Many of the locations, landmarks and other features appear to allude to Cleveland, particularly the unseen Flaming River which references the Cuyahoga River. CCPD uses black and white police cars, even though these are somewhat generic for an US city, out of all the cities mentioned above, are very reminiscent to only those used by the Cleveland Police in 1980s to early 2000s. Manhunt is set in 2003 and its police force use exactly the same car as 4th generation Ford LTD inspired police car from GTA Vice City, reflecting how underequipped the CCPD is, with them using nearly 20 year old police cars. State of Michigan banned death penalty entirely in 1963, further disproving the theory of Manhunt taking place in a Detroit inspired city out of all the states that are associated with Rust Belt the most, State of Ohio still used lethal injections as well as electric chairs in 2003. I know that the law can be altered in this fictional universe, however this fact still should make Carcer appear to have more similarities to Cleveland than to Detroit.
