Sean and his partner, Sergeant Whitey Powers, investigate the murder, while Jimmy conducts his own investigation using his neighborhood connections. Sean discovers that Katie apparently recognized her killer and that the gun used to kill her, a .38 Special revolver, was also used in a liquor store robbery in 1984 by "Just Ray" Harris, the father of Brendan. Harris has been missing since 1989, but Brendan claims he still sends his family $500 every month. Brendan also feigns ignorance about Ray's gun. Whitey suspects Dave who keeps changing the story about how his hand was injured. Dave continues to behave strangely, which upsets his wife to the point she leaves their home and tells Jimmy she suspects he might be involved in the murder.
