This is likely false. Toxicological tests revealed no unusual substances in the victim's blood, but at last report the case remains open in spite of the fact that police apparently have no evidence or leads to follow. Though the details have metamorphosed over time, the legend showing up in inboxes today is directly descended from rumors based on early news reports about that very incident.

The victim told Investigators the incident occurred at the Amsouth Bank at 2326 Saint Stephens Road.

She sniffed it once, detected nothing odd, then sniffed it again and lost consciousness. Within days, the story of her parking lot misadventure was all over the Internet.
