Saving Sammy

The parents of an autistic boy are gunned down in their car while on their way to get takeout. The 2003 case is reopened when Joseph informs Lilly that the boy, now in a state institution, blurts out a specific number whenever the parents are mentioned. It's soon learned the boy was in the car when the murders occurred, but he's unable to identify the killer. In a more personal matter, Ray tells Lilly he's leaving for California and wants her to come with him.
