It is the mission of the Criminal Investigation Division (CID) to investigate crimes and other incidents, in the form of either preliminary activity or of continuing or follow-up activity, bringing each and every case to a successful conclusion; to coordinate all activities from other Divisions which are investigative in nature; and to carry out the overall mission of the Lafayette Police Department.
The Lafayette Police Department’s Criminal Investigation Division is subdivided into four sections:
- Adult Crimes
- Youth Services (Juvenile)
- Crime Scene
Adult Crimes are divided into two categories. There are those crimes of property in nature and crimes against persons. Investigators in both of these categories are assigned cases that occur throughout the city on a weekly basis. Each case has a thirty-day turn around, meaning that detectives must complete the case within a thirty-day period, unless the case needs further work.
Investigators conduct follow up investigations on specific crimes, thus allowing patrol officers to concentrate on other duties. They are also charged with disseminating information concerning dangerous suspects that have been discovered during the course of the investigation. Investigators must then prepare a detailed report in chronological order that explains the course of the investigation. This would include references to witnesses and the collection of evidence. This report is subsequently forwarded to the District Attorney’s office to assist the prosecutor in prosecuting those individuals who have been identified as suspects in cases.
Investigators with the Youth Services Section are responsible for following-up on all cases that involve victims or suspects under the age of 17. Just by pure numbers, the investigators handle a large volume of reports that are generated in the school system and throughout the City of Lafayette. Investigators attend specialized training for dealing with juveniles. Additionally, the Lafayette Police Department employs trained investigators to deal with the increasing number of cyber crimes.
Crime Scene Investigators are part of a joint unit shared with the Lafayette Parish Sheriff’s Office called, “Metro Crime Scene”. The investigators are on 24-hour call and report directly to the case detective when arriving on any scene. Once the case detective has briefed the Crime Scene Investigator, he or she begins to process the scene for vital evidence. This evidence is very instrumental in providing valuable information to the investigator. Crime Scene Investigators carry a complete evidence collection kit to include cameras, files, sketching equipment, fingerprint recovery tools, blood recovery materials, tweezers, scissors, boxes, bags, envelopes, tape, marking tools, evidence tags, and materials for lifting impressions (footprints, tire tracks).
The Lafayette Police Department currently has an agreement with the Lafayette Parish Sheriff’s Office, which governs the Metro Narcotics Unit. Investigators with both agencies work in both the city and rural areas to combat drug activities. Both agencies realize that the drug trade has no boundaries and it is incumbent upon law enforcement to work together in order to curb this ever increasing problem.
