- "In the criminal justice system some killers are so depraved that it takes multiple police agencies to bring them to justice. This is one of those investigations." - Steve Zirnkilton
The Chicago Franchise shows have been known to feature characters from their sister series on nearly a weekly basis, even including multi-episode arcs and romances between characters. Additionally, both Chicago Fire and Chicago P.D. crossed over with Law & Order: Special Victims Unit. "The crossovers are incredible ratings engines for us," said Dick Wolf. "What we can't do is have them become commonplace."
