Determining the Donor Age Based on Raman Spectroscopy of a Bloodstain
Novel methodology helps forensic investigators determine victim's age from bloodstains.
Background:
In the absence of a body at a crime scene, forensic investigators must rely on whatever biological material is left behind to determine the sex, race, and age of perpetrators and victims. That often means analyzing stains like blood, sweat, and...
