That does remind me though a Seattle area serial killer who targeted Native American women. He'd tie them up, and the force them to drink vast amounts of alcohol. When autopsies were done, the women were found with far higher BACs than are ever usually found, and it was theorized by medical examiners for a while that they'd been drinking so heavily for so long that they were able to function enough with ore alcohol in their blood, and keep drinking and raising that level even more.
That all changed when a white woman who hardly ever even touched alcohol in her life became his victim, and her reported history by her mother and friends flew in the face of the idea of being frequently drunk.
Basically, before that change, you could be this very same serial killer, and now you can't!
