Gina (surname unknown) is the girlfriend of Angel Rivera, a gangster in prison hired by Sunny Qadri to murder two mercenaries she used to kill Page Ferguson, her boss in the district attorney's office and professional friend and the only witness to Qadri stealing drug money.
When Rivera was convinced he could get a legal deal to absolve him of his legal scrutiny, he had his girlfriend Gina contact one of his hitmen, resulting in the two mercenaries being shot dead in their apartment. Gina was found out and arrested, brought to the prison Rivera was in.
With an ultimatum, Rivera was presented Gina being absolved of charged if he ratted out his accomplice, offering the deal because she was pregnant and due to give birth soon. When Rivera gave up Qadri, his charges were increased and Gina walked. (SVU: "Dirty")
