摘　　要：犯罪嫌疑人在实施故意杀人等严重恶性犯罪的时候通常会选用以火药为动力的枪支。为了严厉打击非法持有枪支的行为,国家相关规定对此类枪支的持有行为均有较严厉的处罚规定。2016年上半年天津北辰区的两起涉枪杀人案件中,现场勘查人员在死者体内均发现了钢珠。笔者通过侦查实验,分析犯罪嫌疑人使用的作案工具为带气瓶的以气体为动力的长型枪支,从而为案件侦破提供了线索,并根据此案提出了关于非法持有、私藏枪支定罪处罚的意见建议。Firearms are often chosen by criminal suspects to commit severely vicious crimes among which the deliberatehomicides sometimes occur.In order to crack down the crimes involved with illegal possession of guns,the State stipulatedrelevant provisions to sternly punish the conducts of illegal possession of guns.Two gun-involving homicidal cases happenedin Beichen district of Tianjin during the2016-year first half,leaving the steel balls found in the dead bodies.Through theinvestigative simulating experiment,the criminal tool was judged to be a long air gun that has a gas cylinder,providing a clueto solve the cases.Accordingly,some suggestions and opinions are thereby made for conviction and punishment against theillegal possession and/or secret concealment of a gun.
