Loughborough, United Kingdom – Analytical scientists at Loughborough University have achieved a groundbreaking discovery in forensic science. By analyzing gel-lifted fingerprints, they have successfully detected drug residue, specifically the fast-acting sleeping pill Zolpidem. This breakthrough has significant implications for solving cold cases and unsolved crimes related to drug-facilitated sexual assault and drink spiking.

Lead researcher Jim Reynolds and Ayoung Kim emphasized the importance of this discovery in providing valuable information from gel-lifted prints. Traditionally, detecting drugs from fingerprints has been challenging due to limitations such as degradation of drug residues and environmental interferences. However, their method, sfPESI-MS, allows for rapid separation of drug substances from the gel background, enabling more accurate drug detection.

The researchers successfully tested their technique by analyzing Zolpidem-laced fingerprints lifted from various surfaces in a laboratory setting. Moving forward, they aim to collaborate with law enforcement agencies to analyze stored gel-lifted prints and potentially identify other substances. Reynolds highlighted the versatility of their method, mentioning its potential application to substances beyond Zolpidem, such as explosives, paints, and dyes.

By linking chemical information to fingerprints, the researchers believe their method could aid in prosecutions and identify individuals involved in illicit activities. This innovative approach not only enhances forensic science capabilities but also has the potential to bring criminals to justice even in cold cases where additional information may be crucial. Through their research, Reynolds and Kim have opened up new possibilities for forensic analysis and crime solving.
