SEASON 4, EPISODE 414 - When a wealthy white teen and a struggling black teen from very different towns were murdered at the same exact time of day in 2002, no one made a connection. But now, Miller, who was an undercover cop at the time, realizes that the killings may be related, and she persuades Rush to reopen the cases. The black boy may have gotten himself into a turf war with drug dealers, and the white girl is initially believed to have been taking methamphetamines in order to continue being an overachiever. The tragic truth about how these two young people were connected, however, is much more shocking. Songs by multiple Grammy Award-winning band U2 are featured throughout the episode.
