Internal Affairs (1990) Timeline Explained – Every Event in Order

Peck targets Kathleen as retaliation for Avilla's relentless investigation against him. After Peck orchestrates the murder of Demetrio (the key witness) and learns that the IAD is closing in on him, he manipulates the situation by masquerading as an IAD investigator concerned for Avilla's welfare. This allows him to arrange an intimate meeting with Kathleen, which he uses to destabilize Avilla emotionally. When Avilla confronts Peck in the elevator, Peck brutalizes him, further escalating the personal war between them.

Foreshadowing: Earlier, Peck had insinuated to Avilla that he would go after his family, showing his intent to use personal attacks as a weapon.

Dennis Peck orders the brutal assault on Van Stretch, leaving him for dead. The attack occurs because Stretch is wavering in his loyalty to Peck after Avilla pressures him to testify against his partner. Peck also discovers that Stretch has been having an affair with his wife Penny, adding a personal betrayal to the professional conflict. The assault serves as both a warning to Stretch and a demonstration of Peck's ruthlessness toward anyone who threatens his operation.

Foreshadowing: Tensions between Stretch and Peck escalate when Avilla urges Stretch to cooperate with the investigation, and Peck's affair with Penny creates underlying tension.

Peck sustains his lifestyle through corruption, primarily working as a high-paid hitman for criminal clients. He executes contract killings for substantial fees, including a job for businessman Steven Arrocas who offers him $15,000 to kill his parents. Additionally, his wives are involved in lucrative real estate dealings that generate income. The wives, particularly Penny Stretch, manage interconnected properties that appear legitimate on the surface but are secretly funded by Peck's criminal proceeds.

Foreshadowing: Early in the investigation, Avilla and Wallace note the discrepancy between Peck's modest police salary and his apparent wealth.

The final confrontation occurs after Peck shoots Wallace during his escape from Arrocas' scene, then rushes to Avilla's home to hold Kathleen hostage at gunpoint. The IAD has been closing in on Peck, discovering the real estate connections among his wives and obtaining crucial testimony from Penny Stretch. With his criminal network unraveling and no way out, Peck takes desperate action. When Avilla returns home, he finds Peck holding Kathleen hostage, leading to a brutal fight where Peck beats and shoots Avilla in the leg before Avilla manages to shoot Peck in self-defense.

Foreshadowing: Peck's earlier attack on Avilla in the elevator and his threat against Kathleen establish his willingness to escalate to lethal violence.

The IAD builds its case against Peck through multiple breakthroughs. First, they discover the discrepancy between Peck's police salary and his lifestyle, leading them to investigate his finances. They uncover interconnected real estate assets among his wives, particularly when Penny Stretch cooperates and provides details about two murder victims linked to Steven Arrocas. Demetrio, a key witness, implicates Peck in Stretch's assault before dying. Finally, Wallace survives her shooting and identifies Peck as her attacker, providing the crucial witness testimony needed to formally charge him.

Foreshadowing: Early investigation notes highlight Peck's questionable lifestyle and the need to trace his income sources.

Arrocas shoots Peck after discovering him in a compromising situation with his wife. Rather than reacting with the jealousy Peck expects, Arrocas maintains control and shoots Peck in the foot as punishment for the affair. Most significantly, Arrocas had hired Peck to kill his parents, and when Peck braggadociously claims the contract killing is complete, Arrocas realizes the threat Peck poses. The shooting allows Arrocas to escape the scene while Peck is incapacitated, though Arrocas' parents are later found dead.

Foreshadowing: Earlier, Arrocas approaches Peck with an offer to kill his parents for $15,000, establishing both the contract and Arrocas' darker nature.

Wallace is shot by Peck as he flees the scene after the confrontation with Arrocas. When Wallace and Avilla arrive at Arrocas' location, they discover his murdered parents. During the chaos of Peck's escape, he encounters Wallace and shoots her, inflicting serious injury. Despite being wounded, Wallace manages to inform both Avilla and an ambulance driver that Peck was the shooter, providing the critical witness statement that connects Peck to another crime and strengthens the case against him.

Foreshadowing: Peck's pattern of eliminating witnesses and those who threaten his operation foreshadows his attack on Wallace.

The real estate holdings among Peck's wives serve as a money-laundering operation that hides his criminal income. The IAD discovers that all of Peck's wives own properties with mysterious financial connections, appearing to be legitimate businesses but actually funded by his corruption and contract killing earnings. Penny Stretch emerges as the key figure, orchestrating these dealings in secrecy. Her eventual cooperation with the IAD provides crucial evidence about two murder victims tied to Steven Arrocas, significantly advancing the case against Peck.

Foreshadowing: Early in the investigation, Avilla and Wallace note the lifestyle discrepancy that hints at hidden income sources.

Peck accepts the contract to kill Arrocas' parents because it represents a high-paying job that aligns with his criminal side business as a hitman. When Arrocas initially offers $15,000, Peck is insulted and demands a more lucrative fee, showing his self-awareness of his skills and the risk involved. The murder would have been a substantial payment for Peck, continuing his pattern of using his police position to facilitate serious crimes for profit. The fact that the job involves killing innocent people demonstrates Peck's complete moral corruption beyond just police misconduct.

Foreshadowing: Peck's lifestyle funded by corruption is established early, showing he operates as a professional criminal alongside his police career.

The affair between Peck and Penny Stretch (Van Stretch's wife) creates multiple complications in the case. It gives Peck leverage over Stretch, ensuring his loyalty through both fear and personal betrayal. When the IAD investigates, they discover Penny's central role in managing the real estate dealings that launder Peck's criminal income. Initially hesitant to cooperate, Penny eventually turns against Peck and provides critical testimony to Avilla and Wallace about two murder victims connected to Arrocas. Her cooperation becomes essential in building the case against Peck, directly linking him to the contract killing operation.

Foreshadowing: The tension between Stretch and Peck escalates when Avilla urges Stretch to cooperate, partly driven by Stretch's ignorance of the affair.

Demetrio is a key witness who is killed during a SWAT raid that was supposed to help Avilla and Wallace capture him. As the IAD closes in on crucial evidence about Peck's corruption, two SWAT teams storm the area, triggering a violent shootout that results in Demetrio's death. Before dying, Demetrio manages to point directly at Peck as the one responsible for Stretch's assault, providing the first concrete witness testimony linking Peck to the violent crimes protecting his operation. His death represents a significant setback for the investigation but also solidifies the scope of Peck's criminal reach.

Foreshadowing: The investigation's progress toward catching the witness creates the tension that leads to the fatal SWAT operation.

Avilla's marriage collapses because his obsessive focus on bringing down Peck consumes his personal life. The constant stress and time devoted to the investigation leave little room for his relationship with Kathleen. Worse, Peck deliberately targets Kathleen to hurt Avilla, masquerading as an IAD investigator to meet with her, then using the situation to emotionally devastate Avilla. This manipulation, combined with Avilla's neglect, creates an irreparable rift. The marriage ends in an explosive confrontation after Peck's assault on Avilla in the elevator and his manipulation of Kathleen, leaving their relationship destroyed by the corruption Avilla fought to expose.

Foreshadowing: Early in the investigation, Avilla's obsession is noted as affecting his personal life, foreshadowing the marital collapse.
