这是一起全国罕见的奇案:案件当事人特殊,死者和凶手包括知情人都是聋哑人;作案手段特殊,聋哑人在异地利用“手机短信”雇佣聋哑人杀人;破案难度大,这些聋哑人都具有反侦查能力;聋哑人作案后全国流窜且不与外界人员接触,警方的调查访问对象也都是聋哑人。“哑人不开口,神仙难下手”。警方是如何与聋哑人案犯斗智斗勇,最终侦破“聋哑人迷案”的? This is a rare case of rare national case: the parties are special, the deceased and the murderer, including insiders are deaf and mute; crime means are special, deaf mute in different places to use “SMS” hired deaf mute; These deaf and mute people all have anti-detection capabilities. After deaf and mute people migrated across the country without any contact with outsiders even after committing crimes, police investigations were all deaf and mute people. “Mute does not speak, immortal hard hands”. How does the police fight the deaf-mute case and eventually detect the “deaf-mute case”?
