In the Chicago P.D. episode “Justice,” after a hooded gunman opens fire on the patrol car of Officers Kim Burgess (Marina Squerciati) and Sean Roman (Brian Geraghty), leaving Roman wounded, Burgess chases after the perp. When she thinks she finds him, she shoots. Problem is, there was no gun found at the scene. The surviving suspect turns out to be a 17-year-old honor student with no priors. ASA Peter Stone, who put Officer Voight in jail last year, is assigned to the case with State Attorney Mark Jefferies (Carl Weathers).
ASA Peter Stone is portrayed by Philip Winchester. He’s known for his roles on The Player (Alex Kane) with Sharon Stone, Strike Back (Sgt. Michael Stonebridge), 24: Live Another Day (Colonel Shaw), Camelot (Leontes), and Fringe (Frank Stanton), among others. Chicago P.D. airs Wednesdays at 10pm on NBC.
