The officers include Sgt. Tia Pearson, and offiers Colleen Deegan, Mandy Curfiss and Rose Valentino.
Sgt. Pearson is a seasoned cop and Iraq War veteran, who has recently promoted to the rank of sergeant. Her fiancé, Adrian, is also a cop.
Officer Deegan, also an Iraq War veteran, is one of the only women in the Cincinnati PD's elite Central Vice Control Section. She works with a group of proactive officers, targeting dangerous criminals with strategic undercover operations where she often tackles drug dealers or goes undercover as a prostitute.
Officer Curfiss is a former victims' advocate in the prosecutor's office. She's described by TLC as "aggressive, outspoken, and relentless when it comes to chasing down criminals." Her fiancé Jason is also a Cincinnati PD officer.
Officer Valentino works the midnight shift in Cincinnati's notorious Over-the-Rhine neighborhood, where she spends her nights "hunting down some of America's most dangerous offenders," according to the show. She has a young daughter, Lily, and fiancé, Matt.
The Cincinnati PD is overseen by Chief Col. Thomas H. Streicher, Jr. and covers a 78.6-square-mile jurisdiction. The department's operation is divided among five bureaus — administration, patrol, resource, information management and investigations.
The department employs 1,092 sworn law enforcement officers serving Cincinnati's 333,000 citizens. In 2010, they received more than 280,825 calls for service; made 37,387 arrests; and investigated over 17,655 auto accidents.
