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

Xiao Wu nodded repeatedly and quickly wrote down the key points in his notebook: "It turns out that there are so many factors to consider when determining the age of the deceased. They are so closely linked. It's really rigorous."

"What about the identity of the deceased?" Xiao Wu paused as he recorded. Zhang Kai took off his bloody gloves and grabbed a vernier caliper to measure his pubic bone: "About 28 years old, 165 cm, 52 kg." He pointed to the old injury on the clavicle, "The fracture five years ago healed neatly, and he should have received formal treatment at the time." Suddenly, his tweezers stopped at the base of the deceased's ring finger, "The wedding ring was violently torn off, and the skin lacerations were still bleeding - the murderer was afraid that we would find out his identity through the ring."

At the end of the autopsy, Xiao Wu looked at the body covered with white cloth, and the cold sweat on the back of his neck had already turned into ice. Zhang Kai put the last tissue sample into the centrifuge, and turned his head to instruct in the buzzing sound: "The skin scraps between the nails should be tested for DNA urgently, and the stomach contents should be analyzed for components. By the way," he kicked the evidence box at his feet, "Have you compared the fibers of the sculpture base with the clothes of the deceased? Don't miss any thread ends."

The autopsy continued, and Wang Shuai and Zhang Hui's investigation also continued.

The fluorescent screen in the monitoring room reflected the pale faces of Wang Shuai and Zhang Hui. More than 10 screens were flashing images from every corner of Beishan Park. Wang Shuai rubbed his sore eyes and fast-forwarded and paused the video of the early morning of October 15 for the third time. The only thing in the picture was the bleak autumn wind blowing fallen leaves across the empty trail.

"Brother Zhang, we've been watching for a whole day, and there's not a single suspicious person." Wang Shuai tugged at his collar, his neck numb from the air conditioning. "There are twelve surveillance cameras around here, but they didn't capture any vehicles coming in or out."

Zhang Hui placed the cold coffee cup heavily on the table. The porcelain cup collided with the metal tabletop with a dull sound. "Look more carefully. The murderer can't appear out of thin air." He pointed the laser pen at the lower right corner of the screen, where a crooked locust tree just blocked half of the intersection. "Mark this blind spot and retrieve the surveillance footage of the adjacent road section to see if there are any vehicles parked abnormally."

The two of them screened the video frame by frame, their eyes so sore that they could hardly open them. Wang Shuai suddenly sat up straight: "Wait, this person in the black coat is a bit strange." In the picture, a figure wrapped in a large black coat, wearing a baseball cap and a mask, wandered around the park for a few minutes before leaving. But the surveillance camera was too far away, and it was impossible to see the figure and face clearly.

"Zoom in, enhance the image quality." Zhang Hui leaned in front of the screen. But no matter how he processed it, the picture was still blurry, and he could only vaguely see a black bag in his hand. "Check the movement trajectory of this person, from the moment he appears to the moment he disappears, don't miss a single second."

However, after a day of tracking, the mysterious man completely disappeared from the surveillance blind spot after turning three intersections.

The verification and comparison of missing persons was also carried out that night.

In the computer room of the Criminal Investigation Brigade, the air conditioner emits a low roar. Wang Shuai's fingers tap rapidly on the keyboard, and the missing persons data on the screen refreshes like a waterfall. The notebook in front of him has been filled to page 27. There are sticky notes of various colors between the dense handwriting - yellow marks similar ages, green marks height ranges, and red circles valuable clues.

"Another round of comparison is over, and there is still no match." He rubbed his sore eyes and pushed the latest screening report to Zhang Hui. The blue light of the computer screen reflected on the tired faces of the two people. Next to the 1572 missing persons records, the red warning "No match" was still displayed under the photo of the deceased.

Zhang Hui slid the mouse and pulled up the autopsy report of the deceased: "Around 28 years old, height 165cm, weight 52kg, old fracture of right clavicle. These features should be very recognizable." He suddenly enlarged an X-ray film, "Contact various hospitals and check all cases of right clavicle fractures in the past ten years, focusing on women between 23 and 33 years old." Wang Shuai nodded and immediately dialed the phone numbers of 12 Class A hospitals in the city. When the mechanical waiting tone came from the receiver, he flipped through the photos of the deceased's clothes: "Brother Zhang, could this skirt be a custom-made one? Although the fabric is ordinary, the tailoring is very exquisite, and the cuffs are hand-stitched."

"It's possible." Zhang Hui tapped the photo with the tip of his pen. "Notify the Economic Investigation Team to check all high-end tailor shops and private custom studios in the city, especially those that have received orders for similar styles in the past three months." He paused and added, "By the way, send the photo of the deceased's earrings to the Jewelry Appraisal Center. Maybe we can find the source of the goods."

The call was finally connected, and Wang Shuai pulled himself together and said, "Hello, I'm from the Criminal Investigation Brigade. I'd like to ask you to help me with an inquiry." He had repeated this conversation hundreds of times in the past two days. After each call, he would carefully check the case data provided by the hospital and sort out the records that matched the age and injury. However, when these data were imported into the missing persons system for comparison, they were still disappointingly blank.

"Could it be someone from out of town?" Wang Shuai suddenly asked, "Should we contact the police in the surrounding cities?"

Zhang Hui pondered for a moment and called up the provincial missing persons database: "Expand the scope and focus on checking this province and neighboring provinces. Also, have the police station visit every household, especially rental houses and single apartments. Some people may have gone missing without anyone reporting the case."

I only slept for three hours that night.

Early the next morning.

Zhang Hui stared at the photos on the whiteboard: the deceased's off-white dress, the fabric was exquisite but without any brand logo; the silver high heels had slight wear on the heels, but the soles were unusually clean; the pearl earrings were ordinary in style and could be found everywhere in the market. "Have you sent the clothes for fiber analysis?"

"It's gone," Wang Shuai sighed. "The technical department said the fabric is common polyester fiber, and there are no signs of special processing. Even the mud on the skirt, the test results are consistent with the soil composition of Beishan Park, there is no way to locate the first scene."

The two visited all the businesses around the park. The pancake stand owner assured, "I open the stall at 4 o'clock every day, and I haven't seen anything wrong." The convenience store clerk flipped through the account book and shook his head, "There haven't been any strange customers recently, and I haven't seen anyone dragging large or small bags."

Night fell again, and Zhang Hui and Wang Shuai stood in front of the sculpture where the body was found. The autumn wind blew up the ginkgo leaves on the ground, making a rustling sound. "How did the murderer sneak the body of such a big person in here without anyone noticing?" Wang Shuai kicked away the stone at his feet, "It can't be that he carried it in in broad daylight while the tourists weren't paying attention, right?"

Zhang Hui squatted down and rubbed the gap of the sculpture base with his fingers: "There are traces of fresh prying here, which means that the murderer opened it beforehand. But the park is crowded during the day, and there are security patrols at night." He suddenly looked up and glanced at the surveillance camera not far away, "Wait, the security patrol route is fixed, could the murderer have committed the crime during the patrol breaks?"
