Forensic Investigations Using Thermography And Steam

Investigators are continuously searching for an optimal solution for finding concrete blood evidence in less-than-ideal circumstances. This is especially important when working with fabrics carrying diluted blood stains, which could easily be affected by the common practice of adding liquid luminol. Chemistry researchers at the University of South Carolina are investigating an alternative method for detecting and recording evidence of biological fluids. With the use of steam and infrared cameras from FLIR, the team was able to visualize blood with astonishing chemical contrast.
