NATIONAL FORENSIC SCIENCE WEEK 🔬 Scientists in the Biology/DNA section of the laboratory screen items of evidence that are submitted to the Crime Laboratory Division from crime scenes to locate possible sources of DNA on these items. DNA profiles can be developed from a variety of sources including blood stains, semen, tissue, saliva, and hair roots. During DNA analysis, a DNA profile is developed from crime scene samples and known reference samples collected directly from persons of interest.

Today we’re wrapping up National Forensic Science Week by highlighting our DNA CODIS, DNA Forensics, and the Evidence Receiving units within the Louisiana State Police Crime Laboratory. Personnel within all of the units do an extraordinary job within their respective disciplines, see below for some of their recent accomplishments. The Louisiana State Police Crime Laboratory (LSPCL) recently became the first agency in the country to receive approval from the Federal Bureau of Investigation (FBI)
