Hunter's father wasn't such a clean guy in his early days. He put his family in danger a few times during his years in the streets. When Hunter was only two her mother was murdered by a mobster. From then on out, her sister and her father were the only people in her life. Her father eventually put his old ways behind him, for the sake of his children. Even with his past behind him, her father knew that it wasn't all over.
A few years later, Hunter goes to visit her father one day and finds him dead in his home. The death of her father was no accident, someone had targeted him and he knew someone was coming after him. He had left behind everything she would need to find the ones responsible. Hunter was determined to find his killer, no matter how long it took her and how many people she had to put down to get to what she wanted-- she would find him and nothing would stop her.
