Things are about to get dark again when Chicago P.D. resumes this Wednesday. In the first half of the season, a serial killer case threw Voight (Jason Beghe) off his game, and no matter how much he tried to catch the killer, they were one step ahead. The case is personal for Voight because he lost someone he had grown to care about. It has taken the back seat for the last several episodes after all leads did not pan out, even as Voight left his duties in Chicago to pursue a potential lead in another city. The promo for the Chicago P.D. Season 11, Episode 12, “Inventory” narrows focus and dives into the case when a new lead appears, but nothing is what it seems.
