Voight (Jason Beghe) may have found a way to save Olinksy's (Elias Koteas) badge.

This week's Chicago P.D. finds the veteran detective being investigated by Woods (Mykelti Williamson) for his role as an accomplice in the murder of Bingham (Joseph Sikora), the man who killed Voight's son. While Voight is the one who committed the brutal crime, Olinksy watched him do it and then helped the Intelligence head dispose of the body and then move it once authorities were sniffing around the burial site.

In an exclusive sneak peek of the episode, titled "Payback," Voight informs Olinksy that he has found the identity of a witness who could tie him to Bingham's murder. "I got this, Al," he assures his longtime friend and literal partner in crime.

Though Voight says he's simply going to look into this witness and "see what he's about, maybe catch him dirty," something tells us it's not going to be simple as that. As we've seen in the past, Voight will stop at nothing to tie up loose ends and things aren't looking good for this potential witness.

Chicago P.D. airs Wednesdays at 10/9c on NBC.
