Dr. Sheree Hughes-Stamm is testing a new way to collect DNA to better identify the victims of mass disasters.
To help identify victims after mass disasters, such as hurricanes, tsunamis, terrorist attacks, wars or acts of genocide, researchers at Sam Houston State University will investigate new techniques to preserve tissue samples and speed up the DNA identification process.
During natural and manmade disasters, forensic personnel often face adverse conditions, such as remote locations, intense heat, and the lack of electricity and resources. As a result, bodies may be left to decompose rapidly in the heat, creating a health hazard and also making genotyping more difficult as the DNA in those remains is also degrading.
“In these circumstances, forensic personnel may be faced with the task of identifying hundreds or even thousands of bodily remains in a very short period of time,” said Dr. Sheree Hughes-Stamm of the Department of Forensic Science. “Through improvement in the collection and processing of tissue samples for DNA analysis, we can identify more victims and help bring closure to those who would otherwise never know what happened to friends and family.”
