Forensic Fingerprint Intelligence Analysis: Technology Status and Prospect
摘要
Abstract
Fingerprint has been well-known as "one most important forensic evidence" for a long time.Besides the ability to identify an individual with its patterns,fingerprint contains numerous key information about a suspect.Demonstrably,the secretion and deposition of chemical components in fingerprint can be used to analyze the characteristics of a suspect.The detection of substances in fingerprint has therewith aroused great interests of criminal investigators and forensic researchers since it facilitates narrowing the scope of criminal suspects.For example,in fighting against the violent crimes,the detection of ammunition and explosive residues in fingerprint can greatly help the investigation of the cases;the identification of drug residues and metabolites in fingerprint can provide information about whether the suspect uses drugs,smokes or is undergoing a disease treatment.The detection of food residues and cosmetic components in fingerprint can assist in inferring a suspect about his/her certain life habit.This paper reviews the researches on the detection of fingerprint from five aspects relating to drug users,smokers,explosive carriers,sexual assaulters and gender.The expounding mainly involves with the detection methods about biochemical choices (e.g.,combining antibodies with fluorescent materials),biological assays (e.g.,competitive enzyme immunoassay),instrumental analysis handlings (e.g.,mass spectrometry,infrared spectrum analysis) and statistical ways.Based on the established researches and the problems confronted in the actual criminal investigation,three prospective development directions (of endogenous/exogenous substance and the age of fingerprint) are proposed for the forensic fingerprint intelligence analysis.Anyway,obtainment of more case information is always desirable for fingerprint identification so as to portray a suspect accurately further,and promote the role of forensic science in crime investigation and other legal processes as ably as possible.关键词
