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

His fingertips touched the metal object and his face turned pale instantly - the lighter with a sailboat pattern on it was now lying among the dead leaves, covered in mud.

"Take it back for physical evidence identification." Lu Chuan turned to look at Li Qiang, "Is there anything else missing?"

Li Qiang sat slumped on the ridge of the field, staring at the smoke in the distance in a daze: "No more. After Chen Hu drove away, I walked three kilometers along the canal and changed clothes under the stone bridge." He tugged at the collar of his prison uniform, "I planned all this alone, it has nothing to do with Chen Hu."

The sun gradually sank to the west, and the cornfield was dyed dark red. When Li Qiang was escorted back to the police car, he suddenly looked back at the place where the body was dumped, and said with his Adam's apple rolling, "Old Zhao, I'm sorry." The moment the car door closed, these words disappeared in the evening breeze, leaving only a field of broken corn stalks, silently telling the truth in the twilight.

The investigation process of these cases was relatively complicated, but Lu Chuan and his colleagues still completed the investigation. For Lu Chuan, the recent cases were relatively difficult, especially in determining the identity of the deceased. Lu Chuan and his colleagues did spend a lot of time and effort.

After the relevant cases are reported to the superiors, the Criminal Investigation Detachment is also responsible for the follow-up work of the case until it is heard in court, which is when it is considered completely over.

However, just before October, when the final cleanup work of this case had not been completed, the Criminal Investigation Detachment received another case.

The gloomy sky was very low, and dark clouds were rolling overhead, as if a rainstorm would pour down at any time. Lu Chuan's police car drove towards the construction site at lightning speed, and the sharp sound of the sirens cut through the dull air. As soon as the car stopped, Lu Chuan was the first to open the door, his black windbreaker rustling, and his eyes were sharp as torches, scanning the scene.

Yang Lin and Yang Sen quickly took out the investigation box from the trunk and walked quickly towards the sewer where the body fragments were found. Wang Shuai went straight to the pale-faced construction workers who were surrounded outside the cordon, and Zhang Hui followed closely behind, ready to record key information at any time.

"Master, don't be anxious, talk slowly." Wang Shuai tried to speak softly to comfort the trembling worker Lao Li who called the police. Lao Li wiped the cold sweat from his forehead, his voice trembling violently: "I... I just followed the construction team to dredge the sewer. At first, everything was normal, but the iron hook hooked up something slippery, I thought it was a rag." He swallowed, his Adam's apple rolling up and down, "When I pulled it up, my God, the bag was full of bloody meat and hair..." At this point, Lao Li's face instantly turned purple, and he turned his head away and retched.

Wang Shuai patted him on the back and continued, "After the discovery, did anyone else move at the scene? Did anyone suspicious approach?" Lao Li calmed down and shook his head, "No, we were all scared and quickly retreated here, waiting for the police to come. We didn't dare let anyone get close. But..." He frowned, as if trying to recall, "When I was leaving work yesterday, I seemed to see a white van circling around for several times. I didn't pay much attention to it at the time, but now I think it's a bit strange."

While Wang Shuai was asking questions carefully, Yang Lin and Yang Sen, who were not far away, were already engaged in an intense on-site investigation. Yang Lin wore professional investigation gloves and held a strong flashlight, focusing the light on the inner wall of the sewer. "Yang Sen, look here." He carefully picked up a small piece of skin and flesh attached to the pipe wall with tweezers. "The edge of the wound is uneven and jagged. It is likely caused by a saw or other weapon." Yang Sen quickly raised his camera and took pictures of this detail from different angles. The flash kept flashing in the dim sewer.

Yang Sen then took out a portable ultraviolet lamp and slowly moved it over the wall of the well to illuminate it. Suddenly, several light blue fluorescent lights appeared, distributed in a splashing pattern. "It's blood. It has been cleaned but there are still traces left." Yang Sen said excitedly, "The murderer should want to destroy the evidence, but there are still omissions in a hurry." He immediately took out a cotton swab and took a sample of the blood. Yang Lin squatted down and carefully checked the location where the body fragments were found. "Judging from the distribution of the fragments and the direction of the blood splashing, this should not be the first scene." He pointed to the ground and said, "The body was cut into small pieces and then transported here to dump the body. And you see," he measured the distance between the fragments with a ruler, "these fragments are distributed more concentratedly, which means that the murderer was in a hurry when dumping the body, or he was familiar with the environment here and knew that this was a hidden dumping point."

Lu Chuan stood aside, listening to the two people's analysis with a frown on his face.

He began to make arrangements.

"So, Yang Lin and Yang Sen, the two of you will conduct a site survey around here to see if you can find other bodies the fastest. Expand the area, and the others will do some interviews."

The damp smell of mold and decay filled the narrow alley. Yang Lin and Yang Sen, wearing waterproof jumpsuits and gas masks, carefully stepped into the knee-deep sewage. The overhead construction lights cast a pale halo on the turbid water. Oil stains and debris floated in the sewage, and ripples appeared with the footsteps of the two.

"Watch your step, don't destroy any possible evidence." Yang Lin held a strong flashlight, and the beam swept back and forth across the well wall and the water surface. His voice sounded a little muffled through the gas mask.

Yang Sen carried the investigation box, took out the portable metal detector, turned on the switch, and the machine made a regular "beeping" sound. "The environment is too noisy, the metal detector may not be effective." Yang Sen frowned, "But I still have to try, in case the murder weapon or other metal evidence is underwater."

Suddenly, Yang Lin's flashlight stopped at a depression in the wall of the sewer pipe, where some dark red fragments were piled up. "I found something!" Yang Lin squatted down, and the sewage overflowed the hem of his waterproof suit. He carefully picked up a piece of tissue with tweezers, "Looking at the texture, it should be muscle tissue, and..." He held the sample up to the light, "There are obvious jagged cuts on the edge, which is consistent with the characteristics of reciprocating saw blade cutting."

Yang Sen quickly picked up the camera and took photos from different angles to collect evidence. "Ruler, put down a ruler," Yang Sen reminded. Yang Lin placed the ruler with scales next to the sample, and the flash light lit up again, accurately recording the size and state of the evidence.

"Extract the sample and mark the location." Yang Lin said, putting the tissue into a sealed evidence bag. "This is the third body fragment found today. Judging from the degree of healing and decay of the incision, the approximate time of death should be between 36 and 48 hours." (End of this chapter)
