"Officers returned to Loud’s home to further question her. They noticed the unclean condition of the home. Loud later told officers she had not cleaned in 10 years, according to the police report.

Asked if she had been drinking, Loud said she stopped off after work and drank a few beers before coming home to watch baseball. She said she might have had some hard lemonade at home."

There's no indication, at least in this article, that she drove at all. She simply said she came home. Those sorts of technicalities are huge in courts. To your point, you're absolutely right in that alcohol and its resulting effects take time, so any testing done (especially when they came back to her house a second time) should have absolutely no standing.
