The investigations are conducted jointly by the Homicide Squad and the police department where the death occurred. When requested by municipal departments, the Squad sometimes assists in attempted murder cases, depending on the severity of injury inflicted and the complexity of the case.

The Cold Case Homicide Squad is responsible for the investigation of all cold case homicides within Bergen County. A murder investigation is deemed a cold case once a year has passed since the murder and no arrest has been made.
