Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Li Chenggang threw his head back and laughed, his laughter full of madness and despair: "Hahaha, I knew I couldn't avoid it, I couldn't avoid it... Fine, I said, we're all going to die anyway!" He put away his smile, his eyes became sinister, and began to recount the bloody past.

"That bitch Wang Tingting owes me 150,000 yuan and she can't pay it back. I was just trying to scare her, asking her to sell herself or find a way to pay back the money, but she told me that Zhang Haiyan knew about her loan sharking and said she would tell her boyfriend Zhao Yang. I got anxious when I heard that. Zhao Yang is a fitness coach with a muscular body. If he really knew, he might fight me to death. And if this matter gets out, who will dare to borrow money from me in the future? How can I run my business?"

Li Chenggang licked his cracked lips and continued, "I told Wang Tingting to ask Zhang Haiyan out. As long as the job is done well, the debt will be written off. The woman was hesitant at first, but she couldn't stand my daily threats and finally agreed."

"That morning, Wang Tingting asked Zhang Haiyan to meet her at a coffee shop and gave her a drink mixed with chloroform. After Zhang Haiyan passed out, Wang Tingting called me. I drove over in a truck and moved her into the car. Zhang Haiyan was still conscious at the time, struggling non-stop and begging me to let her go." A barely perceptible panic flashed across Li Chenggang's face. "I was afraid that she would scream for help, so I covered her mouth with a towel and strangled her neck. I didn't want to kill her, but she struggled so hard that by the time I realized what was happening, she was already dead..."

At this point, Li Chenggang suddenly fell silent, and the only sound in the room was his heavy breathing. Wang Shuai patted the table and said, "Go on!"

Li Chenggang gritted his teeth and continued, "The person was dead, so I had to do it once and for all. I drove back to the laundry warehouse, found a saw, and cut up the body..." He closed his eyes, as if he didn't want to recall the bloody scene, "After cutting up the body, I wrapped the body parts with waterproof cloth. I thought the sewers were interconnected and under construction, so the body would not be found for a while if thrown in, and even if it was found, it would be difficult to trace it."

"Why did you choose to dump the body in the sewer?" Lu Chuan asked.

"My brother works in a laundry factory, and I know that the factory's trucks often deliver goods to that area. I took advantage of the dead of night, drove the truck, and threw the body parts into different inspection wells one by one. I also used the factory's detergent to clean the scene and the truck, but I didn't expect that you would still find it." Li Chenggang smiled bitterly and shook his head, "I thought I did it perfectly, but God, he didn't let me go..."

"And what about the 80,000 yuan in hush money Wang Tingting received?"

"That was hush money for her, so that she wouldn't tell anyone about the matter. I was also afraid that she would not keep her mouth shut and ruin my business. After giving her the money, I also warned her that if she dared to call the police, I would not let her go even if I became a ghost." After Li Chenggang finished speaking, he slumped in the chair, as if all his strength had been drained.

Outside the interrogation room, the sky gradually brightened. With Li Chenggang's confession, the truth of this corpse dismemberment case that shocked the whole city finally came to light. What awaits Li Chenggang and Wang Tingting will be the most severe punishment of the law, and they will eventually pay a painful price for their actions.

Although this case was really handled, the Criminal Investigation Detachment was faced with cases one after another. Just three days later, the Criminal Investigation Detachment received another related report.

It was afternoon when the alarm was received, and the steaming summer air, wrapped in the chirping of cicadas, poured into the duty room. Lu Chuan grabbed the tactical vest and put it on. Zhang Hui's slightly hurried voice came from the intercom: "The reporter said that a body was found in the middle of Luoying Valley. There were signs of dragging at the scene, and the deceased had a hemp rope wrapped around his neck." On the winding mountain road, sirens tore through the sultry air. Lu Chuan was holding the steering wheel. In the rearview mirror, Yang Lin and Yang Sen were sorting out the survey box. The metal shell of the portable multi-spectral imager was shining coldly in the sun. Half an hour later, the police car stopped at the entrance of the valley. From a distance, several tourists were seen sitting on stone benches with pale faces within the cordon. Zhang Hui was holding up a notebook and asking questions patiently.

"The body is in the shallows 300 meters downstream." Zhang Hui walked up quickly, beads of sweat still hanging on his forehead. "The people who reported the case are a group of hikers. They said they were going to explore caves upstream, but they found traces of dragging grass in the bushes and followed the traces to find the deceased." He handed over his mobile phone, and on the screen were photos of the scene taken by the person who reported the case - a body in an outdoor jacket half-immersed in water, the hemp rope at the neck deeply cut into the flesh, forming purple-black bruises on the pale skin.

Lu Chuan put on latex gloves and said, "Yang Lin and Yang Sen, conduct an on-site investigation immediately. Zhang Hui will continue to question witnesses, focusing on the specific route where the body was found." Before he finished speaking, the two of them were already walking quickly towards the scene with their investigation boxes on their backs. Yang Sen took out a laser rangefinder, and the red beam shuttled through the weeds: "The dragging trace is about 15 meters long, and the grass blades at the starting point are broken in the northwest direction." He squatted down and picked up half of a mud-stained mountaineering buckle with tweezers, "C-type lock buckle, commonly found on outdoor backpacks."

Yang Lin deployed a 3D scanner, and a green laser grid instantly covered the entire area. "The deceased was lying prone, his clothes were torn in many places, and there were obvious abrasions on his right hip." He switched to ultraviolet mode, and light blue fluorescent footprints immediately appeared on the shallows. "The BHT fluorescent agent showed that the murderer cleaned the scene but ignored the gravel on the river beach."

On Zhang Hui's side, the hiker Xiao Wang who reported the case was still shaking: "Our team leader was the first to notice something was wrong with the grass. The grass fell too neatly, it didn't look like it was blown by the wind." He pointed to a broken branch in the bushes, "From there, there is an indentation leading straight to the river. Oh, right! We also heard a metal collision sound, about 20 minutes before the body was found."

"What kind of metallic sound?" Zhang Hui's pen tip hovered over the notebook.

"Ding-dong-dong," Xiao Wang imitated, "It sounds a bit like the sound of a mountaineering pick hitting a rock, and it went on and on for several times."

At this time, Yang Sen suddenly raised a high-intensity flashlight: "Look at this!" The light beam swept across the rocks on the river bank, and a fresh scratch glowed white under the ultraviolet light. "The scratch is 3 mm deep, and there is metal residue on the edge." He took out a metallographic microscope to observe, "The carbon content is 0.45%, which is consistent with the material of the steel pipe weapon before."

Lu Chuan squatted beside the body, illuminating the neck of the deceased with a tactical flashlight. "The rope groove is closed, and there are obvious signs of life on the edge, indicating that he was strangled before death." He turned to look at Yang Lin, "Extract fingerprints and DNA immediately, and check the deceased's personal belongings."

Yang Lin opened the deceased's backpack and found the cell phone in the waterproof bag had become hot from the river water. He put on anti-static gloves and took out the SIM card. (End of this chapter)
