Liang Damin told Shao Jian that Niu Dajiang's son, Niu Jiayu, had gone to Henan on official business and had not been contacted yet; everything was pending his instructions.

Shao Jian thought for a moment and said:

"Old Liang, have someone contact Niu Jiayu and tell him to come back immediately. Also, contact other relatives, like his daughter who lives in the nearby Yushan Township. On the one hand, their father has passed away, and the relatives should be notified. On the other hand, we may need to ask them some questions, mainly about how Niu Dajiang and Liu Xianghai knew each other."

Liang Damin was a veteran head of the security department, so he naturally understood what Shao Jian meant.

If Niu Dajiang provided Liu Xianghai with factory uniforms and meal tickets, then he must have already been in contact with Liu Xianghai and inquired about the situation from his children, which is a normal procedure in the investigation.

"Yes, Director Shao, I understand, I know how to arrange it."

"No one has been in the other rooms, right?"

"No, I had two security guards watching over the place, and I didn't let anyone else in."

"Then you go arrange the work, Dinghuai and I will go check the bedroom and rooms."

As he spoke, Shao Jian turned to look at Wu Dinghuai:

"Dinghuai, let's go. Let's search the deceased's bedroom or other rooms to see if we can find any useful clues."

The two people went into the living room and bedroom, and then closed the doors.

While Shao Jian and Wu Dinghuai were searching for clues, the ambulance dispatched by the infirmary arrived downstairs quickly, and several security personnel also went upstairs.

Liang Damin immediately arranged for people to lower Niu Dajiang's body down from the rope, carry it downstairs, put it in an ambulance, and drive it directly to the factory's medical clinic.

Previously, Shao Jian and Wu Dinghuai had entered Niu Dajiang's bedroom and turned on the light switch.

They first checked Niu Dajiang's bedroom. After searching for a while, they found only a dozen or so cigarette butts in the ashtray, indicating that Niu Dajiang had gone through a fierce internal struggle before his death, but they found no other useful clues.

Niu Dajiang lives in an apartment. He was not eligible for an apartment when he was single. When his son came to work, they lived in separate single dormitories. However, after his son Niu Jiayu married Wang Guihua from a nearby village, the factory reluctantly allocated them a small two-bedroom apartment, less than 60 square meters, with each room only a dozen square meters. It was the same type and size as the apartment allocated to Wei Hong's family.

After inspecting Niu Dajiang's bedroom, Shao Jian and Wu Dinghuai went to the bedroom of Niu Dajiang's son, Niu Jiayu.

Upon opening the door, a kraft paper envelope was seen placed on Niu Jiayu's bedroom bed.

Shao Jian and Wu Dinghuai both knew what was going on. They immediately realized that this letter was probably a message left by Niu Dajiang for his son before he died, or perhaps "last words" would be a more accurate description.

The two police officers, one old and one young, exchanged a glance.

"Dinghuai, open it and take a look."

Wu Dinghuai hummed in agreement, reached out and picked up the letter from the bed, then pulled it out.

Instead of looking at it himself first, he handed it to Shao Jian beside him and then leaned closer to look at it.

After reading it, Shao Jian handed it to Wu Dinghuai.

“Dinghuai, our deduction was correct. Liu Xianghai is indeed a Kuomintang agent who has been hiding all this time. This old guy has been hiding under the guise of a barber. Keep this letter safe for now, take a picture of it when you get back, and show it to the deceased’s children so they know the cause of their father’s death.”

While Shao Jian was quickly reading the contents of the letter, Wu Dinghuai, who was standing to the side, had already scanned it once and grasped all the contents.

After agreeing, he folded the brown envelope in half and put it in the pocket of his police uniform.

The two then checked other areas, including a table and three drawers, and two large red wardrobes, but found no useful clues or information.

When they came out, Liang Damin told Shao Jian that the body of the deceased Niu Dajiang had been sent to the morgue of the medical clinic, and that someone had been asked to notify Niu Jiayu to hurry back from Henan by car. In addition, two security personnel had obtained a car from the factory and were going to Yushan Township to pick up Niu Dajiang's two daughters, Niu Jiazhen and Niu Jiarong, and bring them back to the factory.

After hearing this, Shao Jian looked at Liang Damin:

"Did you tell their children that Niu Dajiang hanged himself at home?"

Liang Damin shook his head in denial.

"No, I had someone inform their two daughters that their father, Niu Dajiang, had passed away at home. I asked the security personnel to keep the specific cause of death a secret for the time being. As for Niu Jiayu, I didn't inform him of Niu Dajiang's death. Instead, I told him to return to the factory immediately because there was something very urgent."

Shao Jian nodded in satisfaction.

"Old Liang, this is the best way to inform them. Niu Jiayu will be back at the factory from Henan in about two days. By the way, once Niu Dajiang's two daughters arrive at the factory, we should first arrange for them to stay at the guesthouse. We need to get some information from them first."

Liang Damin immediately promised to cooperate, but then put forward his own ideas.

"Director Shao, I understand. Shouldn't we let them see Niu Dajiang's body first?"

Shao Jian nodded in agreement.

"Okay, Wei Hong has already notified us. We'll have her perform an autopsy on Niu Dajiang in a bit. It might take the city's forensic doctors at least two or three hours to get here."

The three people walked out of Niu Dajiang's house and down the stairs, talking as they went.

Just as the group was about to jump into the jeep, Qiushou jogged towards them.

Qiu Shou ran up to Shao Jian, grabbed his arm, and asked in a questioning tone:

"Uncle Policeman, Uncle Policeman, can I ask you a question?"
