The three of them looked a little uncomfortable to Du Dayong because they were confused by the question.
"Let you think about it."
"Team Du! The victim must know the criminal suspect, and the criminal suspect must have been to the victim's house more than once."
Fu Cheng grabbed the purple light and said excitedly.
"Yes! Only if you have been here and must know the victim, can you know which side the victim prefers to sleep on. This shows that the victim not only knows the suspect but is also very familiar with it."
Du Dayong confirmed Fu Cheng's words and shook the flashlight in his hand.
"Look here again. It's not that the victim didn't want to resist. Maybe the criminal suspect used a knife to hold the victim down. There is no hand support on the left side. What about the right side? Do you see where the dust has become thinner?"
"Captain Du! I know!"
Tang Wei spoke impatiently.
"There is obviously a push-like mark on the right side here, but if you don't shine it with this light, you won't notice it at all."
Du Dayong nodded.
"It shows that the victim must have suffered a lot of pain at that time. The traces of the push and push are already obvious, and the traces of the push and push are still upward."
After Du Dayong finished speaking, he asked Fu Cheng to turn off the purple light first.
"That's basically it here. Then let's see if there are any such traces in other places."
"Captain Du! There are benches and tables outside the partition curtain."
Li Xiaohui also felt like she had discovered a new continent.
The four people turned their attention to the tables and chairs on the other side of the curtain.
When the light continued to shine on the chair, Du Dayong knew that the chair here must have been moved during the inspection of the site, so it would not be of much significance.
When the light shone on the table, Du Dayong felt that this was the most rewarding place tonight.
Traces were left in three places.www.bǐqυgetν.℃ǒm
One is a rectangular mark, like the mark left by a box.
There is also a rectangular mark in another place, as if a slightly narrower rectangular box had been placed.
Another place looks like a place where a bag was left after falling asleep, and there are obvious drag marks.
Du Dayong quickly used a ruler to record the dimensions of all the prints.
These three traces left Du Dayong confused! Did the suspect bring something to eat? Or did he bring some box to put other things in? Could it be a knife?
I decided in my heart that when I go back tonight, I will first see what is in the stomach contents after the forensic autopsy.
After the four people inspected the tables, chairs and benches, they then went to the windows, but this time no marks were found.
"Tang Wei shines with the flashlight, Fu Cheng, Li Xiaohui, you two put the things away. Be careful not to touch things!"
After Du Dayong finished speaking, he took a flashlight and walked out.
Du Dayong went out and lit a cigarette. The cigarette butt was bright and dark. Tang Wei looked at Du Dayong outside the door and felt that Du Dayong was very powerful and mysterious.
Fu Cheng and Li Xiaohui also gained a lot tonight. This is much more exciting than sitting in the office. This is real learning.
Du Dayong was far from aware that just tonight and from then on at Qinglu Police Station, Fu Cheng would never leave him again, and whenever anyone asked, he would say that Du Dayong was his master.
It was already past 1:40 at night when we returned to the team.
Ning Hewei, Lu Yi, and Wang Jianghe didn't rest either. They had been waiting for Du Dayong and the others to come back.
Seeing Du Dayong and the others coming back, Ning and Wei went straight to greet them.
"Team Du! After investigation, we found that a car washer from a Huizhong Auto Repair Shop was missing four kilometers away from the crime scene. The grease extracted there was somewhat similar to the grease on the coins at the scene."
"After we questioned his colleagues, we found that the repairman left after resigning from his boss on March 16. When the Jiaodong police investigated there, he did not have an alibi, and when asked about his blood type, he
They also took out a blood donation certificate. The blood type on it was type A, so it was not within the scope of the screening. Later, the Jiaodong police investigated other people in the repair shop and found that none of them were suspected of committing the crime, so they did not focus on the repair shop as the focus of the secondary screening.
"
"I also think that the Dongjiao police had a very heavy workload at that time, and it takes us longer to check DNA now. This oversight is inevitable. Even if we were in that situation at the time, we would always want to catch the suspect as soon as possible.
, maybe we will also have similar negligence."
Ning Hewei was very objective and fair when talking.
"But when I went there this time, I found out that the car wash worker resigned just after passing the screening. I felt very strange. So I went to their boss and asked him to provide a copy of his ID card.
, after I came back, I checked the intranet, then intercepted the photo and went to the auto repair shop again. After careful identification by my colleagues in the factory, they said that there was an eight-point likeness, but it was definitely not him."
"Because the double eyelids are obvious on the ID card photo, but the person has obvious double eyelids. Only when his eyes are squinted will he look very similar."
"And he didn't have any means of communication. As for the evidence of his alibi, I also asked, but others heard him snoring in the car wash, but soon his colleagues reported that he also had a tape recorder."
Although Du Dayong did not believe that a car washer could be familiar with the victim, he had to find this person now. Only after he was found could he be confirmed or rejected.
Since this guy has assumed someone else's identity, the blood donation certificate must not be his.
He must not be a good person if he conceals his identity so deliberately.
