摘　　要：目的探索可在受害人皮肤表面显现嫌疑人触摸痕迹并检验其微量DNA的方法。方法将“靶向显现试剂”均匀喷洒于尸体裸露皮肤处,而后用“靶向生物痕迹发现仪”观测,对发现的荧光斑迹,以合适力度用棉签擦拭并进行DNA提取检验。结果对在死者颈部及手臂处发现的若干指印,经提取其所含DNA并检验,检出混合基因型,其中包含嫌疑人的DNA。结论尸体体表痕迹的发现及其DNA检验有助于挖掘更多的案件信息,有利于犯罪现场重建。Objective To explore an approach for discovering the suspect’s trace left on victim’s skin where to have the related DNA be extracted and tested.Methods Onto the exposed places of case-corpse’s skin was sprayed the biological evidence-targeting reagent.Afterwards,the biological evidence-targeting device was adopted to observe the fluorescenceemitting spots where to wipe with swabs from which DNA was extracted and tested.Results On the forearm and neck of the deceased were developed latent fingerprints from which mixed DNA STR profile was tested with the suspect’s being enclosed.Conclusion Discovery of biological touch trace,e.g.,fingerprint,on corpse surface and having the relevant DNA tested can make more information revealed about the involving case,hence helpful to reconstruct the crime scene.
