Jeannie Kerns is a former prostitute with a history with spree killer Craig Rasmussen. She had been working the job for 25 years and racked up a long criminal record. One of her arrests was carried out by Detective Olivia Benson, who was a beat cop during that time.
After assisting the Manhattan Special Victims Unit in the manhunt for Rasmussen, which resulted in his death, she was convinced to quit her job through an intervention by SVU and her family. (SVU: "Dreams Deferred")
