What are officers called who follow up on crimes and collect evidence?

Detectives are specifically trained law enforcement officers who focus on investigating crimes after they have been reported. Their primary responsibilities include gathering evidence, interviewing witnesses, and analyzing information to solve cases. They often handle more complex investigations that require deep analytical skills and attention to detail, which distinguishes them from patrol officers who are primarily engaged in responding to calls and maintaining public order.

While both detectives and investigators can refer to individuals involved in crime-solving, the title "detective" typically signifies a specific rank or position within a police department that is dedicated to investigations. Investigators can work in various settings, including law enforcement, but detectives are more commonly associated with and recognized for their role in criminal investigations.

Patrol officers are essential to the initial response to incidents and maintaining safety in the community, but they usually do not engage in the detailed investigative work. Police chiefs, on the other hand, are high-ranking officials responsible for overseeing the entire police department, including the detectives and their operations, rather than conducting investigations themselves.
