Rebirth of the open female forensic doctor

Chapter 713

"That's right, think about it, when you usually close this kind of window, don't you just pull it casually, and you will habitually think that it has been locked, but some old windows have some problems, and often you just close them That’s all, it can be opened directly from the outside.”

Qian Qianyi thought, this is indeed the case. There are a few windows in their technical team that are like this. Can they be locked or not?

If the murderer blocked the window in advance to make it look like it was locked, in such a severe cold weather, the window was closed for a long time, Li Lanke would not have nothing to do with pushing and pulling the window while taking a shower, so she always thought the window was locked , didn't even notice that someone had tampered with it.

This idea opened up new ideas for cracking the murderer's access to the sealed bathroom, but there was still something that puzzled him.

"If the murderer really used this method to sneak into the bathroom of the deceased and commit murder on the night of the crime, why did he use sand to block the window slot instead of directly destroying the lock cylinder, or use other things to get stuck in the lock? Liquidity, if you close the window with more force, the sand won’t get stuck at all.”

"I've thought about this too, but it can be seen from the scene of the crime that the murderer was very careful and rigorous." Ye Fan shook his head and said: "Destroying the lock gallbladder or using other things will leave traces and cannot escape criminal investigation." Technical means, but the use of sand and sand is different, the window slots are easy to fall sand and dust, and it is not easy to clean, even if the police are on the scene, they will not easily notice it, and even if they do, it will only be regarded as ordinary dust falling."

Speaking of this, Ye Fan had to admire how delicate the murderer's mind was.

At the scene of the crime, she relied on her intuition and the principle of not letting go of any subtleties, and asked the technical police to collect the sand and sand from the window slots. Afterwards, to be honest, her mind was all on the footprints on the outer wall , and the suspicious points on the deceased, I have long forgotten this.

Even though he was thinking hard about how the murderer could enter the seal, he didn't place any doubts on these small grains of sand.

It wasn’t until just now that an autopsy was performed on the deceased in a car accident in the autopsy room. When she saw the sand stained on the blood sausage, she had a flash of inspiration, but unfortunately she couldn’t grasp the key point. Later, Xiao Fang and Hua Ming talked about the window problem, and she suddenly grasped the inspiration point , along the way, thinking about the deduction, the more I thought about it, the more I felt it was very possible, and then I saw the analysis report, which could almost verify her inference.

Qian Qianyi thought, nodded in agreement, and said, "Indeed, not only will there be no traces, but if sand is used, even if Li Lanke accidentally finds that the windows are not locked, he will only think that the windows have not been cleaned for a long time, and too much sand has accumulated , will not be suspicious."

Xia Dong sighed: "The murderer's thoughts are really too meticulous. First, he blocked the windows with sand and soil in advance, so that the windows were in a false lock state. On the night of the crime, he climbed down from the top of the building to the fourth floor, opened the windows, and quietly opened the window." The voice entered the bathroom and killed the victim, Li Lanke."

Qian Qianshun added according to his words: "There must be a lot of sand and soil stuck in the window slot. When the murderer left, he should have cleared the sand stuck in the window slot. I remember the green belt under the bathroom window. The sand was thrown down, like water dripping into the sea, leaving no trace. In the end, the murderer left the window again. Without the mud stuck in the window slot, the window could be easily locked. When the police arrived, they saw that it was a sealed window. crime scene."

Ye Fan nodded, but still maintained a rigorous attitude: "Whether the truth is as we deduced, further confirmation is needed."

Qian Qian: "Understood. It's too late today. Tomorrow I will take someone to collect the soil from the green belt under the apartment building for inspection and composition comparison."

"You can take the sand and dust that fell from the bathroom windows of users on other floors on the same side and analyze it to see if it is only the window grooves in Li Lanke's bathroom that have humus." Ye Fan reminded again.

"Okay, I understand." Qian Qianbi gestured OK.

"I went to talk to Team Chang, you guys go ahead first." Ye Fan was about to leave the office as he said that.

"Wait." Xia Dong called to stop her who was in a hurry, and said helplessly: "There is no rush at this moment, you haven't eaten dinner yet, go back to the office for dinner first."

Ye Fan originally wanted to say no, but under the insistence of the two, he went back to the office of the forensic department, ate the reheated box lunch in two or three times, and then ran away again, making Xia Dong laugh and shake his head .

Team Chang is in the office, standing in front of the whiteboard, with a pensive look on his face.

A photo of Li Lanke was pasted on the whiteboard, and a relationship analysis diagram was written with a black oil pen. Among them, the names of Dai Lumao and his wife were emphatically drawn in a circle, and the pen in his hand was on the back of Liang Yunyue, with a big question mark added.

Ye Fan knocked on the door, and only pushed in after getting a reply to come in.

The Chang team saw Ye Fan coming, and immediately waved: "Ping Fei just came over, your analysis makes sense, this Liang Yunyue seems to be really problematic..."

"Chang Que, I just came from the technical team and found a problem that I had overlooked before." After Chang Que pulled her to talk about Liang Yunyue's question, Ye Fan said.

"Is there a new discovery from Qian Qian?" Chang Dui listened, and his eyes lit up. Ye Fan couldn't wait to come to him, so it must be a major discovery.

It has been a few days since the incident, and the best golden period for solving the case is coming to an end. Although the deceased's interpersonal relationship and the equipment used by the murderer to climb have the direction of investigation, but the progress is not great. How did they connect the murderer? It can be said that it is very tricky to enter the bathroom without knowing it and not being able to find a similar suspect in the surveillance.

After Ye Fan talked about the sand and sand in the window slot of the bathroom window, he said: "We suspect that the murderer stepped on a spot near Li Lanke's apartment and entered her apartment before the murder."

He was still thinking about the way the murderer got into the bathroom, but he didn't expect Ye Fan to send him the good news immediately. He was 100% convinced of Ye Fan's deduction, and immediately opened the door of the office without any hesitation. Called Gu Yuan, who was busy at the desk, and asked her to contact the community property immediately to get the surveillance video of the community a few days before the incident.

When he turned back to the office, Chang Que's face was still full of excitement, and he had even gradually developed a belief that as long as Ye Fan was around, there would be no case that their criminal investigation team could not solve.

"Ye Fan, you are the lucky star of our criminal investigation team, haha." Chang Dui laughed and subconsciously patted her shoulder with his broad and powerful palm, stopped suddenly when he was about to pat her shoulder, and withdrew his hand embarrassingly Well, he is used to being rough and rude, and the little girl has a thin body. If he slaps someone badly with this slap, it will be a serious crime.
