How did the police solve the murder case with incomplete fingerprints?

The police also have different kinds of police. The police must be in charge of civil disputes. In order to trace the real murderer, prevent the suspect from getting away with it, and give justice to the victim. On September 27th, 2008, a criminal case occurred. At that time, the owner of a grocery store in xingning city died mysteriously in the store. This matter has never been solved by the police. Now ten years later, the police finally found the suspect through half a fingerprint. Mr. Wu, the family member of the deceased, told the police that when his father fell to the ground, he thought that he was sick and would die if he hit a hard object.

So he wants to invite his relatives and friends to hold a funeral for his father. When he was sorting out his father's affairs, he found that his father had an obvious wound on his head, which was obviously hit in the head and died. Knowing this kind of thing, I immediately called the police and asked the police to investigate the case. It was not until the whole family was saddened by the death of their father that they knew it was man-made. The police immediately launched an investigation, but at that time, the family thought that his father was tripped and hit by a heavy object before his death, so he cleaned up the blood when dealing with the aftermath.

The scene is clean, without any trace. For the police, it is difficult to handle the case, the scene is destroyed, and the investigation work becomes very difficult. During the investigation, the police found that there were no witnesses and no surveillance videos that night. How can they find the prisoner without evidence? But the careful police still found a broken fingerprint with suspicious blood on it.

With this clue, the police immediately investigated the family members at the scene. More than a decade ago, the police have been visiting everywhere, collecting clues of the deceased before his death, and also collecting many fingerprints, trying to find the criminal suspect at that time. After a long investigation, it was found that the deceased did not have any social disputes at all, and he did not have any grievances with others at ordinary times. All the fingerprints were compared, and none of them matched.

At that time, the police fell into self-doubt and the investigation direction was inaccurate. In recent years, the public security bureau has not given up the investigation, but also conducted investigations nationwide. On 20/2, Kloc-0 found a fingerprint of Wu Mou, which was very similar to the incomplete fingerprint at the scene, so the police launched a detailed investigation on him. After a comparative investigation by experts, it is confirmed that this Wu Mou is completely consistent with the fingerprints at the scene. The police found the suspect through fingerprints.
