Chapter 498 Floor Mats and Slippers
Before entering the room, Lu Chuan put on a full set of field survey equipment.
Because Wang Feng didn’t 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 didn’t know he was missing. If Yang Lin hadn’t called If they were asked to report the crime, they might not know Wang Feng's current situation.
So 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 will 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 site survey.
"Yang Lin, you follow Lu Chuan here to do the spot survey, while I walk upstairs and downstairs."
Huijiayuan Community was built relatively early, and it is a unit welfare house. , most of the neighbors are colleagues from Wang Feng’s father’s workplace.
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 staircase, and there is a neighbor across the door.
Soon the door opened, revealing a middle-aged woman in her fifties.
"Are you?"
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 was not wearing a police uniform, but Yang Lin was, and with the ID in Zhang Hui's hand, the woman quickly opened the security door.
"Oh, hello, Officer Zhang, hello, please come in."
Zhang Hui nodded and thanked: "Can I change my shoes?"
"No, no, no, you 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 know something about the situation and will leave immediately."
After a while, the woman sat on the sofa: "What do you want to ask Xiao Wang across from me?"
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 50-year-old retirees in the Criminal Investigation Detachment. There are women, 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 for three days. No contact with my family.”
“Missing?”
The woman looked slightly startled, and 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 passed the college entrance examination to the Public Security University."
"But no Do you know why he seemed to be expelled? "
"In recent times, some unscrupulous people have been coming to his house, and we think this child is a bad student."
"Why are you missing?"
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 that? Is there any unusual sound or situation on the other side? "Three days ago? There didn't seem to be anything special..."
While Zhang Hui was visiting and investigating, Lu Chuan had made some progress in some existing surveys.
Wang Feng’s home is relatively neat, unlike other bachelors who have messy homes.
This house is about 100 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 an important area for Lu Chuan to check.
"Kuanzi, what's there to check on the floor mat?"
This is the first time Yang Lin has followed Lu Chuan to watch him do a live survey, and some things are not very clear to him.
According to the style of handling cases by the police at the police station, just open the door and go in. If there is something that can be found inside, it will be found. If there is not, then 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 may be another person in the house at that time."
Yang Lin nodded, this is He found it when he checked Wang Feng's call records.
“We assume that the people in Wang Feng’s house at that time were related to his disappearance, so where did the other party come from?”
“The first step for the other party to enter Wang Feng’s home was to get on the floor mat. Leave traces. I will collect some soil and dust here to see if I can go back and do some trace evidence analysis. If the other party is really related to Wang Feng's matter, 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, somewhat suddenly 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 I 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 edge of the floor mat. Two pairs of slippers that are not very tidy.
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 their slippers and left."
Under normal circumstances, normal people rarely look back when they change their slippers. Take off your shoes and rearrange them so that your toes point toward the room.
What Lu Chuan just observed was whether the other party might wear his own shoes and leave marks on the floor tiles.
Compared with 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.
Unfortunately, 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 haven’t heard anyone say which criminal suspect even changed his slippers during the execution.
Since it was not a sudden intrusion and taking Wang Feng away directly, it can also be seen from the side that Wang Feng is probably safe now.
Next, Lu Chuan began to exert force on the two pairs of slippers.
