The Use of DNA Just Gets More Interesting

Learning more about the use of DNA as a forensic tool.
 
Today I learned that DNA samples can be extracted from fingerprints/fingermarks. It makes perfect sense that “touch DNA” would be deposited at a crime scene through finger prints.
 
The results seem to vary depending on the surface where the print/mark was left and the duration of time the finger was pressed against the surface. Just the same, even if a fingerprint/fingermark is smudged, DNA might be extracted to help place a person at a crime scene.
 
I am waiting to hear back from a major DNA research firm to learn if DNA can be extracted from the material used to lift prints from a crime scene.
