description | In order to investigate the information for effective detection and developing of latent fingerprints, we identified fatty acids composition of latent fingerprints on non-porous evidence surface and the chemical changes of latent fingerprint residue after print deposition during 7 months. Fingerprints from eight Korean male donors (aged 29-50 years) and one female donor (aged 36 years) were collected. All fingerprints were found to contain lauric acid (C12:0), myristic acid (C14:0), palmitic acid (C16:0), stearic acid (C18:0), elaidic acid (C18:1n9t), oleic acid (C18:1n9c), linoleic acid (C18:2n6c), arachidic acid (C20:0), linolenic acid (C18:3n3), erucic acid (C22:1n9) and docosadienoic acid (C22:2) and primarily palmitic acid (35.45-48.37%), oleic acid (14.84-28.49%), stearic acid (9.71-24.96%) and linoleic acid (7.68-18.8%) occupied 75% of total fatty acids. When the fingerprints were deposited at dark room for 7 months, total fatty acids components decreased about 12-25%. It can be explained that significant degradation of long-chain fatty acids such as elaidic acid (C18:1n9t), arachidic acid (C20:0), linolenic acid (C18:3n3), erucic acid (C22:1n9), and docosadienoic acid (C22:2) resulted in the generation of myristic acid (C14:0), myristoleic acid (C14:1) and pentadecanoic acid (C15:0). 사건현장에 잔류하는 잠재지문의 효과적인 탐색 및 감식을 위한 자료를 얻고자 비다공성 증거물에 잔류된 잠재지문의 지방산 조성분석을 실시하고 7개월간의 지문유류에 따른 조성 변화에 대하여 알아보고자 하였다. 지문시료는 한국인 29-50 세 남성 8인과 여성(36 세) 1명으로부터 제공받았다. 모든 지문에서는 lauric acid (C12:0), myristic acid (C14:0), palmitic acid (C16:0), stearic acid (C18:0), elaidic acid (C18:1n9t), oleic acid (C18:1n9c), linoleic acid (C18:2n6c), arachidic acid (C20:0), linolenic acid (C18:3n3), erucic acid (C22:1n9)와 docosadienoic acid (C22:2)의 11종의 지방산이 검출됨을 확인하였고, palmitic acid (35.45-48.37%), oleic acid (14.84-28.49%), stearic acid (9.71-24.96%)와 linoleic acid (7.68-18.85%)가 확인된 지방산조성의 75%이상을 차지하여 주요 구성성분임을 알 수 있었다. 또한 7개월간 온도 $20-25^{\circ}C$, 습도 40-50%의암실환경에서의장기간유류에따라총지방산의함량이 12-25% 감소하였으며, 이는 elaidic acid (C18:1n9t), arachidic acid (C20:0), linolenic acid (C18:3n3), erucic acid (C22:1n9), docosadienoic acid (C22:2)의 장쇄지방산들의 소실과 단쇄지방산인 myristic acid (C14:0), myristoleic acid (C14:1), pentadecanoic acid (C15:0)의 생성에 따른 결과임을 확인하였다. |
