| |  | |  | | Police Investigations |
| The function of the Investigation (Detective) Bureau is to perform follow-up investigations into serious and involved crimes that cannot be handled by patrol alone. Police detectives typically receive preliminary investigations, assess leads, contact witnesses, interview suspects, prepare and serve search warrants, and prepare cases for presentation to the District Attorney. Detectives work normal business hours, wear business attire, and drive unmarked vehicles. They are classified as police officers, and have all the discretionary powers to stop, detain, and arrest that uniformed officers have. |
