Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 498 Floor Mats and Slippers

Before entering the room, Lu Chuan put on a full set of field survey equipment.

Because Wang Feng did not have a particularly harmonious relationship with his parents after he was fired for undercover work last year, so although he was missing for three days, his parents did not know that he was missing. If Yang Lin hadn't called them to report the case, there would have been Maybe they don't know Wang Feng's current situation.

Therefore, his parents have never been in the room. The situation in the room now should be the first scene after Wang Feng disappeared.

"Brother Hui, wait a moment. I'll scan your fingerprints first."

Putting on his gloves, Lu Chuan took out a portable ultraviolet lighting lamp.

Although it is not particularly accurate to use ultraviolet lighting to check fingerprints during the day, fortunately, Lu Chuan only needs to find the fingerprints now, and does not need to collect them now.

Zhang Hui and Yang Lin did not enter the room when Lu Chuan was doing the spot survey.

"Yang Lin, you follow Lu Chuan here to do the spot survey, while I walk around upstairs and downstairs."

Huijiayuan community was built relatively early, and it is a welfare house for the work unit. Most of the neighbors are colleagues from Wang Feng's father's work unit.

Zhang Hui wanted to do some research first, and get a rough idea of ​​Wang Feng's living conditions in the past year or so with his neighbors upstairs and downstairs.

dong dong dong.

The building where Wang Feng lives has two rooms on one floor, and there is a neighbor across the door.

Soon the door opened, revealing a middle-aged woman in her 50s.

"you are?"

The middle-aged woman is not tall, about 1.6 meters tall, slightly fat, and wears home clothes. The woman is more safety-conscious. There is an anti-theft lock on the opened security door, but not all of it is opened.

"Hello, I am Zhang Hui, a police officer from the Huaguang Street Police Station. Here is my ID. I want to know something about you."

The woman glanced at the opposite door. Zhang Hui and Lu Chuan were not wearing police uniforms, but Yang Lin was wearing uniforms. With the ID in Zhang Hui's hand, the woman hurriedly opened the security door.

"Oh, hello, Officer Zhang, please come in."

Zhang Hui nodded and thanked: "Do you need to change shoes?"

"No, no, please sit down and I'll pour you a cup of tea."

The woman was very enthusiastic. After confirming the identity of police officer Zhang Hui, her expression was very relaxed.

"Sister, don't be busy. I understand the situation and will leave immediately."

After a while, the woman sat on the sofa: "What do you want to ask Xiao Wang opposite?"

Hearing the name Xiao Wang, Zhang Hui's heart moved: "Sister, are you familiar with me?"

"I can't say we are very familiar with each other. His father and I are colleagues, but I am a worker and retired when I was 50."

Zhang Hui nodded. There are also women who retire at the age of 50 in the Criminal Investigation Detachment, but the proportion is relatively small. Generally, those who work in the field will retire at the age of 50, but those who work in the back office and management will not retire until the age of 55, while men uniformly retire at the age of 60. .

"Oh, by the way, do you have anything to do with him? I haven't seen him for several days."

"Wang Feng's parents reported him missing. He has not contacted his family for three days."

"Missing?"

The woman looked slightly shocked, then sighed: "Well, Wang Feng turned out to be a good boy. I remember that he studied very well when he was in school, and he was admitted to the Public Security University."

"But I don't know why it seemed like I was fired later?"

"In recent times, some unscrupulous people have been coming to his house. We are saying that this child is a bad student."

"Why did you disappear?"

Zhang Hui didn't say much, and then asked about Wang Feng's disappearance: "Sister, it was probably after 11 o'clock in the evening three days ago. Did you hear any unusual sounds or situations on the other side?" "Three days ago? It seems like that. There are no special circumstances..."

When Zhang Hui visited and investigated, Lu Chuan made some progress in some existing surveys.

Wang Feng's home is relatively tidy, unlike other bachelors whose homes are messy.

This house is about [-] square meters and is a typical clover house. After entering the door, there is the living room on the left, the dining room on the right, connected to the kitchen, and the bathroom and bedrooms on the left and right opposite.

Lu Chuan first roughly scanned the door and found a lot of fingerprints, but according to preliminary analysis, it should be Wang Feng's fingerprints alone.

The floor is clean and tidy, and there is a floor mat at the door after entering the room.

This is the area that Lu Chuan carried out an important inspection.

"Kawako, what's there to check on the floor mat?"

This was the first time that Yang Lin followed Lu Chuan to watch him do a live survey, and there were some things that he didn't understand very clearly.

According to the style of police handling cases at the police station, just open the door and go in. If there is anything that can be found inside, it will be found. If not, it will be gone.

Lu Chuan shook his head and pointed to some dirt and dust on the floor mat.

"Wang Feng ordered a mango ice cream that night. He is allergic to mangoes, which means there might be another person in the house at that time."

Yang Lin nodded. This was what he found when he checked Wang Feng's call records.

"We assume that the person in Wang Feng's house at that time was related to his disappearance, so where did he come from?"

"The first step for the other party to enter Wang Feng's home is to leave traces on the floor mat. I will collect some soil and dust on it to see if I can go back and do some trace evidence analysis. If the other party really has something to do with Wang Feng, If it is related, then the place where Wang Feng was imprisoned may be where the other party came from, which may be helpful to us in solving the case later."

Yang Lin said oh, a bit enlightened.

Of course, Lu Chuan and the other three had just discussed that cup of mango ice cream on the way here.

Wang Feng ordered a cup of mango ice cream through takeout in the middle of the night, or someone in his room wanted to eat it, so he ordered a cup of mango ice cream.

Another possibility is that Wang Feng ordered the mango ice cream on purpose?
Lu Chuan, Yang Lin and others knew that he was allergic to mangoes. Is it possible that this was a clue intentionally left by Wang Feng?
But what the specific situation is, Lu Chuan and others still don't know, but this clue should be an important clue.

About half an hour later, Lu Chuan finished collecting the soil and dust on the floor mat.

Then he lay down on the ground and looked to see if there were any remaining footprints on the floor tiles.

"Lao Lu, there are two pairs of slippers next to here. I think the other person must have changed his shoes when he came in."

Yang Lin pointed to the two pairs of slippers placed untidyly on the edge of the floor mat.

Of course Lu Chuan also noticed this: "The toes of the two pairs of slippers are facing the door, which means that the other party should have changed his slippers and left."

Under normal circumstances, normal people rarely turn around to take off their shoes and rearrange them so that their toes face the direction of the room.

What Lu Chuan had just observed was whether the other party might wear his own shoes and leave marks on the floor tiles.

Because compared to the marks left by slippers, the data results obtained by using the footprints left by normal outdoor shoes for footprint identification analysis are relatively more accurate.

It's a pity that the other party had changed his shoes at that time.

However, the act of changing shoes also indicates a problem. The person who came here probably did not suddenly break into Wang Feng's home and take him away directly. The person should know Wang Feng.

After all, I never heard anyone say that a certain criminal suspect even changed his slippers during the execution.

Since they didn't break in suddenly and take Wang Feng away directly, it can also be shown that Wang Feng is probably safe now.

Next, Lu Chuan began to exert force on the two pairs of slippers.
