Detective Lieutenant Chin Ho Kelly was a former highly decorated HPD cop before being wrongly accused of corruption which resulted in his career and reputation being tarnished.
For a short time, after Governor Pat Jameson's murder and Hawaii Five-0 being disbanded, Chin temporarily joined the Honolulu Police Department but after Steve was cleared, Hawaii Five-0 was reopened and Chin officially rejoined the team.
During high school, Chin was well known for his quarterback skills in football, although Chin admitted that he wasn't the best. He seemed to know Steve, his mentor's son, well. During his cop years, Chin was investigating a cold case around the time he lost his badge. It is unclear what the cold case was about, but $200,000, of the $28,000,000 of the cash and the evidence of the case, disappeared . Chin's uncle Keako's wife, Mele, was very sick and needed a kidney. Desperate to save his wife's life, as the family did not have enough money for Mele to get on the list, Keako stole the money. Chin was willing to take the blame for his uncle's crime. Sgt. Cage did everything he could to try to charge Chin with this crime, as he thought Chin stole the money. Eventually, Chin gave up his badge, and took a job as a security guard. His mentor, John McGarrett, was one of the few besides Kono Kalakaua, that believed that Chin was innocent. Chin left his ex-fiancé, Malia "for protection." In He Kane Hewa'ole (episode), they both had an awkward reunion. Uncle Keako wants Chin to reveal the truth of what happened after Mele passed away. It is unconfirmed of what happened.
Chin is an honest cop, despite the accusations made against him. He is very proud of the work he does, and is still hurt that the cops of HPD do not trust him because of what they thought Chin did. Chin is also shown to have intense loyalty to his family, as it was revealed that Chin took the blame for his uncle's crime and is reluctant to tell the truth about what happened. Chin has never thought of doing something other than being a cop. Chin is very protective of his cousin, Kono, and is usually the one by her side. The one person that Chin looked up to was John McGarrett, and Chin has respect for his son, Steve, who is also the leader of Five-0. Like the rest of Chin's team, shows complete loyalty to Steve. Chin states that he has found a home with Five-0, and it is hinted that he does not want to go back to the HPD.
