Rebirth: A Female Forensic Doctor

"That's right, think about it, when you usually close this kind of window, do you just pull it and think it's locked? But some old windows have some problems. Many times they just close it.

That’s all, it can be opened directly from the outside.”

Qian Qianyi thought, this is indeed the case. There are several windows in their technical team that are like this. It depends on whether they can be locked. Sometimes they are closed but cannot be opened despite all their efforts.

If the murderer had jammed the window in advance to give the illusion that it was locked, in such a cold weather and the window was closed for a long time, Li Lanke would not play with it by pushing and pulling the window while taking a shower, so she always thought the window was locked.

, and didn’t even notice that someone had tampered with him.

This idea opened up a new way of solving the problem of the murderer entering the sealed bathroom, but there was still something that puzzled him.

"If the murderer really used this method to sneak into the deceased's bathroom on the night of the crime to commit murder, then why did he use sand to block the window slot instead of directly destroying the lock cylinder, or using other things to get stuck in the lock? Sand and soil have

Liquidity, if the window is closed with greater force, the sand will not be able to get stuck at all."

"I have thought about this, but it can be seen from the crime scene that the murderer is very careful and rigorous." Ye Fan shook his head and said: "Destroying the lock cylinder or using other things will leave traces and cannot be avoided by criminal investigation.

Technical means, but the use of sand is different. The window slots are prone to sand and dust, which is difficult to clean. Even if the police are at the scene, they will not easily notice it. Even if they notice it, they will only treat it as ordinary dust."

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

At the scene of the crime, she relied on her intuition and the principle of not missing any detail and asked the technical police to collect the sand in the window slots. Afterwards, to be honest, her mind was focused on the footprints on the exterior wall.

, as well as 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 did not place any doubt on these small grains of sand.

It wasn't until I was doing an autopsy on the car accident victim in the autopsy room and saw the sand on the blood sausage that I had a flash of inspiration, but unfortunately I couldn't grasp the key point. Later, Xiao Fang and Hua Ming talked about the window problem, and she suddenly caught the flash of inspiration.

, came all the way, and thought about the deduction carefully, the more she thought about it, the more likely it was that she felt it was very possible. When she saw the analysis report, she could almost verify her inference.

Qian Qian thought about it and nodded in agreement: "Indeed, not only will there be no traces, but if we use sand and soil, even if Li Lanke accidentally finds that the window is not locked, he will only think that the window has not been cleaned for too long and there is too much sand and dirt.

, will not raise any suspicion.”

Xia Dong exclaimed: "This murderer is really very thoughtful. First, he blocked the window with sand and soil in advance to make the window fake locked. On the night of the crime, he climbed down from the roof to the fourth floor, opened the window, and quietly

The sound entered the bathroom and killed the victim Li Lanke."

Qian Qian followed his words and added: "There must be a lot of sand and soil used to block the window slot. When the murderer left, he should have cleared away the sand and soil blocking the window slot. I remember the green belt under the bathroom window, that point

The sand was thrown down, just like water dripping into the sea, leaving no trace. Finally, the murderer left through the window. Without the soil stuck in the window slot, the window could be locked easily. When the police arrived, they saw a seal

The scene of the crime.”

Ye Fan nodded, but still maintained a rigorous attitude and said: "Whether the truth is as we inferred, further confirmation needs to be done."

Qian Qian: "I understand. It's too late today. Tomorrow I will take someone to pick up the soil from the green belt below the apartment building and come back for testing and composition comparison."

"You can analyze the sand and dust falling from the bathroom windows of other users on the same floor to see if only the sand and dust in the window slot of Li Lanke's bathroom contains humus." Ye Fan reminded again.

"Okay, I understand." Qian Qian made an OK gesture.

"I'll go talk to Team Chang, you guys get busy first." Ye Fan said and was about to leave the office.

"Wait a minute." Xia Dong stopped her in a hurry and said helplessly: "There's no rush at this moment. You haven't had dinner yet. Go back to the office to eat first."

Ye Fan originally wanted to say no, but with the insistence of the two of them, he went back to the forensic department office, ate the reheated lunch box in a few seconds, and then ran away again, making Xia Dong shake his head in amusement.

.

Team Chang is in the office, standing in front of the whiteboard, looking thoughtful.

A photo of Li Lanke was posted on the whiteboard, and a relationship analysis diagram was written in black oil pen. Among them, the names of Dai Lumao and his wife were circled with emphasis, and the pen in his hand was placed behind Liang Yunyue, with a big question mark.

Ye Fan knocked on the door and pushed the door open after receiving a reply saying "Please come in."

When Captain Chang saw Ye Fan coming, he immediately waved and said, "Ping Fei just came here. Your analysis makes sense. There seems to be something wrong with Liang Yunyue..."

"Team Chang, I just came from the technical team and discovered a problem that I ignored before." After Team Chang asked her to talk about Liang Yunyue's problem, Ye Fan said.

"Is there any new discovery made by Qian Qian?" Captain Chang's eyes lit up after hearing this. Ye Fan couldn't wait to come over to find him, so it must be a major discovery.

It has been several days since the incident, and the best golden period for solving the case is about to pass. Although the investigation into the interpersonal relationships of the deceased and the equipment used by the murderer has been investigated, the progress has not been great.

I didn't even know when I entered the bathroom, and I couldn't find anyone similar to the suspect in the surveillance. It can be said to be very tricky.

After reviewing the sand and soil in the window slot of the bathroom window, Ye Fan said: "We suspect that the murderer walked near Li Lanke's apartment and entered her apartment before killing him."

He was still thinking about how the murderer entered the bathroom. Unexpectedly, Ye Fan immediately brought him the good news. He was 100% convinced of Ye Fan's inference. Without any hesitation, he immediately opened the door of the office.

, called Gu Yuan, who was busy at her desk, and asked her to contact the property management of the community immediately to get the surveillance video of the community a few days before the incident.

When he returned to the office, Captain Chang's face was still filled with excitement. 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." Captain Chang laughed and subconsciously patted her shoulder with his broad and powerful palm. When he was about to pat her shoulder, he suddenly stopped and retracted his hand.

, he is an old man who is used to being rude, and the little girl is thin. If this palm slaps someone out, it will be a big sin.
