Case closed

In Jiangshan's drawer of the Criminal Police Brigade of Ningyuan City, there is a dossier and a closed case locked all year round.The reason was that one night six years ago, an informant who claimed to be placed in "Gumen" sent news that Wang Hua, the deputy director of the provincial department at that time, was on the death list of "Gumen", and the execution time was that night , the Provincial Department, with the mentality of preferring to believe in what is there, ordered the police to come to Wang Hua's home, only to find that Wang Hua had been killed, shot dead, and killed by one blow.

The pistol left at the scene was the gun of Zhang Qijiang, the former criminal policeman of the Ningyuan City Police Force, and the ballistic records are also traceable. It is absolutely certain that this gun killed Wang Hua.In addition, there were only Zhang Qijiang's fingerprints on the gun, and even the blood at the scene, except for the blood of the deceased, belonged to Zhang Qijiang. After the investigation by the provincial department, they joined forces with the Ningyuan City police to arrest Zhang Qijiang.

During the arrest, according to the situation described in the file, although Zhang Qijiang left a pistol at the murder scene, he kept resisting arrest and was suspected of assaulting the police.In the process of confrontation and dispute between the two sides, and it was difficult to arrest, he was shot dead by the deputy captain of the police force, and the case was closed.

Jiang Shan read the file over and over again. From the perspective of physical evidence, this case is almost perfect. The analysis of each clue has a large amount of evidence as the backbone. Jiang Shan has been thinking that the physical evidence is so perfect. What about the witnesses? Jiang Shan has been trying to find the witness who reported the crime again, the so-called informant planted in the 'Gu Men', but there has been no result.
