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

Chen Yonggang stared at the gradually emerging bloody handprint, and his voice suddenly became unusually calm. "With the last kick, I kicked over the shoe box, and the Converse canvas shoes rolled to my feet - they were the couple's shoes we bought together last year." He bent down to pick up the virtual shoes, his knuckles turning white from the force.

Lu Chuan's laser pointer swept across the bloodstains on the wall: "Explain this angle." Chen Yonggang looked along the beam, his pupils suddenly contracted. "He raised his head and tried to bite off the strings," his Adam's apple rolled up and down, imitating the struggle of suffocation, "Blood spurted out of his nose and splashed on the wall like a weird flower. I counted, a total of seven drops, the largest one was more than a meter from the ground."

When he described using his knee to press against Chen Yongqiang's back, the police officers on the scene clearly saw that his knee was slightly bent, as if he was still bearing the weight. "When the strings were tightened for the last time," he suddenly choked up, "his hand loosened my wrist, but grabbed my little finger." He raised his left hand, and the little finger joint was obviously deformed. "I heard myself say 'I'm sorry, brother', but he couldn't hear it anymore."

The clouds outside the window suddenly blocked out the sun, and the shadow enveloped the entire room. Chen Yonggang's shadow twisted into a strange shape on the wall, gradually overlapping with the frozen death posture in the photos taken at the scene. When he finished his last word, he let out a dying sob in his throat, and his body slowly slid down the closet to the ground. The sound of the metal shackles hitting the floor was like the death knell of fate.

As a result, he was taken away by Wang Shuai and others.

"Go on, where is the body hidden?" Lu Chuan asked. Chen Yonggang mechanically walked to the bedside and bent down: "Under the bed, I later bought a freezer." His voice stopped abruptly, as if he no longer had the courage to continue. Yang Sen and the technicians immediately began to investigate under the bed. Although the body had been moved long ago, they were still able to extract key evidence through advanced criminal investigation technology.

The last stop was the Beiyang River where the bodies were dumped. The bleak autumn wind blew up the dead leaves on the river bank. Chen Yonggang stood by the river, looking at the slowly flowing water, his body trembling. "It was here that I dumped Li Xiaomin's body." He pointed to a reed bush. "It was cold and windy that night, and I watched her body being washed away by the river."

During the entire process of identifying the scene, Chen Yonggang was like a walking corpse. Every location and every detail of his confession was like rubbing salt into his own wounds. The police recorded the entire process on video, not missing any details. When the identification was over and Chen Yonggang was taken back to the police car, he suddenly looked back at the Beiyang River, with a trace of regret in his eyes, but it was too late.

The police car roared away, leaving behind only messy footprints on the river bank and the bloody truth that was revealed.

Less than three days had passed since the case was solved when Lu Chuan received a new report of the case.

The center directly transferred the alarm call to the Criminal Investigation Brigade. Some elderly people who were doing morning exercises in Beishan Park discovered that a sculpture of a flying goddess in the park was actually oozing blood.

The local police station has already checked the scene and found that it was not a prank and that the red liquid was not splashed with red paint. Some of the liquid was indeed blood, but it was not certain whether it was human blood. However, Lu Chuan and his men still rushed to the crime scene.

When three police cars flashed their lights and cut through the mist, the park entrance was already surrounded by tourists holding up their phones to take photos. Behind the cordon, a young auxiliary police officer was retching with a pale face, dark red liquid was flowing down from the sculpture's raised right arm, forming a small pool of blood on the base, and a faint stench of decay floated in the morning mist.

"Seal off the scene, no unauthorized persons allowed to approach!" Lu Chuan stepped forward quickly on fallen leaves, his black leather shoes stopping just beside the pool of blood. This three-meter-tall white marble sculpture presents a classical flying figure, but at this moment, the skirt, which should have been holy, is soaked in blood, and the solidified dark red is as piercing as a knife on the white stone. He squatted down, dipped his fingertips into the blood and twisted it - it was sticky and stringy, with the unique fishy sweetness of human tissue.

"Yang Sen, take a sample for inspection." Before Lu Chuan finished speaking, the technician wearing latex gloves began to scrape the blood. Yang Lin was lying on the ground, using a magnifying glass to observe the gap in the base: "The blood is seeping from the inside of the sculpture, and there are fresh prying marks on the bottom seam." He picked up a small piece of gray-white debris with tweezers, "It looks like plaster powder, someone has resealed the base." The roar of the crane broke the deadlock. When the sculpture was slowly lifted, screams broke out among the onlookers - a female corpse was curled up in the hollow base. The deceased was wearing a white dress, her long hair was wrapped in copper chains, and the hideous strangle marks and bruises on her neck showed her struggle before death. The surface of the corpse was covered with corpse spots, and her abdomen was bulging high due to the decaying gas. A few strands of long hair fell on the blood stains on the hem of the sculpture, as if it had merged with the stone.

"Death time is more than 48 hours." Forensic doctor Zhang Kai knelt in the fallen leaves and cut the skin of the deceased's wrist with a scalpel. The dark purple decayed vein network was clearly visible. "Death by strangulation. There is skin tissue residue between the fingernails." He held up the evidence bag. The bloody debris inside was gleaming under the investigation light. "The murderer and the deceased had a fierce fight."

Lu Chuan's eyes swept over the high heels on the deceased's feet - the heel of the right foot was broken, and the inside was stained with dark brown mud. "Wang Shuai, check the park surveillance, focusing on the abnormal situation late at night two days ago. Zhang Hui, visit the residents around and ask if they heard any unusual noises." He squatted down, and the flashlight beam illuminated the inside of the sculpture base. Several lines of blurred carvings were faintly visible in the dust. "Yang Lin, copy these marks and go back for analysis."

"Yes!"

The dusk was as dark as ink, dyeing Beishan Park a dark blue. Yang Sen raised his SLR camera, and the flash went off and on around the sculpture, capturing a detail with each flash.

"Pass me the scale." Yang Sen half-knelt beside the sculpture base, with the viewfinder of the SLR camera close to his eye socket. "When taking close-ups of physical evidence, the scale must be kept parallel to the target object, otherwise there will be errors in the later measurement."

Yang Lin quickly handed over the black ruler. He knew very well why he had to use this kind of scale with scale, because this professional scale was calibrated, the scale was accurate to millimeters, and the background color and scale had a clear contrast.

When the lens is focused on the pry marks, the numbers on the scale are still clearly visible.

At this time, Yang Sen pressed the shutter button, and the flash created a soft reflection on the surface of the white marble.

In addition, Yangcun always maintained a vertical shooting angle during the shooting.

This is to avoid perspective distortion.

Yang Sen compared the photos in the camera, some of which he deleted directly and some of which he kept. (End of this chapter)
