Era: Starting from the local police station

At this moment, Qin Weijun jogged over.

"How's the situation?"

Jiang Zhenghua slowed his pace and waited for him to approach.

"According to a woman, the bag was discarded by her husband around the time he was going to work the night shift at the Hongxing Machinery Factory."

"Okay, go and help maintain order."

Qin Weijun turned and left to help maintain order.

When Instructor Zhang noticed that Jiang Zhenghua hadn't followed, he turned around and waited for a while.

"Zhenghua, how's it going?"

"Uncle Zhang, the bag was discarded by the workers when they went to work the night shift. I remember my dad saying that their factory implemented a three-shift system this year in response to the higher-ups' call to double steel production."

"That's right, my cousin works at Hongxing Machinery Factory. His early shift is from 8 a.m. to 4 p.m., his middle shift is from 4 p.m. to midnight, and his night shift is from night to 8 a.m."

"Uncle Zhang, how long does it take to get to the Hongxing Machinery Factory from here?"

"It takes about 40 minutes to walk or about 20 minutes to cycle."

At this moment, two people jumped out of the jeep. The one in the lead was a middle-aged man wearing a dark blue cotton collared police officer uniform.

He is Jin Hong, the deputy director of the Dongcheng branch.

Director Qiao stopped and raised his hand in salute: "Welcome Deputy Director Jin to provide guidance on our work."

Deputy Director Jin raised his hand in return: "Hello, Director Qiao, I just came to take a look."

He nodded to Director Yu: "Director Yu is here too."

Director Yu saluted: "Good morning, Deputy Director Jin."

Deputy Director Jin waved his hand: "We're all old acquaintances, so don't be so polite."

After he finished speaking, he turned his gaze to Jiang Zhenghua.

Jiang Zhenghua stepped forward, saluted, and said, "Good morning, Deputy Director Jin. I am Jiang Zhenghua, Deputy Director of Taotiao Hutong Police Station."

Deputy Director Jin raised his hand in return: "Hello, Deputy Director Jiang."

He lowered his hand and said to the group, "Come on, let me introduce you to someone."

As he spoke, Deputy Director Jin strode toward the man and woman who jumped out of the car.

Upon reaching the two women, Deputy Director Jin pointed to the woman in her early twenties and said, "Let me introduce you. This is Comrade Fang Ya, a forensic medicine lecturer at the People's Public Security Academy. She came here specifically to support us."

He then introduced Fang Ya: "Comrade Fang, these two are Director Yu of Yu'er Hutong Police Station and Director Qiao of Taotiao Hutong Police Station."

Director Qiao immediately saluted: "Hello, Comrade Fang, thank you for coming to help."

Fang Ya, who is about 1.7 meters tall, has a petite figure and is wearing a neat summer police uniform. Her top is also made of white twill fabric, but unlike others, it has a large lapel Lenin style, a small pocket on the left chest, two slanted pockets with flaps on the lower hem, and four standard buttons on the front.

She wore a cloth belt with brass buckles, dark blue suit trousers, and a white brimless soft hat with a 2mm wide bright red piping along the brim and a dark green band.

Fang Ya raised her slender arm and saluted, saying, "Hello, Director Yu and Director Qiao."

She put her hand down and said to Deputy Director Jin, "Deputy Director Jin, I'll get ready and we'll go to the site for inspection now."

Deputy Director Jin nodded: "Thank you for your trouble."

Fang Ya instructed her assistant, "Prepare clothing and tools."

Deputy Director Jin turned around and asked, "Tell me about the situation at the scene?"

Director Qiao and Director Yu all turned their attention to Jiang Zhenghua.

Deputy Director Jin said to Jiang Zhenghua, "You tell us about the situation."

Jiang Zhenghua recounted the situation at the scene and what he had discovered.

After listening, Deputy Director Jin asked in surprise, "According to your description, the deceased was dumped here between 10 PM and 11:30 PM?"

Jiang Zhenghua nodded: "Based on the discarded waste and packaging bags, that's indeed the case. The deceased's time of death was probably around nine or ten o'clock."

Deputy Director Jin looked at Jiang Zhenghua with satisfaction: "Good, you are observant and have reasonable reasoning. I think you are very suitable for criminal investigation."

He turned to look at Chief Qiao and the others, and said in a deep voice, "To be honest, the branch office received a report that three murders occurred in the East District last night. All the people in the investigation department have been mobilized, and we are short-handed, which is why I came here personally. We couldn't even allocate any forensic doctors, so we had to ask for outside help."

Director Qiao tentatively asked, "So, about this case..."

Deputy Director Jin's expression turned serious: "We can only rely on you. I was a little worried at first, but after listening to Deputy Director Jiang's report, I believe you can shoulder this responsibility."

Director Qiao hesitated for a moment: "But what about manpower..."

Deputy Director Jin interrupted him: "It's not for your station to do it on its own. You and Director Yu will investigate together and form a special task force. You will be the team leader, and Director Yu and Deputy Director Jiang will be the deputy team leaders. As for personnel, Director Yu can provide a few people."

"We guarantee the mission will be completed."

The group immediately stood at attention and saluted.

Chief Yu said, "I'll have Chen Junsheng and two others come over to help. The command post will be located at your police station. As for the specific investigation, let Deputy Chief Jiang handle that."

Director Qiao nodded: "No problem."

The group then looked at Jiang Zhenghua.

He immediately replied, "I guarantee I will complete the mission."

Deputy Director Jin nodded: "You can rest assured and get to work. If there's a shortage of manpower, I'll coordinate with other police stations. Or if you need any other assistance, you can contact me directly."

Jiang Zhenghua thought for a moment and said, "Thank you for your support, Deputy Director Jin. We don't have many leads yet, but with the current manpower plus the members of the community security committee, we should have enough for the initial investigation."

"Alright. Then I wish you a speedy resolution to this case and bring justice to the deceased."

Deputy Director Jin nodded in satisfaction.

At this moment, Fang Ya, wearing a white lab coat and a mask, walked over carrying a suitcase: "Deputy Director Jin, how should we proceed?"

Deputy Director Jin said, "The investigation of this case is being directed by Deputy Director Jiang."

Fang Ya turned to look at Jiang Zhenghua and scrutinized him carefully.

Jiang Zhenghua pondered for a moment and said, "The environment here is quite complicated, with countless people coming and going. The footprints nearby are no longer of any value. First, determine the cause of death, and at the same time, take a photo of the deceased to see if we can identify them."

Fang Ya asked in surprise, "I brought a camera, that's not a problem. Time of death..."

Jiang Zhenghua recounted his previous speculations: "It would be even better if we could further confirm the timing."

Fang Ya shook her head: "You've already pinpointed it to this point; with current technology, it's difficult to be any more precise."

Deputy Director Jin chimed in, "Get me a cloth bag, let's go take a look together."

Fang Ya's assistant immediately opened the cloth bag, took out three strips of cloth, and then took out five masks, handing one to each person.

Dressed neatly, the group headed towards the garbage storage area.

After examining the deceased for a few moments, Deputy Director Jin nodded and said, "Your judgment is correct. The bruises on the deceased's forehead were not caused by a blow, but rather by him kowtowing and begging for mercy."

Fang Ya had already started taking pictures with a small camera, constantly adjusting her pose.
