Abstract
A Comparative Analysis of Protein and Peroxidase Blood Enhancement Reagents Following Laundering and their Impact on DNA Recovery
Highlights
In criminal and forensic investigations, the connection between a perpetrator and a victim can often be the most condemnatory piece of evidence an investigator can find
When the protein reagents were tested, they revealed the greatest sensitivities (1:10) on the white polyester when compared to the peroxidase reagents, which only produced positive reactions on the laundered neat blood
The results of this study provide a valuable analysis of the persistence of DNA on various fabrics following laundering and treatment with commercially available blood enhancement reagents
Summary
In criminal and forensic investigations, the connection between a perpetrator and a victim can often be the most condemnatory piece of evidence an investigator can find. Blood evidence is common in cases of violent crime, and it is not unlikely that a suspect will try to destroy this evidence as its presence can serve as a link between an offender, a victim, and a crime. Often, these stains can be washed or laundered by perpetrators in hopes to clear away the evidence and diminish their association with a crime. Each category of staining method exploits different properties found within the composition of blood to produce reactions that can be indicative of the presence of blood
