Detectives assist patrol deputies in investigations. Once a uniformed deputy takes a report, detectives may begin a follow-up investigation. The Criminal Investigation Division is responsible for processing and cataloging evidence at crime scenes. They interview victims, witnesses, and suspects as well as prepare affidavits for arrest warrants and search warrants along with other various investigation related duties.
In 2013, detectives investigated four homicides making an arrest or arrests in each case. The solved murder cases are a direct result of the efforts of detectives in collecting and corroborating evidence and submitting DNA evidence from the crime scenes to the Acadiana Crime Laboratory for analysis.
Information on suspected criminal activities or current investigations may be sent to detectives at firstname.lastname@example.org or by contacting the Criminal Investigation Division at 337-828-1960 or 985-384-1622.
