traces of all things

Kong Guoan's statement caused several people in the inquiry room to secretly exchange glances.

"How is the relationship between Han Lei and Jiang Yixiang? What about Jiang Yixiang's relationship with colleagues? Can you tell me about it?" Huang Ying asked, tapping the pen in her hand.

"Jiang Yixiang, she's not very popular. Except for Han Lei, no one seems to be close to her." Kong Guoan bit the butt of his cigarette, which seemed to be a little bit unfinished: "Jiang Yixiang is a bit of a woman, and she is very serious. Forget it, and let people be with her, it's annoying, she doesn't look good, I don't like to talk to her. I don't know why Han Lei and her are so tired, I want to hold hands in the bathroom-but usually Jiang Yixiang looks like Han Lei's old mother, Han Lei is not in good health, Jiang Yixiang cooks for her and buys medicine and fruits for her all day long, maybe because of this."

Kong Guoan shrugged his shoulders while talking: "It's not fair, if Jiang Yixiang didn't guard Han Lei like a door god every day, I could also buy her food and fruit."

For a long time, this is the natural hostility of suitors to girlfriends.

Lu Zheng nodded slightly, but did not continue to ask.

In the next few hours, Lu Zheng and the others worked together to inquire all the teachers in Wenyuan Primary School, from the principal to the teachers of each subject, and the conclusions they came to were basically the same: very dedicated, not many friends, serious , no boyfriend, no ambiguous object.

"If it's not an acquainted man, could it be... an indiscriminate crime by a stranger?" Xue Yiwei rubbed his chin and muttered.

At this time, they had already contacted Jiang Yixiang's university senior who had had many contacts with him. This person was married at the beginning of this year, and his work location was also transferred to Ninghai City. He hadn't been to the provincial capital for a long time.

"It's possible." Xian Hongru, deputy head of the brigade, flipped through his work notes: "But when we visited nearby villages, no villagers or residents said that they had encountered suspicious people with exhibitionism or other related criminal records. "

"I haven't heard of anyone suffering from impotence." Wei Xiongfeng immediately added: "However, if you have this problem, you won't use a loudspeaker to talk about it every day. It's not strange that people don't know about it."

"Continue to investigate." After thinking for a while, Huang Ying said, "Let's go to Jiang Yixiang's school in the afternoon to see if we can find any new clues. Now we will trace the clue of sexual dysfunction and investigate the surrounding clinics and hospitals. .”

Everyone nodded, and left the inquiry room with their belongings.

Soon there were only Tang Shaoyuan who was studying the autopsy results, and Lu Zheng who was sorting out the traces and evidence at the scene.

Lu Zheng has already done half of the things at hand, and now he is naturally sorting them out quickly, and he finished them all in a short time. After registering all the traces and evidence, he straightened up and stretched his legs vigorously. arm.

There was a dangerous clicking sound from the shoulders and neck.

"hiss……"

The sudden pain made Lu Zheng frown uncontrollably.

Tang Shaoyuan sat looking at the autopsy photos, his two long eyebrows were twisted into a knot, he was very confused when he saw it, his ears moved when he heard the sound, he put down the photo in his hand, got up and walked over.

"Hmm...~"

The back of Lu Zheng's neck enjoyed a professional-level massage again, and he squinted his eyes so comfortably that he let out a long sigh.

Hearing this voice, Tang Shaoyuan's fingers subtly stopped.

"Eh?"

Lu Zheng, who was immersed in the massage and couldn't extricate himself, opened his eyes, raised his head with a smile, looked at Tang Shaoyuan from bottom to top and said, "Good Shaoyuan, can you give me another press?"

Tang Shaoyuan looked at Lu Zheng's face close at hand, and felt that this angle of death made him look good. As if he was bewitched by something, he stretched out his hand to hold Lu Zheng's face and slowly lowered his head. It stopped ten centimeters away.

Looking at Tang Shaoyuan's focused eyes and long eyelashes, Lu Zheng's heart skipped a beat for an instant.

At that moment, Tang Shaoyuan seemed to wake up suddenly, his face was flushed, and he jumped a meter away in an instant as if springs were installed under his feet.

There was an awkward silence in the room.

Lu Zheng didn't know why, but he also felt a little blushing, and quietly pressed his hands on his chest.

Boom, boom, boom, the sound is like beating a drum.

"Cough, Shao Yuan, you..."

"Brother..."

In the silence, the two spoke at the same time in a tacit understanding.

"You speak first."

"What do you want to say, brother?"

Another sentence in unison.

"puff……"

This time it was Lu Zheng who smiled, his eyes were crooked, and his face was still a little flushed. Seeing this, Tang Shaoyuan also smiled with the corners of his mouth in a daze.

The awkward and tense atmosphere in the room immediately dissipated with laughter.

"Okay, it's confirmed this time. Tell me first, what's the matter?" Lu Zheng still didn't forget the conversation just now after laughing.

"It's nothing." Tang Shaoyuan opened his mouth, but turned a corner when he spoke, and fiddled with the photo in his hand with his head down: "Brother, you should pay more attention to the combination of work and rest in the future. If you have a bad posture when writing and reading, your neck will be very tight." It hurts easily——what did senior brother want to say just now?"

"I'm fine." Seeing him embarrassed, Lu Zheng was also a little embarrassed to continue the topic just now, and asked about work: "Just now you looked at the autopsy photos and seemed distressed. Do you have any new ideas?"

The topic came back to work again, Tang Shaoyuan felt relieved again, and felt a little pity, shook his head and put aside all the miscellaneous thoughts: "I don't have any new ideas for now, but I still can't figure out how the murderer made me Teacher Jiang died of suffocation."

"Just now I asked the city bureau's forensic doctor to help with the diatom test. Mr. Jiang didn't drown because of choking, and there were no pressure marks on his mouth and nose."

This is indeed the biggest problem that bothers him. If the method of death cannot be confirmed, there is no way to write an autopsy report.

Lu Zheng stretched out his hand and asked him for a photo: "There are so many people, so I will come and help you think about it."

The photos were taken at the scene of the crime. Wei Xiongfeng's hands were very steady, and the photos were taken clearly even in poor light.What Lu Zheng is holding in his hand is a close-up of the frontal face of Jiang Yixiang's corpse. This face is black with mud, and some facial features can only be discerned barely.

Lu Zheng narrowed his eyes, took out a magnifying glass and carefully studied the edges of the corpse's cheeks.

When the magnifying glass moved close to the left jawbone of the corpse, his hand suddenly stopped.

No, if the murderer soiled Mr. Jiang's face in order to humiliate women, then the dirt on Mr. Jiang's face should be a thin layer underneath and loosely piled up in the middle...

…After all, no matter whether you grab a handful of dirt and smear it on, or press your face into the dirt, since the human face is not flat, there will definitely be a small part of it covered with a relatively small amount of dirt.

And now, the soil on Teacher Jiang's face is distributed too evenly, right?

Thinking of this, Lu Zheng's hairs instantly stood up, and he grabbed the magnifying glass to observe Jiang Yixiang's face more carefully.

That's right...it's so even, it's almost like applying a mask.

What was even more suspicious was that near Jiang Yixiang's forehead, some of the soil had fallen off, and the edges were extremely clear, as if a clay mask had been broken from the middle, revealing a clear edge.

"He's so ruthless, how can he do it..." Suddenly, I recalled the forensic doctor's comment after Yu Haiyan committed suicide in the Yuanbao City Detention Center last time: "...wet the toilet paper with water and wipe my mouth Cover your nose and suffocate..."

Lu Zheng's hand suddenly grabbed Tang Shaoyuan's wrist.

"Oh my God, Shao Yuan."

he murmured.

"I think I guessed how the murderer suffocated Teacher Jiang."

**

Provincial Urban Bureau Criminal Investigation Technology Laboratory.

Wei Xiongfeng and the others moved a small bench and sat on the edge of the laboratory table to watch Lu Zheng, wearing gloves, paste mud on a machine.

"Brother, the result is out." Tang Shaoyuan pinched a stopwatch on the side to check the time, and kept his eyes on the computer screen: "After this kind of soil sample is mixed with water, the air barrier property is not inferior to that of ordinary thick fabrics. .”

"In other words, it is entirely possible for Jiang Yixiang to suffocate to death because her face was covered with water-added mud."

Wei Xiongfeng sat on the side, biting his fist with his teeth, his eyes widened.

"So, the process of the murderer's crime is like this." Lu Zheng took off his dirty gloves and said thoughtfully: "First, he hit Jiang Yixiang's head with a stone to make her lose her resistance, and then put She dragged her into the grass behind the stone wall for molestation, and then mixed water and mud on Jiang Yixiang's head and face, causing her to suffocate to death."

"Why did he do this?" After Lu Zheng finished speaking, he also felt a little unbelievable: "There are so many ways to kill directly, if he wants to kill someone, he can definitely use methods such as strangulation? Is it really just to humiliate the victim?"

"I wonder if he saw the news of Yu Haiyan's suicide in the detention center, so he adopted this rather curious method?" Wei Xiongfeng offered an idea.

"It's not impossible..." Lu Zheng nodded thoughtfully.

When the group was puzzled, the door of the laboratory was pushed open.

"Lu, Daxiong, Xiao Tang." The person who came in was the dusty Boss Geng: "Have you finished the experiment? If it's all right, we're going to Wenyuan Boarding School now, and you all should come together."

**

The name of Wenyuan Boarding School is nice, but the school building is very dilapidated, the walls around the school are covered with grass, and there is no one guarding the gate, only an old man who looks dizzy, wearing a security uniform, sitting Dozed off in the reception room.

"Is this school really a decent school?" Wei Xiongfeng glanced around with incredulous eyes: "I think this teaching building looks like a dilapidated building at first glance."

Not only the teaching building, but the student dormitory at the back also looks shocking. It stands alone behind the school building, with fields behind it, without even a railing, and sheets and mops are casually hung on the balcony. It seems that the conditions are so poor People are sad.

"Several police officers come here." The person who spoke was a thin old man with a bunch of keys on his body, wearing a frayed jacket. It was not at all obvious that he was the principal of an elementary school: "This Next to it is the dormitory of Xiao Jiang and Xiao Han. Xiao Han has been hit too hard recently, and she is not in good health, so she went to the clinic this afternoon for an injection and left me the key."

The teacher's dormitory looks as dilapidated as the student dormitory, but the student dormitory is a two-story building, and the teacher's dormitory looks like a row of small bungalows, located in a corner of the school.

Accompanied by the principal's introduction, a wooden door "creaked—" was pushed open.

Lu Zheng put on his shoe covers and gloves and pushed the door open.

This small room is only about ten square meters. There is no bathroom in the room. A few hemp ropes are pulled at one end near the window. Some clothes are dried on it, and two washbasins are used to catch water underneath.The furniture in the room was only two single beds and two sets of tables and chairs. Although they were very old, they were wiped clean and the beds were tidy.

Lu Zheng first walked to the space on the left. It can be seen that this space is used by Jiang Yixiang. There are two photos on the small table, one is a photo of her and her mother, and the other looks older. Some seem to be group photos of college classmates. In the photos, both men and women are young and lively. Jiang Yixiang is holding scissors together in the crowd, with a smile on his face, looking in a good mood.

I looked at Jiang Yixiang's bookshelf with a flashlight for a while. This dormitory has a limited area. Jiang Yixiang put a small simple bookshelf on her desk. The books on it were neatly stacked, but a little loose.

Lu Zheng stretched out his hand to shake it, and found that the loose gap was just big enough to hold a book.

"Mr. Jiang was not called out temporarily when he went out this time." Lu Zheng said firmly after looking around for a week.

Wei Xiongfeng was still taking pictures of the bookshelves according to his instructions, and asked curiously, "Why?"

"She sorted out her lesson plans, notebooks, and collected student homework after class, put them in a locker and locked them before leaving the dormitory. If she was in a hurry to be called away, she might There won't be enough time to do it slowly."

Jiang Yixiang is not a literary young woman. Lu Zheng didn't find anything like a diary in her dormitory. He couldn't help but feel a little regretful. After checking around, they didn't find much, so they decided to go to Jiang Yixiang's office Look again.

However, an accident happened just as he was about to leave.

The room was very small, with a lot of things, and it seemed a bit crowded and there was no place to set foot. Wei Xiongfeng accidentally tripped while leaving, and almost dropped the camera in his hand.

"Oops—it hurts so much!"

With a sound of "bang", Wei Xiongfeng, who was in a hurry to rescue the DSLR, caught the camera a second before the camera fell to the ground, but he himself slammed into the single bed in front of him, and his facial features were instantly distorted in pain.

With a "click", something slipped from under the pillow on the single bed and fell to the ground.

The bed over there belonged to Han Lei, and Lu Zheng was afraid of getting his things dirty, so he hurried forward to pick up the thing that looked like a notebook.

The little book was thrown open, revealing its contents—it turned out to be a small photo album.

Lu Zheng was about to close the cover of the album, but suddenly his attention was attracted by the content inside.

"what--?"
