Can Latent Prints Reveal Lifestyle Information?

A study published this year in the journal Scientific Reports concludes that mass spectrometry imaging of chemical compounds in latent fingerprints can reveal important details about an individual's lifestyle.

The paper, written by Paige Hinners, Kelly C. O’Neill, and Young Jin Lee, explains, "Products applied, food and beverages consumed, and various environmental contacts will lead to a variety of chemical compounds in a latent fingerprint that can provide lifestyle information of an individual."

The study utilized matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) to study chemical compounds of various brands of bug sprays, food oils, alcohols, and citrus fruits.

Recovering Latent Fingerprints from Cadavers

IN A HOMICIDE CASE, the recovery of latent impressions from a body is just one more step that should be taken in the process of completing a thorough search. This article is directed at crime-scene technicians and the supervisors who support and direct evidence-recovery operations both in the field and in the controlled settings of the medical examiner’s office or the morgue under the coroner’s direction.
