Crossovers and Milestones
Crossover1.jpg
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."
