Ever wanted a firsthand look at what a forensic scientist does? In today’s video, you’ll meet three of our forensic scientists who analyze evidence in cases of homicides, assaults, hit-and-runs, fire investigations, burglaries and more, as part of the Trace Evidence Section of the DPS Crime Lab. Trace evidence analysis is based on the principle that when two objects come into contact with one another there will be a transfer of materials to the other. Our team of scientists is responsible for ex

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.

When it comes to illicit drug testing, the sensitivity of the analytical method is critical because scientists need to detect chemical compounds in very small amounts. In #BehindtheScience, Jen learns how forensic scientists at Boston University Medical School use multi-dimensional liquid chromatography, or 2D-LC.
