I yelled many times and no one answered. Xiaozhu, who felt strange, called the landlord and the neighbors nearby. Several people broke the door open. As soon as he entered the door, he saw the landlady lying on the bed with blood on her head.
After receiving the alarm, the police immediately rushed to the scene to investigate, only to see blood splashed all over the head of the bed. Although the scene of the crime was turned over in many places, some of the cash was not taken away. The police speculated that the murderer may have awakened Zhang in the process of burglary. The murderer then killed Zhang and fled the scene.
For the sake of justice, generations of criminal investigation police persevere and relay the investigation office. Over the years, through continuous efforts, although the police have obtained some clues, but has not found a substantive breakthrough.
Since the launch of the 2020 cloud sword - long standing homicide cases campaign this year, Yiwu Public Security Bureau has sorted out the on-the-spot evidence of unsolved cases once again, led by the criminal investigation team, and comprehensively used the latest criminal science and technology to tackle the remaining long-standing homicide cases.

In one group, the squadron of major cases comprehensively sorted out and analyzed the cases, found out the omissions and supplemented the doubts. When the similar cases happened in the surrounding counties and cities of Yiwu in those years, a suspicious figure came into the sight of the police.
