I am a super cop

Chapter 18 Trace Reasoning
Gu Chen naturally didn't take Comrade Zhang Jingde's indifference to heart. After the police officer Xiao Li escorted Wang Xiaoliu into the police car, he got into it himself, and a group of people returned to the scene of the crime.

"Bring Wang Xiaoliu here, I want to compare the footprints." Zhang Jingde took out his cigarette, looked sideways at Gu Chen, and then said to Xiao Li.

Xiao Li is his apprentice, and it is also his fifth year at the Xingfu Community Police Station. Compared with ordinary trainee police officers, he is obviously more professional.

Zhang Jingde has also met many trainee police officers like Gu Chen who have just graduated. He naturally knows some of the character traits of trainee police officers, so he doesn't expect Gu Chen to help him, so he wants to take him with him and let him learn more. some experience.

"Tell me the characteristics of the footprints at the scene." Comrade Zhang Jingde took a breath and said to Xiao Li.

"A pair of size 43 shoe prints were found in the dirt on the site, and they were sneakers with wavy patterns..." Xiao Li replied quickly and professionally.

Only by the vague footprints in the mud, you can accurately determine the shoe size, shoe type, and main grain, all of which have been investigated in advance.

However, Zhang Jingde just wanted to tell Gu Chen what a profession is.

Comrade Lao Zhang looked at Gu Chen, and said to Xiao Li, "Take it over for comparison."

Wang Xiaoliu quickly followed Zhang Jingde's request, walked a few more steps around the original footprints, and then returned to Zhang Jingde's side.

"What else do you have to say?" Zhang Jingde said unhappily, pointing at Wang Xiaoliu with a cigarette pinch: "This is clearly your shoe."

Wang Xiaoliu went up to have a look, and said, "It does look a little like it, but how can you say it's me?"

"Because I investigated you kid." Zhang Jingde also said frankly: "You are sister Hu's distant cousin, and you often come and go to sister Hu's house."

Xiao Li also added: "You often help Aunt Hu buy fabrics, so you have been in and out of Aunt Hu's house more times, and you are most familiar with the golden Buddha of Hu Dama, because this golden Buddha is usually placed by Aunt Hu In the partition under the bed, only you kid will know."

"But...but I have proof of my alibi." Wang Xiaoliu put on his trump card and said with a distressed expression, "No matter what, I can't do it, right?"

In a word, Comrade Zhang has a headache again...

If it weren't for this alibi, Zhang Jingde would have closed the case long ago.

"Huh? Where did Gu Chen go?"

When Zhang Jingde and Xiao Li were being interrogated, Gu Chen had already slipped through the cordon and took pictures of the footprints twice with his mobile phone.

Then he found a small wooden stick and poked it in the middle of the shoe print.

Gu Chen thought, just based on the proof that Wang Xiaoliu was not at the scene, maybe he could be ruled out as the suspect.

But if you always focus on this clue, it may be easy to miss other clues.

But if it is known that the only outsider of the Golden Buddha is Wang Xiaoliu, then this footprint is a bit strange.

Recently, Gu Chen made use of his specialization-level memory to make up for "Traces".

Through quick memory, some professional knowledge that was difficult to master in the police academy before, used these days to cram into his head.

Now it seems that it can also come in handy. Gu Chen made a three-dimensional measurement of the two footprints using a simple wooden stick at the scene.

"It is indeed a size 43 sneaker, and it is the same pair of shoes on Wang Xiaoliu's feet." Gu Chen nodded, expressing his agreement with Comrade Zhang Jingde's investigation results just now.

Xiao Li, the policeman at the side, couldn't help snickering twice, thinking that this was all investigated. Do you still doubt that Lao Zhang's investigation level is not good enough?After all, it has been the police for so many years.

No matter how bad it is, it's enough to teach you a trainee policeman.

Zhang Jingde coughed twice, and said, "Okay, don't walk around here, be careful to damage the shoe prints."

Gu Chen turned around and smiled: "Let me do it."

He walked up to Wang Xiaoliu and began to ask Wang Xiaoliu further: "Since Aunt Hu is your distant relative, does she have any other acquaintances? Preferably a woman."

Holding his chin, Wang Xiaoliu paused and said, "There is a niece who has a pretty good relationship with me. No matter what you say, you are all distant relatives, so you will have some contact."

"That's right." Gu Chen nodded and continued: "I know that Aunt Hu has no children, her husband also divorced early, and there are not many relatives in Jiangnan City, so you are one of them. Of course, there is also that niece , what's her name?"

"Lulu." Wang Xiaoliu replied.

"How is her relationship with Aunt Hu?"

"Not good." Wang Xiaoliu shook his head and said, "My cousin is very kind to Lulu, but since my cousin and aunt divorced, my distant cousin went to other provinces to do business, and since then we haven't seen each other again. But my aunt is very unfriendly to Lulu, and they often quarrel when they meet."

Hearing this, Zhang Jingde and Xiao Li looked at each other in blank dismay,
As a policeman in the jurisdiction, he didn't know that Aunt Hu had such a social relationship, but how did Gu Chen think of it?
In fact, Gu Chen has been able to see the trickiness of shoe prints based on the traceology he has mastered by using his professional memory.

Now combined with master-level reasonable reasoning, you will soon be able to find some relevant clues.

In contrast, Zhang Jingde and his apprentice Xiao Li obviously had a fixed mindset. They always used footprints as the only criterion for judging, but ignored other derivative clues.

"Gu Chen, did you find something?" Zhang Jingde asked suddenly, his attitude was much more modest.

"It's still footprints." Gu Chen said: "The footprints at the crime scene are deep in the middle and shallow at the edges, and the footprints that Wang Xiaoliu stepped on are exactly the same as the crime scene, but there is no such strange phenomenon. Explain the problem."

"What's the problem?" Xiao Li on the side was also very curious, he had already forgotten about Gu Chen's behavior just now.

Gu Chen didn't hold back, and said directly: "According to "Traces", there is only one explanation for this situation, and that is, these shoes are seriously ill-fitting."

Zhang Jingde and Xiao Li turned into elementary school monks in seconds, and entered the class time again.

Neither of them had ever learned this kind of knowledge, but now that Gu Chen said it, they felt a little interesting.

"The specific research objects of criminal traces are generally fingerprints, footprints, tool traces, the relationship between bullet traces and other substances, trace medium, freshness, etc."

"The study of criminal traces can determine the suspect's height, age, walking posture, tools used, action habits, etc., and provide scientific basis for exposing and proving crimes..."

After listening to Gu Chen's brief explanation, Zhang Jingde suddenly realized that he seemed to understand a little bit.

"So, the footprints left at the scene should be of a woman, and she came here wearing Wang Xiaoliu's shoes to commit the crime?"

Although Zhang Jingde has never studied "Traces", he has rich experience and his learning ability is quite fast.

According to the clues provided by Gu Chen, he quickly deduced that the perpetrator might be a woman.

However, Wang Xiaoliu's words made him disheartened again, and the breakthrough he had finally found was shattered again.
