S18, E10: Two inebriated high-school girls, Kelly Daugherty (guest star Lisa Joyce) and Anne-Marie Liscomb (guest star Molly Ephraim), are agitated after their car is towed at a party. Liscomb walks off to make a phone call in an attempt to call a ride, and is found dead in a dumpster days later. After tracking down the cab driver that picked up Liscomb, new information leads the detectives to a drug-addicted prostitute with an affluent past, known as "Sugar" (guest star Maria Dizzia) and her partner Tito Cabassa (guest star Pedro Pascal). A war of words unfolds as the detectives pit the prostitute and pimp against each other to see who will talk first. When the case goes up for trial, ADA Connie Rubirosa (Alana De La Garza) appears to have an unrelenting admirer in the jury pool. Also Starring: Sam Waterston, S. Epatha Merkerson, and Linus Roache.
