Interesting. No date of birth or date of death?

The original article was from December of 2020 so one assumes she was alive then. The date of the obituary is in the link as August 10th of 2021.

By definition she died somewhere between these dates. All I did was Search "obituary Tiffany Dover Chattanooga, Tennessee". Google only gave results from twitter and fact checkers. I switched to Duck Duck Go and this was the first hit.
