The sound of a key being used to open the door came from outside. Gu Chen, who was about to leave, stopped again and stopped at the door.
The door was pushed open, and a middle-aged woman with glasses and a slightly out-of-shape figure walked in feebly: "Husband, have you cooked dinner? I..."
When the woman saw Gu Chen, she couldn't help but blink. Then she saw Lu Weiwei and Officer Wang walking over. Her heart suddenly skipped a beat, and she looked ahead in confusion.
First impression: Did I go to the wrong room?
But think back.
If it's someone else's house, why can my key open it? Can all doors of residents' houses be opened with keys?
It has happened before that a resident who went to the wrong house and used a key to open another door suddenly evolved into a key that can open all doors.
This kind of turmoil happened for a while, but it stopped after the locks were 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 door and quickly explained to the middle-aged woman: "Home... there are guests at home."
"Oh." The middle-aged woman looked at Gu Chen, Lu Weiwei and Officer Wang, and seemed to feel an invisible pressure from the eyes of the three of them.
But what the pressure is, the middle-aged woman cannot tell at all.
"Hello, I am Gu Chen, a police officer from the Criminal Investigation Team of 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 to report her family name.
"Oh." This was the first time for the woman to see the police at home, and she felt a little uncomfortable for a while.
"Huan... welcome to my home, do you have anything to do with my husband?"
"Actually... I'm here to find you too," Lu Weiwei said.
"Looking for me?" The middle-aged woman was stunned for a moment, looked at a few people with evasive eyes, and said, "Why are you looking for me? I don't seem to have done anything wrong, right?"
"We would like to know about Zhao Xiaomin from your company." Officer Wang also said directly: "Zhao Xiaomin has been missing recently. Do you know?"
"Ah? Zhao Xiaomin is missing?" The middle-aged woman put on a surprised face, blinked and said: "She...how did she disappear? Didn't she resign?"
Lu Benxiong sighed and said: "A Ping, don't stand at the door, come in and talk."
"Oh, okay." The middle-aged woman nodded, then put her bag on the shoe cabinet, then took off her high heels, put on slippers and walked into the living room.
After everyone sat down again, Officer Wang and Lu Weiwei looked at Gu Chen instinctively.
But at this time, Gu Chen was half a beat slower than everyone else, lingering at the door for a long time before walking over.
"Start?" Lu Weiwei looked at Gu Chen and asked.
Gu Chen nodded, opened the law enforcement recorder again, and held the transcript in his hand.
"Hello, please provide your name, age and ID number." Gu Chen said.
"I...my name is Ding Ping. I am 36 years old. My ID number is..."
After Ding Ping finished speaking, he asked one more question: "Do you want to investigate me?"
"It's not about investigation." Gu Chen looked up at Ding Ping and asked, "Have you been anywhere after get off work?"
"I...I didn't go anywhere? Haha, where can I go?" Ding Ping seemed very nervous.
Gu Chen nodded and asked again: "In other words, you go home directly after get off work?"
"Yes." Ding Ping said.
"Then what's your means of transportation home?" Gu Chen asked again.
"Yes...it's an imported car. I usually drive it home."
"That means you haven't been anywhere outside the city after get off work, right?" Gu Chen's eyes were particularly sharp, making Ding Ping at a loss.
"No...that's right, I drove home after get off work and didn't go anywhere."
"But why is there dirt on your leather shoes?" Gu Chen didn't like to mince words with her, so he directly stated his suspicions.
This stunned Ding Ping, and it took her a long time to react: "Oh, you mean it's about mud? That's... that was on the way home. I didn't go directly to the garage to pick up the car, but
I walked across a lawn and a dirt slope to go shopping, and the dirt on my shoes may have been there at that time. I swear, I really didn't go anywhere."
"Got it." Gu Chen wrote it exactly as it was.
Lu Weiwei said: "Then can you tell us about Zhao Xiaomin? Including her character."
"Zhao Xiaomin? What can she say? She is pretty, very willful, and her job is pretty good, but she doesn't like to work overtime and she doesn't take much discipline."
"Do you know that Zhao Xiaomin is your husband's ex-girlfriend?" Gu Chen also asked directly.
Lu Benxiong on the side quickly coughed twice, turned his head elsewhere, and pretended not to hear.
Ding Ping glanced at Lu Benxiong, and her expression suddenly changed: "I only found out recently, but my husband has never mentioned it to me."
"Then what's your attitude? Does Zhao Xiaomin's loss of contact this time have anything to do with you?" Gu Chen asked again.
"It's unfair. Why does Zhao Xiaomin have anything to do with me when he loses contact? I didn't say anything. Zhao Xiaomin resigned on his own. He probably saw me embarrassed at work, so he left."
No matter how Gu Chen, Lu Weiwei and Officer Wang inquired, Ding Ping seemed to have everything right and firmly held the moral high ground.
Just because she knew that Zhao Xiaomin and Lu Benxiong were ex-boyfriends, Ding Ping described herself as the victim.
In her opinion, it was okay for her husband to lie to her. Even her direct female subordinates also lied to her, and she felt that she was a fool.
So when the police questioned Ding Ping, Lu Benxiong said nothing and simply sat there blankly.
"Comrade police, I am just a housewife." Ding Ping still answered positively, but it did not help at all in solving 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 instantly and said hurriedly: "It's getting late, we should leave."
This chapter is not over yet, please click on the next page to continue reading the exciting content! "Why don't you stay for dinner? I'll ask Benxiong to cook some good dishes." Ding Ping saw that the three of them wanted to leave, and she began to become polite.
.
"No, I'm disturbing you two." Officer Wang also waved his hand and refused.
After the three people left, they returned directly 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 is it? How is it? Have you found any clues?"
"Not yet. Judging from what Lu Benxiong and his wife said, there doesn't seem to be any so-called doubts." Officer Wang paused and said, "But we are not completely without clues. Gu Chen seems to have discovered something."
"Gu...Gu Chen, I know you have good observation skills, but have you found anything suspicious? Can you find my cousin?" When Bai Xiaolan spoke to Gu Chen one-on-one, her voice was obviously much more polite.
.
Gu Chen raised his eyebrows and frowned, without saying a word, but took out a packet of pollen with some soil in a transparent evidence bag.
"What...what is this?" Bai Xiaolan was stunned for a moment, and after getting closer and observing for a long time, she still didn't know what Gu Chen meant.
"This is some dirt I scraped off the soles of Ding Ping, Lu Benxiong's wife. The pollen is hidden in the dirt." Gu Chen took back the evidence bag in his hand.
"Could it be...that this is also called a clue?" Bai Xiaolan was doubtful.
It feels like it's just some pollen. If this is called a clue, then to find this kind of pollen, wouldn't it be like looking for a needle in a haystack?
Lu Weiwei didn't think so and said, "Since Junior Brother Gu can collect these pollen, it means that the place with this kind of pollen is most likely the location of your cousin Zhao Xiaomin."
"Yeah, don't underestimate this clue." Officer Wang also explained to Gu Chen: "The distribution of plants can be traced. Although what Ding Ping said is clear and logical, how credible is it?
How high it is, we have to investigate before we can draw a conclusion."
For ordinary citizens like Bai Xiaolan, of course they don't know what these limited clues can bring to the police in handling the case.
After all, such small clues can basically be ignored.
But for the police, looking for clues should start small, use small clues as dots, connect them together, and finally find the problem.
Seeing Bai Xiaolan's doubts, Gu Chen 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 what kind of flower these pollen comes from, and based on this
From the distribution of flowers, you can find where Ding Ping has been."
"Really?" Bai Xiaolan felt helpless after hearing Officer Wang's explanation, but as soon as she heard Gu Chen's explanation, she immediately regained her confidence. She was so excited that she quickly bowed and said, "Then please."
"What are you doing?" Gu Chen helped her up and said, "You are my friend. Your cousin has lost contact. We will do our best. This is our responsibility. There is no need to be so polite."
Lu Weiwei touched her growling stomach and said involuntarily: "Junior brother Gu Chen and Lao Wang have already passed the meal time. How about we go fill our stomachs first?"
"Don't worry, there is dry food in the car, I bought it." Bai Xiaolan said quickly: "When you went up just now, I went to prepare dry food and water. If you can handle it, if not, then I will ask you to go to a nearby restaurant to eat.
A meal?”
"In that case, let's not waste time. It's more important to handle the case." Gu Chen directly chose to eat dry food and said: "Zhao Xiaomin has been out of contact for two days now. If she is not found for one minute, Zhao Xiaomin will be in more danger, so
, we have no time."
"I agree with Junior Brother Gu." Lu Weiwei stood completely on Gu Chen's side and said, "We must find Zhao Xiaomin immediately."
"I know a well-known biologist in Jiangnan City. He has done a lot of research on various plants that grow in Jiangnan City. He also participated in the compilation of a famous domestic plant encyclopedia. I think he should be able to help."
Officer Wang also showed off his connections.
After all, having been in the police force for many years, such good connections cannot be accumulated overnight.
Seeing Bai Xiaolan's anxious look, Gu Chen smiled easily and said, "Let's go, go directly to the biologist and ask him to help."
With that said, several people also got in the car and drove directly to the door of the biologist's house.
Since I had said hello in advance, the knock on the door only rang three times before someone opened the door.
A white-haired old man was looking at a few people with a smile.
"Xiao Wang, are you here?"
"Professor He, you'll have a hard time this time." Officer Wang said.
"You're welcome, come in if you have something to say." Professor He brought a few people into the room and shouted into the room: "Old lady, there are guests at home. Come out and make a cup of tea."
"Okay." The old lady agreed readily 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 quickly took out the evidence collection bag and handed it to Professor He.
"Wait a moment." Professor He walked into the room and turned on the electric light and table lamp in sequence.
Then he put on a pair of white gloves and began to pour the pollen with soil in the evidence collection bag onto a piece of white paper. He also put on reading glasses, held a magnifying glass, and began to observe carefully.
"Pollen like yours... is rare in Jiangnan City."
"Professor He knows this kind of flower?" Gu Chen was overjoyed.
Professor He took out a pair of tweezers from the drawer, held the pollen in his hands and asked, "Where did you get it?"
"Taken 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, he said a vague "hmm" and said, "We think she has been there, but the suspect doesn't admit it."
"This is easy to handle. If we find the whereabouts of the missing person, everything else is no big deal. I'm afraid it would be embarrassing if the matter is solved but the person is not found." Professor He also scratched his head again.
This chapter is not over yet, please click on the next page to continue reading! "Don't think about this for now. Trial and error also costs money, but now we must know how the distribution of this plant is." Gu Chen couldn't help but urge, and then relied on
Even closer.
After a busy day, I finally found something fishy under Ding Ping's shoes. If the case cannot be broken through, it will reach a deadlock.
Mainly considering Zhao Xiaomin's survival issue.
Bai Xiaolan's eyelids twitched: "Professor He, just take a look."
"Don't worry, this will take time." Professor He picked up the pollen with tweezers and carefully identified it with a magnifying glass. His eyes suddenly froze.
"How is it?" Officer Wang asked.
"Don't worry, it's not so fast. I have to get a microscope to take another look." After Professor He put down the magnifying glass, he walked to the bookshelf and took out a microscope wrapped in a bubble bag.
"Do you need to use a microscope to observe this thing?" Officer Wang thought it was easy, but now it seems that he was wrong.
"Because according to the information in pollen, the size of pollen itself is very small, so you need to use a microscope to see its structure clearly." Gu Chen also added on the side.
Professor He raised his eyebrows and said, "Do you know this too?"
"I know a little bit about it." Gu Chen said, "I learned about it in the library."
"Haha, it turns out that you policemen have to be proficient in everything." Seeing Lu Weiwei and Bai Xiaolan helping to unpack the outer packaging, Professor He couldn't help but smile and said: "What you just said is right, but different plants have different shapes of pollen.
different."
"Professor He is right." Gu Chen was not idle and continued: "Based on the shape, size, symmetry and polarity of the pollen, the structure of the pollen wall and surface carvings, etc., the family, genus and genus of the plant can be identified.
kind."
"I have never seen this kind of pollen, so I have to ask professionals to help identify it. But Senior Brother Wang said that in the entire Jiangnan City, you are the only one with high moral standards, so I must find you, Professor He."
"Haha, Xiao Wang is trying to flatter me, do you believe this?" Professor He felt pleased with himself, and added: "The pollen of most plants is easy to collect and can be stored for a long time without losing its vitality."
"And some specific plants will grow in different areas. If the flower species information on the suspect matches the plants at the crime scene, it can be concluded that the suspect has appeared at the crime scene."
Professor He thought that it would be a wise choice for Gu Chen to use this method to find suspects or the whereabouts of missing persons. He couldn't help but smiled excitedly: "You are already very good. At least you can tell us something about our biology."
Expertise in this field shows that you are also involved in this field."
After adjusting the microscope, Professor He glanced at Officer Wang next to him and asked: "Xiao Wang, do you police officers need to have biological knowledge now? Not bad, good, obviously improved than before!"
"Hehe." Officer Wang scratched his head in embarrassment and said, "Keeping pace with the times, keeping pace with the times. As long as we have any knowledge that is helpful to the case, we police officers should learn more."
Watching Professor He get into working mode, Officer Wang added: "For example, in biology, I will need more help from Professor He in the future."
"Easy to say." Professor He used a microscope to observe the structure of pollen, picked up a pencil, and started drawing on the manuscript paper.
After a period of repeated comparison and research, Professor He suddenly smiled: "Haha, congratulations, I already know the variety of this flower.
"Really?" Lu Weiwei and Bai Xiaolan said almost in unison.
Professor He nodded and said, "Not only do I know the varieties of flowers, I also know that there is only one place where this kind of flower is found in Jiangnan City."
"There's only one location?" When Officer Wang heard this, he was quite surprised and said, "That's easy to do. Bring our people and we can find it in minutes."
Bai Xiaolan was nervous and said even more nervously: "Professor He, tell us quickly, where is this place?"
"In the north of Jiangnan City, there is a road leading to the temple. I wonder if you know it?" Professor He asked.
"I know, I've been to that place." Gu Chen said.
"Very good." Professor He nodded and added, "Fifteen miles to the east, there is a lake over there, and these flowers are distributed around the lake."
"I'll go." Officer Wang said it was easy to handle just now, but now he felt a little regretful and wanted to take back what he just said.
"Professor He, do you mean...that this kind of flower is distributed around the lake?" Officer Wang asked.
"Then what do you think?" Professor He said.
Officer Wang frowned slightly, wondering whether he should retort?
