Watch a clip from Wednesday's episode

Liz Raftery

On Wednesday's episode of Chicago P.D., what starts as the pursuit of a known gangbanger becomes a grisly investigation into a child murderer.

After Burgess (Marina Squerciati) and Roman (Brian Geraghty) discover the body of a missing 8-year-old boy, the crime leads the Intelligence unit down a series of unforeseen paths. And the case gets even more heart-wrenching when the victim's young sister shows up to plead with Voight (Jason Beghe) in person to find her brother's killer. Will Voight and the rest of the team be able to fulfill the promise he makes?

Check out an exclusive clip from the episode below.

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