Forensic pursuit

The underground parking lot with a few dim white lights flashing was empty and silent. After a long time, accompanied by a mechanical female voice, "The first floor is here", two figures walked out, and the surroundings became more angry.

Chu Wanning sat back in the cab with sharp eyes.

Why did Meng Ziqiao understand Liu Xiaorou's behavior in early March, but followed and saved the video at the end of March?

Two possibilities: First, Mencius expressed understanding for Liu Xiaorou on the surface, but secretly held a grudge against Liu Xiaorou, suspiciously followed him, and sent the video secretly shot in late March to the police, just to confuse the public.

Second, there are other details that Li Yunsheng did not explain. Mencius has little evidence and hopes to rely on the police to find the murderer.

At this moment, Nie Fanxin suddenly said, "Sister Wan Ning, Liu Xiaorou didn't wear her wedding ring at the dinner party on the night of March 3th."

"What?" In the hospital office before, the position of Liu Xiaorou's hands was not obvious, and the two of them didn't look carefully.

"Here, zoom in." In the photo, Meng Ziqiao put his arms around Liu Xiaorou's waist, and Liu Xiaorou's hands were on Mencius's.Nie Fan paused for two seconds, found out the photos collected from neighbors in the afternoon, checked them one by one, and gave Chu Wanning a look, "We focused on the deceased Liu Xiaorou, and ignored Mencius Qiao, his marriage Wear the ring from beginning to end."

Chu Wanning understood her meaning in seconds: "So according to you, men are sometimes even more jealous than women. If he minds Liu Xiaorou's contact with Li Yunsheng, he won't wear a wedding ring at all."

Nie Fanxin recalled the scene when he met Meng Ziqiao: "He is a person who pays great attention to details. His face is clean and fresh, without stubble. The shirt he wears under his white coat has the four buttons on his left and right wrists fastened meticulously."

"So why didn't Liu Xiaorou wear a wedding ring, and why did Mencius follow Liu Xiaorou at the end of March?" Chu Wanning asked Nie Fanxin and at the same time asked herself based on clues. She is currently stuck in the "net" and can't get out, and she feels that she is not comprehensive enough.

Nie Fanxin picked up the charging cable and connected it to the phone, and said, "We should be missing one of the key links. However, both questions can be directly handed over to Meng Ziqiao to answer."

"Well, and..."

The two said in unison: Check Qiao Liyi. (Neighbor on the 4th floor)

After all, people are not made of iron. After intense work, you must get enough rest so that your energy can recover.Nie Fanxin was not assigned to guard tonight, so Chu Wanning drove her back.

There was no words along the way, and the quiet carriage could only hear the occasional sound of the traffic light system shifting gears.Chu Wanning chose the autopilot mode, folded her arms and looked ahead. If she hadn't turned her head to drink water twice, Nie Fanxin would have thought she had fallen asleep.

Drinking more and more water, Nie Fanxin realized that Chu Wanning's peripheral vision fell on her two or three times, and then quickly turned back.She suddenly realized that Chu Wanning was still the same as when she was a child, too worried about hurting the people she valued, and took everything on her body.It was like this three years ago, and it will still be like this three years later.

So, when the person next to him reached out to touch the mineral water bottle again, Nie Fanxin handed it to her, with a faint smile on his lips: "Sister Wan Ning, didn't you have something to say earlier?"

Chu Wanning gave a soft "um".

Nie Fanxin hinted at her: "No matter what it is, I will accept it."

Chu Wanning pressed her fingers to her temples, trying to calm down the uneasiness caused by too many speculations. She didn't want to see Nie Fan feel uncomfortable, but when she thought about it, the more she delayed, the real harm would be.It's just that she was hesitant about where to start, so Nie Fanxin's words really relieved her worries.

Chu Wanning pursed her lips, her words were extremely sincere: "Fanxin, I'm sorry for that night three years ago."

Even though he knew the result, Nie Fanxin was still stunned, and after a few seconds, he smiled: "Never mind saying I'm sorry, just refuse if you should." Even though being rejected was still a little uncomfortable.

"Fanxin, I have always regarded you as my younger sister."

"It can only be my sister, right?" Nie Fanxin lowered her head slightly, and slowly took out the mineral water bottle that Chu Wanning was lightly holding, unscrewed it for her, and handed it over, "Now Nie Fanxin only takes Chu Wanning As a sister, from the day you knew you had someone you liked, you guessed it wasn't me."

"Fanxin." Chu Wanning's voice was worried.

"I'm fine." Nie Fanxin raised her head, and joked that she should drink water if she wanted to, don't frown, and reached out to shake Chu Wanning's arm.This is when you like it, you dare not make a move, and when you let it go, you don’t dare to make a move, right?

Chu Wanning was successfully amused by her.

"So, if you confirm a relationship with someone you like, you must tell me."

"must."

"It can't be Wan Xiaoyu, right? My heart might not be able to take it, so I have to prepare two red envelopes." Although Nie Fanxin thought so, she didn't say it out loud. That night, she accidentally learned that Wan Xiaoyu should like youngbodies , under the age of 30.And knowing that he likes her, it is illogical to ask Wan Xiaoyu to tell her. Chu Wanning is not that kind of person, unless he realizes it later or slowly falls in love with her later.

Oops, it's too convoluted, emotional matters are really troublesome, Nie Fan made up her mind not to think about it.

When I got home, I passed the study on the second floor after taking a shower. The light inside was still on, and Wan Yi was writing a book in her coat.Nie Fanxin walked up behind her lightly and patted her shoulder lightly.

"Hey."

Wan Yi was terrified, put the back of her hand on her lips and gave a low cough, and smiled at her: "Aren't you afraid of scaring me?"

"I'm sorry, I have a lot of fun." Nie Fanxin sat on the swivel chair beside her, turned half a circle and asked, "What are you doing? It's almost 12 o'clock."

"Liu Xiaorou's child's blood analysis, each piece of blood-stained cloth is ready to be sent up for inspection."

"So troublesome?"

Wan Yi frowned: "Be careful, I hope I can help you."

Nie Fanxin raised his hand and squeezed her shoulder: "Yes, of course I can, my Wanda forensic doctor, go to bed quickly, it won't be too late to do it tomorrow."

"Sleep, sleep right away." Wan Yi clicked the mouse with one hand, and the computer shut down. She turned around and asked concerned, "How about you? How is the progress?"

Nie Fanxin sighed: "It's a mess, the doubts are mainly concentrated on the three men, and why didn't Liu Xiaorou wear the ring two months before his death?"

"No ring? A wedding ring?"

Nie Fanxin nodded: "Yes, we checked the photos of her after a few years of marriage, and they all have rings."

Wan Yi speculates: "Maybe it's because the fingers are swollen in the late pregnancy, so you can't wear the ring?"

Nie Fanxin opened his mouth, looking surprised: "Huh?"

"Oh, what, you don't understand this at first glance."

Nie Fan replied heartily: "I have never eaten pork, and there are quite few pigs running around. You have never eaten pork, but there should be more pigs running around."

The smile on the corner of Wan Yi's mouth deepened: "The metaphor is too strange, pig, pig."

"Simple and easy to understand." Nie Fanxin took out her mobile phone and told Chu Wanning about Wan Yi's conjecture. Then, without waiting for a reply, she pushed Wan Yi, who had just stood up, back to the room to sleep.

The door was gently closed, and Nie Fanxin turned around and walked back to her room.Lying on the big bed, she sorted out the clues again. The chat records between Liu Xiaorou and Li Yunsheng transmitted through the WeChat background showed that Li Yunsheng was the least suspected so far, unless he quickly deleted the chat records after committing the crime; Qiao Liyi was suspected; In late March, she was still following Liu Xiaorou, and she was quite suspicious.

Tomorrow, Lunar New Year's Eve, will be another busy day.

***

The next day, when the blue sky was clear, Chu Wanning organized a short meeting of the criminal investigation team, and then the meeting was adjourned, and each was busy with the work at hand.At nine o'clock, just after the search warrant came out, Chu Wanning took four people, together with the trace inspection of the research institute, and a group of three cars drove to the community where Mencius Qiao lived.

The security guard knew them and let them go straight away. Meng Ziqiao was on vacation today and stood waiting at the door of his house.

Still with a polite attitude, there are shoe covers in the shoe cabinet, and he is planning to help distribute them.

The deputy director of the trace inspection department of the research institute refused: "No, we carry it with us."

Nie Fanxin took the shoe cover from Chu Wanning and put it on, and followed the traces into the house first.Walking into the living room, what is fascinating is a huge wedding photo frame. Liu Xiaorou and Meng Ziqiao look at each other with sweet smiles.

"It's very loving." Chen Anyou whispered in Xiaoliang's ear, which Nie Fanxin just heard.She turned sideways and casually asked Meng Ziqiao like an ordinary chat: "Dr. Meng, Liu Xiaorou's wedding ring was not found during the autopsy by the institute's forensic doctor. I suspect it might be robbery."

She clearly saw Mencius was stunned for a moment, and replied two seconds later: "Xiaorou's fingers are swollen in the late pregnancy, she took them off in February, and they are locked in the drawer, do you need them?"

"No need, thank you." What he said should be the truth. In this case, Li Yunsheng's statement is more credible.As for the matter of paranoia, there are so many people now that it is not the time to ask questions. After all, the two promised Li Yunsheng to keep it a secret.

"Is this photo frame hanging all the time?" Chu Wanning touched the edge of the photo frame with her gloved right hand.

Mencius affirmed: "Well, yes."

"Can I borrow a high stool?"

Mencius said enthusiastically, "There's one in the utility room, I'll help you carry it."

Chen Anyou said at the right time: "Where is it? I'll go."

"Come with me."

In less than a minute, Chen Anyou came out with a high stool and put it under the photo frame, and Chu Wanning stood on it.If you look closely, the surroundings of the photo frame are clean and dust-free, and the back is the same. No matter how clean the owner is, the back should not be taken care of.Chu Wanning moved the high stool to the other side of the Mencius single photo frame, the surroundings of the photo frame are still the same, but the back is covered with dust.

Perhaps Mencius knew about the police visit and re-hanged the wedding photos in advance; it may also be that Mencius paid special attention to the wedding photos, and was meticulous in every detail when cleaning.

Chu Wanning got off the stool and looked at another photo frame, but there was the same problem.As long as it is a single photo of Meng Ziqiao, there must be dust on the back, but the back of the wedding photo and Liu Xiaorou's single photo must be clean and dust-free.

More and more suspicious, Chu Wanning thanked Meng Ziqiao, and carried the bench back to the storage room with her own hands. When she found that the floor of the storage room had just been mopped, her eyebrows frowned instantly: "Doctor Meng, did you just do cleaning? The floor is wet ?”

"Officer Chen overturned the detergent when he was moving the stool. I am really used to staying at home to clean when I am on vacation, so I just dragged it along."

Chen Anyou said truthfully: "That's right, Captain Chu, I accidentally stepped on it."

Chu Wanning nodded, expressing her understanding, and then asked, "Does Doctor Meng have a study room? I have a few words I want to chat with you."

"Yes, of course." No one in the police could talk to witnesses or suspects alone. Chu Wanning glanced at Nie Fanxin, and Nie Fan understood, and followed them into the study one after the other.
