Jackie was an OC within the Postal Universe(specifically the Postal 2 Universe). She was the secondary protagonist
and was an aquaintance to the Postal 2 Dude in said universe.
A woman
At a young age, she developed a drug addiction(specifically cocaine). She lost contact with her family and became
homeless. A man took her in and promised to "give her what she wanted". She agreed, not thinking about what he wanted out
of her until it was too late. That man was referred to as "Daniel". The name refers to the brand of liquor "Jack Daniels",
prompting the man to call her Jackie. This may be a reference to how sex workers were often named after liquor.
