Dear Ms. Lester,
Thank you for posting your request on History Hub!
We suggest that you contact the Georgia Department of Public Health to request a search for the death certificate of Alex Lester; and the Coroner's Office – Rockdale County, Georgia to obtain the coroner’s report of his death on February 11, 1983.
In addition, the FamilySearch Research wiki for Georgia Vital Records may be useful.
We hope this is helpful. Best of luck with your family research!
