Short answer: it stays longer than it would when a person is alive, but determining the amount and the source is difficult because of contamination and the fact that alcohol is a by-product of decomposition in most kinds of tissue.
Accurate measurement of blood alcohol in cadavers is difficult, and gives widely varying results depending on cause of death, trauma, and other factors. If it is obtained from venous blood immediately after death, it is fairly accurate.
In the case of cadavers, the preferred method is testing alcohol content of the vitreous humor (VH) in the eye. (Hey, you asked....) Although this seems to work well when gas chromatography analysis is used, a legally-accepted correlation between VH alcohol content and blood alcohol content v. time of death has yet to be established.
