New Technology Analyzes Fingerprints to Determine Alcohol and Substance Use

Unlike other types of evidence, fingerprints do

a

not “disappear” by any stretch of the imagination. As long as samples are stored properly, they can be used for further analysis years or even decades later. That is exactly what happened in this case. Scientists were able to determine whether or not individuals were male or female, as well as detect their alcohol and substance use. Oddly, this included the use of hair gel and even condoms, mind you, which is somewhat invasive when you think about it.

Although this new technology is not ready to be used in ongoing police investigations just yet, it will be in a matter of mere months. This will undoubtedly be extremely useful in taking a new look at so-called cold cases, which often remain unsolved for many years. To that end, researchers developed this technology together with the West Yorkshire police. It is not an inexpensive venture by any means, but the potential benefits clearly outweigh any cost associated with this new technology.
