Replace the evil way

In the conference room, representatives from all groups are present. He Wei is sorting out the clues of the falling building case. The detailed autopsy report has come out. The results of the autopsy are consistent with the conclusion of the preliminary autopsy on the spot. The deceased was indeed pushed down while he was alive. , is an out-and-out murder case.

He had a blow wound on his back and a occluded wound on his left forearm. According to the degree of subcutaneous bleeding and fracture damage, it was inferred that the damage was caused by a cylindrical metal stick, similar to a baseball bat or other murder weapon.Although no contusion was caused, the striking surface of the metal rod may have left the victim's skin tissue.

The trace inspection results showed that the thread on the button found on the roof was cotton fabric, and the half fingerprint belonged to the deceased Chen Lei, which was compared to the fingerprint of the right thumb; the half shoe print on the steps and the heel print on the corner of the wall , and a set of fingerprints on the railing, all belonged to the deceased.

"It looks like it's been premeditated for a long time. Did he still wear gloves and shoe covers to commit the crime?" Chongzhen asked, Zheng Youqing nodded: "It's possible, almost all the physical evidence we collected came from the victim, including the vent, Xiaoxiao Didn’t you go up to see it? No fingerprints were collected.”

"But there is hair." Yun Xiaoxiao turned sideways and complained to Zheng Youqing, "I picked it up from the bug's corpse!"

"Although it's disgusting, Xiaoxiao, the reality is cruel." Zheng Youqing handed the inspection report to He Wei, and He Wei opened it, and was stunned: "Chemical fiber?"

"That's right," Zheng Youqing shrugged, "That's not real hair, it doesn't have any biological information, it's a wig."

"The traces of the ropes found on the outer wall are all old, and they should have been left by repairing the air conditioner before. The murderer did not go through the outer wall." Hu Songkai said.

Xia Liang raised her hand: "I've been watching the surveillance three days ago, and I haven't found any suspicious behavior by the staff and residents of their hotel. The last call from the deceased's cell phone was to his wife at [-] o'clock, and everything else was for work. I didn’t find any conflicts with anyone.”

There was a brief silence in the conference room, He Wei stood up, picked up a marker pen and began to sort out the information he had so far on the whiteboard.There is no biological evidence of the murderer, not even a shadow. This person is as elusive as a ghost in a rainy night, invisible and intangible.

"Actually, it's not surprising. It's unlikely that the elderly are so strong that they can get into the vent." He Wei tapped the whiteboard with his index finger. It's more of a challenge, isn't it?"

The people in the conference room looked at each other, no, we just feel that we have no clue, and we don't regard solving crimes as a hobby, and we can't resonate with He Detachment.

"Xiaoxiao, Chongzhen."

The two people who were named agreed, and He Wei asked them to take two teams out, one to investigate Chen Lei's social relations, and the other to investigate whether there was anyone who matched the characteristics of the haunted old man.

"There must be something hidden in this carefully planned murder case. Go through all the villages within three kilometers of the hotel, so you don't miss anything."

Xiao Chen from the technical team came to knock on the door. The clothes of the deceased sent by Luo Ying were tested and the results were found. The tear marks on the neckline were artificially caused, and the scratches on the back were consistent with the rust on the railing. Infer the scene of Chen Lei's struggle before falling from the building.

"What about the half shoe print?" Hu Songkai asked, "He was fighting to escape, but he stepped on the steps with half of his foot and realized that this is the top floor? That's not escape, it's begging for death."

"This can be discussed in the throwing object experiment," He Wei put on the marker pen, "Go to the police academy to borrow a dummy of similar height and weight, and then go to the scene. Sister Lan, if you have nothing to do in the morning, you can come with us. "

After the meeting, Hu Songkai, He Wei and Du Ruanlan went to the parking lot together. Hu Songkai asked, "Are you driving or should I drive?"

"casual."

"Why hasn't Lao Zheng assigned you an assistant yet? You have to do everything yourself." Hu Songkai suddenly thought of something, and suddenly realized, "Oh, no, I saw Miss Zheng sticking to you to deliver things again this morning. Lao Zheng must have done it on purpose. To create opportunities for my daughter, I want to recruit you as my son-in-law."

He Wei told him not to talk nonsense, Zheng Youqing is fair and beautiful, and he is also the jewel in the palm of the city bureau chief, how many people break through the threshold, and who will get him.Hu Songkai grabbed his arm: "Don't you believe it! Really, I really feel that Lao Zheng has this meaning. If you become the son-in-law of the director, your future is limitless!"

Du Ruanlan listened with interest, and patted He Wei's shoulder: "Youqing is gentle and cute, and she is beautiful, so she is a good match for you."

"I don't have that blessing." He Wei got into the car, started the engine, and reminded, "Seat belt, bumping your head is not considered a work-related injury."

----

He Wei and Hu Songkai were on the top floor, dressing the dummy in the same style of shirt and trousers as the deceased, while Du Ruanlan was downstairs, waiting to observe the fall posture of the dummy and the distance from where it landed.

"The deceased was near the landing point and was attacked from the back, then turned around and raised his arm to block," Hu Songkai pulled the dummy's left arm up, "He wanted to escape, but he stepped on the steps and found that there was no way out. escaped, and was pushed down by the murderer?"

"Most people make the most favorable judgment based on their survival instincts at the moment of life and death." He Wei took the dummy over, "I think the parry injury occurs first, and the dead fights with the murderer, tearing off a button , and then wanted to call for help from the railing, and was attacked from behind."

The dummy was hanging on the railing with both hands, and Hu Songkai snapped his fingers: "The murderer wanted to push him down, he was struggling, and he stepped on it to find a support point!"

He Wei nodded, and simulated the scene with Hu Songkai. After pushing the dummy down, Du Ruanlan's cold voice came from the intercom: "No, there is a deviation in the landing point, in front of the flower bed."

The dummy was brought up again, and Hu Songkai changed the method, instead of pushing his back, he threw it down with his neck upside down, but the landing point was still wrong, and the deviation was even greater.He Wei rubbed his chin: "He raised one foot as a support, right? If the suspect can't push him off from behind like we tried, and can't lift him up and throw him down, then there is only one foot left. way."

Hu Songkai understood again, and lifted the other leg holding the dummy this time, and lifted it off.He and He Wei looked down together. After Du Ruanlan checked, he made an "OK" gesture. That's how the person fell, and the slight data deviation can be ignored.

Hu Songkai wiped the sweat from his forehead: "It seems that the murderer is a man. It is not easy for a petite woman to throw a big man off in this posture."

The hotel is closed today, only security guards are on duty to patrol.The owner of the hotel, Pan Pinghai, is a middle-aged man in his 50s, with a crew cut, dark and thin.He was the cousin of the deceased, and on behalf of the relatives in the family, he came to ask how the case was going.

"The case was solved in just a few hours?" Hu Songkai looked at him, "Why didn't you come at night?"

Pan Pinghai hurriedly explained that he just came back in the morning after going out to other places, and when he got home, he heard that his nephew had an accident in the hotel, and he was very frightened.Hu Songkai asked some basic information, and He Wei called the security guard surnamed Li over: "How is the relationship between your boss and the manager?"

"The boss doesn't come here very often. The manager of our hotel is in charge," Li Baoan said mysteriously. "However, they were arguing in the office a few days ago. I heard the boss scolding the manager. It seems that something is wrong."

"Chen Lei filled his pockets?"

Li Baoan shook his head: "I don't know about this, I'm just a little security guard, how can I know how to lead those little Jiujiu."

He Wei smiled, and the security guard also showed a simple and honest smile.After Hu Songkai's questioning was over, he went back with He Wei. The two exchanged opinions on the road, and mentioned the conflicting points about finances. Maybe they can dig down along this line.

Back at the bureau, Xia Liang came to report that he had seen the surveillance from a week ago, and finally found something wrong.

"He Detachment, look," Xia Liang pointed at the screen that was divided into two parts, "The one on the left is from before April 4th, and the one on the right is from April 7th to the present, isn't it different?"

He Wei squinted his eyes, and quickly noticed the difference.There is a deviation in the position of the camera search. Although it looks like a corridor at first glance, if you look closely, you can still find that the camera after No. 7 has moved to the right.

"I'm used to paying attention to the edges and corners when I look at things. On the day of the 7th, there were suddenly more stairs and corners below. Only after comparison did I find that the camera was passive."

He Wei reached out and patted the top of Xia Liang's head: "That's right, young people have good eyesight. Are they on every floor?"

Xia Liang nodded, every layer is the same, all moved to the right by a small angle.He Wei picked up his jacket, and Hu Songkai unscrewed it just after he came back from buying a bottle of drink from the canteen, and He Wei took it away: "Erhu, go to the hotel again."

After speaking, he unscrewed the bottle cap and took a sip, frowning: "Why do you buy peach flavor? It's so sweet."

"...Damn it, did you learn from the Heng bandits next door?" Hu Songkai said viciously, "I drank it!"

He Wei stared at him, his eyes made it clear that he didn't want to talk to him, so without talking nonsense, he took him and Xia Liang to Shengshi Hotel again.Seeing the police car turning back, the security guard scratched the back of his head: "Comrade policeman, why are you back again?"

He Wei locked the car: "It's nothing, just borrow your security room."

---

He Wei and Xia Liang were watching the surveillance in the security room, while Hu Songkai was in the corridor, clinging to the wall, groping for the blind spot of the surveillance.

"Erhu, move a little further to the left, yes, retract your head further, what is your position now?"

Hu Songkai clings to the wall, struggling to hold the walkie-talkie: "I am completely stuck to the wall now, like a gecko. It is too strenuous to walk down in this posture, but if you are familiar with the terrain, you should be able to walk very quickly."

"You go through the first floor."

One minute later, Hu Songkai walked from the first floor to the second floor, but his figure did not appear in the surveillance.Li Baoan, who was watching the excitement, exclaimed: "Oh my god, can you hide like this? It's the first time I've seen it!"

At present, the criminal suspect's modus operandi can be preliminarily determined. He Wei wrote down several key information: male, short in stature, with some martial arts skills, familiar with the hotel's internal facilities, thoughtful, and with certain anti-reconnaissance capabilities.

Yun Xiaoxiao and Chongzhen's investigation work also had some clues. After returning, the two said at the same time: "There are important discoveries."

"Xiaoxiao speak first."

"Yes," Yun Xiaoxiao opened the palm-sized notebook, "Chen Lei's family relationship is not harmonious. His wife Wang Cui has a lover outside. I heard from neighbors that they often have trysts while Chen Lei is on the night shift. Last night there was a black Buick. Stop at the intersection of his house, it belongs to that lover."

"Have you found out who owns the car?" He Wei seemed to think of something, "We went to the hotel and saw a black Buick."

Yun Xiaoxiao nodded: "Captain, you guessed right, Wang Cui's lover is the owner of the hotel, Chen Lei's cousin Pan Pinghai."

Unexpectedly, this family is so complicated. The cousin and the younger daughter-in-law got together. The key is that the neighbors around seem to know the inside story. Not only do they have no plans to divorce, but they can coexist peacefully under the same roof. It is really amazing.

He Wei didn't have any sense of surprise. He has been in the police force for many years, what kind of things haven't he seen?There was another case last year. The son liked his mother, was jealous of his father, and stabbed him to death with a screwdriver in the middle of the night.

He recalled Pan Pinghai's appearance. He was dark and thin, and he was still a hotel owner. He had emotional and financial disputes with the deceased, so there was indeed a possibility of committing the crime.However, based on his intuition in handling the case, He Wei always felt that there was something wrong with it.

"Old He, listen to me, this is an unexpected harvest." Chongzhen took out a photo and handed it over. In the photo is a white-haired old man who is already very old and energetic, but the photo is black and white , at first glance it looks more like a posthumous photo.He Wei asked, "Who is this?"

"Wang Fusheng, who lived in Wangjiawa near the hotel, lived alone. Half a year ago, he was killed while picking up waste. His family members were all in the city. No matter whether he died, he never showed up. It will be paid for." Chong Zhen continued, "There was no probe on the country road where the accident happened, and it was midnight, and there were no witnesses, and the village police station could not find the vehicle that caused the accident. It's stuck there and no one cares."

"It's just that people didn't catch it all the time, right?" He Wei took the photo and frowned, "He is the one who is haunted?"

"According to the records of the hotel staff, he fits the description. This photo was given to me by the village committee. You see, he is wearing a Chinese tunic suit. The ghost they saw was also wearing a Chinese tunic suit. He must be right."

The news brought back by Chongzhen caused a qualitative change in the direction of the investigation of the case. A case that might have been a murder of love turned into a revenge case, and the span was too great.He Wei flipped through the notes he had made before, and asked Yun Xiaoxiao, "Does Chen Lei have a car at home?"

"No, but his yard is quite big, so you can park your car. I also saw glass water, car wax and other car supplies."

"Okay, Xiaoxiao, you and Xiaoxia go to the line with Wang Fusheng, and find out his recent whereabouts." He Wei picked up the car key, "Let's go, Chongzhen, I'll run with you instead. .”

---

Wang Cuisu opened the door facing the sky, her eyes were bloodshot, and there were several large bags piled up in the living room, all of which were Chen Lei's belongings.She packed it up overnight and burned it together when preparing for the funeral.

"It was tidied up so quickly?" Chong Zhen flipped through the bag, "Yo, the razor and toothbrush are all in there, so nothing was left behind."

Wang Cui smiled awkwardly: "Everyone is gone, it's boring to keep it, the more you look at it, the easier it is to think."

Chong Zhen saw that she was crying bitterly in front of her face last night, and now she looks like a normal person, thinking that this couple really has no feelings for each other, and that they have not divorced may be out of consideration for their children and face.

He Wei came here this time mainly to ask about the car.According to his way of thinking, since it was a ghost asking for his life, it must have something to do with the traffic accident, otherwise there would be no such thing as taking his life.Wang Cui said that there used to be a red BYD scooter at home. Chen Lei wanted to change it half a year ago, so he sold it. He never found a suitable one, and the car purchase plan was temporarily put on hold.

"Who did he sell the car to?"

"It was sold in the city, and I kept the invoice." Wang Cui searched in the room for a while, found out the invoice for the car sale, Chong Zhen kept it, and set off to the auto repair shop with He Wei.

The little girl with shofar braids was jumping rope carefree in the yard. Seeing Chong Zhen and He Wei, she ran over: "Uncle, where is my father?"

Chong Zhen knelt down/body and stroked her hair: "Didn't Mom tell you? Dad has gone far away, and I don't have time to go home for now."

The girl shook her head: "Mom said Dad won't come back, she won't cry for me, let me forget about Dad."

Chong Zhen and He Wei looked at each other, feeling sorry for this kind of marriage that existed in name only, and this child lived in such an environment since he was a child, so he wondered if he would have psychological shadows.

The car repair shop on the invoice is in the suburbs of the city, in the economic development zone, and it is a private car beauty shop.After seeing the invoice, the shop owner immediately remembered: "Yes, this is the car that Chen Lei sold to us half a year ago. His car was crashed before, the bumper was changed and the front panel was made, and then he wanted to sell it again. If it wasn't for the low price , we are not willing to accept."

"What happened?" He Wei took out a pack of cigarettes and gave one to the shopkeeper. The shopkeeper nodded and stooped to take it, and lit it up: "He said he was driving in the countryside and hit and killed a sheep raised by others, and he even paid a sum of money. , Later, I felt unlucky, so I wanted to sell the car and buy a new one."

Chong Zhen smiled: "You really believe it?"

"Why don't you believe it, old acquaintance, all the maintenance of his car is done in our shop, and he is a regular customer."

He Wei asked him if he had sold the car and to whom.Coincidentally, the one who bought the car was a car repairman in their shop, trying to buy it cheap and go home instead.The car repairman took the two police officers to the house. The red BYD was parked at the door. The inside and outside of the car were cleaned up, coated and waxed, making it look like a new car.

"Have you changed the parts since you bought it?"

"No, no, I repaired it before. Except for the bumper replacement, there is no other problem with this car. It drives very well!"

"That's good." He Wei took out his mobile phone to make a call, "It's much more convenient if the big parts are all there."

---

In the repair garage, Zheng Youqing was wearing a mask and holding a watering can, which contained the prepared luminol reagent.The bumper of BYD has been removed, and what she needs to test is whether there is a blood reaction in the front of the car, and if there is, DNA will be extracted from the occult blood test material for typing.

After spraying, Zheng Youqing stood up and gestured, and the staff of the car repair shop at the door pulled down the shutter door.All of a sudden, the light in the garage became dim, and the front of the vehicle showed fluorescent reactions in the form of dots and flakes, and the distribution was concentrated above the bumper.

Xiao Chen took out his camera to take pictures, and Zheng Youqing took a cotton swab and quickly wiped the light-emitting area.He Wei asked: "Half a year has passed, what is the success rate of DNA extraction from the deceased?"

"The occult blood test material contains less blood traces. This kind of small carrier is purified and extracted by M48 magnetic bead extraction method, and the type can generally be detected." Zheng Youqing did not delay work at all when he spoke. Half a minute later, the fluorescent reaction Gradually disappeared, she sealed the wiped cotton swabs and put them in the evidence box.

The store manager and the car repairman panicked: "Didn't you kill a sheep? How, how could there be a dead person?"

Zheng Youqing took off her mask and smiled, "I'll know if it's a sheep soon." She was carrying the evidence box, "What else do I need to do? If it's okay, I'll go back to the bureau and find Sister Lan for extraction."

He Wei told her to go back early and pay attention to safety on the way.Although the results haven't come out yet, He Wei already knew that Chen Lei was the driver of the accident after seeing the reaction of the luminol reagent. After he escaped, he sold the car to an acquaintance, thinking that he would be able to hide the truth without anyone noticing.

But what is puzzling is that Wang Fusheng's family members are all in the city. They don't usually contact the old man, and they don't even look at him when he dies. How could he want to avenge him?His ashes were stored in a small funeral home in the township, and the storage fee was also paid by the village committee. If there were really someone so close to him, why didn't he even claim the ashes?

"Is it possible that there are two people pretending to be a ghost and the murderer?" Chongzhen guessed, "Maybe the old man was hit to death, someone pretended to be a ghost, and then the murderer followed suit, just to disguise the murder as a supernatural event, killing two birds with one stone."

"There is such a possibility, so Wang Cui and Pan Pinghai haven't cleared their suspicions yet." He Wei took Chongzhen's arm, "Get in the car and go to Wang Fusheng's house to have a look."

With the help of the Wangjiawa Village Committee, He Wei and Chongzhen found the house where Wang Fusheng lived before his death.This is a dilapidated small tile-roofed house. The roof is not even covered with tiles, and it is completely covered with plastic sheets. Compared with the surrounding two-story buildings, it looks too shabby.The director of the village committee revealed that Wang Fusheng's son kept it here to wait for the government to demolish it, otherwise the dilapidated house would have been demolished long ago, and the three mu of land would be sold to the family who built a greenhouse next to them to grow vegetables.

Wang Fusheng makes a living by picking up scraps. His house is bare and his daily necessities are very simple. The only appliance in the house is a broken electric fan.Chong Zhen lifted the quilt, and a burst of pungent dust hit his face, he coughed twice, and swept the dust away with his hands in the air a few times.

They rummaged through the house, and the director of the village committee was holding the key at the door. He Wei chatted with him while looking for clues, and listened to all the gossip in the nearby villages.

"...Wang Cui is also from our Wangjiawa. She married into Chenjia Village and lived a restless life. We village cadres know everything about her. Pan Pinghai's wife, Chen Chunhua, has come to our village committee four or five times to make trouble. Let us It's up to us, we can't control it..."

"Then you all worked hard." He Wei bent over, and when he saw the flashlight, he found a few pieces of paper stuck between the bed, "Chongzhen, come here, there's something here."

The few pieces of paper were taken out from the crack of the bed, and they turned out to be remittance slips.The money was remitted at the post office in the town. The remitter was Wang Fusheng, and the payee was a person named "Chen Gui", whose address was in Pingchuan City.The remittance time varies every year, and the amount is not much. It is about [-] each time, but given Wang Fusheng's economic conditions, the [-] is at least his long-term savings from picking up scraps.

The director of the village committee didn't know who this "Chen Gui" was. They didn't have anyone with this name in Wangjiawa. You can go to Chenjia Village ahead to have a look.Chongzhen frowned: "This case is getting more and more complicated like a ball of thread, and we still need to ask the Pingchuan City Bureau to cooperate in handling the case?"

"Isn't that the case when you're doing criminal investigation on your first day? There's less running around?" He Wei pinched the remittance slip. "

Chongzhen put a cigarette in his mouth: "It's been a long time since I've been in touch with him. On the day of his wedding, I caught an armed robber in Sichuan, but I failed; on the day of the child's full moon wine, you detained me outside the nightclub If you are a squat, release the pigeons twice, I don’t have the nerve to ask for help.”

He Wei smiled: "Special circumstances are treated specially. We are criminal police, and we come to the task as soon as we say it. When my mother was over [-], I was still in the branch office. On the way back, I was robbed with a knife. Not only did her birthday fail , I went to the hospital, and she was so angry that she ignored me for half a month."

Chongzhen sighed: "Do what you do and love what you do..." He dug out the classmate's number, went to make a call under the big banyan tree, and came back after a while: "Go check it out, and let me know if you have any news."

It was getting late, He Wei drove Chongzhen to the direction of the dormitory, Chongzhen was surprised: "You workaholic, don't you go back to the bureau?"

"Go back and take a shower." He Wei rubbed his neck, "I forgot the time when I was handling a case in the bureau, and I haven't washed for two days."

"It's only been two days before I have to wash it?"

"..."
