Events of Criminal Case
Chief Parker introduced herself to the player upon their return to the police department. She said that she ran a tight ship, but assured them they would get along just fine. She then allowed Jones to take the player to the zoo to meet up with the department's old coroner, Nathan.
After arresting the Rocket Cow Killer, Chief Parker tasked Jones and the player with finding the missing shipment of amlodipine. When they discovered that Rosamund had been working with an accomplice, Jones and the player presented their evidence to the Chief, who advised them to reinvestigate the high school.
After arresting Voodoo Vince's killer, Chief Parker was lured to The Maneater (a strip club) under false pretenses by Jones and Gloria. There, they surprised her with a party organized by Kiki Shae to celebrate her birthday. They then watched a performance by Jasper Everett, Amir, Gabriel and Ramirez. After the performance, Ray took her out to watch a 5-hour violin recital.
After arresting Mason Bloom's killer, Gloria, Rupert and the player told Chief Parker about their plan to get Rupert to intercept and impersonate a DreamLife scientist to infiltrate their dome. She commended Rupert for taking initiative but pointed out that the risk was high. She then authorized Rupert to learn as much as he could about meteorites and that they would adjust their plans accordingly.
After arresting Joshua Gibson's killer, Cathy found out that Dr Mortimer Pickering, the geologist who had been hired by DreamLife, had arrived in Grimsborough after a flight from England, and DreamLife had no idea Dr Pickering was already in Grimsborough. Cathy also found out that Dr Pickering had booking himself in for two nights at the Glitz Hotel. The team then came and informed Chief Parker about Dr Pickering. When being asked whether the team should head to the hotel, Chief Parker denied and suggested the team that we should formulate a plan to intercept him and make him cooperate.
Later, Chief Parker and the team came to Martine's lab to see if she felt better after being administered the antidote to the Demon Fish's neurotoxin. She was happy to see Martine was alright. After Martine said that she saw her husband, Ray, diving in the underwater cave. Chief Parker was surprised as Ray hadn't gone diving since college. In order to find out the reason why, Chief Parker and the player decided to ask Ray, who said that he wanted to help the team. In the end of the conversation, Chief Parker apologized to the player on behalf of her husband.
After arresting Mayor Martha Price's killer, Cathy was able to fit Rupert's watch with a communications microchip to help Rupert communicate with the team from inside the dome when he had to go undercover in DreamLife as Mortimer Pickering. Rupert and the player then went to Chief Parker's office to tell her that everything was in place. There, Chief Parker went over the plan to infiltrate the dome and told Rupert that his goal was to find out exactly what DreamLife was doing with the meteorite. She also told Rupert not to put himself in any unnecessary danger whatever he did.
After arresting Rupert's killer, the team was able to get everything which needed to access the lab in which DreamLife kept the mysterious meteorite. After that, Jones and the player spoke to Chief Parker, who authorized the team's infiltration into the lab, provided they do it in the dead of night as to not raise suspicion.
Later, Chief Parker, along with the entire team and Alex, headed to Rupert's funeral. There, Chief Parker gave the eulogy at his funeral, saying that Rupert's hard work and dedication had helped the police force solve an immeasurable number of crimes, and the team would always be grateful for that.
The nightfall after the funeral, Chief Parker told the team to head to DreamLife to infiltrate the meteorite lab.
After arresting Sam De Witt's killer, Rita, Martine and the player asked Chief Parker if she would make the teams for the GBPD paintball match. Chief Parker then agreed to help the team, saying that she knew enough about GBPD members' individual strengths to divide them into two balanced teams. She then gave the player their paintball outfit and told them to meet at the paintball arena when everybody was ready. Later, Chief Parker blew the whistle and started the paintball match, which later ended in a tie.
After arresting Kevin Charles's killer, Gloria and the player informed Chief Parker about their breakthrough. They informed her that Kevin had been killed because he knew the identities of all five of the original Ad Astra members. They then revealed that one of the members, "Fornax", was in Spring Fields. Since "Fornax" was also the name of the warehouse where DreamLife planned to ship the Protozane, Chief Parker endeavored to make the necessary arrangements to move the team to Spring Fields.
After arresting Mia Loukas's killer, Gloria and the player found proof that the mayor had paid for Brock to kill the player. The team then forwarded this concern to Chief Parker, who reasoned that the Mayor's affiliation with Ad Astra meant that they controlled all of the city's politics. They then reasoned that Joe was the reason why DreamLife was allowed to construct the dome and why Christian Bateman was released from prison early. She then told the team to head to the airport to confront him as soon as he landed home from his business trip.
After Denise Daniels unleashed her neohumans onto Grimsborough, Chief Parker ordered the team to evacuate residents. Later, when the team found Denise murdered, they found Chief Parker's gun near the crime scene, flagging her as a suspect. She said that she had lost it when she went out on patrol near City Hall as she helped evacuate the panicked crowds. Chief Parker then left to continue the evacuation.
Later, the team found a picture of Denise on which Chief Parker had written "ELIMINATE". Chief Parker then admitted that she had begun to feel powerless due to the escalation of crime in the city all stemming from Denise's actions. She felt stressed about the situation and she also felt sad over the lives that had been taken away due to it. In her darkest hour, Chief Parker felt that she needed to eliminate Denise, the mastermind, in order to stop the madness and protect the team. She then reassured the team that she would not have pushed through with it.
Chief Parker was found innocent when the team incriminated Denise's neohuman, Otto Kessel, in the murder and in taking over the neohuman army. Later, the team approached Chief Parker to get her approval on using a fake message of Otto in order to round up the neohumans near the hill so the team could take them on more easily. Chief Parker approved of the plan but asked the team how they would broadcast the message. When Rita suggested using City Hall's broadcast system, she then told the team to search for the access codes near the City Hall steps.
Later, the team reconvened to execute the final plan, with Rita volunteering to sacrifice herself to take the neohumans down. Chief Parker, Martine, Amir, and the player talked to her to ensure that she was willing to sacrifice herself. When Rita said she was ready to take the superhuman serum to end Otto and the neohumans' terror, Chief Parker joined the team in watching the battle from a distance until Rita blew up and killed everyone in the battle.
Two weeks after the battle, Chief Parker delivered a eulogy at Rita's memorial ceremony. She praised Rita for her sacrifice and announced that a memorial in her honor would be erected at the former site of the DreamLife dome. Five months after, Chief Parker and the rest of the team attended Amir and Jasper's wedding.
As the Chief of the Grimsborough Police Department, Diane requires reports from three different "teammates" (friends who play Criminal Case and are recruited to the player's team) before she can let the player advance to the next case of The Conspiracy. Besides that, she notifies the player each time they level up in the season.
Also, the player may choose Diane to join the investigation of each crime scene (in any case of The Conspiracy) and provide hint bonuses. She is available as a 5-hint partner. (This feature is only available in the mobile variant of Criminal Case.)
