Law & Order: Trial by Jury S01E12 - Boys Will Be Boys

Prosecutors Kibre and Gaffney are stymied when a young man confesses to killing a transvestite upon discovering that the "she" was a "he" -- just before the suspect's controlling father also admits that he pummeled the victim to death in self-defense. Besides being whipsawed between two divergent confessions, the suspicious assistant D.A.s can't seem to turn one against the other, prompting a determined Kibre to reach into her legal bag of tricks to force the issue in court.
