Biography[]
History[]
Kelton's career as a superintendent for the Chicago Police Department was politically motivated and ambitious, with the goal of running for mayor. At some point during 2016, he was the commander of an area where a serial killer who raped victims was active. However, Kelton wanted to make sure the crime statistics in his district did not go below satisfactory, so he had his detectives shut down the case and turn away the FBI.
Katherine Brennan, another greedy and corrupt police officer, would help him with his campaign, who Kelton used to mooch off of.
Chicago P.D[]
Trust[]
Kelton hosts a fundraiser and gives a speech on how he wants to stop gangsters and criminals. In actuality, however, the fundraiser Kelton started raised lots of money, so he gave it to defense attorney Bernie Hoffman so he could deliver money to gang leader Andre Griffin, who helped him with the mayoral campaign. Unfortunately, Andre Griffin would betray him by murdering Bernie Hoffman and fleeing the scene.
Brennan and Kelton talk to Voight at the crime scene and Kelton says that he did see Hoffman but only at the fundraiser. He then demands Voight and his crew find out what happened to Bernie before he leaves the scene with Brennan at his side.
After delivering a campaign speech outside a church, Kelton is approached by Voight, who questions inconsistencies in Kelton’s timeline. Voight points out that Kelton wasn’t last seen with Hoffman at the fundraiser, as he had claimed. Kelton admits he visited Hoffman but insists nothing seemed unusual. Suspicious, Voight asks to inspect Kelton’s service weapon, which Kelton hands over before leaving.
Concerned about the investigation, Kelton instructs Brennan to tip off Griffin, warning him that the police are getting too close. In response, Griffin murders his own cousin and wounds Officer Kevin Atwater.
Later, Kelton visits Intelligence, seeking updates on the case. Voight keeps his answers vague, prompting Kelton to demand clarity. Voight bluntly accuses Kelton of being involved, though he stops short of presenting hard evidence. The tense conversation ends with Kelton warning Voight about the risks he’s taking — a warning Voight throws back at him before Kelton storms out, furious.
Following Griffin’s arrest, Brennan pressures Voight to let Griffin go, arguing the evidence is too weak to hold him. Voight refuses, confronting Brennan about her meeting with Griffin and accusing both her and Kelton of deeper involvement. Brennan defends their actions and ultimately succeeds in getting Griffin released, much to Voight’s frustration.
Later, Voight spots Kelton and Brennan campaigning publicly. Ready to confront them, Voight is intercepted by Halstead, who stops him from causing a public scene. Brennan and Kelton walk past Voight, aware of his hostility.
Outrage[]
Kelton refuses to authorize funding for Intelligence’s heroin investigation because it involves Matthew Garrett, a criminal who had recently sued the department for wrongful arrest. Kelton orders Voight to back off the case, but Halstead finds grounds to continue pursuing it. When Garrett is later found murdered, suspicion immediately falls on Halstead, with Kelton adding to the pressure by discussing the case with Tillman.
Frustrated, Voight confronts Kelton, demanding to know why he is targeting Halstead. Kelton points to Halstead’s past history with Garrett and the fact that his body camera was turned off, warning that if Halstead is guilty, there will be no saving him.
Night In Chicago[]
Kelton meets with Ray Price over dinner in an effort to secure his political endorsement. However, Price refuses to back him, and Kelton leaves the meeting, briefly passing Voight on his way out.
Later, following an officer-involved shooting during Atwater’s undercover assignment, Kelton summons Voight to his office. Furious over the incident, Kelton criticizes Atwater for not doing enough to prevent the victim’s death and warns Voight that if Atwater faces any fallout, his career in the department will be over.
The Forgotten[]
While searching for a kidnapped confidential informant, the Intelligence Unit uncovers a possible cover-up involving a 2016 serial killer case. Detective Leo Hernandez alerts Kelton that Intelligence is digging into the old investigation, prompting Kelton to dispose of crucial evidence.
Kelton later meets with Voight, who points out that Kelton oversaw those cases and presses him about any potential suspects. Voight also asks Kelton to locate Detective Hernandez, which Kelton agrees to, but he soon suggests that Homicide should take over the investigation, given Voight’s personal connection to the victim. Voight refuses to hand the case over, so Kelton advises to at least loop Homicide into the process.
When Voight later confronts Kelton about the missing evidence, he demands the FBI profile tied to the serial killer. Although Kelton denies involvement, Voight reveals that he spoke to the review board and knows Kelton accessed the 2016 files. Voight insists he only wants to find his friend, but Kelton claims he doesn’t know where the file is before leaving to take a call.
Kelton then directs Homicide to the warehouse where the serial killer, Steven Sawyer, is located. Detective Donahue ends up shooting Sawyer before Intelligence can intervene. By the time Voight’s team finds the kidnapped C.I., she has already died. Furious, Voight assaults Donahue and orders him to deliver a message to Kelton; that be is coming for him.
Pain Killer[]
Following Ray Price’s shooting and hospitalization, Voight suspects Kelton’s involvement. Kelton visits the hospital, telling Voight and Halstead that while he and Price had been political rivals, he still had respect for him. He then goes to speak with Price’s wife and daughter.
Later, after a judge is shot, Kelton is seen surrounded by the press alongside his campaign advisor, Blair Williams.
During a hostage situation at Stateville, Kelton steps in and pushes for S.W.A.T. to eliminate the suspect quickly. Voight objects, arguing that rushing in could endanger the hostages’ lives. He proposes entering the room himself to negotiate and create an opportunity for a cleaner shot. Kelton agrees to the plan, and Voight engages the suspect, trying to de-escalate the situation while also warning him about the snipers outside.
Kelton grows frustrated as Voight deliberately blocks the snipers’ line of sight to prevent an immediate kill. Eventually, the suspect moves into an open position, allowing the snipers to take a fatal shot and end the standoff.
This City[]
After two murders spark tensions between rival gangs, Kelton responds by putting all available resources on the case. Needing to ease the violence, he strikes a temporary truce with Ray Price and has Intelligence work with them to broker a peace deal.
However, the plan backfires when a gunman opens fire with a MAC-10 during the meeting, killing a civilian. Later, in Voight’s office, Kelton admits how badly the situation was mishandled. Tensions rise further when Kelton and Price argue over who’s to blame, until Voight steps in to break it up. Voight promises they will find the shooter, and Kelton urges him to do so.
Once Voight locates the killer and secures a witness, he shares the information with both Price and Kelton. But Kelton, seeking political advantage, makes a public statement revealing the existence of a witness. As a result, the witness is forced to flee Chicago for their safety. In the courthouse afterward, Voight confronts Kelton about the damage he caused, but Kelton simply walks away without responding
What Could Have Been[]
Kelton’s campaign specialist, Blair Williams, is murdered, and Ray Price is arrested for the crime. With Price now out of the race, Kelton finds himself losing his biggest competition for the mayoral seat.
Sacrifice[]
After a crew steals a truck loaded with pharmaceuticals, Brennan shows Voight a newspaper article that casts Kelton in a negative light. Brennan urges Voight to solve the case, but Voight warns her it will take time. She presses him, acknowledging his dislike for Kelton, but insists that Voight needs to help Kelton if he wants to avoid further complications. Just as the conversation ends, Adam Ruzek arrives to update Voight on the progress of the investigation, and Brennan leaves.
Eventually, the Intelligence Unit solves the case, clearing Kelton of the political damage caused by the robbery.
Confession[]
Voight visits Katherine Bradley to deliver an email from Kelton, which reveals that he could have prevented Steven Sawyer from killing as many people as he did.
Tensions rise as Brennan’s support for Brian Kelton’s mayoral campaign reaches a breaking point. She’s threatened with the release of past allegations against her, prompting Kelton to force her into a confession. He pressures her into admitting that she allowed the serial killer to continue his rampage, threatening to charge her for everything she did to protect him.
After Brennan publicly takes responsibility for Sawyer’s murders, she resigns from the Chicago Police Department. Voight visits her afterward, and she warns him that Kelton is now coming for him.
Reckoning[]
With the day of the election closing in, Voight becomes more and more desperate to find some way to expose Kelton before he wins the election, becomes Mayor, and disbands the Intelligence Unit. Despite getting a lead on a gangbanger Kelton has a close relationship with that could help expose him, Voight arrives to find the gangbanger, Wilson Young, dead, immediately suspecting Kelton had him killed to cover his tracks after the corrupt Superintendent tried to assign Intelligence to a double homicide that Homicide stalled investigating. When Kelton shows up on the scene of Young's death, Voight tries to confront him and expose the truth, but Kelton is able to keep cool and deny any of Hank's accusations against him.
Despite Voight's efforts, Kelton wins the election by a landslide and becomes Mayor-elect. However, that night, CPD is called to Kelton's house for a report of "shots fired". When some of Voight's detectives arrive first on scene and go inside to check, they find Kelton, slumped on the floor, riddled with several gunshot wounds, a look of shock frozen on his face, dead. Voight is seen driving away from the area as more and more units converge to find the Mayor-elect and Superintendent shot dead, rendering his victory in the mayoral election pyrrhic.
Doubt[]
Acting Superintendent Crawford immediately orders a full investigation into who murdered the Superintendent and Mayor-elect, with Voight and his Intelligence Unit, since they could no longer be disbanded as that was part of Kelton's reform of the CPD when he became Mayor, but with him dead, his plans went with him, taking point. During the investigation, Voight discovers that the assassin was Kelton's own former second-in-command, ex-CPD Deputy Superintendent Katherine Brennan. She reveals to him that she confronted Kelton after he won, reminding him of her part in getting him where he was, but he laughed her off and told her he didn't need her anymore and never wanted to see her again. Furious at his betrayal of her trust after everything she sacrificed to allow him to win the election, Brennan used the gun she recovered from a former CPD officer who died about a two weeks earlier from a heart attack, who she had been helping at the time, to shoot Kelton dead, thus why his corpse was found with a look of shock on his face, stunned by Brennan deciding to kill him in vengeance for double-crossing her. Rather than arrest her for murdering her superior officer, Voight gives Brennan the choice to take her own life and leaves to let her get her affairs in order before committing suicide. However, Jay Halstead and Hailey Upton go behind Voight's back and prevent Brennan from taking her own life and arrest her. When she is brought back to the 21st Precinct and handed over to Sergeant Platt to be booked, she believes Voight betrayed her and called Halstead and Upton to arrest her after he gave her the freedom to commit suicide. After Platt and Upton take her away, Voight furiously confronts Jay for interfering in his actions and tells him that if he keeps doing it, Voight has no use for him in the Intelligence Unit anymore and wants him out of the precinct before storming off fuming in rage.
Kelton is still given full honors after his death with being given final salutes by the CPD as his body is taken away in a CFD ambulance to be autopsied by the Medical Examiner, but with him dead, along with his plans for the Mayor's office, Voight and his Intelligence Unit remain a part of the CPD and are not disbanded.
