Patty is first introduced in the season nine finale, where her father, Randy North is fighting for custody for her and her brother, Austin. Randy had assisted a known felon, Jack Toller, and had lost custody of his kids as a result. Austin and Patty were placed in foster care and were separated which drove Randy over the edge and forced him to try and kill Horatio and Natalia.
Randy was incarcerated after being tricked by Austin into meeting him where Horatio and his team found and arrested him for attempted murder.
Patty and Austin were reunited at the end of the episode where they were both sent to a foster care place that was ready to take the both of them.
In the series finale Calleigh had adopted both Austin and Patty with a little help from Eric Delko, who had put in a good word for her.
