~ Hannah Choi

Hannah Choi (Krn: 최한나) is a main character appearing in Season 2 of Criminal Case, where she serves as the Tech Expert of the Pacific Bay Police Department.


Hannah, aged 26 and of Korean heritage, sports black hair, a button-up summer green police coat which consists of black buttons, two breast pockets and two police badges on each side. She is also wearing a binary shirt beneath her coat. She wears an army green track bottom with a mid-gray belt. In her right pocket of her bottoms, she carries an MP3 player, and holds a tablet as well as a pen-drive and tamagotchi with her left hand. For accessories, she has lipstick on and she wears a necklace with the Korean word "무사" (musa, roughly translating to "warrior") on it as well as a police badge.

Hannah's favorite animal is rat and her favorite dish is Mac 'N' Cheese. She is known to be snarky and rebellious, but hard-working, and is also known to be a smoker.

In her suspect appearance in A Killer Among Us, it is known that Hannah knows electronics and is a gambler.



Hannah was born and raised in Inner City. Her parents struggled with the Pacific Bay Immigration office for citizenship after migrating from North Korea, being blessed of Hannah being an American-born baby, but her parents did not become citizens until Hannah turned twenty-one.

Service in the Inner Chaos

As revealed in Eastern Promises, Hannah used to be a member of an anarchist organization known as the Inner Chaos in the past—something she regretted to this day but believed that she was not herself at the time and that the organization's aim at equality and freedom had attracted her. Hannah was the Inner Chaos' hacker, a profession she used to spread propaganda and other illegal things for the organization.

Hannah once ran a major hacking operation, a feat which got her caught by the Pacific Bay Police. Due to her good hacking skills, the police offered a deal to her—to either go to prison, or to join the police force and put her skills to proper use. Realizing she had been blinded by Inner Chaos, Hannah decided to join the Pacific Bay Police, thus making the right decision to leave the anarchists for good.

Events of Criminal Case

Ties with the Inner Chaos

At some point after Hannah's departure from the Inner Chaos, the organization ceased to operate. But much to her dismay, the anarchists returned after the murder of a Chinese immigrant in Inner City, where the organization always operated.

The Inner Chaos started causing troubles for the Pacific Bay PD, which did not surprise Chief Marquez much as she knew this was to come. Hannah then got stalked by her past as the Inner Chaos tried reaching out to her again by hanging up a banner at Sue Xiong's shop at the bazaar. The banner featured a code which redirected Hannah to Inner Chaos' webpage showcasing a picture of her with the caption, "We miss you Hannah!!" This was a nightmare for Chief Marquez since the anarchists were now trying to get back Hannah, as this was the reason as to why she had kept fearing for Hannah from the moment she learned about the return of the group.

The Inner Chaos was still led by Fredo Mancini, who was later on confronted by the police team of Frank and the player during the murder investigation of a local Irish priest. Although he was found innocent of the murder, he led the team to an old anarchist manifesto handwritten by Hannah back when she was a member of Inner Chaos. Infuriated about the manifesto's timeless authenticity, Hannah questioned Fredo without remorse about his reasons for preserving the manifesto she deemed outdated and even lambasting him for Inner Chaos' will to set things right through acts of violence as opposed to the Pacific Bay PD by doing good without the need of violence.

After closing the murder investigation of a Russian mobster's wife, the player—upon Hannah's request—decided to check up on Inner Chaos' recent activities along with her. The investigation handed them a locked prepaid phone at the Inner City Playground which eventually led Hannah to retrieve the last message sent from the phone. The message was sent by none other than Inner Chaos, to Sergei Yablokov—the second in command of Russian mafia boss Nikolai Kamarov. The message revealed that the anarchists were trying to reach out to Sergei, infuriating Hannah. However, she was relieved to hear from Sergei that he had rejected their offer already.

Going back to the station, Hannah realized it was time to stop Fredo as the Inner Chaos would become extremely dangerous if they managed to get help from criminals. She then requested the player not to tell anything to Chief Marquez about the incident.

Soon enough, Fredo was incarcerated for the murder of editor-in-chief of the Daily Dawn newspaper, Vito Pioni. He was then taken to trial, where he attempted to blow the whole place up by committing suicide-bombing, but to everyone's relief, Hannah managed to get hold of Amy's gun and shoot Fredo to death just in time, thus saving many lives.

Following the shocking event, Hannah could not believe she killed someone, but Chief Marquez consoled her and told her that she did an act of bravery. Hours after the incident, the Inner Chaos was shut down by Johnny Crossman—an influential member of the organization.

A Killer Among Us

Hannah was flagged as a suspect after she analyzed the drawing details found in Danny Moto's briefcase. According to her, the drawing was of a database that could answer any question a person asked, and it was powered by plutonium. Considering that plutonium was stolen in the last case, Amy wondered if Hannah obtained the plutonium from the heist, but Hannah denied it saying that it was nigh near impossible to get plutonium legally.

Hannah was interrogated once again after she confessed to her involvement in the heist. She was not the one tipping them off on the player's investigations, but the victim ended up tricking her into cracking the Mennagio's security code giving them access to the vault. But once the player started investigating the heist gang, she realized that Danny tricked her. Considering her past, she was furious at Danny for what he did and admitted that she was not sad about hearing his death, and until the player and Amy located the killer, Hannah had to stay locked up in jail.

Hannah was luckily found to be innocent after Frank Knight's arrest and his escape with Karen, his ex-wife, but the team needed her help in locating the fugitives. According to an analysis of Karen's tablet, the two escaped to The Wastes and she suggested that they speak to Roxie as she has gone there before. Analysis from a file found in the junkyard also revealed everything about the heist as well as the plutonium theft. According to Hannah, Karen was the sixth person as well as the true mastermind behind the heist. She organized the heist so Louis De Rico could steal the plutonium, but due to his death there had to be a change in plans. Amy wondered if Karen stole it herself, but Hannah revealed that Frank stole it during the last investigation. Amy was shocked that Frank would do this voluntarily, and suggested that she and the player speak to Russell regarding Frank's motives. Hannah was spoken to one last time for help before the player and Amy went to the Wastes. She suggested that they use some top-of-the-line helmets she ordered in order to protect themselves from sandstorms, and they went to the armory to get them.

The Final Countdown

Hannah was a heavy contributor when she was able to put her digital skills to full use allowing Amy and the player to both bring Frank's killer to justice and to defeat Albert Tesla once and for all. While the team was in Tesla's virtual reality, Hannah made a clearer picture of the hologram that revealed that the killer wore a gas mask. After Bobby Prince was revealed to be the killer, Hannah was able to fix the helmet the player had sent to her while also making a helmet for Amy for them to enter the virtual utopia without Tesla's help.

In order for the team defeat Tesla, Hannah had made a digitized gun and hid it among some flowers so that Tesla would not know of her plan. The team was able to find it, and Amy destroyed both Tesla's virtual body and his brain. With Erikah Mabayo acting as a soothsayer of sorts, Amy and the player made a safe return back to the physical world after besting Tesla in a difficult fight.

During Frank's funeral, Hannah felt that Frank's treason in Paradise City was a turning point in his life, but Andrea made one thing clear—he fought for what he believed in, had to break rules to do greater good, and atoned himself to sacrifice himself to save Pacific Bay from Tesla. Andrea felt Frank deserved a proper funeral, so the team attended to Frank's burial, and although she admitted that she butted heads with Frank, Andrea addressed Frank as a friend as she placed the detective to rest.


As the Tech Expert of the Pacific Bay Police Department, Hannah has the responsibility of taking care of all the necessary digital/technical analyses, and to inform the team of such results after a certain amount of time or a speed-up process using Criminal Case Cash. Her task-wait rates vary depending on the difficulty of the task, but they all cost 1 Criminal Case Cash per 30 minutes.
