traces of all things

In the end, the meal was still unfinished.

In a group of small cars, Wei Xiongfeng sat in the driver's cab, visibly sluggish.

"I'm so stupid, really. If I knew I was a crow's mouth, I shouldn't have set up a flag. If I hadn't set up a flag, I wouldn't have been notified that there was a case and I didn't have to work overtime. If I didn't have to work overtime, I might have already I'm having a date with the pretty sister from the finance department downstairs and drinking a little wine. If the atmosphere is better, maybe I can go to a movie. I was very excited when I watched her game in the afternoon. It must be because I liked my commentary... "

"You are so stupid, really." Geng Zhizhong suddenly turned his head in the passenger seat, and complained precisely: "You didn't even realize that the little girls were looking at Lu and Xiao Tang and screaming, and you thought they were looking at you. If it's not stupid, what else can it be?"

Wei Xiongfeng was hit by a hundred arrows in his knee and fell to the ground in an instant.

Sitting in the back seat, Lu Zheng watched Geng Zhizhong beat Nobita, and the depression of working overtime at night dissipated a little. He couldn't help but ask, "Boss, what kind of murder is this time?"

Geng Zhizhong shook his head: "It's not a murder case yet. The city bureau received a report of a missing woman a while ago, and they searched for it for several days, but they couldn't find it."

"The missing case?" Tang Shaoyuan was a little puzzled: "The general city bureau handles this kind of case by itself, right?"

"Indeed." Geng Zhizhong shook his head: "However, it seems that the Municipal Bureau has made some new discoveries today, and the technical team found something suspicious, but they couldn't convince each other. Xue Yiwei and Xiao Xue from their elite team sent a report to Captain Huang Ying requested—”

Speaking of this, Geng Zhizhong couldn't help laughing: "—According to what he said, please ask Team Leader Lu Zheng, who is 'clear enough', to help them take a look."

Lu Zheng: ...Suddenly I feel so ashamed.

Not to mention, he almost forgot Xue Yiwei, the king of rainbow farts.

Captain Huang Ying is the head of the Criminal Police Brigade of the Municipal Bureau. As a strong woman, she not only works very hard, but is also very good at using resources from all sides. When Xue Yiwei said that she wanted to ask Lu Zheng to help, she immediately made a decision—— Please invite one, please invite a bunch of people, just invite them all over here!There is great power in numbers!

So there was this night of overtime work that made Wei Xiongfeng resentful.

After hearing the whole story, Wei Xiongfeng couldn't help gnashing his teeth.

I feel like I hate Xue Yiwei even more today.

"The name of the missing person is Jiang Yixiang, female, 32 years old, unmarried, a math teacher and dean of a boarding school for migrant children in Wenyuan, the provincial capital." Xue Yiwei stood up straight, and put a piece of household registration information on the provincial hall. In front of him: "I disappeared three days ago, and I have no contact with my family. The caller was Jiang Yixiang's mother. She said that her daughter would call her every night, but there was no news three days ago. She was worried that her daughter was busy with work, so she called her." I waited for a day, but I still didn’t believe it, until the school called Jiang Yixiang’s home because Jiang Yixiang didn’t come to work, and then realized that her daughter was missing, and immediately called the police.”

The photo on the household registration information shows a woman with a serious face and thin cheeks. She looks a bit old-fashioned, but her eyes are firm and she has the taste of a strong woman.

"What happened next?" Lu Zheng asked.

"This evening, our investigators found Jiang Yixiang's bicycle on the side of a small road. It was unlocked and parked there. According to Jiang Yixiang's colleagues in the school, the last time she appeared in the eyes of everyone was at the school gate. I just rode a bike like this. I thought it was a bit strange, so I checked the bike after I got back and found a few suspicious things."

Xue Yiwei said, frowning, and pointed at the lady's bicycle in front of him with his gloved finger: "First of all, I didn't find any fingerprints on the handlebar of this bicycle, and it was carefully wiped clean."

Lu Zheng raised his eyebrows instantly.

This is suspicious. If Jiang Yixiang rode the bicycle to the side of the road, why did she wipe off the fingerprints on the handlebars of the bicycle?If it was not she who was riding the bicycle, but the bicycle was stolen, then the thieves would not have left the bicycle aside. Looking at it this way, there may be some mystery in this bicycle.

"There is also the second point, which is also what makes me feel the most suspicious." Xue Yiwei looked a little nervous, took out a piece of printing paper and handed it to Tang Shaoyuan, and guided Lu Zheng to look at the fender in front of the car : "Leader Lu, look here."

Lu Zheng squinted his eyes and noticed that there were scattered splash marks on the front fender of the bicycle.

"This is human blood."

Xue Yiwei said with a heavy tone.

"And it belongs to Jiang Yixiang." After glancing at the DNA comparison report, Tang Shaoyuan also said firmly.

Lu Zheng's heart sank, and he observed carefully again.

The blood spots are splatter-shaped, with rough edges and a star shape. Judging by the shape, this splattered blood should have been splashed at least two meters away.

Unless Jiang Yixiang had been hit or injured by a sharp object on the side of her bicycle, it was rare for an accidental small wound to cause such a far-splashing bloodstain.

Lu Zheng's heart grew colder and colder.

This stern-faced female dean is likely to be in danger.

**

The place where the bicycle was found was not very far away. Just to be on the safe side, Lu Zheng decided to take physical evidence like the bicycle to do a comparison to see if he could find some clues such as rut ​​marks.

The scene is located in the urban-rural fringe area on the outskirts of the provincial capital, which is different from the bustling provincial capital. Light bulbs, shouting and selling fruit department stores.

"This road is a relatively prosperous place in this urban-rural fringe area. Many cars pass by during the day, and some people set up stalls on the side of the road to do business for these car owners. The place where the bicycle was found is in a small fork on the side."

Lu Zheng took Wei Xiongfeng and Tang Shaoyuan, and followed Xue Yiwei's footsteps all the way to the place where the bicycle was found.

This place is quite remote. From the cement road under your feet, you can see that there are not many cars passing by, but this kind of rough cement road is not easy to collect marks. Lu Zheng studied for a long time before he was near a small puddle. A little shallow imprint was extracted on the wet silt.

"This imprint is relatively shallow, and the forward direction of the tire is forward. Judging from the depth of the side sag, the rider should be relatively thin and weigh no more than 130 catties."

"If it's not more than [-], what if the rider is a shorter woman? Isn't it possible that she is fatter?" Wei Xiongfeng focused on taking pictures with a single-lens reflex camera on the side, Xue Yiwei followed closely asked.

Lu Zheng was used to his studiousness and questioning, so he didn't feel offended, so he smiled at him with a good temper: "No, look."

As he spoke, he walked to the side of Jiang Yixiang's bicycle, stretched out his long legs for a gesture, and then called Wei Xiongfeng and asked him to stand beside the seat: "Did you see it?"

Xue Yiwei is very smart, and immediately got to the point: "—Long legs! By the way, if the rider is the same height as Wei Xiongfeng, then he can't even step on the pedals!"

A few black lines burst out from Wei Xiongfeng's forehead: ...what did I do wrong to be cueed like this!

After finishing speaking, Xue Yiwei looked at Lu Zheng with admiration, and stabbed Wei Xiongfeng again: "Team Leader Lu is really amazing, I really need to learn more from you. When I checked this car before, I guess it was because I was right. For myself, there is nothing wrong with the height of the seat, so I ignored this key clue."

Are you taller than you are amazing!

Wei Xiong grumbled and turned around and left, only thinking that he should be paid three times the wages for overtime work, it's so embarrassing!

What Lu Zheng said is indeed correct. The seat height of this bicycle has been adjusted. The missing Jiang Yixiang is petite, less than 1.6 meters. If it is at this height, there is no way to step on the pedals. A person's stature should be at least 1.7 meters five. If this height and weight are less than 130 catties, they are considered thin regardless of gender.

Of course, men are more likely.

It's just a pity that after Lu Zheng checked the buckle for adjusting the height of the seat, he found that although there were fingerprints on it, they were blurred and could not be recognized at all, and he didn't know whether it was intentional or unintentional.

With the footprint lights on on the small fork road, the track of the car can be barely recognized, but there is no trace at all on that cement road. Many vehicles coming and going in a few days have already wiped away the rut marks of the past. clean.

The investigation once again reached a dead end.

Lu Zheng touched his chin, frowned, pouted slightly, and stood on the side of the cement road thinking for a while.

Seeing his serious expression, none of them made a sound, quietly waiting for him to make a new step.

Not long after, Lu Zheng's eyes lit up, and he took out a mobile phone from his trouser pocket.

Just when Wei Xiongfeng thought that their team leader was going to do something cool, he saw Lu Zheng's slender fingers press a few times on the screen of the phone to open...

... A thousand-degree map.

puff.

"Team leader, don't you know the way back?" Wei Xiongfeng said kindly: "I'm driving, it's fine, I still remember."

Lu Zheng used two fingers to zoom in and out of the area, and finally raised his head from the phone. Hearing this, he couldn't help but stretch out his hand and rubbed his head amusedly: "What are you thinking, I just suddenly thought of a A new possibility—we might be able to find some clues about Jiang Yixiang in Xiaocang Mountain."

Ga?

Wei Xiongfeng looked puzzled, but he saw that Tang Shaoyuan and Xue Yiwei followed Lu Zheng and walked along, trotting all the way to follow and press the car door lock.

After getting in the car, Lu Zheng sorted out his thoughts, and told the boys in the car why he chose Xiaocang Mountain.

"Because the economy is backward, the terrain in this area is actually relatively simple, not as complicated as the city center." He said: "First of all, based on the rut marks in the small fork road, we can guess where the cyclist came from on the main road. Cycling from north to south, we can reach the elementary school where Jiang Yixiang works by going north on this road. This is also the place where her colleagues last saw her riding a bicycle."

"Assuming that Jiang Yixiang has suffered some kind of infringement, then from a criminological point of view, one possibility is that the murderer rides her bicycle away, stealing sheep or stealing money, and the other possibility is to avoid the bicycle from being found too large. , trying to hide the fact that he committed a crime.”

Speaking of this, Lu Zheng's expression became serious: "The car was abandoned not far from the elementary school, so the first possibility can basically be ruled out. According to the second possibility, criminals will tend to take the bicycle Abandoned in a place farther away from his crime scene, from this point of view, it is very likely that his crime scene is further north from Jiang Yixiang's elementary school."

The location of Wenyuan Primary School is very remote, and there is only one north-south road in front of the gate.

And continue to drive north along that road, and soon, a small hill in the night appeared in front of several people.

It is Xiaocang Mountain.
