Forensic pursuit

Although technology continues to improve, the surveillance video of the community can only be stored for 30 days from the original [-] days, and it can be stored for three months, but it still does not help.

What happened ten months ago is difficult to visit and collect evidence.Therefore, while the city bureau dispatched elites, it did not put too much pressure on the branch bureau.It's just that the director Zhu Fang, out of face, kept amplifying the pressure and dumping the burden on the Criminal Investigation Brigade, which was tantamount to letting Chu Wanning bear it.

The case must be solved within 7 days. People who stand and talk don't suffer from backaches, but those who run and do things suffer from headaches.

Chu Wanning took them to every corner of the community, and finally knocked on the door to ask.Nie Fanxin no longer avoids Chu Wanning on purpose, but instead actively assists her in the investigation together.

At 8:[-] p.m., they finished their bread in a hurry, took the elevator to the fourth floor, and knocked on the door of the next door to Meng Ziqiao and Liu Xiaorou.

The male host who opened the door was polite: "I'm really sorry, I came back late from the dinner and kept you waiting, please come in."

"Thank you, let's talk at the door." Chu Wanning signaled Nie Fanxin to record.

The male owner folded his arms on his chest and began to talk: "We don't have a deep relationship with Nurse Liu and his wife, but we are a little better than ordinary neighbors. Nurse Liu cooks delicious food, and my wife and I occasionally go to have a meal." Male The owner slid open the lock screen of the mobile phone, found a few photos, and said with a smile, "It's all a big meal, and I feel nostalgic."

In the photo, five people appeared most frequently at the same time. Nie Fanxin looked warily at the man standing on the right side of Liu Xiaorou: "Who is this person wearing the hat?"

"Director Li at 501 upstairs, a colleague of Nurse Liu."

Chu Wanning: "Are you single?" She remembered that only one name was written in 501 on the roster.

"Three years ago, Director Li's wife died of cancer. He should still be single now."

Nie Fanxin continued to ask: "How is the relationship between Director Li and Nurse Liu's family?"

The male host lowered his voice: "It must be closer than Nurse Liu and I. As a colleague, there is an extra layer of relationship. As for whether there are other shady relationships, you need to be investigated by the police."

"What do you mean?" Chu Wanning frowned imperceptibly. Although she hated making unreasonable guesses about other people's conduct, she had to say that sometimes, these guesses were related to the clues to solve the case within a certain range.

"Last Spring Festival, I often saw Director Li and Nurse Liu going back to the community together at night."

Nie Fanxin retorted: "They are in the same department, and they are quite normal together."

"One night, when I walked behind them, I saw Director Li trying to hold Nurse Liu's hand. Maybe Nurse Liu felt someone was there and pulled her hand away."

Chen Anyou roared and asked him, "This is cheating, are you talking nonsense?"

"How could I be talking nonsense?"

"Excuse me." Chu Wanning received the photo from the host and didn't keep any more.They walked into the elevator one after the other, Chu Wanning reached out to slide the photo, paused, and looked at Liu Xiaorou's ring finger: "Xiao Chen, ask Xiao Liang to check Director Li and find time to chat with him. Xin, at the scene of the crime, Liu Xiaorou doesn't have a wedding ring on her ring finger, right?"

"No." The physical evidence was reserved at that time, and Nie Fanxin remembered it deeply.

"In January last year, Liu Xiaorou wore a wedding ring on her ring finger. In the two photos in March last year, she didn't wear it."

Chen Anyou leaned on the elevator handrail: "Did you forget to wear it, or lost it?"

"In the photos that the butler showed us, Liu Xiaorou is wearing a wedding ring." Nie Fanxin said as he took out his phone, "This is the beginning of 49 and 48."

"So, it is very likely that their marriage changed, and Mencius killed his wife and son?" Chen Anyou speculated based on clues.

Mencius's suspicion was brought up, and Nie Fanxin's mind suddenly flashed the picture of the reception room in the hospital in the morning. She tapped the stainless steel handrail lightly with her fingertips and said, "I found a detail that is very strange. When you asked about Liu Xiaorou's physical characteristics, Mencius' Subconsciously support the glasses frame with your hands, and sit back straight."

"I was so busy talking, I didn't pay attention. Mencius made too many petty moves?"

"Suspicious." Upon reaching the ground floor, Chu Wanning walked out of the elevator first, tilted her head and said, "Looking at Mencius Qiao and Director Li, Mencius Qiao is very suspicious, reasoning backwards, Director Li is also suspicious."

Chen Anyou's phone vibrated, and a text was sent, and he immediately relayed: "Captain Chu, Xiao Liang contacted Director Li. He just had the operation and made an appointment for an interview at 9:[-], but there was no one at the hospital."

"Well, you and a few other colleagues are guarding the community, watching Mencius Qiao's every move. Tomorrow, after applying for a search warrant, we will enter the house to search for evidence." Chu Wanning said as he walked out, "Fanxin and I will go there Hospital."

Nie Fanxin was sitting in the co-pilot, feeling the increasing speed of the car, and seemed to be able to predict Chu Wanning's suppressed emotions. She waited for the red light to come, the traffic stopped, and discussed with the other party like a partner for many years: "Sister Wanning, there is no monitoring, The call records can only be found within six months at most, and the scene is too clean."

Chu Wanning sighed: "I know."

"Did Bureau Zhu exert pressure?" At the end of the meeting in the afternoon, Nie Fanxin saw with his own eyes that Zhu Fang called Chu Wanning aside, although he didn't know what was specifically discussed.

Chu Wanning smiled wryly: "How can there be no pressure to investigate the case? Even if Bureau Zhu doesn't give it, facing the family members of the deceased, the pressure will naturally accumulate gradually."

So when he called the deceased's parents in the afternoon, Nie Fanxin saw Chu Wanning leaning on the wall with one hand, his arm trembling slightly.

"Then let's find out the truth as soon as possible and let Liu Xiaorou rest in peace."

After a short 40 seconds, the red light passed, and the green light turned on. Chu Wanning followed the vehicle in front and started with a little helplessness in his eyes: "But you are right, it has been a long time, and the tension at the beginning of the murderer's crime has gradually disappeared. He can hide better, plus he has strong anti-detection capabilities..."

"Don't mention these frustrating words, let's start with Liu Xiaorou's social relations and check them one by one." Nie Fanxin took out the small box in her bag, opened the lid, poured out a piece of chewing gum, and said with a gentle smile, "Chew one, break it down a little bit." pressure."

"Okay." Chu Wanning looked at another red light ahead, braked to slow down, and pursed her lips, as if she had something to say.

"What, Sister Wan Ning?" Nie Fanxin probably guessed what she wanted to say, but she didn't feel particularly uncomfortable, but it didn't matter, "We sisters are chatting, why do we need to cover up and stop talking?"

"Yes." Chu Wanning let go of the brake, turned right into the hospital parking lot, and while looking for a parking space, said loudly, "I'll talk about it later, let's get down to business first."

"Okay." Nie Fanxin subconsciously teased her like she did when she was a child, "But first, laugh."

"Huh?" Chu Wanning started to reverse the car.

"Smile, you look good when you smile."

"Get out of the car." Chu Wanning unbuttoned her seat belt, with a slight smile in her tone.

"That's right, you should be active in investigating the case, and you should have a sunny attitude." Nie Fanxin pushed open the car door, and after feeling relieved, he felt a lot more relaxed.

Is it really true to the sentence: "It's fun to be single for a while, and it's always fun to be single all the time?"

"Hey." Seeing someone standing there, Chu Wanning called her.

"Here we come." Nie Fanxin stepped forward with her long legs, walked side by side with her two or three steps, and said to Chu Wanning with affirmative voice, "The two of us, together with Wan Xiaoyu, the detail madman, there is no case that cannot be solved."

"Okay, there is no case that cannot be solved." Chu Wanning's slightly tense face completely burst into a smile.

The night in the hospital was also unusually quiet, only the emergency ward was filled with people walking around in twos and threes.Chu Wanning and Nie Fanxin took the elevator directly to the sixth floor, and Director Li was waiting for them outside the office of the Director of Cardiac Surgery.

Li Yunsheng, 37 years old, graduated from the top 1 university in China, and is currently the deputy chief physician of the Cardiac Surgery Department of the Affiliated Hospital of Binnan University.He greeted them politely: "Two police officers, please sit inside."

"Thank you." There were many details to ask, but Chu Wanning did not refuse.

"Drink water?" Li Yunsheng entered the door, walked slowly to the corner, opened the bottom box of the water dispenser, and took out two disposable paper cups.

Chu Wanning declined: "No, thank you."

Li Yunsheng turned a deaf ear, poured half a cup of hot water first, then poured half a cup of cold water, turned it into lukewarm water, and said, "Girls should drink more water. The two female police officers have dry mouths. You should listen to the doctor's advice."

……

Sounding like they couldn't refuse any more, the two reached out to take the paper cups.

Li Yunsheng sat on the chair, knew what they wanted to ask, and said directly: "Nurse Liu is the nurse who cooperates best with me among the many surgical nurses. We have a very good relationship. The year before last, Mencius bought a car, and I lent it to Nurse Liu for 10 yuan." Ten thousand."

Nie Fanxin, who was in charge of recording, looked up: "Have you paid back the money?"

"I paid it back, Nurse Liu paid it back in cash on Lunar New Year's Eve last year."

Chu Wanning cut to the chase: "Well, someone saw you and Nurse Liu flirting, and suspected that you had an unusual relationship."

Li Yunsheng frowned immediately, and scolded: "Officer, you can eat indiscriminately, but you can't talk indiscriminately. Nurse Liu has passed away. You are tarnishing her innocence."

Chu Wanning stared closely at the change in Li Yunsheng's expression: "Passers-by are just suspicious. The cause of Liu Xiaorou's death is unknown. It is our greatest respect for her to find the murderer."

Nie Fanxin suddenly received a video from Chen Anyou, she clicked on it and watched it silently under the table.The light in the picture is dim, and the man tried to pull the woman's arm twice, but was pushed away.

Nie Fanxin typed quickly, and asked Chen Anyou, "Where did this video come from?"

"At the end of March last year, Mencius followed me to shoot."

Nie Fanxin pushed the phone to the middle of the table and pressed the play button.

"This..." Li Yunsheng began to hesitate, and the corners of his mouth twitched intermittently, "This has nothing to do with Nurse Liu, it's my personal problem."

Chu Wanning asked: "What's your personal problem?"

Li Yunsheng took a breath and stabilized his mood slightly: "Officer, this is a matter of my privacy, so I don't need to explain it."

When to ask and what to ask, Chu Wanning had a clear mind: "We have reason to suspect that you attempted to court and killed Liu Xiaorou."

"Officer, my family was poor when I was a child, and I vowed to study hard and get out of the mountains. I have been practicing medicine, and the minimum moral issues will not be violated."

Li Yunsheng stared at Chu Wanning's eyes without blinking, and his words were so sincere that the two of them believed his words for a moment.Chu Wanning reacted, and immediately turned to the beginning, moistened her throat, and said in a slower tone than before: "The police talk about evidence, we don't believe what you say."

Li Yunsheng clasped his hands tightly, and the thumb of his right hand kept rubbing the tiger's mouth of his left hand, repeated hesitant movements.

Nie Fanxin seized the opportunity: "If Dr. Li has something to hide, he can choose to trust one of us."

Li Yunsheng covered his face and clasped his hands together: "It's not that I don't believe you, it's because it's ridiculous to say it. As a doctor, he shy away from medical treatment. Without Nurse Liu's repeated persuasion, I must still be in deep pain now."

Nie Fanxin took a sip of water from the paper cup, raised her eyebrows and said, "Doctor Li, relax and continue."

"Haha, it's said that people don't want to deal with police officers and judges the last thing in their life, but in my opinion, the two police officers are very cute." Li Yunsheng also picked up his thermos and sipped slowly.

"I have delusional disorder. My wife and I have been in love since high school. She didn't dislike me for being poor, and stayed with me through the most difficult six years. Later, I moved to a new house, thinking that I could enjoy happiness, but she was diagnosed with advanced liver cancer. I died in three months. I may have become sick from love. I often regarded Nurse Liu as her, called Nurse Liu by her nickname, and called Nurse Liu’s wife. I unconsciously did some bad behavior. At first, Nurse Liu thought I was a pervert , Later, because of trust, and through observation, I speculated that I might be ill. Occasionally, she would accompany me to see a doctor, and Professor Zheng from the Department of Psychiatry of Binnan People's Hospital can testify."

Li Yunsheng showed them the WeChat records.

"Nurse Liu is very kind. I am very grateful to her. How could I hurt her?"

Nie Fan looked through the records heartily, one after another kind words from the heart...

"Doctor Li, can I tell Ziqiao about your illness? He began to suspect me, February 2."

Chu Wanning found the key point: "Doctor Li, Meng Ziqiao knew the specific situation at the end of February?"

"Well, of course I can reply. Nurse Liu communicated with Xiao Meng on March 3, and Xiao Meng also expressed her understanding." Li Yunsheng slid the screen, "Nurse Liu and the others have a good relationship as a husband and wife, so I don't mind. On the night of the 1th, we three This is a group photo for having dinner together.”

In the photo, Li Yunsheng was sitting, and Meng Ziqiao was standing behind him with his arms around Liu Xiaorou's waist. The three of them smiled sincerely.

Li Yunsheng passed the photos and chat records to Nie Fanxin, and finally suggested: "It should not be Xiaomeng, you can check other people."
