Du Dayong looked at the autopsy report. There were many clues, but not many that were useful.
The male deceased also took sleeping pills before his death, which means that the murderer must have known or was not a stranger to the deceased, but he could have strangled him directly. Why did he use sleeping pills to smash him with an ax after taking sleeping pills? Not only did he smash it, why did he continue to use an axe?
Cut off the carotid artery of the deceased?
After the deceased was already dead, he could have smashed his face with an axe, so why would he use a paper knife to perform such inhumane cuts? How much hatred does this show towards the deceased?
It is not like the female deceased should be buried together with the male deceased. Du Dayong felt that it was very conflicting.
The female deceased was obviously tied up, sexually assaulted, and her brain was hit with a brick or other object, causing her to fall into coma and then strangled to death. Finally, her face was smashed with a brick or other hard object, and the male deceased was in a state of death.
Including the motive for the crime and the murder weapon are completely different.
But why were these two people buried together? Du Dayong felt a little weird.
Could it be that two murderers committed the crime at the same time? Du Dayong quickly denied it! Because the forensic doctor concluded from the hair follicles of the female deceased that there were traces of grabbing and dragging the hair, but the male deceased's hair was not long, but there was no trace at all.
The time of death and the way they were treated were completely wrong for the two deceased persons. Even if the murderer's criminal methods were upgraded, the obvious characteristics of the murderer's crime would not be gone.
The female deceased was more likely to have committed a random crime, and the male deceased was more likely to have committed a premeditated crime, but why were they buried together?
Du Dayong was really puzzled at this moment!
The whole murder case seems a bit strange, but there seems to be some connection.
The fingerprints of the male deceased and the female deceased were compared, but there was no match, indicating that neither of the two victims had a criminal record.
Then through the investigation of missing persons, it was found that there are currently no missing persons in Qinglu City who meet the criteria.
If a nationwide investigation were to be carried out, the workload would be enormous, and it is currently impossible to conduct a full investigation.
But it is impossible for the deceased to reach Qinglu through a long period of travel!
Du Dayong thought that the deceased should be almost the missing person from the prefecture-level city near Qinglu, but after comparison, none of them matched!
Because the body is highly decomposed, forensic doctors are now actively looking for obvious birthmarks or other landmarks on the body for confirmation.
So now the only person who is useful to Du Dayong is the person mentioned in Zhang Doudou's confession, and the portrait artist is still actively correcting it.
But Du Dayong will not stay in the office to solve the case!
At least the person Zhang Doudou provided must be a local or someone familiar with Xiaohe Village.
Du Dayong asked Zhang Doudou again to determine how similar the existing portrait was, and Zhang Doudou said it was about eight points.
So Du Dayong made dozens of copies and reported them to Wu Zhengping, asking for a reward.
After an afternoon of visiting and posting, everyone in the three groups was exhausted.
But no one said a word. When they returned to the team, they were sorting out the news they had received.
The captain of the First Squadron is called Zhao Changqing. He is thirty-seven or eighteen years old, and he has been very busy leading the First Squadron these days.
Since the city bureau is launching a summer crackdown, only the captain and two criminal policemen from the No. 1 Squadron are here to help.
Du Dayong came back every day and started combing through all the information, trying to find some useful information, but he really couldn't find it.
On the third day after the reward notice was posted, the portraitist led Zhang Doudou over.
Because of this portrait, Zhang Doudou said that it was at least 95% like it.
So the next day, all the bounties that were immediately posted changed their avatars and were posted again.
The bounty reward has also been increased from the initial five thousand to ten thousand.
The day after the second reward notice was posted, the first reporting phone call finally came in.
The entire three groups plus the first squadron immediately became excited. Everyone in the team gathered around the phone and looked at Du Dayong eagerly.
