Forensic pursuit

Nanyun District and Leilong County belong to the same level, and the public security system is naturally independent of each other. Chu Wanning has no right to interfere with the drowning case six years ago, and can only report to the Municipal Bureau through Zhu Fang.At 6 o'clock in the evening, the Criminal Investigation Detachment of the Municipal Bureau formed a temporary investigation team, assisted by the Criminal Investigation Brigade of Leilong County.The Nanyun District Criminal Investigation Brigade is responsible for investigating the case of Cao Hai's death by hanging.

Special case office, although the two groups investigate separately, some clues can be shared.Nie Fanxin and his party stepped into the office of the criminal investigation brigade one second ago, and Chu Wanning knocked on the door with the dossier of Cao Hai's abandonment case the next second.

"Meeting next door."

She walked fast with her long legs, and when Nie Fanxin pushed open the door, the screen of the all-in-one machine showed the video recorded by the surveillance at the entrance of Leilong County Children's Welfare Institute.Chu Wanning pressed the play button, and the quiet night was silent for a moment in the screen. At 17 seconds, a man wearing a fisherman's hat and a black down jacket appeared in the camera holding Cao Hai. At 23 seconds, he put down the boy and hurried away.

"This person doesn't look very tall, he shouldn't be Cao Bin." Chen Anyou took a closer look.

Chu Wanning paused the video: "Yes, according to the reference of the street lamp next to it, the police station estimated that the man's height is about 175cm."

Xiao Liang sighed: "How long will the child stand alone at the door in such a cold day?"

"Continue to look back." The screen fast-forwards, starting at 37 minutes and 19 seconds, Cao Hai is crying. At 40 minutes and 23 seconds, probably hearing crying, the iron door behind him opened, and a man in a security uniform picked him up, looked around, and finally took him back to the orphanage.

Chen Anyou gritted his teeth: "For 40 minutes, who did it? It's not as good as a beast."

"Cao Bin's bank statement is problematic." Nie Fanxin, who had been silent all this time, finally spoke.

Chu Wanning: "Speak."

"Every time how much money is transferred from Xu Si's account, how much money will be transferred to Cao Bin from another account in two days. For example, on February 2036, 2." Nie Fanxin connected Bluetooth, and the screen displayed a photo. She continued, " On the morning of that day, Xu Si spent 7 yuan on his account, and on February 5000, Cao Bin earned 2 yuan on his account.”

"What's going on?" Chen Anyou was confused.

"After receiving 5000 yuan, he transferred another 800 yuan to that person."

Xiao Liang guessed: "Hire someone to act?"

"It's possible." Chu Wanning looked at ten lines at a glance, and scrolled down the remaining screenshots of the bank's flow, doing the same operation with minor differences.

"I'll contact Cao Bin." Nie Fanxin grabbed the phone and walked out of the conference room before anyone on the stage nodded.She rarely has such strong emotions, but every time she thinks of Xu Si's 41-year-old age, she is willing to risk her life with a man who thinks she respects her as a guest, but she doesn't know the fact that she is kept in the dark, she feels uncomfortable and panics.

The window of the interrogation room on the right side of the office was clean, and the linen curtains were not drawn.Nie Fanxin was sitting in front of the computer with her eyes closed, holding the phone in her left hand, waiting for the call to connect.

"Hello, Officer Nie." Cao Bin greeted her, saving her number.

Nie Fanxin didn't intend to make a detour, and asked straight to the point: "Why did you abandon Cao Hai?"

"I don't understand what Police Officer Nie means." He sounded calm on the surface, but Nie Fanxin had already noticed that his voice had risen significantly.

"In 15 years, you spent a total of 35.2 yuan to find Cao Hai, right?" During the meeting, she added up all the expenses that Xu Si noted.

"almost."

"So your income is 33.4 yuan, am I right?" Nie Fanxin took a deep breath to suppress the restlessness in his heart.

"Me, the little money I made from buying funds."

"Which fund? How much profit each time?" Nie Fanxin looked serious. Although he couldn't see anyone, his tone was enough to scare the other party. "Cao Bin, don't try to lie in front of the police."

The other end of the microphone suddenly fell silent, only the sound of each other's breathing could be heard.

"Also, you have another ICBC account ending in 4209, to whom do you regularly transfer 15 yuan around the 5000th of each month?" Nie Fanxin discovered the details and had more guesses.

"I……"

"You don't need to say it now, but after the application, we will know her name clearly." Nie Fanxin can't inquire about the other party's history privately, and needs Chu Wanning's consent and a "Case Handling Cooperation Letter" before she can inquire through the bank relevant account information.

Cao Bin was short of breath: "Officer, if you have a child born with a disability, you will definitely collapse too."

"Then what? Let him fend for himself? Tigers don't eat their babies, Cao Hai is your and Xu Si's child." Nie Fanxin never felt that having children was a must-do task, but she should be responsible for them after birth.

Cao Bin explained in a hoarse voice: "After Xiaohai was born, we spent 10 yuan, and the subsequent annual treatment costs at least 6 yuan."

"Where is Xu Si? Have you given up?" Nie Fanxin searched for entrepreneurs who funded Cao Hai, and asked him to compare his own bad behavior. "You should thank Ms. Cao Yuan, Cao Hai can live for 15 more years. She donates to Binnan every month. There are 50 dwarfism patients in the city, and Cao Hai happens to be one of the lucky recipients."

"Yes... is it?"

"Let's get down to business, do you admit that you hired someone to deceive Xu Si?" Nie Fanxin gently stroked the phone case with her index finger, sorting out the details in her mind and trying her best to control her emotions.

Cao Bin argued: "I don't use the cheated money, I keep it."

The pure white light scattered on the floor, refracted back, and hit Nie Fanxin's side face.Her voice suddenly raised, and she asked: "And then transfer 5000 to irrelevant people every month?"

Nie Fan could clearly hear Cao Bin swallowing saliva because of nervousness, and Nie Fan had a complete seizure after receiving two new messages, "Who is Liang Lianli? Do you need me to remind you?"

"Officer, you, stop talking, I, I..." Cao Bin began to speak incoherently.

Nie Fanxin clenched her fists and blurted out: "He is from Dachuan County, Shanzhou Province. He is 35 years old. He is married and has children. His husband Cao Bin and his son Cao Yang are 11 years old. Bigamy, do you know? Why not divorce? Why? To drag Xu Si? She is still pregnant with your child!"

Now Cao Bin is like a dying fish, with his mouth open, not daring to make a sound.

"Tomorrow, come to the police station and surrender. The crime of abandonment is added to the crime of bigamy, and there is also the crime of fraud."

Cao Bin finally spoke: "Police officer, can you not tell her, wait..."

Nie Fan was furious: "What are you waiting for? Xu Si has the right to know the truth." After nearly four years of work, she has seen many scumbags, but this is the first time she has seen a scumbag with a shameless face and first-class acting skills like Cao Bin.

After the call ended, Chu Wanning, who was leaning against the door and listening to the inquiries, was ready to come in and interrupt at any time, knocked on the door lightly, and threw her a bottle of unopened mineral water: "Go home early, and we will meet in the parking lot at 8 o'clock tomorrow. Go to Leilong County."

Nie Fanxin unscrewed the bottle cap, filled a small bottle of water, and asked, "What about Cao Bin?"

"Leave the detailed investigation of Cao Bin's abandonment, bigamy, and fraud to Xiao Liang. You and I, as well as Chen Anyou, will go to Leilong County." Chu Wanning closed the door of the interrogation room, paused briefly on the lock, and then looked at Elsewhere, "The Municipal Bureau found a clue half an hour ago, but the central figure of the clue, Peng Zhan, the former vice president and logistics director of the orphanage, committed suicide."

"suicide?"

"Cutting the wrists, the details need to be dissected by a forensic doctor."

Nie Fanxin walked beside her and asked, "What's the clue?"

“市局30位同事浏览所有监控录像，无意间发现在案发下午1点10分离开福利院，3点29分返回福利院。雷龙县公安分局的询问笔录记载他去批发市场买文具，但是查阅财政发票，没有2044年7月2日落水当天的明细。”

"So the logistics director lied."

Chu Wanning nodded: "Yes." Walking out of the complex, she turned around and said, "I will tell the others in the car tomorrow, go back quickly."

"Oh." Nie Fanxin's tense nerves had not been completely released, and his expression was solemn.

It's rare for Chu Wanning to joke with her: "Don't you want Xiao Yu? I didn't expect you to be a workaholic."

When Wanyi was mentioned, Nie Fanxin's frowning brows loosened slightly, and she asked her back: "Sister Wan Ning, what about you? Don't you want Pei Xiaorong?"

The two laughed at the same time.

Relaxed, Wan Yi's frown and smile completely replaced the displeasure that Cao Bin had brought to her just now, Nie Fan stepped on the gas pedal, only wanting to show up at home in a second.

----------------------

As the night approached, the person who took a shower quietly pushed open the bedroom door, and when he looked up, he saw Wan Yi who was half leaning on the bed.She turned her plain face to the sky, and the side face carved out of jade and ice was more and more softly illuminated by the warm yellow wall lamp.As a result, Nie Fanxin forgot to take a step for a while, and just stayed where he was and watched for a moment.

It was Wan Yi who called her: "4 minutes and 07 seconds, what are you thinking while standing there?"

"Ah, sleepy." To prevent the other party from discovering his thoughts, Nie Fanxin stepped forward in three steps and two steps, and fell headlong into the bed.

"Come up and lie down when you're sleepy." Wan Yi rubbed the back of her neck with no effort, and picked her up.

"Wan Xiaoyu, what are you looking at?" Nie Fanxin blushed and lifted the thin quilt, sat next to her and changed the subject.

"I just received the autopsy report from Lao Lin, but I didn't have time to open it."

"Cao Hai's?" Nie Fan became interested and planned to watch it with her.

"Correct."

Wan Yi slipped down the electronic report, brief case and on-site investigation, at 2050:6 noon on June 3, 12, Zhu Yueshan found a skeleton.The center site is located on an ancient tree, on the south side of the east end of the platform (height 49cm, width 1cm, thickness 821cm).Skeleton Axis vertebral fracture, typical features of hanged death, both arms severed at the elbow.After special treatment, it was found that the deceased was suffering from congenital achondroplasia.

"Congenital achondroplasia?" Wan Yi pursed her lips, thought for a moment, and said to herself, "Arms amputated?"

"Yes."

"Fanxin, do you remember that in February this year, we found a cigarette butt at the scene where Liu Xiaorou's body was found?"

"of course I remember."

"The boy who grabbed the cigarette butts is not tall. You lock him on the railing on the ground floor."

"He cut off his right hand and escaped. Then what? Is it related to this case?"

"The man's phalanx has been tested, and it is also congenital achondroplasia."

The author has something to say: The child is lost. According to the documentary, the police track down the criminals who trafficked children. In the case of Cao Hai, the family usually finds it by themselves.

The national marriage information network has not yet been realized, and I don't know why?Do people who want to remarry have a chance?
