Autumn rain famous products, second-hand luggage, jewelry, luxury goods recycling.

Yan Yu got out of the police car, slowly folded his arms, and looked at the signboard in front of him.

Ma Xiang stepped forward: "Brother Yan, the policeman is over there, we ...... just now"

Yan Yu waved his hand, and Ma Xiang stopped.

"Inform the detective teams that there is no need to touch the second-hand market," he said slowly, "and the target has been found on his back." ”

Several policemen blocked the door of the store, and the shopkeeper with a bewildered face was excitedly talking to the criminal police, and the technical detective used the evidence bag under the conspicuous black and yellow backpack, and was preliminarily extracting fingerprints for comparison.

On the sidewalk outside the store, the policeman who took the notes stood, and Jiang stopped sitting in the bench, leaning comfortably on the back of the chair, tilting his head slightly, his slender legs slightly apart. This posture was stretched like sitting on the leather sofa at home, and even when Yan Yu walked over, he didn't show any signs of getting up.

"My friend wanted to sell her spare bag, so I walked with her and saw the backpack on the counter. I think it has something to do with the case of the previous two days......"

"Just now the shopkeeper said that you turned your bag inside out before calling the police, what's going on?"

"I just want to see what's in my bag." Jiang paused and said, "In the bottom corner of the small pocket on the front of your shoulders, there are a few small pieces of tin foil, which look like they are used for chocolate, you can let the technician take a look." ”

The police have seen too many people who have come up with ideas in the process of handling cases, and they don't take it seriously, and when they heard the words, they only made a few sounds, and they were suddenly patted on the shoulder: "Yo, Yan Team!" ”

Yan Yu waved his hand, "Leave it to me." ”

The policeman said "hey", handed him the notebook, and went to the side to help.

However, Yan Yu took the record, but he didn't mean to read it at all, he only stood in front of Jiang Zhu with his arms crossed, staring at him without saying a word.

Jiang Zhu greeted politely: "Hello, Officer Yan." ”

"The police haven't approved the reward yet, and you have suffered a bit of a loss by giving clues so early."

"What are you talking about," Jiang Zhu laughed: "I just accompanied Yang Mei out on errands, and I just saw this bag occasionally." After all, I'm an eyewitness, and it's my duty to provide clues to the police, isn't it? ”

The two of them stood and sat together, the atmosphere was very calm, but there seemed to be something strange and indescribable brewing in the air.

"You did it on purpose."

Jiang stopped and said, "Oh? ”

"You want to know why I'm going back to the site to see what I found on the road. There are two second-hand luxury goods recycling points centered on the Sleepless Palace KTV, which are closer to each other, but you have found this one. Yan Yu narrowed his eyes slightly and looked at him unabashedly: "You have an unusual level of attention and participation in this case, why?" ”

"You're thinking too much, officer." Jiang Zhu smiled and said, "This is just a relatively high bid." ”

A technical detective hurriedly stepped forward: "The results are out, Deputy Yan!" After a preliminary comparison of the fingerprints on the backpack and the deceased, we brought the evidence back to the city bureau for detailed analysis. In addition, according to the owner's confession, this bag was sold at a low price by a man at about 8 o'clock in the morning on the 3rd, the man was holding a Toyota car key, and we are contacting the traffic police brigade to obtain the surveillance license plate record of this road section......"

"Has the in-store surveillance been adjusted?"

The technical detective affirmed: "It's being adjusted, and I'll come out right away." ”

Yan Yu was silent.

"There's only one thing, Deputy Yan." Technical detective is a little difficult: "Eight o'clock in the morning is the peak traffic period, there are a lot of vehicles passing on this road, and it is very difficult to lock. ”

When Yan Yu listened to the report, his eyes kept staring at Jiang Zhu from high to low, and he didn't even move away when he opened his mouth to talk to someone.

Jiang stopped folding his hands in front of him and looked back quietly.

"—Ma Xiang," Yan Yu raised his voice.

Ma Xiang ran forward with a smoke: "Hey! ”

"I asked you to call up the surveillance at the intersection where the crime occurred, and after screening, is there a Toyota among the seven cars?"

Ma Xiang was stunned for a moment, and immediately: "Yes!" There is one! Immediately after that, the license plate number was reported.

Yan Yu's eyes didn't move, and his face was slightly offset to the technical detective: "Compare it with the monitoring of this road, if you get on this car, immediately go to the traffic management bureau to check the owner." ”

The detective was amnesty: "Yes! ”

The technical detective and Ma Xiang both hurriedly went, and only Jiang Zhu and Yan Yu were left on the bench.

More than ten meters away, Yang Mei took the time to walk this way in the interval between being interrogated by the police, but then she was stopped, leaving only a worried gaze that she didn't have time to hide.

Yan Yu said leisurely: "Your girlfriend seems to be very afraid of you being alone, are you worried that I will eat you?" ”

Jiang Zhu replied very cleverly: "If Officer Yan also has a half-crippled girlfriend who has nothing to do, I guess I can understand her feelings." ”

"You don't have anything to look at?" Yan Yu immediately asked: "Can a person who has no long objects find clues one step ahead of the police?" ”

Jiang Zhu said helplessly: "There is no way to do it by coincidence." ”

Jiang Zhu's attitude and response to the police are not only cooperative, but can even be described as soft. But Yan Yu's well-defined face did not show anything, and there was even a faint solemnity.

The two looked at each other but didn't make a sound, and were silent for more than ten seconds, and suddenly Yan Yu opened his mouth:

"Feng Yuguang is a graduate student from a prestigious university, who came to Jianning for an internship and is preparing for the doctoral examination, and the cause of death is the combined effect of various addictive drugs such as scopolamine and methylenedioxymethylbenzene|propylamine."

Jiang Zhu sighed: "I see, no wonder he has to run to the refrigerator." ”

"So you have any inspiration, Mr. Lu?"

"Huh?" Jiang stopped back with just the right look of surprise: "No, look at what you asked......

"So what do you say?"

“……”

Yan Yu said coldly: "I only said addictive drugs, but you immediately heard the meaning of hallucination. Most people don't know what scopolamine and MDMA are when they hear about it, or do you study pharmaceutical chemistry in college? ”

Jiang Zhu's calm and relaxed attitude finally changed a little.

— but that's less than a hundredth of a second. Then he showed a more subtle, somewhat similar to crying and laughing, and said, "Hmm...... Officer Yan, although I didn't go to college. However, people who often take motion sickness medicine know scopolamine, you must know that there is not only scopolamine in this world. ”

Yan Yu opened his mouth, as if he wanted to say something, but at this time, Jiang Zhu interrupted him.

"I don't know where I've offended you that makes you so suspicious. But since you're so close to the murderer, there's no need to hold on to me, a law-abiding citizen, right? ”

Yan Yu: "Did you say last time that you wanted to break up with your girlfriend and go back to the county?" ”

Jiang stop: "......"

Yan Yu said, "You wait. ”

Yan Yu turned around and left, and the detective was coming out of the second-hand store, beckoning to him from a distance: "Found Deputy Yan!" The white Toyota Camry, passing by the scene on the day of the 502 incident, left this section of the road at half past eight in the morning the next day, this is in-store monitoring! ”

Jiang Zhu's inexplicable gaze stared at Yan Yu, who could clearly feel his gaze, but ignored it, and took the color print from the picture detective to take a look.

In the surveillance camera of the store, a man of medium height, slightly fat, about 40 years old, carrying Fendi on his shoulders, is standing in front of the counter, discussing something with the owner of the second-hand store.

"Has the news from the Traffic Management Bureau come back, what is the name of this grandson?"

"Uh, can't find ......"

Yan Yu frowned.

The detective cautiously said, "The one he drove is ...... Set of brand cars. ”

The truth is close at hand, but the clue snaps and breaks.

Yan Yu didn't squeak, the muscles of his cheeks tightened, and the lines of his shoulders and backs were also stretched under the white shirt, like a tightened bowstring.

No one spoke for a long time, until footsteps came from not far away, standing behind Yan Yu. Immediately, Jiang Zhu's very kind voice sounded: "Officer Yan, if there is nothing else, can I go?" ”

Yan Yu suddenly stretched out his hand, hooked Jiang Zhu's shoulder in the surprised gaze of Tu Zhen, and took him directly into his arms without saying anything, and shook the color seal in his hand: "Do you know?" ”

In those few seconds, Yan Yu's scorching gaze could even feel the heat on his skin, Jiang Zhu's eyes drooped, and he only stayed on the man's image for a short moment, and then a look of "spare me" appeared.

"How can I recognize this, don't the police on TV always check the vehicles with criminal records first, and then check the people with criminal records? I'm not even an eyewitness. ”

Yan Yu finally let go of him, patted him on the shoulder vigorously, and said with a smile: "Don't go back." ”

Jiang Zhu: "......?" ”

"You are considered a person involved in the case, and you are restricted from going out before the case is closed, and you must stay in Jianning."

Jiang Zhu's face stiffened slightly, but Yan Yu turned around in a dashing manner, like a general who had beautifully pulled back a city, and patted the color printing paper on his hand while striding towards the police car: "Call it a day, go back to the city bureau!" The technical investigator brought the evidence back to extract the target's fingerprints, and investigated the vehicles and ex-convicts in the city, Ma Xiang! Drive! ”

The police car came and whizzed away, and Yan Yu disappeared like a wind sweeping leaves, wrapped in all clues.

Jiang stopped standing in place, his face sinking like water.

"Brother Jiang, how is it?" Yang Mei walked forward quickly, and her expression couldn't hide her panic: "Does that person surnamed Yan have ......?"

"He's suspicious."

Yang Mei's heart jumped for a moment: "Then what should I do?!" ”

Jiang Zhu's mind slowly appeared that the man on the surveillance image just now raised his hand to straighten the placket of his clothes that had been torn crooked because he was forcibly taken by Yan Yu just now, and said expressionlessly: "Cold salad." ”

·

"Brother Yan," Ma Xiang couldn't help but ask as he drove, "Do you think that kid named Jiang is suspicious?" ”

Yan Yu leaned his back in the seat to the end, and his two sturdy long legs stretched out under the co-pilot, as if he was closing his eyes and taking a nap: "It's not like that." ”

"How?"

"If you are really suspicious, you won't deliberately pass us clues, but this person is a bit weird."

Ma Xiang didn't know why, and Yan Yu didn't explain: "-You have also dealt with him twice, how do you feel?" ”

"......" Ma Xiang was puzzled: "Brother Yan, it's not that you don't know me, I don't have feelings for men......"

Yan Yu's eyes opened.

Ma Xiang smiled and shrank his head and begged for mercy: "Isn't this really a feeling!" I didn't take his record on the night of the crime, I just took a picture. But this person, quite cooperative, is indeed more positive, but other than that, he doesn't have much of a sense of existence. Anyway, if he goes out on the street with his girlfriend, I must pay attention to his girlfriend first, and I don't pay much attention to what he's doing. ”

"Don't you think there's a sense of incongruity in him?"

"I don't feel it," Ma Xiang said inexplicably, "where is it not coordinated?" I think he looks quite coordinated, but he's a little weaker. ”

Yan Yu pondered for a long time, and suddenly said, "No, it's too natural. ”

"Huh?"

"With a county background, a migrant background, and being sick in bed for so long, I didn't have any sense of cringe caused by ignorance of the outside world, and my posture was so stretched in front of a group of armed criminal police." Yan Yu pondered for a long time and muttered, "Why? ……”

When he was about to arrive at the city bureau, Ma Xiang turned right into the door with the lights on, and said with a smile: "I can't figure it out, don't think about it, Brother Yan, I see that you are stuck in the case and drilled the tip of the horns, and if you think about it, I suspect that you are not interested in the boss, but her boyfriend, hahaha——"

Yan Yu said contemptuously: "What do you say, Lao Tzu will be interested in men?" ”

Having said that, when Yan Yu lay back in his chair, he subconsciously remembered the scene when Jiang stopped sitting in front of him just now, raised his head, folded his hands softly and gracefully on his thighs, and smiled slightly at the corners of his lips.

"It's just a coincidence."

"There are a few small pieces of tin foil stuck in the bottom corner of the bag, like chocolate."

…… also add a qualifier chocolate, the girls chirp, it can be seen that they usually eat snacks all day long.

Yan Yu kept thinking in his heart, so he simply didn't pretend to sleep, got up and reached the evidence box from the back seat, put on gloves, and took out the man's shoulders from the evidence bag. There was indeed a small zipper bag at the front of the backpack, but this zipper head fell off, Yan Yu put his hand in and flipped through it, and really found a few small pieces of tin foil each the size of half a fingernail from the crack.

He looked at it suspiciously for a moment, feeling that something was wrong.

These pieces of tin foil are significantly harder than the ones usually used to wrap candy and chocolate, but they seem to be ......

Aluminum foil medicine board!

The inspiration that had loomed from the morning to the present finally joined in a thread, and the speculation surfaced and revealed the clues.

Yan Yu grabbed his mobile phone and hurriedly dialed it: "Hey, Ergou?" I'm Lao Yan! ”

"My name is ......"

"Listen to me, is there a medicine that students take before the exam, which can make people quickly increase their IQ and pass the exam 100%, and then it is similar to the composition of motion sickness pills and ecstasy, so that it misleads the autopsy report and makes the forensic doctor think that the victim died of a drug overdose?"

Gou Li said gloomily: "Do you think our forensic doctors are so stupid, you might as well call me Ergou." ”

Yan Yu: "......"

"But the kind of medicine you mentioned is really there, it is a prescription drug that has only recently come from abroad, commonly known as 'brain viagra'. The main ingredient is benzenylpropylamine, which is less methyl than ice, and is a central nervous system stimulant, which can accelerate brain reaction time and improve executive ability. However, an overdose can cause hallucinogenic effects, which are quite similar to the symptoms of the deceased. Gou Li asked, "What's the matter, do you suspect that the real cause of death was an overdose of amphetamine?" Unlikely, we did detect scopolamine and MDMA, which is 1600 times the normal dose. ”

"Then what if," Yan Yu said slowly, "what if the deceased didn't know what he was eating, and he just wanted to buy amphetamine to review the exam, but he didn't expect the seller to seduce him into taking drugs?" ”

Gou Li was stunned.

"- What was the name of the 'Brain Viagra' you just said?"

"Adderall," Gou Li stammered a little, "Chinese called...... Call that, Adderma! ”

·

"Students from wealthy families, good schools, and school students who have a record of drug overdose; The city counts two years forward, and the province counts four years forward! ”

"The ex-convicts who have left a criminal record for illegally purchasing foreign prescription drugs, and those who have had the opportunity to contact patients with ADHD and obtain a large number of drugs Adera, the list is all pulled out and cross-compared with the drug use records, and reviewed one by one!"

Yan Yu gave an order, and the large office of the criminal investigation detachment suddenly became a sea of case files.

Solving a case in reality is different from a mystery novel, it is not enough to rely on clues on the scene, and more time needs to be spent on a lot of visits and tracking. The 48 hours after the homicide is the golden detection period, and if no key breakthrough is found in two days and two nights, the investigation process will be very difficult.

The hands of the big clock on the white wall rotated in circles, the sky gradually darkened, and the golden period passed in a flash, and the heat of instant noodles mixed with the white mist of cigarettes steamed in the light.

When the first ray of light broke, the office door was pushed open, and Qin Chuan hurriedly entered with a case file, "Bang!" A slap was slapped on Yan Yu's face.

Yan Yu maintained a posture of sitting upright behind a pile of case files, and woke up in shock, and hurriedly caught the case files: "What? How? Got it? ”

"Hu Weisheng," Qin Chuan snatched back the case file, opened it with a bang, and pointed to the suspect's portrait: "Smuggled and counterfeited prescription drugs such as Adderal, Ritalin and Moda|Feni, made a profit of more than 50,000 yuan, and was released from prison half a year ago." Last month, the anti-narcotics detachment caught a 19-year-old boy who was addicted to drugs and came to the street to commit a crime, and he was the son of this guy's landlord! ”

Yan Yu pulled out the surveillance image of yesterday's famous product in Qiuyu, and compared it with the case file, "It's almost." What about Ma Xiang? Go to the Traffic Management Bureau to check the registered vehicle under Hu Weisheng's name! ”

Ma Xiang's strong network of friends from all over the world has once again contributed to his strength. At half past four in the morning, the traffic management bureau sent back news that it was determined that Hu Weisheng had a second-hand white Toyota Camry under his name, and the model model was completely consistent with the Toyota car that appeared at the scene of the crime.

"That's the grandson." Yan Yu knocked on the table with his knuckles, and casually pointed to a few fierce young men in the criminal investigation group: "Prepare to implement control and get Hu Weisheng back for me!" ”

The overtime work for two consecutive days and nights made everyone hold their breath, especially the backbone of the detachment such as Yan Yu and Qin Chuan, who didn't go home for two nights and slept for two nights. Therefore, as soon as the order to arrest the people was given, the entire detachment rushed out in a boiling spirit, and the field service group was half empty in an instant.

Yan Yu patted Qin Chuan's shoulder: "It's hard work, the anti-drug brother is also ......" Before he finished speaking, he choked, and saw Qin Chuan, who was still awake ten seconds ago, with his face against the corner of the wall, his glasses crooked on the bridge of his nose, and he was snoring comfortably in a very pure and unpretentious posture.

"......" Yan Yu walked back to the office lightly.

It was five o'clock in the morning, and the dark gray sky was faintly bright. Yan Yu simply didn't sleep anymore, and took Hu Weisheng's case file to study it word by word.

Since the age of sixteen, he has been repeatedly arrested for petty theft, and when he became an adult, he stole wallets, mobile phones, and electric cars and entered the palace several times. A few years ago, in Gongzhou, he was sentenced to three years for attempted rape.

Yan Yu rubbed his chin that was sticking out of his beard and sighed softly.

Hu Weisheng is a "street thief", and the target is usually personal belongings, and there is no record of burglary. From this point of view, he will not be very bold, and the nature of the crime is quite far from rape, and it seems very suspicious to suddenly "cross the line".

Yan Yu stared at the word Gongzhou on the case file, and suddenly a place moved in his heart.

"Brother Yan," suddenly Ma Xiang poked his head in: "The top students of internal chemistry are still locked up in the bureau, it's been almost twenty-four hours, can you let it go?" ”

Yan Yu raised his head: "What, it's still closed?" ”

"The monitoring of the laboratory on the technical detective side can't be restored, and no one will let him go for a while. No, I slept in the interrogation room all night last night, and now I actually have a cold, and I'm coughing there with a cardboard box. ”

"Hurry up and let go, don't go to the Wei Bureau to complain about us. - By the way, tell him that he is not allowed to leave Jianning, keep in touch with the police at all times, and pay attention to discipline. ”

Ma Xiangyao made an OK gesture: "No problem, Xueba said that he would not complain, just send him back to the laboratory quickly." ”

Yan Yu waved his hand, motioned for Ma Xiang to go out, and closed his office door.

There was a soft click, and the office at five o'clock in the morning was quiet, only the switch in the lower right corner of the computer screen flashed quietly with a yellow star.

Yan Yu's middle finger knocked on the table absentmindedly, wandering for a long time, and the strange feeling in his heart always lingered.

It's so smooth, he thought.

From tracing the license plate, to finding the deceased's backpack, to launching the current suspect with a very weak logical chain, although two days and three nights have passed, in fact, the detection process is still too smooth, and it seems that some details are difficult to say.

A drug dealer has been selling prescription drugs and hallucinogens for a long time, why did he eat people to death this time?

How could it be that nothing had happened before?

Is there really something wrong with the recipe this time, or is it that the previous "accidents" have been suppressed for various reasons, and only this time the victim happened to die in front of his eyes, so that some facts can no longer be covered up?

Yan Yu turned on the computer, logged on to the public security intranet, and after thinking for a while, he entered a string of database passwords, opened the electronic backup of the files of previous years, and then typed the file number left by Hu Weisheng in Gongzhou.

The screen changed suddenly, and a case of attempted rape that had already been settled slowly unfolded in the dim early summer morning, presenting in front of Yan Yu.

Liu Xue, 18 years old, is a student of a well-known high school in Gongzhou.

At noon before the arrival of the second model, the senior high school girl sneaked out of the school dormitory during the lunch break and disappeared for an afternoon. The next day, the parents reported that the disappearance of less than 24 hours attracted the attention of the police station, and it was immediately pushed to the district office.

The sub-bureau detachment took over the case.

The next night, the criminal police found Liu Xue unconscious in a black clinic according to a large number of searches.

Later, according to the investigation, the suspect Hu Weisheng met Liu Xue, who was sneaking out because of too much pressure on the exam, and his heart suddenly rose, and he lured her into the car and took rape drugs. Unexpectedly, Liu Xue was allergic to drugs, and immediately had dizziness, vomiting, and coma, Hu Weisheng was scared, worried that someone would kill him and implicate him, so he hurriedly threw her into the black clinic.

The case was characterized as an attempted rape, Liu Xue was discharged from the hospital after treatment, and Hu Weisheng was sentenced to three years.

Yan Yu looked at the file for a long time and didn't react - just sentenced like this?

What are the victim's allergens? What kind of medicine is ordered? If a man drugs a woman, it must be rape? If it was really intended to be raped, why did the victim just fall into a coma, and the rapist was so frightened that he sent her to the clinic?

In less than half a month from the filing of the case to the transfer of the case, such an obviously well-informed case was closed in such a hurry, and no one in the criminal police handling the case raised suspicions?

Yan Yu has handled criminal cases for more than ten years, and has an extremely keen sense of suspicion in various details, this file made his suspicions bigger and bigger, and finally couldn't help but turn to the end and look at the list of handlers and the signatures of the main leaders - his gaze froze.

The host leader of the year was named Jiang Zhu.

A huge black shadow emerged from the abyss, and at that moment, the figure that had repeatedly appeared in the dream finally quietly looked back at Yan Yu.

Only this time he didn't focus on the phone, and he didn't skimp on his slightest attention in his busy schedule. The light of day came in through the window, outlining his handsome and elegant outline, and his lips, which were naturally very thin and tight, so that they appeared somewhat indifferent.

He lowered his gaze from the void and cast a quiet, clear gaze.

“……”

Yan Yu's throat seemed to be grabbed by an invisible hand, his breathing was held in his chest, and even his hands trembled a little. By the time he realized what he was doing, he had already entered the intranet database and searched out the list of the main leaders of the Gongzhou Municipal Public Security Department that year.

-- Jiang Zhu, the second captain of the Gongzhou Anti-Narcotics Corps, has a conspicuous black frame on his name, and his death was confirmed three years ago.

Yan Yu's mind boomed.

The man who had been sitting on a bench on the side of the street and smiling at him only yesterday was wearing a dark blue uniform and carrying three four-pointed stars on his shoulders, his eyebrows clear and stark, cold on the computer screen.
