Ground Penetrating Radar

Until recently, ground penetrating radar has specifically been used to find objects underground such as electrical lines, water lines, sewer lines, and the like. Forensic Ground Penetrating Radar is now a useful tool in the field of forensics and police investigations. With the ability to scan to great depths, ground penetrating radar systems are capable of locating items such as buried drugs, weapons, and even bodies. Most importantly, evidence can be located in an area of interest without causing any damage to it.

A few missing persons cases have even been solved utilizing ground penetrating radar. When tips are received by police that there is a possibility of an individual being buried in an area, a GPR system is brought in.

If anomalies are found by Steel City NDT LLC within the subsurface, it is enough for the police to obtain a police warrant to dig at those locations. In the famous case of the search for Alabama high school graduate Natalee Holloway, GPR was brought in when a tip was received that she was possibly buried along a beach in Aruba. A news article on this can be seen here:

Applications GPR can be utilized on for forensic investigations by Steel City NDT LLC include, but are not limited to:

  • Soil
  • Asphalt
  • Pavement
  • Concrete
  • Walls

Aside from manual excavation, the most important thing to remember is that most pieces of evidence located within the subsurface are not able to be found via metal detectors or magnetometers. This includes, but is not limited to, buried bodies, explosives, disturbed soil, tunnels or chambers, and buried caches of drugs or money. If a general area of concern is tipped off or located, Steel City NDT LLC is capable of identifying any disturbances which may solve the next big case.
