Brett Mahoney

"You guys aren't alone in this, you understand? Fisk put a lot of my brothers and sisters in the ground, and none of us have forgotten that. If you can find a way to bring down that son of a bitch, every cop in the city is gonna have your back."

- Brett Mahoney to Foggy Nelson and Karen Page

Detective Sergeant Brett Mahoney is an officer with the New York City Police Department. As a police sergeant, Mahoney had assisted Nelson and Murdock in bringing down the crime empire of the criminal Kingpin named Wilson Fisk, while he had also briefly encountered the villainous Kilgrave as well as the anti-hero Jessica Jones. Following his brief investigation, Mahoney hunted down and eventually arrested the vigilante known as the Punisher, after the Daredevil had caught him, resulting in Mahoney being promoted to Detective Sergeant, where he continued to take an active interest with the Hand's activities within New York as well as dealing with the ongoing investigation revolving around the Punisher's crusade.

Once Wilson Fisk was released from Ryker's Island, following making a deal with the FBI, Mahoney took a personal interest in following the case, assisting Foggy Nelson with his attempt to run against Blake Tower as the District Attorney in order to ensure that Fisk was put back behind bars. Following a long and difficult battle to stay ahead, Mahoney assisted Nelson and the Daredevil with getting the evidence needed to prove Fisk had continued all his criminal activities upon being freed, using the posthumous testimony of Ray Nadeem, allowing them to have Fisk and Vanessa Marianna sent back to prison once again for their many crimes against New York City.

Meeting Foggy Nelson
"We've been enemies since we were four, Brett."

- Foggy Nelson to Brett Mahoney

Brett Mahoney was born and raised within New York City's Hell's Kitchen to his mother Bess Mahoney. Since he was a young boy, he has had a strong friendship and rivalry with another local boy named Foggy Nelson. When he grew up he became an officer of the New York City Police Department where Mahoney continued his friendship and rivalry with Nelson, who had started up his own law firm, Nelson and Murdock and would turn to Mahoney for tip offs regarding new cases which he could get involved with.

Working with Nelson and Murdock
"Please stop giving my mom cigars, Foggy." "What? She'll outlive us all."

- Brett Mahoney and Foggy Nelson

While on duty Mahoney ascended the stairs of the in Hell's Kitchen. As he walked along the streets he was greeted by his childhood friend and rival Foggy Nelson, now working as a lawyer. Nelson handed him a package of cigars for his mother Bess as a gift. While not happy with Nelson giving his mother cigars he did accept them. Before continuing his journey he indirectly promised Nelson to give him a heads up when an interesting case arises that Nelson's law-firm, Nelson and Murdock could get involved with.

Aiding New Yorkers
"Homicide, female suspect found at the scene, definitely qualifies as interesting." "She hasn't been charged yet?" "Assistant D.A. hasn't made the call yet."

- Brett Mahoney and Foggy Nelson

Later that evening Mahoney stayed true to his word and called Foggy Nelson, informing him about a new homicide case involving a single female suspect named Karen Page who had seemingly murdered her co-worker with a knife in her apartment. Nelson and Murdock took on the case and quickly proved Page to be innocent of the crime having been set up; they even hired her as an assistant at their law-firm. While Mahoney was serving as the desk sergeant in the station, he was visited by Nelson's law firm partner, Matt Murdock. Murdock told Mahoney that they are working on a case for a dear friend of Mahoney's mother. Mahoney soon agreed to help, despite the fact that Armand Tully, who was attempting to evict residents from their homes, kept his activities just legal. Mahoney then left to find any copies of the complaints made against Tully and to see if it was possible for Murdock to talk with some of the officers involved with these interviews to find evidence for Elena Cardenas' case.

Chaos and Murder
"Multiple stab wounds. The ambulance got there quick, but my mom says all the family she knew about's passed on. I knew you were looking into her tenancy case. I thought you might be able to point us toward the next of kin." "No, she didn't have anyone. Just us."

- Brett Mahoney and Karen Page

Mahoney was tasked with controlling everyone who came to visit Detective Christian Blake, one of the police officers shot during a raid, seemingly by a masked man who had been working as a vigilante within Hell's Kitchen. Since the shooting Blake had been in a coma. One of these guests was Carl Hoffman, who had come to visit his own friend. Before allowing Hoffman to enter the room, Mahoney asked him to sign in before also checking what was in the bag - a meatball sandwich. Seeing nothing suspicious in the bag, Mahoney allowed him to enter the room. A few minutes later however, Mahoney heard a noise coming from the heart monitor inside Blake's room and he called out to Hoffman to see if something was wrong. When Hoffman would not answer their calls, Mahoney, together with a few other agents, attempted to open the door, which was blocked by a chair from the inside. When they were finally able to force the door open, they found Blake lying dead in his bed, having seemingly been murdered by the man in the mask and Hoffman is laying on the ground, unconscious, having also been attacked and knocked unconscious by the vigilante. When his mother's friend and Nelson and Murdock's elderly client Elena Cardenas was murdered outside her home by a junkie who had stolen her purse, Mahoney personally took charge of the case and phoned their offices to inform them all of her death. Foggy Nelson, Karen Page and Matt Murdock arrived to identify the body. Mahoney explained what had happened to her and asked if she had any family left, they explained she did not and promised to take care of all the funeral arrangements. Both Nelson and Page cried over the death of their own friend, while Murdock remained silent.

Encounter with the Masked Man
"Hey you're the guy, the one that killed Blake and shot those cops!" "I didn't kill Detective Blake, or shoot those cops. Blake and Hoffman were dirty, working for Wilson Fisk, along with a lot of others from your precinct. I'm not the bad guy."

- Brett Mahoney and the Masked Man

Mahoney was one of the first officers of the New York City Police Department who arrived on his own at the scene of a massive fire which had broken out at a Warehouse, which was discovered to be an illegal drug den run by Madame Gao where the Steel Serpent heroin was being made. As he explored the facility, Mahoney encountered the Man in the Mask who was attempting to quietly leave the scene. Mahoney raised his gun and attempted to arrest the man, noting that it was believed he was responsible for murdering Christian Blake and causing the Bombing of Hell's Kitchen. Before Mahoney could arrest the man however, he was quickly disarmed and knocked to the floor where the man told him that Blake and Carl Hoffman were dirty cops and were both working for Wilson Fisk. Having been pinned down, Mahoney was unable to do anything as the man claimed he was not the bad guy before escaping and leaving Mahoney to be found by other police officers as they pulled up at the scene.

Exposing Wilson Fisk
"The way things are going around here, I'm thinking about taking an early pension. Move my mom somewhere warm." "Be a shame. The only cop on the force we know for sure is honest."

- Brett Mahoney and Matt Murdock

Mahoney was approached by Foggy Nelson and Matt Murdock who requested any information Mahoney could give them about the activities going on at the Police Station. Mahoney reluctantly told them what information he had, although he noted that Murdock appeared to not be listening, he then told them that he was planning on retiring early and moving somewhere warmer so his mother would be safe, with Murdock noting Mahoney was the only cop they could trust. While working behind the desk in the police station, Mahoney was shocked to be approached by Detective Carl Hoffman, who arrived covered in blood. Hoffman told Mahoney that he wished to make a statement. With Mahony in the room along with some FBI agents, Hoffman finally confessed that he had been secretly employed for several years by Wilson Fisk to ensure that the police never could discover all his criminal activity, then explained that he had gone into hiding after murdering Detective Christian Blake and had then been rescued by the Man in the Mask and convinced to speak out. Through Hoffman's confession, the FBI were able to arrest several of Fisk's closest allies in the criminal underworld, including Turk Barrett, Parish Landman and even Major Randolph Cherryh and anyone else connected to Fisk's criminal empire. When several corrupt police officers were pulled from the station and arrested, including Corbin who screamed and cursed as he was being taken away, Mahoney watched from the sidelines as they were being arrested with a smile on his face, knowing that the police force in New York City had just become considerably less corrupt without Fisk in the picture.

Capturing Wilson Fisk
"I told you before, Sergeant, I'm not the bad guy." "Holy shit, it's you." "This man was a fugitive of the law, and I stopped him."

- Daredevil and Brett Mahoney

Despite being taken into custody by the FBI and driven towards jail under armed guards, Wilson Fisk soon escaped with the help of his soldiers and went on the run in New York City. While assisting with the man-hunt across the city, Mahoney eventually discovered Fisk lying unconscious on the ground in the wake of a fight with Daredevil, now wearing a red suit, standing over him. Although Mahoney initially held up his gun, he soon acknowledged Daredevil was not the bad guy. Mahoney informed the New York City Police Department that he had located Fisk and was bringing him into custody. While he handcuffed Fisk, Mahoney spoke with Daredevil and questioned what he should be called in his police report from now on, with his brand new costume, before allowing Daredevil to go free. While Fisk was taken to Ryker's Island to begin his sentence for his many crimes against New York, including the Bombing of Hell's Kitchen, Mahoney told his story to the press, who used the name of Daredevil for the first time in the New York Bulletin's story all about Fisk's arrest.

Kilgrave's Control
"Jessica Jones, you're free to go." "Mahoney, what are you doing?" "Captain's orders. Go. Now."

- Brett Mahoney and Oscar Clemons

Jessica Jones arrived in the police station carrying the head of a neighbor she insisted she had murdered by ripping his head off. While Jones was being questioned by Oscar Clemons, Mahoney and every other officer in the station fell victim to Kilgrave's mind control powers. Mahoney was sent to inform Jones that she was free to go, despite her and Clemons' objections. Once inside the main office, Jones and Clemons discovered that everyone in the station had frozen, aiming guns at each other or themselves, Mahoney himself then drew his gun and aimed it at Clemons while Kilgrave revealed himself. Mahoney continued to be a slave to Kilgrave's demands, laughing on cue whenever he then demanded it. Once Kilgrave had said his peace and had the security camera erased, he ordered Mahoney and everyone else to find the situation hilarious before forgetting everything they had witnessed, which they obeyed without any question.

Massacre at the Burren Club
"If you're here to chase ambulances, you might notice there are none." "Any leads on what happened?" "Oh, you wanna know what went down? Read about it in the papers like everybody else."

- Brett Mahoney and Foggy Nelson

In the wake of a shootout in which multiple of the key members of the Kitchen Irish were gunned down, Mahoney was called upon to keep the crowds under control, being questioned by members of the public about what had occurred. Mahoney was approached by Foggy Nelson who asked him about what had happened in there, although Mahoney just claimed he could not provide answers in regard to an active crime scene and asked Nelson to step aside. When Nelson noted that Nelson and Murdock had acquired a new client who may have been witness to the massacre, which Mahoney claimed was grounds for the New York City Police Department to arrest Nelson for withholding a witness from the police investigation, however he acknowledged they could be helpful to the NYPD with such a witness ready to help them. When Matt Murdock questioned why Nesbitt, who was among the dead, was wearing a Bulletproof Vest on such a hot night, to which Mahoney told another officer to tell those inside the Burren Club to keep their voices quiet. Taking them aside and noting that nothing they discussed must be leaked to the New York Bulletin, Mahoney explained to Nelson and Murdock that the District Attorney, Samantha Reyes was trying to find who was acting out these attacks, explaining that they believed that all of the recent killings were not just gang on gang crime but targeted assaults by some kind of military trained professionals. As they discussed who this killer was targeting, Mahoney recommended that they turn over their witness and walk away as New York City was about to explode with even more gang violence.

Aiding Grotto
"The whole force is split. Some cops want him off the street, others think he's making our jobs a whole lot easier. But if you ask me, it's only a matter of time before the wrong person gets caught in the crossfire."

- Brett Mahoney to Foggy Nelson

When Grotto was targeted by the Punisher, leading to him being ambushed while stayed at Metro-General Hospital, Grotto was then taken to the police station where Nelson and Murdock interviewed him to try and get a better understanding of his situation. Mahoney came in the interrogation room to offer Grotto some prison clothes for him to change out of his hospital gown, informing the group that they were still looking at the footage gained from the hospital attack to try and get some leads on who the Punisher was. Mahoney explained that Samantha Reyes, the District Attorney, was now currently sending her own people to discuss witness protection options for Grotto in the wake of the attack by the Punisher, with Mahoney telling them to take whatever deal was offered to them. Mahoney quoted Oscar Clemons about dealing with their witnesses before Foggy Nelson demanded to know more about who they were dealing with and who the attacker was now being paid by, Mahoney would only tell him that the shooter was clearly independent and not working with any other criminal gang during the attacks. Claiming that the shooter was clearly the vigilante type but claimed it was not like Daredevil as he noted that when Daredevil saved somebody from being mugged then all of New York City celebrated while now people only got hurt. When questioned about his own view point on the Punisher's actions, Mahoney noted that the New York City Police Department were split on their view as some celebrated him while some others wanted him off the streets. When Nelson and Karen Page noted people would copy Daredevil, Mahoney noted the Punisher was just the latest and the most dangerous.

Aiding Daredevil
"Hey, stay out of it. You hear me?" "I just wanna help, Sergeant." "No, you can't help. You're the problem! 'Cause of you, the uniform means dick. Cops are no longer preventing crime, we're just chasing it. Mopping up the mess that you people leave."

- Brett Mahoney and Daredevil

While picking up pieces from the Burren Club, Mahoney told another officer that they were almost done with the pick up from the Kitchen Irish Massacre as he took off his gloves and prepared to finish the investigation for the night. However once he was alone, Mahoney overheard a crash in one of the rooms of the club. Suspicious of what it may be, Mahoney drew his gun and began making his way towards the source of the noise somewhere within the next room. Mahoney entered a back room to find Daredevil was already there waiting for him, saying that he needed to know exactly what had happened to the Kitchen Irish there. Mahoney at first refused, noting that although Daredevil had helped capture Wilson Fisk that did not make them allies, however he soon admitted that the Irish had put a hit on the Punisher and people across New York City were getting hurt as a result. As Daredevil prepared to leave, Mahoney told him to keep out of the investigation, noting that his actions had started this entire mess, although Daredevil simply ignored Mahoney. However Mahoney was later called to a graveyard outside New York City were he held Daredevil at gunpoint before realizing that he was with Frank Castle, aka the Punisher. Attempting to put Daredevil into handcuffs, Daredevil told Mahoney to take Castle into custody for his killings including the Attack on Grotto and the Kitchen Irish and then take all of the credit in order to finally give the New York City Police Department the credibility which they desperately needed. Despite believing that Daredevil needed to face justice, Mahoney let him walk and took credit for bringing the Punisher into custody, claiming that whatever Daredevil was he was not the Punisher.

Detective Promotion
"Look, none of this is my problem. But all I know is, you go up against this DA and lose, the only funeral to attend will be your firm's. You're talkin' career suicide." "If we walk away we're letting him die."

- Brett Mahoney and Matt Murdock

In the wake of the Punisher's arrest, Mahoney was then promoted to Detective and stayed by the Punisher's side while he was treated at Metro-General Hospital. During this time Nelson and Murdock arrived at the hosptial where Mahoney had greeted them. Once they had all discussed Mahoney's promotion from Sergeant to Detective Sergeant, they then noted that their firm wanted to represent Frank Castle, despite him already being represented by Christopher Roth. Although Mahoney noted that most law firms wanted nothing to do with Castle and his case, they still expressed their interest. Mahoney took the group aside and noted that if they decided to go against Samantha Reyes and lost, then it would be career suicide, but Matt Murdock noted that if they did not try then Castle would undoubtedly be sent to the electric chair which they felt was unjust. Agreeing to allow them to speak with Castle, Mahoney had his men search Murdock, Foggy Nelson and Karen Page regardless and gave them strict instructions about how to address Castle while they were alone in the room with him, joking that if they did not do as instructed then he would finally be able to arrest Nelson as a result. While Nelson and Murdock were speaking with Castle, Reyes arrived at Metro-General and demanded they be removed, which Mahoney had no choice but to obey. While Reyes was speaking with Murdock however about if they had violated their legal rights considering their work with their deceased client Grotto who Castle had reportedly killed during his attack on the Kitchen Irish, Mahoney reappeared and informed them that Castle had now decided to allow Nelson and Murdock to be his lawyers from now onwards, much to Reyes' great annoyance, although she was forced to accept it regardless.

The Hand's Victims
"Do me a favor? Keep the details of this arrangement to yourself." "Details?" "Our mutual friend." "I have no idea what you're talking about."

- Brett Mahoney and Claire Temple

Having been called to the Farm, Mahoney had soon discovered to his utter horror a group of young children held in cages and almost completely drained of their blood, with Stan Gibson cradling his own son Daniel Gibson and begging Mahoney for aid. Sending Detective Sergeant Thompson to look after all of the children, Mahoney continued looking around the area until he discovered several pipes leading to boxes filled with the blood of the children, causing Mahoney to gag in utter horror at the new gruesome discovery. Stepping outside and organizing help for the children, Mahoney was found by Daredevil who had been the one who had found all of the victims. Daredevil told Mahoney that their priority had to be finding all those responsible, claiming he had seen nobody down there but noting they should start by investigating the who he believed were involved. Daredevil then told Mahoney to get all the victims somewhere safe, recommending Metro-General Hospital as there was someone there who Mahoney could trust, with Mahoney joking about Daredevil telling him how to do his job for him. Taking Daredevil at his word, Mahoney and Thompson arranged for all of the victims they had discovered to be taken to Metro-General to be quietly treated for their suffering. Just arriving at Metro-General, Mahoney personally thanked Claire Temple for her work with looking after the victims of the blood draining as they found solutions for keeping everyone brought there alive. While both Temple and Louis D'Esposito were working on keeping the victims temperature under control, Mahoney noted to Temple that he knew that they both had some kind of a relationship with the Daredevil and asked they keep it quiet, while Temple denied all knowledge of knowing the Daredevil, which Mahoney accepted with no further questions.

Page and Castle
"Besides making sure Castle's face is plastered across every TV channel and newspaper? The DA and the medical examiner are dead, the same asshole takes a shot at you, and so far nobody in this entire city's seen a damn thing. I'm sorry. That wasn't very professional." "Mmm. Like you said, it's been a long night."

- Brett Mahoney and Karen Page

Mahoney brought Karen Page into his police precinct in order to take a statement from her about the shooting that had occurred at her apartment, with Mahoney questioning if she had encountered the Punisher at any time during the shooting. Page insisted that she had not seen anything, claiming to have hidden just as soon as the shooter had attacked, so Mahoney sent Officer Powell outside to end the investigation so he could send Page back to her home. When Page asked how Mahoney was doing, he vowed to get Frank Castle to justice, noting how Samantha Reyes and Gregory Tepper had both been killed by a shooter during this investigation. Mahoney apologized for not being professional by complaining about these aspects of his investigation before telling Page that she would be taken to a safe-house by some members of the New York City Police Department in order to ensure she was protected from any future attack, telling Page before she left to contact him if she remembered anything at all about the shooting at her apartment. Mahoney was called by Page who informed him she spent some time with Castle where he had killed Chaney and Speed, and he had now intended to do something as the pier docks, so Mahoney arrived to find a series of corpses of some of the Blacksmith's men and one of the ships on fire in the wake of the Destruction of the Blacksmith's Ship. Looking all around, Mahoney acknowledged this would be the largest siege of heroin their police department had taken in years, while Page looked at the wreckage of the ship, believing Caste was dead and his corpse was somewhere still onboard the ship. By the next morning the police department was still clearing out all of the wreckage from the recent shootout and explosions left by the Punisher, so Mahoney then approached Page, who was watching Gosnell's corpse being wrapped up and taken away. Mahoney told Page she could go home, noting that the guards she had been given had all been demoted for doing such a poor job. They discussed if Frank Castle could have survived the explosion, which Mahoney denied, telling Thompson to take her home and promising Page that the nightmare she had been living was finally over.

Nobu Yoshioka's Attack
"It might surprise you to know that we do keep track of two things real well. Records of people you put away and incident reports. Records on everyone else." "Everyone else?" "That's what they were after."

- Brett Mahoney and Daredevil

Mahoney was assaulted by the Hand, whose members beat him up and broke his arm while they demanded all the files about Daredevil's activities, including who he had rescued and was therefore close to, which included Karen Page, Jerry and Turk Barrett among many others. Seeking some legal council, Mahoney contacted Foggy Nelson, hoping he could learn what the Hand wanted with information about Daredevil, which Nelson promised to assist him with. While working in his office that evening, Mahoney heard a noise and soon found Daredevil waiting for him. They discussed what had happened, with Mahoney explaining that the Hand had threatened his own mother. Mahoney admitted that due to the threats made by Nobu Yoshioka who was clearly in charge of the thugs, he had been forced to hand over all of the incident reports taken by the New York City Police Department of people Daredevil had saved and those he had put in prison. With all that information, Daredevil quickly turned around and left to confront all of those responsible. Arriving at a warehouse, Mahoney found the police in a standoff against the Hand, who had taken hostages inside. Having been told there were archers on the roof, Mahoney told his people to hold their fire, even when the door burst open. Mahoney witnessed all of the hostages running for safety, including Page who ran to Mahoney for aid. While Foggy Nelson also arrived, Page told Mahoney that the Hand wanted Daredevil and Elektra, so Mahoney had the roof lit up to help Daredevil in his fight against Yoshioka, which he won with the aid of the Punisher who shot some of the attacking ninjas.

Attack on Stan Ori
"Hold your fire! Stand down. Everybody, stand down. Let her go, Castle. There's no way out of this. Got the building surrounded. God damn it! I need a man on every floor! Move! Move! Move!"

- Brett Mahoney to Punisher

Mahoney was called to the scene of a seeming terrorist attack in which Senator Stan Ori was almost murdered while multiple bombs were being set off amid a shootout with the terrorists. Mahoney and members of the New York City Police Department arrived on the scene where multiple Anvil agents had been killed while the bomber, Lewis Wilson had taken Karen Page as his hostage being his own explosive vest had seemingly been detonated inside the hotel kitchen, killing Wilson. While Mahoney and his armed unit stood outside the kitchen to block the exit, Page's voice called out for them to not fire as she stepped out with Frank Castle hiding behind her, holding his handgun under her chin. Mahoney ordered his men not to fire as he demanded that Castle let Page go and surrender himself, however Castle ignored what was being said and moved towards the elevator. With his men unable to stop him, Castle pulled Page inside the elevator and then got away, before seemingly vanishing from the building as Page was allowed to go free, much to Mahoney's great frustration.

Russo Questioning
"When is the last time you talked with Frank Castle?" "The last time? Couple years now. Up until yesterday, I thought he was dead." "This look like the work of a dead man to you?"

- Brett Mahoney and Billy Russo

Following the incident, Mahoney returned onto the crime scene and interrogated Billy Russo, first asking him directly about Lewis Wilson, who Russo had offered a job at Anvil to, although Russo insisted that he had refused to give Wilson a job in contract work, fearing he was not mentally stable enough, noting it was done as a favor for a friend. Mahoney noted that Wilson was able to breach Russo's security, explaining that Isaac Lange's body had been found, leading them to believe Wilson had taken his gear to get past Anvil. Insulted by this accusations, Russo noted that Stan Ori was alive and Anvil had lost four agents, questioning if Mahoney was suggesting negligence on their part. Mahoney and Russo then debated over the role of an organization like Anvil, with Russo mockingly claiming that the New York City Police Department were often blameless and had rarely got anything wrong. Russo asked Mahoney if he ever served in the Armed Forces, with Mahoney claiming that he served through the police department, as Russo noted that all his men expected to lose their people and had spotted the surprise attack against them. Mahoney noted there was a large coincidence with Russo knowing Wilson while also having served with Frank Castle for several years, leading to Russo getting to his feet and insisted that either Mahoney arrest him for something or allow him to leave. As he prepared to walk away, Russo insisted that Mahoney speak with Ori about what happened before Mahoney questioned when was the last time Russo had spoken with Castle, as Russo insisted he had believed Castle was dead until a few hours ago, with Mahoney pointing to the crime scene and asking if it looked like the work of a dead man.

Questioning Madani
"Come on. Help me see it. You want me to see this big picture here, then paint it for me." "I don't think you believe Castle's a terrorist any more than I do. Question is, Detective Mahoney, is anyone willing to give him the chance to prove that before they shoot him down?"

- Brett Mahoney and Dinah Madani

Mahoney brought Dinah Madani inside of the room next, with Madani noting that she believed that if Frank Castle had entered in that room with the intention of killing Stan Ori, then he would most certainly have succeeded. While Madani claimed that solving this was the reason she was in there, Mahoney asked why she was on leave from Homeland Security, to which Madani explained that somebody had killed her partner Sam Stein, so Mahoney apologized for asking. Once Mahoney had expressed his sympathies about Stein's death, he asked why Madani had come to the scene of the terrorist attack on her first day back. Madani questioned what Mahoney thought had happened, to which he claimed the evidence suggested that Castle and Lewis Wilson had come in together to kill Ori, as Madani noted his previous experience in dealing with the Punisher should show the issue in this concept. Madani explained to Mahoney that she came to speak with Billy Russo in regard to his Anvil agents being involved in the attack that had killed Stein, suspecting his involvement. Madani explained how she had almost captured Castle before Russo had intervened, leading to a stand off between her and Russo until the New York City Police Department arrived and arrested them, and allowed Castle to escape. Mahoney questioned her over this, noting that Castle had killed Russo's people, to which Madani argued that there was no actual evidence that this was the case, believing that Castle had not actually killed anyone that day. Mahoney insisted that Madani help him see her view, as she claimed that Mahoney did not believe Castle was a terrorist, asking to give him one chance.

Witness Statements
"It's funny how you and Castle keep, uh, bumping up together. Okay. All right, in your opinion, why was he even here?" "I think he was looking out for me. Frank Castle's not a terrorist."

- Brett Mahoney and Karen Page

Mahoney brought Senator Stan Ori back into the crime scene, noting that being in the room could often help the witnesses figure out the details of a crime easier. Mahoney watched as the clearly shaken Ori noted how the Anvil agents had died while protecting him, claiming he had never even held a gun before that day. Ori then questioned if Mahoney had ever been shot at, which he confirmed he had been, as Ori noted it had happened incredibly fast and it was replaying in slow motion. Ori gave his version of events in which he claimed that Lewis Wilson had blown open the door before he had Frank Castle then came in together and tried to kill him, with Ori telling Mahoney that he had taken a gun and fired back at Wilson and Castle before running to get help as the pair captured Karen Page during all of the ensuing chaos. However when Mahoney interviewed Page next, she laughed at this claim, telling him that Ori was lying. Mahoney invited Page to tell her side, while she had noted her wish to return to the New York Bulletin to write up her story about what had happened there. While Mahoney noted that all the evidence suggested that Wilson and Castle had attacked the room at the same time, Page insisted that Mahoney should know from his previous work on the Punisher's case that Castle would never have been involved with the Bombings of New York City. Mahoney asked what Page's opinion on Castle being there was, with Page claiming that he had been looking out for her, insisting again that Castle was not a terrorist, despite Mahoney noting that even the Bulletin believed that he was. Page insisted that if it was not for the actions of Castle then Ori would be dead. Despite Mahoney still noting that Castle was crazy which made his actions unpredictable, Page simply told her version of events as she claimed that Castle had saved her life by jumping in front of Wilson's bullet, being saved by his Bulletproof Vest, before Ori had pushed her into Wilson's arms, forcing Castle to risk his life to save her, resulting in Wilson killing himself while Castle got Page to safety. Mahoney noted that Page should be arrested for helping Castle to escape, but acknowledged she was likely telling the truth. When Mahoney asked where Castle was now, Page confessed that she had no idea.

Foggy Nelson's Speech
"Wilson Fisk. His cushy new situation is a federally-funded slap in the face to every officer in this room." "No shit. Not sure what that has to do with you crashing this party, though."

This time, believing that he was not a criminal, Mahoney put the gun down and proceeded to arrest Fisk.
 * : Mahoney had eventually traded his Glock 19 for a SIG-Sauer P226 as he investigated the war between Frank Castle and local gangs, and the efforts of the members of the Kitchen Irish to locate Castle. He had his weapon on him when he came across Daredevil while investigating a shop owner who had been tortured, and when he arrested Castle.
