Abstract

Forensic science integrates analytical chemistry, toxicology, and forensic medicine to generate objective scientific evidence for criminal investigations. The identification of pharmaceutical substances recovered during investigations is particularly important in medico-legal cases involving alleged illegal confinement, physical assault, coercion, or suspected drug administration. Gas Chromatography–Mass Spectrometry (GC–MS) is a widely established analytical technique for identifying volatile and semi-volatile organic compounds by combining efficient chromatographic separation with mass spectral characterization. Its sensitivity, selectivity, reproducibility, and compatibility with spectral databases, particularly the National Institute of Standards and Technology (NIST) Mass Spectral Library, make it valuable for forensic drug analysis. The present study demonstrates the application of GC–MS for the qualitative identification of active pharmaceutical ingredients (APIs) in seized therapeutic drug formulations recovered during the investigation of an alleged case involving prolonged illegal confinement and repeated physical assault. The analytical findings provide objective evidence regarding the chemical composition of the seized exhibits. Although chemical identification alone cannot establish drug misuse or criminal intent, its correlation with medico-legal findings and other corroborative evidence can strengthen forensic interpretation. The study focuses exclusively on qualitative API identification, without quantitative estimation or dosage verification.
