"Click!"

A sound of opening the door with a key came from outside the door, and Gu Chen, who was just about to leave, regained his footsteps and stopped at the door.

The door was pushed open, and a middle-aged woman wearing glasses and a slightly out of shape walked in weakly: "Husband, have you cooked dinner......?"

When the woman saw Gu Chen, she couldn't help blinking, and then when she saw Lu Weiwei and Officer Wang coming over, she suddenly chuckled in her heart, and looked ahead for some reason.

The first impression is: Did I go to the wrong room?

Think about it.

If it's someone else's house, then why can you open the key to your own house? Can all the doors of the house be opened by the key?

It has also happened before that a resident who goes to the wrong door opens another door with a key, and suddenly a key can open all the doors.

This kind of turmoil was caused for a while, and then it subsided after the lock was changed.

But it's not wrong to look at the furnishings at home.

"Wife. Just when the middle-aged woman hesitated, Lu Benxiong walked to the gate and quickly explained to the middle-aged woman: "Home...... There are guests in the house. ”

"Oooh. The middle-aged woman looked at Gu Chen, Lu Weiwei and Officer Wang, and seemed to be able to feel an invisible pressure from the eyes of the three of them.

But what the pressure is, the middle-aged woman can't say at all.

"Hello, I am Gu Chen, a police officer from the Criminal Investigation Team of the Furong Branch, and these two are my partners. ”

"My name is Lu Weiwei, and his name is Lao Wang. Lu Weiwei directly helped Officer Wang report to his home.

"Oooh. "It was also the first time for the woman to meet the police at home, and she was a little uncomfortable for a while.

"Huan...... Welcome to the house, do you have anything to do with my husband?"

"Actually...... I'm also here for you. Lu Weiwei said.

"Looking for me?" The middle-aged woman was stunned for a moment, looked at a few people with dodgy eyes, and said, "What are you looking for me? I don't seem to have done anything wrong, right?"

"We want to know more about Zhao Xiaomin from your company. Officer Wang also said directly: "Zhao Xiaomin has disappeared recently, I don't know if you know?"

"Ah, Zhao Xiaomin is missing?" The middle-aged woman put on a surprised face and blinked, "She...... How did she disappear? Didn't she resign?"

Lu Benxiong sighed and said, "Ah Ping, don't stand at the door, come in and talk." ”

"Oh, good. The middle-aged woman nodded, then put the bag on the shoe cabinet, then took off her high heels, changed into slippers and walked into the living room.

After everyone sat down again, Officer Wang and Lu Weiwei instinctively looked at Gu Chen.

But at this time, Gu Chen was half a beat slower than everyone, and he rubbed at the door for a long time before coming over.

"To start?" Lu Weiwei asked as she looked at Gu Chen.

Gu Chen nodded, turned on the law enforcement recorder again, and held the transcript in his hand.

"Hello, please give me your name, age and ID number. Gu Chen said.

"I ...... My name is Ding Ping, I am 36 years old, and my ID number is ......"

After Ding Ping finished speaking, he asked again: "Do you want to investigate me?"

"There's no investigation. Gu Chen glanced up at Ding Ping and asked, "Have you been anywhere after work?"

"I ...... I'm not going, hehe, where can I go?" Ding Ping seemed nervous.

Gu Chen nodded, and asked again: "In other words, after you get off work, you go home directly?"

"Yes. Ding Ping said.

"Then what is your means of transportation home?" Gu Chen asked again.

"Yes...... It's an imported car, and I usually drive home. ”

"That is, after getting off work, I haven't been anywhere outside the city, right?" Gu Chen's eyes were extremely sharp, and Ding Ping was at a loss.

"I didn't ...... That's right, I drove home after work and didn't go anywhere. ”

"But why is there dirt on your shoes?" Gu Chen didn't like to beat around the bush with her, and directly said his suspicions.

Ding Ping was stunned for a moment, and it took a long time to react: "Oh, you mean that the mud is written? That's ...... It was on the way home, and instead of going straight to the garage to pick up the car, I walked across a lawn and dirt slope to go shopping, and the mud on my shoes, probably from that time, I swear, I really didn't go anywhere. ”

"Got it. Gu Chen wrote it in its original form.

Lu Weiwei said: "Then can you tell us about Zhao Xiaomin's situation, including her character." ”

"Zhao Xiaomin? What does she have to say? She is beautiful and willful, and her work is okay, but she doesn't like to work overtime and is not very disciplined. ”

"Then Zhao Xiaomin is your husband's ex-girlfriend, do you know?" Gu Chen also asked directly.

Lu Benxiong, who was on the side, quickly coughed twice, turned his head to other places, and pretended not to hear.

Ding Ping glanced at Lu Benxiong, and his face suddenly changed: "I only learned about it recently, and my husband has never mentioned it to me." ”

"Then what is your attitude?Does Zhao Xiaomin's loss of contact this time have anything to do with you?" Gu Chen asked again.

I didn't say anything, Zhao Xiaomin resigned by himself, probably because he was embarrassed to see me at work in the company, so he left. ”

No matter how Gu Chen, Lu Weiwei and Officer Wang asked, Ding Ping seemed to be leaky and firmly occupied the moral high ground.

Just because he knew that Zhao Xiaomin and Lu Benxiong were ex-boyfriend and girlfriend, Ding Ping explained himself as a victim.

In her feeling, even her husband deceived herself, and even her direct female subordinates also hid herself, feeling that she was a fool.

So when the police questioned Ding Ping, Lu Benxiong on the side didn't say a word, and simply sat there.

"Comrade policeman, I'm a housewife. Ding Ping still answered positively, but did not help the clues of the case.

"Thank you for your cooperation. Gu Chen closed the notebook and looked at Officer Wang and Lu Weiwei.

Lu Weiwei understood in seconds, and said busily: "It's not too early, we should also leave." ”

"Why don't you stay and eat? I'll let Motoo cook a few good dishes. Ding Ping saw that the three of them intended to leave, and began to become polite.

"No, I'm bothering you two. Officer Wang also waved his hand and refused.

After the three left, they went straight back to the parking lot.

At this moment, Bai Xiaolan, who had been waiting in the car for a long time, immediately ran forward to greet her:

"How's it going? Did you find any clues?"

"Not for the time being, judging from the oral accounts of Lu Benxiong and his wife, there seems to be no so-called suspicion. Officer Wang paused and said, "But we are not completely clueless, Gu Chen seems to have made some discoveries." ”

"Gu ...... Gu Chen, I know that your observation skills are good, so have you found anything suspicious?Can you find my cousin?" When Bai Xiaolan spoke to Gu Chen one-on-one, her voice was obviously a lot more polite.

Gu Chen raised his eyebrows and frowned, did not say anything, but took out a packet of pollen packed in a transparent forensic bag with some earth.

"This ...... What is this?" Bai Xiaolan was stunned for a moment, and after getting closer, she observed for a long time, but she still didn't know what Gu Chen wanted to express.

"This is some of the dirt I scraped from the soles of Ding Ping's wife, Lu Benxiong's wife, and the pollen is hidden in the soil. Gu Chen took back the evidence bag in his hand.

"Could it be...... This is also called a clue?" Bai Xiaolan was skeptical.

It feels like some pollen, and if it's called a clue like this, then to find this pollen, isn't it looking for a needle in a haystack?

Lu Weiwei didn't think so, and said, "Since Senior Brother Gu can collect these pollen, it means that the place with this pollen is likely to be the location of your cousin Zhao Xiaomin." ”

"yes, don't underestimate that clue. Officer Wang also helped Gu Chen explain: "The distribution of plants can be traced, although this Ding Ping is the head of the Tao, but how credible it is, we have to investigate before we can draw conclusions." ”

For ordinary citizens like Bai Xiaolan, of course, they don't know what these limited clues can bring to the police.

After all, this kind of small clue is basically negligible.

But for the police, looking for clues should start small, use small clues as points, connect them together, and finally find out the problem.

Gu Chen saw that Bai Xiaolan had doubts, and said: "This kind of pollen is not common, so I am sure that the distribution of this plant in Jiangnan City will not be too much, as long as we know that these pollen come from that kind of flower, and according to the distribution of this flower, we can find out where Ding Ping has been." ”

"Really?" Bai Xiaolan was very weak to listen to Officer Wang's explanation, but as soon as she heard Gu Chen's explanation, she immediately regained her confidence, and her whole person was so excited that she hurriedly bowed and said, "Then please." ”

"What is this for?" Gu Chen helped her up and said, "You are my friend, your cousin is out of touch, we will definitely go all out, this is our duty, there is no need to be so polite." ”

Lu Weiwei touched her gurgling stomach and couldn't help but say, "Senior Brother Gu Chen, Lao Wang, it's already past dinner, why don't we go and fill our stomachs first?"

"Don't worry, there's dry food in the car, I bought it. Bai Xiaolan hurriedly said: "When you go up just now, I will go and prepare dry food and water, if you can cope with it, if not, then I will invite you to a nearby restaurant for a meal?"

"In that case, let's not waste time, the case is important. Gu Chen directly chose to eat dry food and said: "Zhao Xiaomin has been missing for two days now, and if she is not found for one more minute, Zhao Xiaomin will be more dangerous, so we have no time." ”

"I agree with Senior Brother Gu's opinion. Lu Weiwei completely stood in Gu Chen's position and said, "I have to find Zhao Xiaomin immediately." ”

"I know a well-known biologist in Jiangnan City, who has studied all kinds of plants growing in Jiangnan City, and has also participated in the compilation of famous plant encyclopedias in China, I think he should be able to help. Officer Wang also showed his connections.

After all, having been in the police force for many years, this good network cannot be accumulated overnight.

Gu Chen looked at Bai Xiaolan's anxious appearance, but still smiled very easily, and said, "Then let's go, go directly to the biologist and ask him to help take a look." ”

With that, several people also got into the car and drove directly to the door of the biologist's house.

Because of the greeting in advance, there was only three knocks on the door before someone opened the door.

A white-haired old man looked at a few people with a smile at the moment.

"Xiao Wang, are you here?"

"Professor He, this time there is a lot of work. Officer Wang said.

"You're welcome, there's something to say. Professor He brought a few people into the room and shouted into the room, "Old woman, there are guests at home, come out and make a cup of tea." ”

"Okay. The old lady agreed very happily and walked out with a smile on her face.

"Professor He, the situation is urgent, please help us take a look, what are the ingredients of these pollen?" Gu Chen hurriedly took out the evidence collection bag and handed it to Professor He.

"Wait a minute. Professor He walked into the room and turned on the electric light and the desk lamp in turn.

Then he put on a pair of white gloves, began to pour the pollen with soil in the evidence bag on a piece of white paper, put on reading glasses, held a magnifying glass, and began to observe seriously.

"You pollen...... It's rare in Gangnam City. ”

"Professor He knows this kind of thing?" Gu Chen was overjoyed.

Professor He took out a pair of tweezers from a drawer, held the pollen and asked, "Where did you get them?"

"Removed from the sole of a suspect's shoe. Lu Weiwei smiled happily.

"Has this suspect been to the suburbs?" Professor He asked tentatively.

Gu Chen's eyes lit up, and he said with a vague "um", "We think she has been, but this suspect doesn't admit it." ”

"This is easy to do, I found the whereabouts of the missing person, and the rest is not a problem, I am afraid that the matter will be done, but no one will be found, then it will be embarrassing. Professor He also scratched his head again.

"We don't have to think about it for now, trial and error also cost money, but now we have to know how this plant is distributed. Gu Chen couldn't help but urge, and then leaned closer.

After a busy day, I can finally find a cat under Ding Ping's soles, if the case can't be broken through, it will be deadlocked.

Mainly considering Zhao Xiaomin's survival problem.

Bai Xiaolan's eyelids jumped: "Professor He, just take a look." ”

"Don't worry, it will take time. Professor He picked up the pollen in the tweezers and carefully identified it with a magnifying glass, and his eyes suddenly froze.

"How's that?" asked Officer Wang.

"Don't worry, it's not so fast, I'll have to take another look at the microscope. After putting down the magnifying glass, Professor He walked over to the bookshelf and retrieved a microscope wrapped in a foam bag.

"Does this thing need to be observed with a microscope?" Officer Wang thought it would be easy, but now it seemed that he was wrong.

"Because the pollen itself is small according to the information in the pollen, it takes a microscope to see its structure. Gu Chen also added on the side.

Professor He raised his eyebrows and said, "You also know this?"

"I understand a little bit. Gu Chen said, "I learned about it in the library." ”

"Hehe, it turns out that you police also have to be proficient in everything. Seeing Lu Weiwei and Bai Xiaolan helping to unpack the outer package, Professor He couldn't help but smile and said, "What you just said is also right, but different plants have different pollen shapes. ”

Professor Ho is right. Gu Chen was not idle, and continued: "According to the shape and size, symmetry and polarity of pollen, the structure of pollen walls and surface carvings, etc., the family, genus and species of plants can be identified. ”

"I just have never seen this kind of pollen, so I have to ask a professional to help identify it, but Senior Brother Wang said that in the entire Jiangnan City, you are the only one who is highly respected, so I have to find you, Professor He. ”

"Haha, Xiao Wang, that's a slap on my ass, do you believe this?" Professor He listened to it with a smile in his heart, and said: "The pollen of most plants is easy to collect and can be preserved for a long time without losing vitality. ”

"And there will be some specific plants growing in different areas, and if the flower seed information on the suspect's body matches the plants at the crime scene, it can be concluded that the suspect has been present at the crime scene. ”

Professor He thought that it would be a wise choice for Gu Chen to use this method to find the suspect or the whereabouts of the missing, and couldn't help but smile excitedly: "You are already very good, at least you can name some of our biology topics, which shows that you are also involved in this aspect." ”

After debugging the microscope, Professor He glanced at Officer Wang beside him and asked, "Xiao Wang, you police officers now need to have biological knowledge?

"Hey, hey. Officer Wang scratched his head embarrassedly and said, "Keep pace with the times, keep pace with the times, as long as all the knowledge that is helpful to the case, we police officers should learn more." ”

Seeing that Professor He had entered the working state, Officer Wang said again: "For example, in biology, I will need Professor He's help in the future." ”

"Well said. While using a microscope to observe the structure of pollen, Professor He picked up a pencil and drew on the manuscript paper.

After a period of repeated comparison and research, Professor He suddenly smiled at the corner of his mouth: "Haha, congratulations, I already know the variety of this flower."

"Really?" Lu Weiwei and Bai Xiaolan almost said in unison.

Professor He nodded, and said, "Not only do I know the varieties of flowers, but I also know that there is only one place for this kind of flower in Jiangnan City. ”

"Is there only one place?" Officer Wang was also quite surprised when he heard this: "That's easy to do, bring our people, and you can find it in minutes." ”

Bai Xiaolan was nervously rebounded, and said even more nervously: "Professor He, then tell us quickly, where is this place?"

"In the north of Jiangnan City, there is a road to the temple, I don't know if you know clearly?" Professor He asked.

"Yes, I've been to that place. Gu Chen said.

"Good. Professor He nodded, and said, "Fifteen miles to the east, there is a lake over there, and this kind of flower is distributed around the lake. ”

"I'll go. Officer Wang said just now that it was very easy to do, but now that he thinks about it, he regrets it a little, and he wants to retract what he just said.

"Professor He, do you mean ...... These flowers are scattered around the lake, right?" asked Officer Wang.

"What do you think?" said Professor Ho.

Officer Wang frowned slightly, not knowing whether to refute or not?

......
