traces of all things

Captain Tian moved quickly, and immediately went through the procedure to approve a search permit after Lu Zheng filed the application.

"This bloody glove mark is different from ordinary bloody glove marks." Lu Zheng seized the opportunity to help Tang Shaoyuan and Wei Xiongfeng popularize science during the time he was driving to Zhan Jiaxing's house: "The finger marks of this glove mark The knuckles, as well as the wefting part of the palm are somewhat blurred, and there are some twists in the shape of an 'S' if you look closely."

Tang Shaoyuan was sitting on the back seat of the car, holding the picture of the glove imprint taken at the scene in his hand, pushing his glasses with his right hand, looking a little confused: "Brother, to be honest, I really didn't see it."

"There is a specialization in art, if you can see it at a glance, how can I live on?" Lu Zheng approached with a smile, the car was a little bumpy, and he simply stuck his whole body next to Tang Shaoyuan, holding the photo in one hand and the other in the other. Going around his shoulders, he stretched out a slender finger and pointed at a point on the picture: "Here, here it is, take a closer look at this quadrilateral area, and compare it with the surrounding marks—see it? "

This is still... look at the wool.

Most of his body was sticking together, and it was so hot that Tang Shaoyuan's blood boiled a little, and he couldn't help but want to hide to the side, but he was a little bit reluctant, so he sat in his original position and dared not move.

"Oh, I'm sorry, it's hot." Lu Zheng suddenly seemed to notice his unnaturalness, and moved to the left simply to make an empty seat: "I'll move to the side. "

No!I could have made it even hotter!

Tang Shaoyuan didn't show it on the surface, but he raised Erkang's hand with tears streaming down his face.

Without the giant source of interference around him, Tang Shaoyuan observed carefully for a while in his heart, and finally saw some strange traces in the photo, and raised his eyebrows in surprise to look at Lu Zheng.

"Smart. Shao Yuan is really a good material for trace inspection." Lu Zheng is very satisfied with Tang Shaoyuan's understanding: "If you are not a forensic doctor, I will definitely chase you to be your master."

Just when the two of them looked at each other and laughed without saying a word, Wei Xiongfeng's distraught voice came from the driver's seat again: "Team leader! You're making a fuss and you don't take me with you!"

No matter how young the official is, Lu Zheng is also the leader, and Tang Shaoyuan has higher qualifications than him. Wei Xiongfeng, who is at the bottom of a group of food chains, was thrown into the cab without the love of his colleagues as soon as he went downstairs. At this moment, he was scratching his heart with curiosity. However, it is a tragedy. In order to drive safely, he can only hold the steering wheel honestly and look straight ahead.

"I'll show you when I get back." Lu Zheng smiled: "You happen to be driving now, imagine the movement of holding the steering wheel, and you will know why I said that Zhan Jiaxing is suspected of committing a major crime."

Tang Shaoyuan raised his hand to imitate the action of turning the steering wheel: "So the twist marks on the weft in front of the palm are caused by the murderer often wearing gloves to operate the steering wheel!"

Wei Xiongfeng also rubbed his hands on the steering wheel in the front row, and finally realized: "Zhan Jiaxing mentioned when he was interviewed last time that he is a taxi driver who works the night shift—"

"Yes. From the very beginning of this case, we ruled out the possibility of seeking money. The murderer did not take away the jewelry on the old lady's bedside table, and the murderer made very good preparations and entered the scene peacefully. ——In addition to hiring a murderer to kill, it is only possible to say that the murderer is an acquaintance of this family, and there is an emotional entanglement or hatred relationship between them." Lu Zheng added: "Working gloves are also often used by taxi drivers, large truck drivers, etc. The gloves are cheap and have great friction, among the acquaintances of Zhan Jia and his family, apart from Zhan Jiaxing, there is no one else who has been in contact with the steering wheel for a long time because of work needs."

**

Together with the investigators, several people turned upside down at Zhan Jiaxing's house.Because of the too much stimulation from the previous two days, Wen Jiao, who was pregnant, stood aside, her face was pale, and she looked like she was about to faint at any time.For this reason, Lu Zheng specially hired a female investigator to do ideological work for her.

The most direct evidence is undoubtedly the pair of blood-stained labor insurance gloves. Unfortunately, in Zhan Jiaxing's car, Lu Zheng only found a pair of new gloves that had just been taken apart.The size 39 Jiefang shoes also disappeared.

Unlike the wealthy Zhan Jiahe's family, Zhan Jiaxing's living environment is relatively tight at first glance. It is the type of old family building with a small courtyard. It is estimated that it will be demolished in a few years to match the city's construction.Lu Zheng walked around the house, found nothing, and stood at the door to scan around again.

Suddenly, near the door, a small coal-burning stove caught his attention.

"Is this stove yours?" Lu Zheng found Wen Jiao and asked. At this time, she seemed to have stabilized a lot, but she was still a little uneasy.

"Yes." She bit her lip: "This stove is actually used by Jiaxing and I for cooking. Our house is too old and there is no natural gas."

Lu Zheng still looked kindly: "Then why is this stove placed in the yard?"

"...I don't know, maybe Jiaxing took it out. I haven't been in good health for the past two days, and I haven't cooked any food." Wen Jiao said hesitantly.

Lu Zheng had an idea in his mind, put on his gloves and dug in the hearth for a while, and took out a lot of flakes of ashes. In the ashes, he also found a few small pieces that hadn't been burnt clean, which seemed to be Some burlap texture fabrics have been smoked to a bit black.

He collected the fabrics carefully, and as soon as Lu Zheng looked up, he saw Tang Shaoyuan coming out from the back of the house, wearing gloves, frowning, and holding a dirty kitchen knife in disgust.

"I found this from the garbage room behind the house." Seeing Lu Zheng's curious face, Tang Shaoyuan explained: "We were lucky, this kitchen knife just fell out of the garbage can, and the garbage collectors are more I was careless, so I didn’t take it away. I compared the gap on it, and it is very likely that this is the murder weapon.”

The garbage room in this community is still in the style of the 90s. It is made of cement and tiled, making it look like a real small house. There are two square "windows" on the front, and there are two garbage cans under the windows in the house. The door is usually locked. When the garbage collectors come over, they just open the door and drag the trash can out to empty it.Such a garbage room looks good from a distance, but when there is a lot of garbage, it will fall out of the bucket and fall into the garbage room. It is relatively hidden and not easy to clean, which is just cheaper for Lu Zheng and the others.

It is natural to be happy to find the key evidence, but the garbage room is really smelly, and there is a lot of yellowish brown sewage at the door. This time I went out in a hurry, and Tang Shaoyuan didn't even have time to wear a mask. I really don't know. How did he, a meticulous person who loves cleanliness, endure it.

"Thank you, Shao Yuan." Lu Zheng looked at him with satisfaction: "When the case is over, brother will treat you to seafood."

Tang Shaoyuan held his breath, put the dirty kitchen knife into the evidence bag, and returned a somewhat pale smile to Lu Zheng.

**

As Lu Zheng expected, the DNA of Zhan Jiaxing and his wife was detected on the kitchen knife found in the garbage room near Zhan Jiaxing's home, and the piece of cloth left in the stove was also confirmed to be part of the labor protection gloves. The above inspection found bloodstains of Gong Ziqiang and Chen Afen's old couple.

Zhan Jiaxing was quickly taken back to the Municipal Public Security Bureau.

After hearing that Zhan Jiaxing had been brought to justice, Zhan Shengnan's last line of psychological defense was also broken. She who had been cold and unwilling to admit it before finally lowered her head and showed a relaxed expression.

"why?"

The question Geng Zhizhong asked may be a common question in the minds of everyone in the interrogation room.

Zhan Shengnan used to have a happy family. Although Zhan Jiashou and his wife were not very rich and powerful, they did not have to worry about eating and drinking. Zhan Shengnan is a little girl. After the great changes in her family, she can't spend much by herself, and there is not much financial pressure. .There should be no conflict of interest between her and Zhan Jiahe and his wife.Moreover, according to Zhan Jiahe's mother, after the death of Zhan Jiashou and his wife, Zhan Jiahe and his wife originally took Zhan Shengnan into their home to take care of them. Later, Zhan Shengnan refused to give up, but Zhan Shengnan occasionally went to his house for dinner a few times. Not great, but no hate either.

Facing her own cousin, cousin, two children who only went to elementary school and junior high school, how did she do it?

Zhan Shengnan himself seemed to be in a trance.

"I also think this is very strange." When the little girl said this, her face was cold and a little puzzled, as if she wasn't the one who did such a cruel thing: "I haven't figured it out until now. The whole thing was incredible."

"You're unbelievable ass..." Wei Xiongfeng's endurance was relatively low, and he was so angry that he opened his mouth to curse, but Geng Zhizhong blocked it with a wave of his hand, and received a cold stare from the leader. Wei Xiongfeng immediately bowed his head and admitted his mistake, and then walked out of the interrogation angrily room.

Zhan Shengnan glanced at his back coldly, tilted his head and continued to say with an indifferent expression: "The reason is very simple. Both my third uncle and I dislike this family. My third uncle told me that I Grandma has a bad heart. She was diagnosed with lung cancer a while ago, and she won't live long. We deal with the second uncle's family, and his family's inheritance will be inherited by my grandma, and it will be divided between me and third uncle in a short time On top of that, he will give me an extra 50 at that time."

Lu Zheng noticed sensitively that Zhan Shengnan used the word "handling" when referring to her second uncle's family, as if he was talking about a few courier packages instead of six real lives.

Her indifference made everyone present feel a chill in their hearts.

"It just so happens that I'm short of money recently."

Zhan Shengnan summed it up in one sentence, then leaned back on the chair, and the shackles on the chair made a rattling sound.

There was silence in the interrogation room.

After a few seconds, Geng Zhizhong let out a long breath, raised his head again, his eyes were firm and serious:

"Tell the story of your crime from beginning to end, in chronological order, and don't miss the details."

The author has something to say:

Dangdangdangdang, the two murderers were finally brought to justice!

Why is Zhan Shengnan short of money, why Zhan Jiaxing killed his relatives, and if you want to know what happened next, let’s listen to the next chapter to break it down~

And is the copy of Ning Hai finished?Let the author squeeze his fists to tell you that of course he hasn't, please continue to look forward to it

All the friends in the ps comment area have big brains!It's still very interesting, I really want to pass the pen to the big guys, hehehehehe

----

Typical occupations such as car drivers, porters, fitters, masons, etc., who often need to wear gloves for labor, have different characteristics in the wear and tear of the knitting and weft lines of their gloves, which have specific characteristics in the branch of textile traces of trace inspection. The research and summarization are very powerful.

Let's keep calling for science!
