TACIR draft urges regional crime‑lab expansion, rapid‑DNA authority at booking and digital‑forensics study

Summary
TACIR’s draft report recommends expanding TBI crime‑lab capacity across Tennessee’s three grand divisions, pursuing rapid‑DNA testing authority at booking stations, and supporting regional resource‑sharing; commissioners requested staff add a review of digital forensics capacity to the study.
Tennessee Advisory Commission on Intergovernmental Relations staff presented a draft report May 20 that urges expansion of crime‑lab capacity across the state, statutory changes to allow rapid DNA testing at booking stations, and strengthened regional partnerships to address backlogs and turnaround times.
Madison Thorne, the presenting researcher, said Tennessee has made progress reducing forensic backlogs but capacity constraints remain. The Tennessee Bureau of Investigation (TBI) increased scientist headcount but faces a primary constraint of laboratory workspace; TBI’s 2024 real‑estate strategic plan calls for expanding the Jackson lab, renovating and expanding Nashville, replacing the existing Knoxville lab with a larger facility equipped for firearms testing, and creating a smaller Chattanooga lab focused on drugs and toxicology. Thorne recommended the commission support capacity expansion in each grand division, prioritize overburdened disciplines (forensic chemistry and toxicology in Nashville), and pursue partnerships such as embedding a dedicated firearms analyst in Jackson to serve Memphis cases.
The draft also recommends the General Assembly amend statutes to permit rapid‑DNA technology at law‑enforcement booking stations so offender profiles can be uploaded quickly to CODIS. Thorne said other states have used rapid‑DNA to reduce similar backlogs. The draft advises TBI to pursue process‑improvement methods and resource‑sharing partnerships to train and assist local law enforcement.
Members questioned staffing and space constraints, the high turnaround times documented for firearms analyses and database entries, and whether digital forensics was within the study’s scope. Thorne said digital forensics is currently in a different TBI division and the draft did not make recommendations for it. Commissioner Representative Williams moved—and the commission agreed without objection—to direct staff to include digital‑forensics capacity and resource analyses in the study.
Why it matters: forensic turnaround times affect criminal cases, victims’ investigations, and public confidence; regional capacity expansion and statutory clarity on rapid‑DNA could reduce delays.
Next steps: staff will incorporate member input, include digital‑forensics analysis per the commission’s request, and refine cost and capacity estimates to inform potential funding requests.
