S13, E23: A cop reporting to the scene of a dead jogger, Andy Corvo (Tim Gallin), who had a fatal heart attack, discovers the body of a woman, Anna Briseno, who is shot dead in Central Park. When Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) question her husband Rafael (Carlos Leone), he is grief stricken. He said he was at work the night it happened, but it turns out he left work early and had a drink. The Detectives suspect he could be the one who killed her. They find Rafael drunk and he points the finger at his brother, Renaldo (Otto Sanchez). In fact, Anna was really Marcella Celaya (based on a search of her social security number) and when they find Renaldo, who has just been released from prison, he says he can't be tried for her murder because he was accused of killing Marcella ten years ago. But the case was botched and even though he was convicted, obviously he wasn't guilty and based on double jeopardy rules; he can't be tried for the same crime twice.
