Grimsborough is a major city in the United States, and the main setting for The Conspiracy, the fifth season of Criminal Case. The Conspiracy marks Grimsborough's second appearance in the game, after the first season.
The new rendition of the city, which is composed of ten districts, is much more detailed, larger, and livelier than ever before, despite a mysterious object from the sky crash-landing into the Grimsborough forest a year earlier, bringing new secrets with it. The Grimsborough Police Department (GPD) returns as the law enforcement agency that serves the city.
The now-restructured Grimsborough, which features a total of sixty cases, houses ten districts:
Fairview is the first district of Grimsborough investigated in The Conspiracy. It focuses on catching the Rocket Cow Killer, a serial killer who is using a mixture of amlodipine and the Rocket Cow energy drink to induce heart failure in their victims. It also focuses on the player readjusting to the changes Grimsborough and its police department has undergone when they were gone.
Money Mile is the second district of Grimsborough investigated in The Conspiracy. Also known as the Financial Center, it focuses on the aftermath of a major earthquake that struck Grimsborough, whose epicenter lied on the district. It also focuses on a suspicious artist using the earthquake to advance her career, along with the disappearance of Zoe Kusama, a social worker.
The Greens is the third district of Grimsborough investigated in The Conspiracy. Previously the dodgy and gang-ridden Industrial Area, the district now boasts tech startups and trendy businesses such as smoothie bars, thanks to the work of One-Tooth Sam. It focuses on investigating DreamLife, a tech company that has recently released an addicting virtual reality game and that owns the satellite that crashed a year ago. It also focuses on investigating mafioso-turned-businessman Tony Marconi and his possible connection to Zoe Kusama's disappearance.
Old Town is the fourth district of Grimsborough investigated in The Conspiracy. The historical district of Grimsborough, the district focuses on investigating The Higher Truth, a cult dedicated to enlightenment and reaching higher planes that has been making anonymous donations to DreamLife and their efforts to protect their crashed satellite in the forest. It also focuses on the excavation of the long-lost ancient city of Xerda.
Maple Heights is the fifth district of Grimsborough investigated in The Conspiracy. The most affluent district in the city, the district revolves around containing the deadly "Demon Fish" that had infested its flood waters as well as investigating who had made the fish resurface from the Xerdan caves. It also focuses on preparing for the team's infiltration into DreamLife's dome in the forest.
Misty Grove is the sixth district of Grimsborough investigated in The Conspiracy. Located in the city forests, the district focuses on investigating DreamLife's meteorite project under the dome. Specifically, it focuses on their research into the extraterrestrial element Berzelium from the meteorite, which can have either enhancing or suppressing properties on an organism's immune responses, and the resulting drug development and human experimentation from the research.
University is the seventh district of Grimsborough investigated in The Conspiracy. It focuses on investigating Rozetta Pierre's past before she founded DreamLife, and her connections to a secret student group called Ad Astra.
Spring Fields is the eighth district of Grimsborough investigated in The Conspiracy. The agricultural district of the city, it focuses on finding "Fornax" and the other three members of Ad Astra, with whom Rozetta Pierre is still collaborating with. Relatedly, it initially focuses on the effects of a corn shortage deliberately caused as part of Rozetta's plan to distribute a mind-altering drug across the city.
Airport is the ninth district of Grimsborough investigated in The Conspiracy. The district revolves around the continual efforts to bring down Ad Astra, especially in discovering the nature of and preventing the execution of "Plan Supernova" that involves a superhuman serum.
Newmark is the tenth and final district investigated in The Conspiracy. Boasting technical marvels from its rebuilding after the earthquake, it focuses on chasing the members of Ad Astra who have escaped prison and finding the bigger and more powerful conspirator behind the group who now plans to get rid of them and destroy the whole city in a quest for the enhancement of the human race.
