"Give it up," he said with that smile, "you can't catch me."
Cai Lin ignored him. After a while, the phone rang suddenly, and the ringtone was particularly clear in the small space. He picked it up immediately: "How about Director Wang?!"
Everyone's breathing stopped for a moment, the air was suddenly pressurized, and it was so quiet that a needle could be heard falling to the ground—
"The trace DNA sample extracted from the gap between the victim's front teeth was compared with the DNA sample of the suspect." Director Wang's voice paused on the phone before he said solemnly: "The sequencing results show that the two do not match."
"—The murderer who killed Gao Ling was not Li Hongxi."
·
Director Wang hung up the phone, raised his head, and looked at Bu Chonghua sitting on the bench.
The physical and chemical analysis room does not need to be on night shift, the corridor is empty, and the lights reflect a blurry blue light on the white walls and floor tiles. Wang Jiuling sighed, and reached out to pat Bu Chonghua's shoulder. Before he could say anything, Bu Chonghua suddenly blocked his arm and said hoarsely, "Go run the DNA database."
Wang Jiuling said with a rare good temper: "Yes, I will send someone to run early tomorrow morning. But you must be mentally prepared. Running DNA is different from running a fingerprint database. The STR loci we can support now are only 24, often There are not even 11 chromosomal loci, and the total amount of data is greatly increasing, which makes the possibility of random matching of unrelated individuals much greater than before; and we do not support kinship comparison for the time being. If you want to catch the murderer from the database, then This person must have committed a crime before, and after committing a crime, he must leave a sufficient amount of DNA samples, and all the points must be exactly matched to get the result, so you…”
Bu Chonghua interrupted abruptly: "Let's run now, don't miss a minute, I'll call the city bureau and let them go through the formalities overnight."
The two looked at each other for a long time, and Director Wang hesitated.
Bu Chonghua's eyes were extremely hard and calm, and he pointed in the direction of the mortuary: "The little girl lying on the dissection table has been ignored since birth, bullied, abused, and maybe even raped. She struggled again and again to want to go to school, planned again and again to work and make money, ran to the big city with that poor luggage, and rented in a shabby urban village shantytown, but was finally used by the murderer in the flood discharge tunnel under the heavy rain. The stone shattered the occipital bone, choked to death with his neck and neck covering his mouth and nose, and was given the notoriety of prostitution and extortion after his death."
"The murderer was 180 to 184 in height and weighed at least 80 kilograms, while Gao Ling was only 160, so the strength ratio was huge. The last thing she could do before her death was to bite her with her teeth so hard that we extracted the material from the gap between the teeth. That little bit of DNA." Bu Chonghua looked directly at Director Wang, and his voice was low: "Even if the possibility is low, even if I hunt down the ends of the earth, I will catch the person who killed her."
"All her resistances in her short seventeen years of life have failed, and I will never let her last resistance fail again."
The sound was so calm that there was almost no ups and downs, but it echoed for a long time in the empty corridor in the middle of the night.
In the shadow on the other side of the corner, Wu Yu leaned his back against the cold wall, lit a cigarette with a click, and let out a long, light puff of smoke.
If you look from the direction of the stairs, the night sky outside the window is quiet, the lights of thousands of homes in the distance, and the surging waves of the Sili River are rushing to the sea; Standing in the darkness on the other side, half of his face was facing the faint light in the distance, shrouded in a curling cigarette, and the 90-degree angle seemed to be separated into two worlds by light and shadow.
The clock on the wall was ticking, and the lights in the half-floor office in the technical department were on and off, on and off.
Suddenly a burst of hurried footsteps came from the stairs: "Bu Chonghua!"
Wang Jiuling, who went back and forth, hurried downstairs, unable to hide his excitement from the exhaustion on his face, strode forward and flashed a few pieces of paper in front of him, before he even had time to snort in a show, the first thing to do was:
"You boy is lucky, you don't have to go to the ends of the earth!"
Bu Chonghua grabbed the comparison results, and the prison photo of a man with a small brow and a flat head came into view—
"Hey, look at it: Gao Baokang, 24 years old, has been imprisoned for four years for rape, and lives in the Pinghai Development New Area of Jinhai City after his release. The sequencing result exactly matches the murderer's DNA extracted from Gao Ling's mouth! ?"
Bu Chonghua slapped the paper into Director Wang's arms: "Catch someone!"
oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo-
Four police cars flashed red and blue lights, and their sirens pierced the night sky. They turned their heads and rushed out of the gate of the Nancheng Branch, merging into the late-night traffic in the main city.
"Gao Baokang, graduated from high school, his parents both opened mahjong stalls in the county below, and they doted on this only son. I don’t know how many times I went to the police station. I finally couldn’t finish high school, so I hung out at home. My parents sent him to relatives’ house in Jinhai to ‘find a job’. The result was gambling and pyramid selling. Nine-year-old bears full criminal responsibility, yes! Go to prison without stopping, look at their efficiency!"
"Who is his relative?" Bu Chonghua asked while driving.
"My aunt, married a husband and opened a small company in the development zone. From the case file, he is a textbook-style helper demon, who digs his heart and lungs for his younger brother and nephew. Gao Baokang is imprisoned. Soon my husband took the child and divorced her." The voice of Cai Lin flipping through the transcripts came from another car on the Bluetooth side, and suddenly he said, "Wait—well, we got married again last year! Okay, Steamed buns and dogs will last forever, the ancients will never deceive me!"
"?" Wu Yu, who was sitting on the co-pilot bowing his head and eating buns, made a move.
Bu Chonghua looked ahead, took out the thermos cup from the car door, and threw it into his arms: "The house he lives in now is his aunt's?"
"Yes, I have confirmed with the Pinghai District Police Station. This person has not shown much improvement after he was released from prison. He is still a master of stealing chickens and dogs. The day before the 502 case, he was brought back once because he threw a wine bottle downstairs." On the other side, Cai Lin slammed away the case file and said, "Don't worry, the boss, he has already told the police station to send someone to guard it, go in and arrest!"
"..." Wu Yu held the thermos cup, and after hesitating for a long time, he finally opened the lid, and the hot smell of "imported milk powder" came out.
Gao Baokang lives in a semi-open old community. The gate is close to the main road, and there are clear roars from vehicles going back and forth. The siren was turned off after getting off the expressway. The blue-white police car whizzed into the community and stopped downstairs in unison. Bu Zhonghua neatly got out of the car and randomly ordered a few heads: "You guys surround the unit building. , Zhang Xiaoy guards the gate of the community so that no one can enter or leave casually, and the rest will follow me. Have you brought the door breaker?"
Zhang Xiaoyu had a rare wink, and immediately pulled out the tool from the trunk: "I brought it!"
Bu Chonghua glanced at the corner of his eyes and saw that there was no one around, he took the door breaker from Zhang Xiaoyue, leaned slightly closer, and said in a low voice between his teeth:
"If you put irrelevant personnel on the scene of the operation this time..."
Zhang Xiao Yue shrugged: "Yes... Yes! Yes!"
Zhang Xiaoy slipped away like a hare with prolapsed anus. Bu Chonghua turned around and bumped into Wu Yu, who was walking around from the other side of the police car. He was rubbing the hand that had just finished eating the buns on the police uniform's pants:
"Didn't you scold me last time?"
"… "
The surrounding police quickly dispersed, and the action scene took their place, only the two of them stood under the shade of the tree and looked at each other.
Bu Chonghua asked with a sullen face, "Have you finished drinking the milk?"
Wu Yu's movements froze, and Bu Chonghua passed by with his head held high.
The old-fashioned residential corridors are low and narrow, and are full of debris from various households. Cai Lin rushed to the third floor first, Mao Yao listened to the movement, and made a no gesture backward, meaning that he couldn't tell if anyone was home.
This is also normal. After all, it is already late at night. Even if the murderer is at home, he is probably sleeping. Several criminal police officers surrounded the entrance of the upper and lower floors. Bu Chonghua handed the door-breaker to Cai Lin, and Wu Yu whispered in his ear, "Aren't you kicking yourself?"
Bu Chonghua held the gun in both hands, and said softly with the same volume: "Have you watched too many TV series, can you try kicking this security door?"
Cai Lin skillfully took out the lock pick, opened the outer iron gate with a few strokes, then stuck the door breaker on the wooden door frame, filled the pump, motioned other colleagues to step back, and pressed the valve. The next moment, the wooden door "Bang!" flew in response, hit the wall heavily and bounced back, and was kicked open by Bu Chonghua: "Don't move! Police!"
Snapped! The lights in the living room were lit, and well-trained criminal policemen rushed into each room like lightning. The bedroom, bathroom, and balcony doors were kicked open one by one. Cai Lin jumped onto the bed and shot against the quilt: "Don't move!"
"do not move!"
"police!"
With a whimper, Cai Lin lifted the quilt, and it was empty: "No one is on the bed!"
"No one on the balcony!"
"Nobody in the bathroom!"
The lights inside and outside the apartment were bright, and the windows, balconies, and door latches were intact, but there was no shadow of the suspect. Bu Chonghua used the muzzle of a gun to open the gap in the wardrobe door and glanced in, turned around and shook his head, and said solemnly, "Run away."
Cai Lin couldn't help but say one word: "Fuck!"
This is an old-fashioned two-bedroom. There is a wooden square table in the living room with old newspapers pressed with glass, two chairs next to it, a chest of drawers, a telephone, and an old light green single-door refrigerator with peeling paint. There were bags of potato chips, instant noodles and empty wine bottles piled up in the trash can in the kitchen. Several broken vegetable baskets were piled up in the corner, and there was an unpleasant smell from rotting vegetable leaves.
"Ports, wharves, airports, stations, several major traffic roads and highway exits, all safety monitoring outlets must be in place, and at the same time, a unified investigation notice is issued to the traffic police and security units... Gao Baokang has never been to more than Jinhai except for pyramid selling outlets in his life. In a faraway place, even if he runs away, he will not be able to run far, immediately go to check on his aunt’s family, and conduct a strict screening of the suspect’s social relations!…”
Bu Chonghua's calm and stern phone call came from the outside. In the bedroom, Cai Lin grinned, lying on the ground and digging things out from under the bed. He took out countless pieces of dry toilet paper, moldy fruit peels, unpleasant snack bags, and jingle bells. When there were several empty beer cans... Then I used a broom to pull out a few heavy large Coke bottles, just glanced at it, and almost spit it out with an "Ow".
Wu Yu was looking through the drawer while wearing gloves, when he heard this, he immediately took a half step back: "Maggot?"
"Cough! Cough! Cough!" Cai Lin retched and rolled his eyes, forcibly holding Wu Yu's shoulder with one hand to prevent him from running, and pointing back with the other hand - Wu Yu glanced at the large Coke bottles on the ground. It was filled with turbid yellow liquid, and under the dim bedside lamp, a blurred light flickered.
"... Didn't you say last time that you were the only one afraid of maggots in your life?"
Cai Lin said angrily: "I'm not afraid doesn't mean I'm not disgusting!"
Wu Yu said, "Don't be disgusting, this is water for shredded tobacco."
"..." Cai Lin's doubtful eyes glanced at the large bottles of mysterious yellow liquid on the ground, and then at Wu Yu. The latter's calm face remained unchanged for eight hundred years, and he returned with a calm and encouraging gaze.
"How did you know?" Cai Lin finally asked hesitantly.
Wu Yu said, "You know it if you open it and smell it?"
"Ow—" Cai Lin rolled his eyes and covered his mouth, and rushed into the bathroom in a rage.
Wu Yu laughed dumbly, and walked over to separate the pile of various garbage on the ground with his toes. Seeing that there was no special clue, he lifted the quilt that was in a ball and threw it on the ground, picked up the sheet and shook it twice.
pat!
The sheets brought a booklet out of the corner of the bed frame, dropped it on the ground, and opened it in an uproar, revealing the bolded chapter title—"Listen to God's Voice, Watch God Appear."
Wu Yu: "..."
Wu Yu leaned over and picked up the open booklet. His tentacles felt that the paper was thin and rough. The printing quality was obviously different from the professional books he was familiar with. The paper seemed to be paler, like an A4 straight out of a printer. Paper. The transparency of the page is quite high. He moved the bedside lamp closer and saw a few words printed under the heading of the chapter in bold:
"…the sacrifice is the will of God, and it is right for a Christian to offer sacrifices to God that are pleasing to him…"
"You will no longer have marriage in your mind. Those who believe in 'Almighty God' and the female Christ will no longer be male and female. They can sleep in the same bed and communicate with each other in spirit..."
What the hell is Almighty God
When Wu Yu opened the cover, he saw lightning and a yellow cross printed on a dark blue background. The title was "Have You Heard the Voice of God?" 》
"Did you hear my voice?" Bu Chonghua said coldly.
Wu Yu didn't turn his head back. Just as he was about to tell him to stop arguing, Bu Chonghua involuntarily reached out and took the book from behind him. He casually turned two pages, and his face changed slightly: "Where did you find it?"
Wu Yu pointed to the corner of the bed frame, "What is this?"
Bu Chonghua rarely paid attention to the answer. He carefully rubbed the printing paper used for the booklet, and then looked at the light to see the degree of read-through. High, low dpi, it should come from Kuaiyin shop. - Haven't you heard of that case?"
Wu Yu spread out his hands.
"In 2014, Zhaoyuan, Shandong, May 28 McDonald's intentional homicide." Bu Zhonghua snapped shut the brochure: "Sure enough, the people who killed Nian Xiaoping and Gao Ling are inseparable from the cult organization. When this case is solved, I will give you a week off at home to review all the hot news in the past 13 years, but now, you should have made a contribution."
Wu Yu: "?"
Bu Chonghua raised his eyebrows at him: "The premise is... the guesses of the academic leaders are correct."
Bu Chonghua is worthy of being a police officer of the investigation department back then. At such a close distance, when he raised his eyebrows and looked at someone, those usually sharp and cold eyes flashed with a playful light, which can really give people A thumping feeling.
Wu Yu raised his head and stepped back half a step, looked him up and down distrustfully, but was slapped on the shoulder by Bu Chonghua with a book: "Wait and don't move, the leader will make a magic trick for you."
Bu Chonghua walked out of the bedroom, and after a while came back with the survey flashlight, and turned off the bedside lamp. The entire bedroom was plunged into darkness, with only a dim yellow light showing through the crack of the door. The two of them stood head-to-head, and Bu Chonghua casually flipped a page of the booklet and lightly turned on the LED light.
The faint blue light shone on the pages of the book, and after a while, several rows of bright yellow bright spots scattered disorderly appeared on the pages in the darkness.
"Did you see it?" Bu Chonghua asked softly, looking at Wu Yu from the corner of his eyes, his thin lips slightly hooked.
Wu Yu: "..."
The wall clock made a clear tick, and vague conversations and footsteps came from the living room, making the bedroom quieter, with only their mutual breaths lingering in the shadows.
After a while, Wu Yu hesitated: "Isn't this tracking the matrix?"
Bu Chonghua's expression suddenly froze.
"Irradiate the laser printed paper with a blue light diode, and you can see a matrix of yellow dots on the paper. This is because most laser printer manufacturers will implant a TDM before the machine leaves the factory, and each paper printed with this printer will be used. There will be yellow micro-dots on it. Then use the program to parse these yellow micro-dots, and the serial code, serial number and built-in time of the machine will come out. By querying the serial number, you can track who the buyer of this machine is - so I was in those days. Looking at Zhang Boming of the special affairs team, they all try to use domestic laser printers, or they will add a custom TDM, so that even if the document flows out, the printer can be traced back." Wu Yu paused, looked at Bu Chonghua, and asked: " Are you going to start doing magic for me?"
Bu Chonghua: "..."
Bu Chonghua put away the flashlight, turned on the bedside lamp with a snap, and said coldly, "What magic, go to work."
