The "One Chicago" shows seem to find pleasure in torturing its main cast members and running their lives through the wringer. And one of the easiest ways for the writers to bring pain into their lives is to kill off a beloved family member, whether it be a parent or a partner. In the case of "Chicago P.D." patrol officer Sean Roman, though, the show's target was his sister Sarah, who oddly enough never appears in the series. Because in the episode "Burden of Truth," a crossover event that ties in with "Chicago Fire," Sean receives a frantic call from his sister and returns to the Windy City after a lengthy absence to discover her dead body.
Sarah doesn't hang in there long enough to say goodbye to her brother. But in a stunning twist, Sarah's drug dealer and boyfriend Logan is found murdered, frozen in the icy snow. To make matters worse, Officer Burgess realizes that Sean is the man responsible — an apparent revenge killing for the death of his sister. And while Burgess and Voight consider having him charged in the killing, they ultimately decide that he's suffered enough and let him off the hook.
Though we never got to know her, Sarah Roman's death proved a pivotal point in "Chicago P.D.," forever altering the life of her brother Sean, and demonstrating to audiences that an off-screen killing can be just as powerful and consequential as any.
