traces of all things

When Lu Zheng arrived at the scene, the body was still lying there. From a distance, he was a thin and thin man, wearing a white T-shirt and "stealing potatoes" shorts with many pockets, lying on the ground, blood gurgling from his body. Down meanders down.

The onlookers were on the third floor and the outer three floors. This is a downtown area, and when the accident happened, it happened to be six or seven o'clock in the evening. The sun had not completely set, and the temperature had already dropped. The road was full of people who had a good dinner and went shopping. , There are several restaurants in this area, which are also overcrowded.

After the passage to the scene was opened, Lu Zheng and the others hurried in, and saw a small glass cart with the words "Tobacco, Alcohol and Beverage" stuck on the crime scene in front of it with red tape. There were some loose cigarettes on the cart. , beer, and some snacks and snacks. This kind of stall is not uncommon in the urban area of ​​Yuanbao, and there are several on the road.

"This is a product of the reemployment support policy for laid-off workers. It is actually quite convenient. Some even add a small pan to sell some scones and roasted wheat." Cha Qing said, sighing, and cleared a way Let Lu Zheng, Tang Shaoyuan, and Wei Xiongfeng go in first.

The deceased was confirmed dead. Lu Zheng stepped forward to check the wound first. On the side of the deceased's head, there was a small black round hole near the temple, and there was still a lot of coagulated blood on the edge of the wound.

"This wound..." Lu Zheng frowned slightly, and pouted in Tang Shaoyuan's direction. Tang Shaoyuan came up to observe together quite tacitly, and gave a definite conclusion: "This is the muzzle caused by long-distance shooting. When it comes to specific numbers, it should be at least ten meters or more.”

Wei Xiongfeng took pictures with his SLR, and sighed while taking pictures: "This murderer has good marksmanship, isn't he? He killed him with a single shot from more than ten meters away."

"It wasn't a shot." Captain Cha Qing looked very serious: "When the masses called the police, they said that there were three or four shots in a row. Before they could react, he saw the small tobacco and alcohol vendors throwing themselves off their stools. On the ground, a group of people did not dare to approach, so they called 120 and 110. When 120 came, they found that the victim had been shot and died on the spot. He had no vital signs. The police had sealed off the surrounding area and were dispersing the crowd. .”

"Three or four shots? It's pretty good without training." Lu Zheng frowned and observed the temple on the other side of the corpse.

"The bullet should still be in the body." Tang Shaoyuan helped him out: "There is no exit."

Lu Zheng nodded, and handed the scene to him: "It's you, I'll check the peripheral scene."

According to Captain Cha Qing, the peddler was sitting on a stool next to the glass trolley when the accident happened. Lu Zheng estimated the peddler's height, wrote and drew in the notebook according to the angle of the wound, and looked up. His eyes focused on a half-demolished real estate on the side of the road.

"Captain Zha, the bullet is most likely fired from the second floor of that building over there."

After hearing this, Zha Qing didn't ask why, and hurriedly mobilized armed criminal police to seal the building to find the murderer.

Lu Zheng was not idle while waiting for them to clear the scene. He buried himself in searching around the scene for a long time, and finally found what he was looking for on the side of the curb.

"7.62 mm caliber bullets, three." He spread his palms, took out a magnifying glass from the box and looked at the bullets intently for a while: "There are no rifling marks, they are earthen guns."

"Is it the same as the previous one?" Tang Shaoyuan finished examining the corpse and directed the police to bag the corpse and transport it to the physical evidence center. Now he freed his hand and asked while taking off his gloves.

"Probably, but I can't be sure for the time being. The shell case should be found at the scene, and it can be confirmed with the shell case." Lu Zheng shook his head, put the bullet into the evidence bag, and looked worried.

If so, this is likely to be a serial murder case, and the murderer has a hot weapon on his body, which may cause greater security risks to the society at any time.

Clenching the evidence bag tightly, Lu Zheng took a deep breath. At this moment, the mobile phone in his trouser pocket vibrated.

"Hello, boss?"

On the other end of the phone was Geng Zhizhong, who went to investigate the scene with Zha Qing: "Lu, bring Xiao Tang and the others together, and we have found the place where the murderer is guarding. It is on the second floor of the unfinished building next door, go upstairs and go left."

**

The murderer chose the location of the murder very cleverly.

Originally, there should not be such semi-abandoned buildings in the downtown area. It turns out that this area is one of the districts with the densest population and the most complicated population structure in Yuanbao City. The government plans to build a library here, but it is just negotiating conditions with the residents. Problems arose in time, and some residents became stuck households and refused to move out. Helplessly, the half-demolished construction site had to temporarily suspend work, resulting in the current embarrassing situation of half-demolished but not demolished.The right side of the building has been demolished and only the cement structure remains, and the residents have all moved out.However, since it is the peak time for eating after work, the only way to enter this half-destroyed building is a small road with a huge flow of people and vehicles, which leads directly to several large private enterprises behind, entering and exiting. There are too many people, and no suspicious person can be found for a while.

Lu Zheng and Wei Xiongfeng checked the monitoring distribution on the road they must pass, and found that there was only one intersection.

"Da Yin lives in the city, this murderer is a bit of a headache." Wei Xiongfeng didn't find any more surveillance probes, and his face looked very regretful.

The second floor had been demolished and only the concrete frame was left. Lu Zheng and the others went up the stairs in three steps and two steps. At the corner of the second floor, it was easy to find the policemen who had gathered to protect the scene.

"Come and have a look, Lu." Geng Zhizhong waved at him with some joy on his face: "There is a lot of dust here, there may be some good things."

The good things Geng Zhizhong said were probably fingerprints and footprints. For the trace inspection, they were indeed good clues and couldn't be better. Lu Zheng's mood brightened instantly, and he quickly entered the scene.

The furniture, floors, etc. in this empty room have been removed long ago, but the windows are still there.After Lu Zheng entered, Geng Zhizhong and the others spread out to make room for him.

Soon, there was a discovery on the ground.

Lu Zheng whistled "咻——" and said, "Harvest, Daxiong, come and take a picture and fix it."

**

In the small meeting room of Yuanbao Municipal Bureau, the case analysis meeting is being held.

The first person to speak was Captain Cha Qing, who was investigating the victim's identity. He turned on the projector with a stern expression, and put a household registration information form on it.

After a moment of silence, Captain Zha spoke.

"Lai Feng, according to the information on his ID card, male, 34 years old, from Shanghai, self-employed." At this point he paused subtly: "After contacting, we found the real Lai Feng himself, he I am still in Shanghai Province and have never been to Province A."

"This fake Lai Feng has a three-wheeled motorcycle used to transport stalls. According to the inspection, the three-wheeled motorcycle is a stolen vehicle. The original owner and Lai Feng do not know each other. Lai Feng's mobile phone number has also not been verified by real name. There is only one Wechat software, and there is no historical record, but there are more than 2 yuan in his Wechat account, which was remitted multiple times, and each amount ranged from 400 to 1000 yuan."

What Captain Cha Qing said caused huge waves in the entire conference room.

A fake Wei Chunhua just appeared, and now there is another fake Lai Feng. Both of them were shot dead within 24 hours. It is really impossible not to arouse suspicion.

While everyone was whispering, Wei Xiongfeng went up with the computer. Lu Zheng checked Wei Chunhua with him before, and now he has experience in checking Lai Feng's behavior. He clicked on a collection of videos and quickly zoomed in to The top corner played.

"Our surveillance video team found the Tianyan probe near the stall where Lai Feng bought cigarettes, alcohol and drinks. The probe took pictures of the whole incident, which was consistent with the testimony of the witnesses at the scene. By two hours, we discovered some suspicious behavior of Lai Feng."

While talking, the surveillance video was playing. At this moment, the upper right corner showed that it was around 03:30 in the afternoon. A man walking in a hurry, holding an umbrella even though it was not raining, walked by and stopped beside the small vendor. When he came down, he seemed to be shopping, but after communicating with him a few words, Lai Feng gave him a pack of cigarettes, and at the same time, he took out a small drawer with his right hand concealedly, and handed over something together with the cigarette box .

Wei Xiongfeng nimbly pressed the pause button, his hands flew like flying, zoomed in and zoomed in clearly again, and now it was obvious that what Lai Feng put on the cigarette box and handed over together was a small white square packet.

"Fuck, another drug dealer!" A burly investigator sitting next to Lu Zheng poohed angrily.

Drug trafficking + unknown identity + shooting to death, these two victims can basically be sure that there is some kind of connection.

At this point there is only one decisive piece of evidence.

"Leader Lu, how is your side?" Captain Cha Qing seemed to be full of hope for Lu Zheng's side.

When Lu Zheng heard this, he got up and stepped forward, quickly took out a few photos from his notebook.

"First of all, this is the shell casing we found in the car in Wei Chunhua's case. It was fired from a 7.62mm soil gun." Lu Zheng stood at the front and put the first picture on the projector The photo was followed by a second one: "This is the bullet casing found at the scene of the suspected murderer's shooting in the tobacco and alcohol vendor Lai Feng's case."

He put the two photos together with his fingers: "By comparing the firing characteristics of the firing pin, the grappling hook, and the trace characteristics left by the bolt, it can be determined that these bullets were ejected from the same gun. Those who killed Wei Chunhua and Lai Feng should be able to identified as the same murderer."

"Joint cases..." Cha Qing muttered to himself, tapping his fingers on the table irregularly.

"At the same time, two traces of physical evidence were found at the shooting scene - a few delaminated shoe prints, and six cigarette butts." Lu Zheng removed the previous two photos and replaced them with two new ones, with a twitch at the corner of his mouth. : "These two traces and physical evidence are very interesting."

He first stretched out a slender finger, and clicked on the reduced-layer shoe print: "This is the footprint of a man in his 40s, with a height of about 170, a foot size of 41, and a medium weight. Not equal, according to the footprints, the suspect's big toe base force is not obvious, which caused the contact area of ​​the left foot to become smaller and the stride length shortened, so the suspect is likely to have a missing or disabled left big toe! "

The spirits of the people in the house lifted.

"What's even better is these cigarette butts - these cigarette butts are very fresh, and the filters on them are also soaked in saliva. We have taken samples and sent them to the DNA laboratory. At the same time, they were also sent to the son of Wei Chunhua's boyfriend Sheng Wenhao. DNA, results will be available soon.”

The corner of Captain Cha Qing's lips twitched in the audience, showing a determined smile.
