Laura Shrub
Laura Shrub, in 1986, is the wife of Congressman Alex Shrub. However she has moved from Vice City to Alabama, and in the meantime her husband is treasoning her with a porn star, Candy Suxxx.
On the boxart for Grand Theft Auto: Vice City Stories, there is a lady that looks similar to Laura Shrub, but younger, leaning against an Infernus. There is no way to confirm or deny this.
