At six o'clock in the evening, the setting sun set against the mountains, and the afterglow gradually faded, but the criminal investigation office building did not feel cooler because of it.

The cooling effect of the old air conditioner that had been working in the corner for nearly five years was not satisfactory, and all the field personnel who had returned to the criminal police team were sweating while sorting out the investigation results of the case.

The iced coffee bought by Yin Hao and Xiao Stool was snatched within half a minute after it was placed on the table.

Chai Lu put the iced coffee on her face, and sighed comfortably: "It's so cool, it's hot and stuffy every day, I should have applied to go out if I knew it, so I can enjoy the heat."

The little stool teased: "Forget it, I really let you go out, and later I will say that I tanned your skin."

Ci Bin said: "Xiao Lu is not that kind of person."

"That's right, it's Brother Ci who speaks fairly, so I'm not so delicate." Chai Lu took a sip of coffee and said, "However, I'm really the only one left in the police force, except for Yin Hao, all of you men They're all like black charcoal."

The little stool sneered and said, "You are a little fairer than us, but not every man is darker than you. I just met a man who is whiter than you today."

Chai Lu pretended to be angry: "Who? Which stinking man is whiter than my old lady?"

"Your little Jiu." The little stool pouted at Yin Hao, "If you don't believe me, ask Yin Hao, not only is he whiter than you, his skin is better than yours, and he is also prettier than you."

The expression on Chai Lu's face at this moment was very exciting. She didn't seem to be angry at being compared to a man in appearance, but asked Yin Hao with great interest, "Yin Hao, is it true? He's a handsome guy."

Yin Hao put down the documents in his hand, looked at Chai Lu: "It seems to be whiter than you, and looks good, too."

"That's okay? Yin Hao, I didn't expect that the pressure of competition among you handsome guys is so great. You can't deny other people's looks against your conscience." The little stool smiled meaningfully, "Anyway, you two choose a spouse. The scope does not overlap, there is no competition."

Chai Lu kicked her feet on the ground, and the chair slid directly to Yin Hao's side: "Yin Hao, go find Xiaojiu next time, and take me with you."

Yin Hao glanced at Chai Lu, then turned to look at the case materials.

The little stool said: "There will be no next time, the suspicion of Ji Shang has been completely ruled out..."

"Completely rule out? That's not necessarily the case!"

The little stool's words were interrupted by Cao Weiwei who walked into the office head-on, and Chai Lu quickly retreated to his desk like a mouse seeing a cat.

Because of Cao Weiwei's words, Yin Hao and Ci Bin, who were concentrating on sorting out the materials, raised their heads instantly.

Cao Weiwei raised the information in his hand: "All the first team entered the meeting room, and the autopsy report and the trace inspection report of the case scene have been obtained."

"The logistics has sent the information to your respective mailboxes. Let me tell you some key information." Cao Weiwei pointed to the small stool: "Last night's sudden rainfall caused the temperature to drop, and the body temperature detection data and insect egg information were affected. , In addition, no rainwater samples were found in the body of the deceased, and the time of death was finally corrected to be between 10:30 and 11:30 p.m. on July [-]. If today’s investigation work did not cover this time period, all investigations will be re-examined.”

The little stool clicked his tongue, Cibin has always been steady and tolerant, and there was still no disturbance.

Yin Hao frowned, and the time slot moved forward by an hour, so Ji Shang, who only appeared in Xianxiao's front hall at [-]:[-] p.m., obviously cannot be ruled out as a suspect.

Cao Weiwei continued: "The deceased had no poison, alcohol, or other drugs in his body. The cause of death is clear. He was stabbed in the chest and died of hemorrhagic shock. One of the stabs hit the left ventricle, which was fatal. The wound was wide on one side and wide on the other. Narrow and vertical, the murder weapon is presumed to be a single-edged knife with fine teeth, the blade is 10-15 centimeters long, and the maximum width is 3 centimeters."

"The blade has fine teeth?" Chai Lu repeated, "This kind of knife is not common at home."

Cibin nodded in agreement: "This kind of serrated knife is really not common in ordinary households. I know that chefs use serrated knives to cut frozen meat, and this type of knife is also used when cutting plants on outdoor adventures."

"From the perspective of length and width, it should be similar to a steak knife or a bread cutter." Yin Hao added.

Cao Weiwei knocked on the table and continued: "The victim had a hand injury on the right side of the face, and slight linear abrasions on the knees and palms of both legs. Water samples and plant tests confirmed that the place where the body was found was the scene of the crime. In addition, the test results of luminol showed that the victim was stabbed on the walking path four meters away, and then crawled to the green belt. The abrasions on the limbs were caused by crawling. Caused."

"Although the walkway at the side entrance of Binhe Park is very secluded, the chances of calling for help are higher than those behind the green belt." Ci Bin shook his head in puzzlement, "Why would the victim go to a more concealed place?"

Yin Hao hesitated: "Actually, this kind of behavior can also have a reasonable explanation."

Cao Weiwei nodded: "Continue."

Yin Hao said: "This just points out the characteristics of the suspect. There is a high probability that the murderer is related to the victim. They know, are familiar with, or even intimate, or for some reason the deceased is covering for the murderer."

Cao Weiwei: "So you must be very careful when investigating interpersonal relationships. In addition, no information about other people that can be collected was found on the surface and body of the corpse. This may be because of the heavy rain, or the murderer may have made sufficient preparations. Okay, important That's about all the information, each of you will talk about the progress of your investigation, and Cibin will come first."

Just as Ci Bin was about to stand up, the little stool raised his hand first: "Captain Cao, did you forget about tongue cutting and sunflowers?"

Cao Weiwei sneered: "I know that's where your kid's attention is. Sunflowers basically can't provide directional information, and sunflowers are everywhere this season. As for tongue cutting, although there are fingerprints on the face, there are no fingerprints. The murderer was wearing gloves. In addition, there was indeed a five-centimeter linear wound on the palm of the left hand."

Cao Weiwei picked out a photo of a knife from the data: "But there is one thing that is really strange. The incision on the base of the tongue has no lines, and it is a flat-edged knife. Diao Zhuzhu gave a photo of a amputation knife used in forensic medicine. She deduced that the tongue knife is similar to this Shape. The blade is thin and narrow, and it should be shorter than this, which is convenient for intraoral manipulation. In addition, the victim’s tongue was cut with a single knife, and the movement was fast and the incision was smooth.”

Yin Hao said thoughtfully: "It's strange that he carried two tools in the crime. The anti-reconnaissance awareness is very strong, it should be a deliberate murder. The tongue was cut accurately, but the stabbing was done twice. This seems a bit contradictory."

Chai Lu said: "It's normal, the tongue is cut off after death, and the dead person can't move, so the strike is of course accurate."

Ci Bin said: "There is a possibility."

Yin Hao didn't comment, and nodded hesitantly after a while.

Cao Weiwei sat down and looked at Cibin: "Cibin, come here."

Cibin said: "I didn't gain much here. The school is already on holiday, and only the teacher is checking papers at school. According to other teachers, the deceased was gentle and kind. The teachers who knew him spoke very well of him. Anyone had conflicts, and there were no financial or interest disputes, including students. Everyone who knew him expressed shock at what happened to him. In addition, surveillance showed that the deceased left the school at 05:30 yesterday afternoon."

Yin Hao raised his eyebrows, but didn't interrupt.

Cibin paused for a moment and then said: "The deceased's ex-girlfriend Chen Qianyi asked for a price today due to illness, so I went to her home. After hearing the news of Wang Jingping's death, Chen Qianyi almost fainted from crying. It seems that although the two broke up for two months, But Chen Qianyi still has feelings for the deceased. In addition, Chen Qianyi also left school at 05:30 yesterday, and then went straight home. After arriving home at 06:30, she did not go out again. This time was confirmed by her parents and nanny."

Cao Weiwei asked: "Did you ask Chen Qianyi why she broke up with the deceased?"

Cibin nodded: "The victim brought up the breakup because his mother, Wang Qin, was dissatisfied with Chen Qianyi. The two had a very good relationship. After Wang Jingping brought Chen Qianyi home to meet her mother half a year ago, their attitude began to change. Chen Qianyi said that Wang Jingping He is a bit of a motherly boy. Although Wang Jingping himself is aware of this and feels depressed at home, he just cannot resist his mother. Maybe it is a single-parent family, and the mother has paid too much for him. Because Chen Qianyi has always refused to give up this There was a relationship, so the two didn't finally break up until two months ago. Peacefully."

Cao Weiwei turned to Yin Hao: "Where are you?"

Yin Hao shook his head: "The time period of the victim's death has changed. Ji Shang needs to re-investigate him. I can't judge him at present. As for the mother of the deceased, the alibi is sufficient to rule out the suspicion. In addition, in Wang Qin's eyes, the 28-year-old His son is honest, obedient, suffers from losses, does not fight, is careful in everything, and will not conflict with anyone, and Wang Qin feels that this is the advantage she has cultivated for her son to be able to live and work in peace."

The expressions on the faces of everyone present have more or less changed, even Cao Weiwei smiled in disbelief.

Yin Hao flipped through the case materials, and continued: "Brother Ci's investigation results were cross-compared with Wang Qin's questioning. There are several doubts. First, Wang Qin reported that his son had broken up with Chen Qianyi half a year ago, not two months ago. Second, the victim was only half an hour away from his work unit to his home, so where else did he go between 05:30 and 08:30 in the afternoon? There is also no trace of his actions between 09:30 and 10:30 in the evening. Clearly; in the end, Wang Qin reflected that the scar on the side of his son's face was accidentally injured by a student while trying to persuade him to fight, but the school is already on holiday, where did the student come from?"

Ci Bin said: "You mean that the victim's missing two trajectories may be related to the student fight?"

Yin Hao nodded: "Maybe Wang Jingping lied to his mother, the injury was not caused by the student."

Cao Weiwei said: "Chai Lu, do you have any clues?"

Chai Lu shook her head: "I haven't got the bank statement yet, Wang Jingping basically has no Internet activities, and the communication records are also very clean. Except for his mother, he has hardly contacted anyone else, and he has very little contact with Chen Qianyi. But on the night of the incident, Chen Qianyi had I called Wang Jingping five times in a row, but Wang Jingping didn't answer any of them."

There are also two police officers who are responsible for supplementary search and inspection of the retrieved surveillance images, and they also said that no suspicious points have been found yet.

Cao Weiwei looked at the time, it was almost eight o'clock in the evening, she said: "That's it for now, everyone go home and rest first, and continue tomorrow."

Cibin stood up: "Captain Cao, the more I think about it, the more I feel that Chen Qianyi is hiding something. I plan to go to her house again right now."

Cao Weiwei nodded: "Bring someone with you."

Yin Hao said: "I will go with Brother Ci."

"go Go."

Cao Weiwei nodded: "After asking questions, go home and sleep quickly. It's a good thing to love work, but don't be like your brother who only knows about work, and you will become a single old leftover man."

Ci Bin said indignantly: "Captain Cao, if you cared so much about me before, I wouldn't be single now."

The small stool rested on Ci Bin's shoulders: "You don't want to eat the vinegar of the police grass, he is still fresh and tender now, after a few more years of hard work, after he becomes haggard, Captain Cao and the others will naturally climb the wall!"

Cao Weiwei jumped over Chai Lu, who was staggering from laughter, and slapped the back of the small stool with a slap.

Everyone laughed, and the atmosphere in the office finally relaxed a little.

The summer in the inland area is hot and scorching. I thought that a rain would cool me down a bit, but in fact, I only got the humid heat that could not dissipate for a long time, which made me even more depressed.

Just like this complicated and fog-shrouded case, it is a headache.

Yin Hao drove the car in silence, while Ci Bin recounted the case in his mind alone, both of them were afraid of missing something.

Suddenly, a phone ringing broke the silence in the car.

The strange number flashed on the screen for a long time, Yin Hao was inexplicably startled, and stretched out his hand to slide across the screen.

The other party: "Hi Officer Yin, I am Xianxiao's boss, Ji Shang."

Yin Hao raised his eyebrows, and Ci Bin also looked over.

Yin Hao: "Mr. Ji found the manuscript?"

Ji Shang: "Sorry, I haven't found the manuscript yet."

Yin Hao: "Then this call is..."

Ji Shang: "I just opened a courier package, and there are some strange things in it. I don't know if it is related to the case you are investigating."

Yin Hao: "What's in the package?"

Ji Shang paused for a moment.

"A bloody sunflower."
