PRSAR Cold Case Unit
COLD CASES AND CLANDESTINE GRAVES
The PRSAR Cold Case Team is an elite group of volunteer professionals and scientists that has received education and training in the location of clandestine graves and investigation of cold cases. We have had the opportunity to train others at the national level in the detection of human remains. We utilize a high level multidisciplinary method to locate clandestine graves and shed light on cold cases.
WHAT WE DO:
We use state of the art techniques and tried and true methods to assist State, federal, local law enforcement and families in resolving cold cases and locating clandestine graves. Our methodology combines equipment, soil sampling, K9s trained and certified in the detection of the odor of Human Remains and our field training. Our team has been trained to recognize the unique botany and soil conditions present with clandestine graves.
We believe that the search for a clandestine or old grave requires a multi-discipline approach. We also have developed relationship with high level professionals in multiple disciplines including botanists, forensic anthropologists and others who are available to deploy with us to help resolve the most difficult cases.
IS THERE ANY GUARANTEE?
Because of the nature of cold cases, success cannot be guaranteed. However, our multi-discipline approach increases the chances of bringing closure to a case.
WHERE DO YOU SEARCH?
Our teams have been deployed from coast to coast throughout the United States, and we are ready to assist with searches involving land and water.
HOW MUCH DOES IT COST?
PRSAR always provides is search services for free. However, in some situations there are costs involved, usually to cover travel expenses. On complex searches we may partner with professionals in related fields who have their own fee schedules. Do not hesitate to contact us for more information.
DO YOU HELP FAMILIES OR ONLY LAW ENFORCEMENT?
PRSAR has always believed it is important to serve our community and bring closure to families and loved ones. While we welcome inquiries from the public or family, we will not deploy without notification to local law enforcement, and/or if doing so will interfere with an ongoing investigation.
DO YOU RECOVER THE REMAINS?
While our team members have been trained by federal law enforcement in the recovery of human remains we do not engage in the excavation of human remains. When we locate remains, we secure the scene, notify the authority having jurisdiction, and turn the scene over.
PRSAR is dedicated to helping locate loved ones who are missing. We use tried and true methods, well trained certified K9s and science and technology to locate remains.
Technologies which must be used in combination in order to successfully locate human remains may include:
- Odor analysis – very difficult to change – can’t really cover it up like fingerprints (wear gloves) or hair (wear a hat) or skin flakes (wear clothing)
A person’s odor has three (3) major components:
- Genetic based (part of major histo-compatibility complex – MHC, which cannot be changed) – microbial flora can be part of this.
- Odors created from a person’s diet
- Odors created from chemicals like perfumes/deodorants.
Analysis of odor at a scene can be accomplished by sniffing devices such as LABRADOR machine – (light-weight analyzer for buried remains and decomposition odor recognition) or collection of air samples and subsequent analysis with a gas chromatography/mass spectrometer. This type of analysis is currently NOT performed by crime laboratories.
- Piezoelectric properties of bone.
- Soil chemistry (Schiff’s, breakdown products of soft tissue and bone, pH, NRN, etc.)
- Soil Microbiology
- Geophysical methods (GPR, magnetometer, soil resistivity, thermal, hyperspectral)
- Canines (grave-detection dogs)
- Resonance frequency
Proposed Major Instrumentation:
- Gas chromatograph/mass spectrometer
- Hyperspectral imagery
- Thermal imagery
- Inductively coupled argon plasma spectroscopy (ICAP)
- High-performance liquid chromatography (HPLC)
- Ion chromatography (IC)
- Laser-induced breakdown spectroscopy (LIBS)
- Side scanning SONAR (for water searches)
