S18, E5: When a Caucasian teenage boy and young African American girl are found dead near a neighborhood playground, Detectives Cyrus Lupo (Jeremy Sisto) and Ed Green (Jesse L. Martin) have trouble getting witnesses to talk after realizing the boy was targeted and the girl was killed accidentally. Two brothers and friends of the murdered boy, Andy (guest star Jeremy Allen White) and Josh Steel (guest star Miles Chandler), lead the detectives to a local kid Will Manning (guest star Tristan Wilds). Ultimately, it's Will's father Ray Manning (guest star Kevin Carroll) who admits to being the shooter. Ray's defense is that he feared for his son's life when he saw three boys chasing Will with baseball bats. This new information leads the detectives to suspect the Steel brothers and their overly aggressive mother, Gretchen (guest star Ally Walker). With racial tensions high in the community, the DA's office must decide how to charge and prosecute the case. Also starring: Sam Waterston, S. Epatha Merkerson, Linus Roache, and Alana De La Garza.
