Kimberly Hill is the corrupt former police captain of the Star City Police Department.
Following the death of Frank Pike, Hill became the new police captain of the Star City Police Department. 24 hours later, Ricardo Diaz sent an email to Hill containing surveillance photos of her father, sister and niece, blackmailing Hill into working for him, she was called to an operation at Star City port, hoping to catch Cayden James. They met an A.R.G.U.S. agent, Alex Scott, but he was shortly electrocuted remotely by James. Sometime later, after James' threat to detonate a thermobaric explosive above Star City, Hill took calls in an attempt to rally everyone together, After Cayden James was arrested, Hill allowed Diaz to enter the interrogation room that led to Cayden James' death. A few days later Hill was visited by District attorney Sam Armand, who asked for the police force's full support in taking down Mayor Oliver Queen.
After discovering there are several members of the Star City Police Department working for Diaz, Dinah Drake and Quentin Lance worked together to find out how many police officers are corrupt; during their investigation, Dinah discovers that Hill is one of them.
Oliver eventually confronts both Hill and Armand in his office, revealing that he knows they are working for Diaz, she claims that he threatened the life of her family if she didn't comply, he gives her the opportunity to do the right thing, and also promises to protect her family, however (out of arrogance) she refuses to do so, leaving him no choice; Oliver fires them both. Before cleaning out her desk, Hill fires several police officers who refuse to work for Diaz; including Dinah and Nick Anastas.
After Oliver used a device that Felicity made on his wrist to copy all of Diaz's files (that contain a list of every individual under his payroll) and gave it to Samanda Watson; Hill was arrested along with all the individuals under Diaz's payroll by the FBI.
Similar to Quentin Lance when he was working with Damien Darhk due to the threats made against his daughter, Laurel Lance, Hill was forced to cooperate with Ricardo Diaz because of this. Hill is proven to prioritize the safety of her family above all else such as when she allowed Diaz to murder Cayden James in her custody, cover up his drug operations, and relieve all the clean cops of their ranks for refusing to become corrupted.
Hill is proven to be quite arrogant; before Oliver Queen had fired her, he gives her the opportunity to do the right thing, and also promised to protect her family, however, she refuses to do so, which left him no choice but to fire Hill.
However, unlike Quentin, Hill lacks any redeeming qualities; while the former ultimately did the right thing by turning against Damien Darhk, she only kept on disgracing herself, after being fired by Oliver, she held a press conference with Sam Armand to manipulate the public into believing that Oliver fired her and Armand because they were investigating him for being Green Arrow even though Oliver fired them because of their ties to Diaz; unfortunately, this ultimately backfired, after Oliver obtained evidence of Hill's crimes and gave it to Samanda Watson; leading to her getting arrested by the FBI and exposing her crimes to the public.
These negative traits of Hill's, is what eventually led to her deserved/justified incarceration.
