S19, E6: Detectives Lupo (Jeremy Sisto) and Bernard's (Anthony Anderson) search for "Sweetie Ness'" killer leads them to Lauren Claiborne (Taylor Gildersleeve), part of the entourage at the club where "Sweetie Ness" was last seen alive. The Detectives talk to Janice Dunlap (Guest Star Heather Matarazzo), a stalker who had sent "Sweetie" poems and had followed him that night, and Kate Tenny (Guest Star Vivica A. Fox), "Sweetie's" agent, who has her own motives. Seeking the identity of a blond man forces Lupo and Bernard to dig deeper into the victim's past and the possibility that "Sweetie Ness" was an imposter killed by the real "Sweetie Ness." With a defense witness willing to perjure herself to protect the prime suspect and a web of lies and deceit to untangle, A.D.A.'s Michael Cutter (Linus Roache) and Connie Rubirosa (Alana De La Garza) face one of their toughest challenges in bringing the real killer to justice. Also stars S. Epatha Merkerson and Sam Waterston.
