S19, E7: Detective Lupo (Jeremy Sisto) and Detective Bernard (Anthony Anderson) are called to a crime scene where Nancy Hartwig (guest star Leah Curney) has been found murdered. They find out her husband insisted the family live environmentally friendly to avoid leaving a heavy carbon footprint. However, Nancy's support of her husband is soon called into question when the detectives discover that she used her car to chauffeur her sister and had drinks at a bar one evening, which her husband wouldn't allow. The victim's missing car turns up with a dead passenger and drugs inside, sending the case in a completely different direction that leaves the detectives scrambling to piece everything together. During the trial, ADA Michael Cutter (Linus Roache) also begins to suspect an old friend, Judge Reynolds' (guest star Ned Beatty) clerk Carly (guest star Sherry Stringfield), and even the judge himself of obstructing justice, creating even more turmoil in the case. Also starring: Sam Waterston, S. Epatha Merkerson and Alana De La Garza.
