3年前,湖北钟祥市一所中学发生惊天特大投毒案,警方借助测谎仪确定了4名教师为犯罪嫌疑人,并且屈打成招。警方召开新闻发布会宣布案件告破,相关办案人员立功受奖。后在湖北省人大的不懈监督下,最终认定投毒犯罪证据不足,公安机关予以撤案,一起久拖不决的案件最终得以纠正。 Three years ago, a high school poisoning case occurred in a middle school in Zhongxiang City, Hubei Province. The police identified 4 teachers as suspects through the polygraph and performed the tactics. The police held a news conference to announce the case was solved and relevant investigators made meritorious awards. After the unremitting supervision by the Hubei Provincial People’s Congress, they eventually found that there was not enough evidence of drug crimes and that the public security organs had dismissed the case. Finally, a long-delayed case was eventually rectified.
