'Chicago Fire'-'Chicago P.D.' crossover first look: Shay's killer targets Dawson

The upcoming Chicago Fire and Chicago P.D. crossover will be very dangerous for everyone as the teams get closer to tracking down arsonist Elliot Gish (Robert Knepper), who was responsible for Shay’s death. Though, it’s Dawson who should really be worried after she is specifically targeted by Gish in the trailer below. Will the teams be able to bring Gish to justice?

The crossover event kicks off Feb. 3 on NBC.
