S10, E15: Pediatrician Gilbert Keppler (Guest Star Lawrence Arancio) is found guilty of sexually assaulting four of his male patients. Soon after his trial, his attorney, Lionel Granger (Guest Star David Thornton), informs the detectives that Keppler will be suing the NYPD and the Denslow Medical Center on the grounds that they knew he was sexually abusing patients long before they took any action to stop him. Detectives Elliot Stabler (Christopher Meloni) and Olivia Benson (Mariska Hargitay) decide to go directly to Keppler for questioning only to find him murdered in his apartment. To the detectives surprise, ADA Alexandra Cabot (Guest Star Stephanie March) shows up at the crime scene, after three years in the witness protection program.

Also starring: Richard Belzer (Detective John Munch), Dann Florek (Captain Donald Cragen), Ice-T (Detective Odafin Tutuola), Michaela McManus (A.D.A Kim Greylek), Tamara Tunie (Dr. Melinda Warner), and B.D. Wong (Dr. George Huang).
