What is Forensic Investigation Support and what it includes

Forensic Investigation Support combines advanced geophysical survey methods with experienced data interpretation to assist in the search for subsurface forensic evidence. Rather than relying solely on intrusive investigation methods, Kiwa T2 applies non-destructive technologies to quickly assess large areas and identify locations that warrant closer examination.

Geophysical instruments measure contrasts in subsurface materials and conditions, allowing investigators to detect anomalies that may be associated with buried objects, disturbed ground, containers, voids, or other features of interest. Technologies such as Ground Penetrating Radar (GPR) and multi-channel GPR techniques may be deployed depending on site conditions and project objectives. These technologies are commonly used to image subsurface conditions and identify anomalies without disturbing the ground.

Who is it for?

This service by Kiwa T2 is intended for law enforcement agencies, forensic investigators, search and recovery teams, legal authorities, and government agencies. These organizations are typically involved in evidence searches, missing person investigations, unmarked burial investigations, land management decisions, and other activities requiring the identification of subsurface anomalies without immediate excavation.

Benefits of Forensic Investigation Support

  • Rapidly screen large search areas to improve investigation efficiency. 
  • Reduce the extent of intrusive excavation and ground disturbance. 
  • Identify subsurface anomalies that may warrant additional investigation. 
  • Support evidence-based decision making through objective geophysical data. 
  • Improve resource allocation by prioritizing search locations. 
  • Provide detailed mapping and documentation for investigative teams.

Frequently asked questions

What types of investigations can this service support?

The service can support forensic searches, missing person investigations, unmarked burial investigations, evidence location efforts, historical site assessments, and other projects requiring non-destructive subsurface investigations.

What geophysical technologies are commonly used?

Depending on site conditions, Kiwa T2 may use Ground Penetrating Radar (GPR), multi-channel GPR, and other geophysical technologies to investigate subsurface conditions. 

Can geophysics confirm the presence of evidence?

Geophysical surveys identify subsurface anomalies and areas of interest. Follow-up investigation is typically required to determine the exact nature of detected features.

Will the investigation disturb the ground?

Most geophysical survey methods are non-invasive and allow large areas to be investigated without excavation or significant disturbance to the site.

How large an area can be investigated?

Survey coverage depends on site access, terrain, vegetation, and project requirements. Geophysical methods are particularly valuable for rapidly assessing large areas and identifying priority investigation zones.

Are geophysical surveys suitable for sensitive sites?

Yes. Because the methods are typically non-destructive, they are often used in areas where minimizing disturbance is an important consideration, including culturally and historically sensitive sites.
