Forensic pursuit

At 8:3 p.m., the conference room on the third floor of the complex building of Nanyun District Public Security Bureau was full of police officers in the middle of the first two rows.

Except for Lao Yang, who just became a regular from the auxiliary police, and the three colleagues from the second group of the Criminal Investigation Brigade who had met, Nie Fanxin didn't know anyone else.She sat down in the right seat in the second row and waited for a while before the meeting officially started.

12 people, the third team of the special investigation team formed temporarily, with Chu Wanning as the team leader.She had secret talks with 3 colleagues, each with different tasks, but the ultimate goal was the same.

Although it belongs to the secret investigation, each group, each person does not act alone, and there are powerful forces behind it, criminal investigation, technical investigation, special police...

Liu Xiaorou's case is just a breakthrough, and there are more unknown challenges waiting for them.

"The meeting is adjourned, and everything else remains as usual. Lao Yang and Fanxin will stay here for a while." Everyone received the equipment for positioning and calling, and dispersed separately. Chu Wanning, who was packing up the materials, looked up, "Old Yang, you have rich experience, and Fanxin is young... "

Lao Yang understood, and said with a smile: "Xiao Nie should be particularly relieved, but it's a pity that Xiao Chen and the others have learned badly from some old colleagues."

Chu Wanning: "A good seedling is always a good seedling. Several backbones of the brigade are in the observation period. I hope there is nothing wrong, and I hope there is still time."

Nie Fanxin also echoed, "Brother Liang is fine, reliable; Chen Anyou is short-tempered and quick-tempered, and he is quick when doing business."

Deputy Director Huang of the Municipal Bureau has recently been keeping a close eye on Captain Zhou who was promoted in Nanyun District. The source of a large amount of money is unknown, and it is hard to find definite evidence. Therefore, the old subordinates who are close to him are all under the scope of investigation.

However, the parties involved, as well as all the subjects under investigation, were kept in the dark.Only the monitoring team including Deputy Director Huang and Chu Wanning, who took over as Captain Zhou's criminal investigation team, knew about it.

Chu Wanning picked up a stack of documents and turned off the computer: "Fanxin, Yang Xin's case can't be left behind either. I briefly browsed the interrogation video. Liu Dai must continue to follow up. If Chen Anyou, who is your partner, is too impulsive, change him." Cheng Xiaoliang." The two walked out side by side, and Lao Yang in front helped to open the door, and she continued, "Old Yang, let everyone help share the surveillance video of Liu Dai's rental community, you can arrange it."

Before the new captain passed the selection and took office, Lao Yang also served as the captain of the auxiliary police squadron.

Lao Yang locked the door: "They are watching."

The three of them went downstairs and passed by the canteen. Nie Fanxin scanned the QR code on the window and said, "Sister Meng, a bottle of coffee." She turned around and asked, "What about you? What are you drinking?"

"How could it be possible to treat the youngest one." Lao Yang also went to scan the QR code, "Xiao Meng, the same."

Chu Wanning paid directly: "I'll go back to the office for tea."

Nie Fanxin took back the phone, muttering and complaining: "Miss Wan Ning, the speed is too fast."

Chu Wanning patted her on the shoulder and smiled: "You and Lao Yang are on duty tonight, it's hard work."

Nie Fanxin turned around and said: "Should someone go home early, otherwise every rest is no different from our duty."

Old Yang's childlike heart remained undiminished, and the 40-year-old eldest brother gave a thumbs up playfully: "Xiao Nie's words make sense."

Talking and laughing, they have already returned to the office of the Criminal Investigation Brigade and split up their work. The coffee on Nie Fanxin's right hand will soon run out.During the investigation of criminal cases, surveillance video plays a huge role, which is the key reason why the detection rate is as high as 99%.

Recent videos are marked with dates, but they are long-term, such as more than one month, and they need to browse section by section before confirming the date.

The sky turned pale, and the lights in the office were turned on all night.The auxiliary police colleagues around him had already started snoring. Nie Fanxin put his index fingers on his eyelids and almost fell asleep, but suddenly saw the words 2.1605:37 under the progress bar, and instantly regained his energy.

She took two sips of strong tea, then looked down. At 2:16 am on February 9, Liu Dai appeared in the No. 53 elevator and seemed to be on the phone.Afraid of waking up his colleagues, Nie Fan put on his earphones and switched the volume from mute to normal.

There was a sound of electric current, probably the receiver of the microphone was talking, and then Liu Dai's lazy voice sounded: "Why is it so early, do you have nothing to do?"

"You and old man Wu could have lived with Wu Jie, but you want to occupy the house and not let me sell it."

Nie Fanxin judged the person who was talking to Liu Dai, and frowned suddenly.

"The car at 10:[-]."

"I just paid back 10, and I'm still short of 10. When will you give it to me?"

When Liu Dai walked out of the elevator, Lao Yang was in charge of the outdoor video recording, and it seemed that no one had been found yet.Nie Fanxin recalled Liu Dai's words and recorded key information.

Liu Dai wants to sell the house because he owes 20 yuan in debt. Where does the car go at 10:[-]?

The son's bad attitude has something to do with his mother's overdoting. Even though he couldn't hear Yang Xin's voice, Nie Fanxin could guess.Don't worry, I'm thinking of a way, and so on...

"Xiao Nie, you haven't slept yet?" Lao Yang, who had collapsed at the opposite desk, woke up with a yawn.

"No, what time is it?"

Lao Yang glanced at his phone: "7:32."

Nie Fanxin raised the receiver of the landline with one hand: "Call."

Chen Anyou, who had just arrived at the office, asked, "Who are you calling early in the morning?"

"Wu Jie." Instead of wasting time with Liu Dai, it is better to ask a third person.

Wu Jie is a counselor at Binnan Normal University and has a regular schedule. At this time, the call was connected within 10 seconds, and Nie Fanxin explained his purpose.

"Officer, to be honest, Liu Dai really dragged our two families down. Two years ago, he borrowed the 10 dowry gift from my wedding, and he has not yet returned it; last year he searched my dad's 28 retirement fund; My aunt never agreed."

Nie Fanxin asked, "Who does the house belong to?"

"Liu Dai's name is written on the real estate certificate, but Aunt Yang bought the house when she was young. It stands to reason that he can only sell the house if Aunt Yang nods. But Liu Dai is timid and should not dare to kill anyone."

Nie Fanxin played the call, Chen Anyou recorded it, and she continued, "Do you know where Liu Dai is going on February 2?"

"It's like going back to the old house, on the 28th of the twelfth lunar month, and going up the mountain to worship his dead father."

Wu Jie didn't know the address of the old house, so Nie Fan asked repeatedly, and finally found the old-fashioned stair house only 5 kilometers away from Wangling Mountain.

When the search warrant came out, Liu Dai himself was not notified, and Chu Wanning led the team, and six police officers rushed into the room directly.

"Gloves, foot covers." With two rooms, one living room and one bathroom, Chu Wanning looked around and reminded them.

Chen Anyou looked at the table next to the living room, and said, "The dust is quite thick, and there must be no one living there."

Lao Yang hung up the phone and signaled everyone: "The colleagues from the trace inspection institute will be here soon."

Chu Wanning glanced at the scorched ground, waved her hand and said, "Don't go into the bathroom, wait for the trace inspection."

Chen Anyou also took a look in, and spat: "It's definitely the scene of the first crime, this little bastard, you can't be judged by his appearance."

Not long after, Henjian entered the bathroom, and Nie Fanxin stood outside the door waiting. He looked up and saw Wan Yi, who was wearing a light blue suit and a mask, stepped into the cordon and walked straight inside.

"How did you come?"

"Business." Wan Yi replied simply, her gloved hand was already on the bathroom tile.

What are you saying, it's not a business matter, is there a private matter?

Looking at the traces on the ground, Wan Yi frowned slightly, and asked, "Is the power off?"

A colleague from the Trace Inspection Department replied: "It's broken." He continued, "Wan Forensic, the circuit has been modified, and it is a contact high-voltage device. Just go into the bathroom and turn on the switch next to the sink, and you will get an electric shock."

"This is where the dead fell." Trace inspection had already drawn a human figure on the ground.

"No, look inside again." Just in case, Wan Yi quickly put on the insulating suit prepared by the trace inspection. She won the second prize in the Binnan City Physics Competition in high school and is familiar with the circuit. The remote control is turned on, and the deceased presses the switch again to trigger the high voltage, both of which are indispensable."

Why does it seem like deja vu...

Chen Anyou, who was standing outside the bathroom door, analyzed: "So Liu Dai took advantage of Yang Xin's entry into the bathroom to turn on the remote control. After confirming that Yang Xin was dead, he turned off the device, and then stuffed the body into a woven bag and threw the body away."

Wan Yi agreed: "There is a possibility."

Nie Fanxin raised doubts: "Liu is a liberal arts student and a professional chef graduate."

Wan Yi affirmed her thinking: "Modifying circuits does require a certain physical foundation."

"What are you thinking about so much? Liu Dai will be here soon, let him explain himself." Chen Anyou received a message from Xiao Liang, and the other party rushed over with Liu Dai.

"There are also woven bags of the same style." Lao Yang found four or five woven bags from the bottom of the bed in the bedroom.

Although there is no direct evidence, all indirect evidence points to Liu Dai.

Lao Yang received another call from the auxiliary police and told him about his new discovery: "Captain Chu, on February 2, at 16:8 p.m., the surveillance at the foot of Wangling Mountain recorded the front of Liu Dai, looking flustered."

Liu Dai wanted to sell the house, so he had the motive for committing the crime; the time of committing the crime coincided with the location of the crime.Even if there is no doubt in criminal proceedings, the circuit device can be learned, and it cannot be used as a real point of doubt.

At this moment, Xiao Liang dragged Liu Dai by the shoulders and pushed into the living room: "Captain Chu."

Without waiting for anyone to ask questions, Liu Dai plopped on the ground and knelt on the ground. He knew Nie Fanxin, tugged on Nie Fanxin's sleeve and howled, "I didn't kill him, trust me."

"Who was the one who pretended to know nothing yesterday? You lied under the noses of the police, my friend, you are full of guts." Chen Anyou pulled him into the middle.

Liu Dai staggered and fell to the ground again: "Listen to my explanation, I found her lying on the ground when I woke up."

Thinking of the scene at that time, Chu Wanning couldn't help but speak harshly: "And then?"

Liu Dai huddled his feet together: "I was too scared, so I put it in a woven bag and took a taxi up the mountain..."

Chen Anyou scolded angrily: "She is your own mother, if she is not dead, can she still be rescued?"

Liu Dai trembled violently: "Dead, his body is black, his eyes are wide open, how can he still be alive?"

Chen Anyou was categorical: "I don't think I can believe it, he just wanted to escape the crime of murder."

"I think it's believable." The two policemen outside the door didn't stop them. Pei Rong, who was wearing high heels, was wearing footwear indiscriminately. Perhaps it was restrained by the footwear. Her walking figure was slightly unstable, and she waved to Nie Fanxin with a smile. .
