fire service, likely through training, writing and consulting. Webster says his age played a role in his decision and new municipal government term starting in July made the time right. His last official day is June 21. Assistant Chief Paul Presley will be interim fire chief. Webster says one of his biggest accomplishments is a memorandum of understanding between the department and AAA Ambulance Service.
