Question 1

What forensic disciplines does the mobile forensic lab support?

Accepted Answer

Standard configuration supports DNA profiling (autosomal STR for individual identification, Y-STR for paternity or male-lineage analysis, mitochondrial sequencing for degraded samples), toxicology (drug screening and confirmation in blood, urine, tissue), trace evidence (fibre comparison, hair examination, glass fragment analysis), and latent fingerprint development. Extended configurations add digital forensics (mobile device extraction, computer evidence processing), forensic ballistics (firearm comparison microscopy, tool mark examination), and forensic document examination.

Question 2

How does the mobile forensic lab differ from the modular forensic lab unit?

Accepted Answer

Mobile forensic lab trailer is road-deployable on chassis — drives to field sites for rapid forensic deployment, typical use case is crime scene support, mass grave investigation, or field forensic campaigns. Modular forensic lab unit is permanent or semi-permanent installation — larger workspace and equipment capacity, suited to regional forensic laboratories and sustained operations. Many forensic services operate both: modular for regional laboratory bases, mobile for rapid field deployment.

Question 3

How is chain of custody maintained in the mobile forensic lab?

Accepted Answer

Chain-of-custody features include: secure evidence reception with electronic logging using bar codes or RFID, biometric or token access to evidence storage, video surveillance through evidence handling areas, tamper-evident evidence packaging requirements, electronic case management system integration, and audit logging of all evidence movements. Physical custody of evidence is tracked from scene through laboratory through court presentation with every transfer recorded.

Question 4

Can the mobile forensic lab process DNA evidence?

Accepted Answer

Yes — DNA processing is a primary capability. DNA workflow includes sample extraction (from buccal swabs, blood, tissue, trace biological evidence), PCR amplification in the separated pre-PCR zone, capillary electrophoresis in the post-PCR zone for STR profiling, and result analysis through STR profiling software. Contamination control is critical — separation of pre-PCR and post-PCR zones, dedicated reagents and consumables for each zone, and UV decontamination cycles maintain sample integrity.

Question 5

What is the deployment time for the mobile forensic lab?

Accepted Answer

From dispatch to operational readiness is typically 24-48 hours depending on transport distance to the deployment site. On-site setup (trailer positioning, utility connection, instrument calibration verification, contamination control verification) takes 4-8 hours for the first operational day; subsequent days operate on routine laboratory workflow. For crime scene forensic support, the trailer typically deploys in the initial response window supporting on-scene evidence processing and preliminary analysis.
