Zhang Lan, female. A native of Suzhou, Jiangsu Province. He was only 25 years old when he was killed. During his lifetime, he was the deputy section chief of the Employment Section of the Labor and Employment Management Guidance Center under the Wuzhong District Human Resources and Social Security Bureau of Suzhou City. On the evening of November 6, 2010, Zhang Lan, who was deliberately drunk, was pushed into Xiaoshi Lake in Wuzhong District, Suzhou City by her 29-year-old husband Zhu Jiangtao in collusion with a third party, Zhu Lijun (born in 1983), causing her to drown on the spot. At the time of the incident, it was only more than half a year before the two officially got married. Afterwards, Zhu Jiangtao lied that his wife accidentally drowned after being drunk. It wasn't until he learned that the police would conduct an autopsy at the request of the deceased's family that he was forced to admit that he had planned the crime for a long time and visited the crime scene many times.
