Crime Scene Investigation Section

615-862-7826

The Crime Scene Investigation Section, formerly the Technical Investigations Section (TIS), is part of the Forensic Services Division under the Administrative Services Bureau. This section is staffed 24 hours a day by 3 different shifts. Every CSI investigator is trained in the documentation, collection and preservation of all manner of physical evidence. This can be (but is not limited to) a fingerprint, footprints, tool impressions, blood or semen, trace evidence (hair or fiber), or even tire impressions. These small, seemingly insignificant, pieces of evidence can be paramount to identifying a suspect and bringing them to justice. Many of the CSI investigators have attended specialized training schools from the FBI, TBI, ATF, DEA, and many universities throughout the southeastern United States. Additional specialized training has been studied in the disciplines of: chemically enhanced latent prints, specialized photography, blood stain pattern analysis, fingerprint comparison, digital photography, tire and foot print evidence, flight path analysis, practical homicide and death investigation, modern fingerprint development techniques and many more.

The CSI section is equipped with a complete mobile lab and support vehicles to respond to scenes. Evidence that cannot be processed in the field is brought to the Crime Scene Investigation Section’s latent evidence processing lab. The lab contains a wider variety of chemical processes that can be administered and there are several bays in which vehicles can be secured and processed at a later time. Because of the fragile nature of physical evidence some vehicles are brought here, out of the weather, and maintained in a controlled environment while waiting processing.
