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

The traces of existing footprints covered at the site are not such large flat coverings, but pure footprints.

Lu Chuan lay on the ground and continued to observe. Could it be that the other party really floated in?

impossible.

The suspect had tampered with the house like this, so there was no way he had left no trace at all.

From the living room to the bedroom, Lu Chuan paid close attention to every detail, carefully observing every small difference on the ground.

"Brother Hui, I have a variable frequency laser spectrum analyzer in my car. Please help me get it."

Lu Chuan seemed to have made some discoveries, but he was a little unsure. Many details were not very clear under natural light.

"Okay, wait for me for a while."

Ten minutes later, Lu Chuan got the spectrum analyzer and closed the curtains in the room. The light suddenly dimmed.

After turning on the spectrum analyzer, Lu Chuan adjusted the laser frequency and irradiated it onto the ground, and densely packed footprints suddenly appeared vaguely.

Yuan Shaokang, who was watching on the sidelines, was stunned for a while. Is the current criminal investigation technology so advanced now?

But after a while, Lu Chuan turned off the light source.

"Captain Yuan, we can't do it now. The light is still a bit strong after the curtains are drawn. Let's come over at night. I've found something that needs to be confirmed."

"No problem, but...Lu Chuan will have to trouble you to work overtime."

"What's the point of working overtime? In our line of work, what days don't we work overtime?"

"Don't move at the scene yet. If you can confirm my idea tonight, I think we can almost solve the case."

Lu Chuan didn't go into too much detail because what he just saw was unreal and there was no conclusive evidence.

On the way back to the detachment car, Zhang Hui couldn't help but be curious: "Brother, what did you just discover?"

"Nothing, just the footprints at the scene, the footprints left by the owner's family. After looking at them, they were all made by wearing slippers."

"There are three pairs of slippers in total. They are all placed in the wardrobe at the door. I took a look and saw that the shoes are relatively new and the marks are very clear."

"But there are some marks on some of the footprints. They are very slight. I don't know how they were formed. I can see them more clearly if I use a laser to illuminate them at night."

Zhang Hui was lonely after hearing this and really didn’t understand.

If it were fingerprints, he could still add a few words, but footprints...

Lu Chuan sent Shen Yan home first when he got off work. It was still dark when he got off work, so there was no use going there now.

Then I went home and had a meal, and the sky turned completely dark.

Without going back to the detachment to ask for a car, Lu Chuan drove his own car directly to the High-tech Zone.

It happens to be a little closer.

When Lu Chuan arrived, Zhang Hui and Yuan Shaokang were chatting.

"I suggest we still focus on investigating the residents in the building."

"Since the suspect did not enter or leave through the door of the unit, it must have been someone in the unit who did it."

According to normal thinking and logic, this is indeed the case.

There is one exit on the top of the entire building and one on the bottom. There are always people living on the roof. It is impossible for the suspect to leave through the roof without alerting the residents on the roof.

The high-tech zone criminal police brigade has already conducted an investigation on the monitoring of the unit door.

During the time when the crime occurred, the only people who came in and out of the unit were the owners and the delivery people. Then there were two relatives of the owners who came in and out. No other strangers came in or out.

Leaving aside the owner, the few people delivering the food took less than 3 minutes to enter and exit. It is impossible to complete the theft in such a short period of time.

Therefore, the theft suspect most likely lives in the unit and goes home directly after completing the theft. "The truth is this, but it is impossible for us to search all the residents in the unit building, and the owner's lost cash does not have a special mark. Anyone can have 1 yuan, and there is no way to lock the other party."

"Those gold jewelry may be locked by then, but how can we search for such small items?"

Not to mention that a theft case is a murder case. Without clear evidence, the police cannot randomly issue a search warrant and enter someone else's house to search.

"makes sense……"

"Hey, Lu Chuan is here."

Zhang Hui waved, and the spectrum analyzer was placed in the room that morning, so there was no need to move it back and forth.

Now that the sky was completely dark, and the curtains were closed, the lights of other residents had no effect. Lu Chuan turned on the spectrum analyzer and shined it on the ground.

The imaging was much clearer than during the day. The dense footprints seemed to be sprinkled with fluorescent powder. Under the laser light of a specific frequency, they stood clearly in front of the three people.

"here!"

Lu Chuan's conjecture has been further confirmed.

There are dot-like marks on some of the footprints, like a bald spot on the oasis, very obvious.

"what is this?"

"The suspect's tracks."

Ok?
Lu Chuan squatted next to a bald spot, took out a camera and started taking pictures, as well as some cotton swabs for collecting trace evidence.

While operating, he explained: "The suspect is very smart. It's not that he didn't leave any footprints at the scene, but his footprints are different from the general footprints."

"He must have tied something like stilts to his feet, so he left these dot-like marks on the ground."

Walking on stilts?
When Lu Chuan said this, Zhang Hui and Yuan Shaokang understood.

"And the high-strength gel found on the door lock this morning is generally used by magicians."

"Captain Yuan, are there anyone in this unit or community who are engaged in this industry?"

"As for this, I haven't done any early investigation in this area, so I'm not sure."

After making the discovery, Lu Chuan quickly completed the collection of spot marks.

"Give me some time. The footprints left by these dotted marks can only roughly determine the weight of the other party. I will go back and do a trace evidence analysis to see what the thing tied to the other party's leg is. You can investigate here. Let’s look at similar practitioners and we’ll meet them when the time comes.”

"Okay, I'll arrange it now."

Walking on stilts is not something ordinary people can do and requires a lot of practice.

Being able to flip around indoors on stilts is not something that ordinary people can do, and beginners will most likely not be able to do it.

The hardest thing about walking on stilts is not standing up and walking, but bending down and doing some large movements.

The suspect's stilts indoors were certainly not particularly high, and were probably just to cover up his footprints, but even if they were not high, they were not his own feet after all.

Therefore, Lu Chuan suspected that the other party might be a professional.

Lu Chuan didn't waste time and returned directly to the criminal investigation detachment.

The stilts the other party stepped on were not made of metal, otherwise they would have left scratches on the marble floor. Judging from the size of the marks, they should have been made of some kind of wood.

Lu Chuan collected some trace substances to see if he could analyze the active ingredients.

All that remains is the analysis and identification of the stains.

Because the material of the stilts is not metal, when it touches the ground, the size of the marks formed will be slightly different due to changes in the direction of force and center of gravity.

Lu Chuan now needs to roughly analyze some basic information about the suspect through calculations. (End of chapter)
