Pirelli (Allen Hamilton), a retired Chicago police officer who was the partner of Cusack's father. At a hearing, Kopalas decides to back Cragie's story. Cusack testifies truthfully that he cannot comment on the incident in question because he arrived after the fact. However, it is revealed that Cusack once submitted a transfer order to have Cragie moved out of his unit. Other officers resent Cusack for breaking the unwritten "code of silence" which says officers should never report the errors or misconduct of their colleagues. Only former partner Detective Dorato remains loyal to Cusack. Pirelli ends up dead and Diana missing. Cusack races toward the Comacho hangout and puts out a radio call for backup, but due to the hearing, other officers refuse to respond. He fights off Luis and other Comacho gang members by himself. Luis tells Cusack he wants Tony Luna, otherwise Diana dies, painfully and slowly. Dorato tips off Cusack that Tony Luna was lying low in Wisconsin, returning to Chicago that night by train. Cusack waits outside the station, watching as Luna climbs into Scalese's limousine. Scalese chastises his nephew for igniting a gang war. The driver notices Cusack following and a wild chase ensues. The limo strikes a stalled car and overturns onto its roof, with Luna and Scalese killed in the explosion. Cusack, in need of a partner, returns to police headquarters and retrieves the Prowler robot, single-handedly launching a full-scale attack on the Comachos' lair in East Chicago, Indiana. Other detectives berate Cusack for his actions. Kopalas, fed up, tells everyone off and confronts Cragie, stating that he will no longer lie for him. He reveals to the squad room that Cragie planted the gun on the teen he killed. Cusack takes down the remaining Comacho members. Luis, wounded, enters a bathroom where Diana is bound. He raises a hammer, but Cusack shoots and kills him. Backup arrives at last. Cusack places Diana in the care of the CFD ambulance crew. Commander Kates asks will he come in the next day, and Cusack, finally having regained the respect from his fellow officers, agrees. Dorato gives him a ride back to headquarters.
