Ning Zhiheng examined Du Qian's neck carefully. It seemed that Zuo Gang had listened to him and had not let Du Qian bleed, leaving him with a complete corpse.
Moreover, they were experienced and did not use their fingers to pinch the airway, which would have left clear bruises and fingerprints on the neck. Fingerprints can reveal a lot of information, such as the fact that men's fingerprints are larger than women's, and that the fingerprints of fat and thin people are different. As a result, investigators can find many clues based on fingerprints. However, if someone strangles someone with their arm, it is much more difficult to find clues about the murderer!
“Looks like a seasoned pro,” Ning Zhiheng nodded and said. “Did Du Qian lose any valuables? Were his family members harmed?”
Ding Dahai quickly replied, "There was no loss of property. Nothing in the house was missing. Director Du's family was not harmed either. His wife has trouble sleeping, so the two of them sleep in separate rooms."
The killer was very familiar with Director Du's daily routine. He broke directly into the bedroom and murdered Director Du; he was a seasoned killer, leaving no clues whatsoever. The family heard nothing and only discovered Director Du's murder in the morning!
"Didn't the police headquarters send anyone to investigate this case?" Ning Zhiheng asked again.
"After I received the report this morning, I reported it to the General Bureau. Later, two officers came, took a look, and left, saying they needed to consult their superiors and told them to wait for further instructions!" Ding Dahai said.
Ning Zhiheng immediately knew that the two officers' superiors must know Du Qian's background and had sent a notice to the Military Intelligence Investigation Department to inform him. Ning Zhiheng snorted and said, "This is clearly a targeted revenge killing. Immediately question the family members and investigate who has had conflicts with Du Qian in the past few days."
Ning Zhiheng's intention was obvious. Soon, Wang Shucheng told the family about the incident two days ago when someone came to their door and argued with Du Qian. The family confirmed that the person was Pei Wenyao, a section chief from the Police Headquarters.
"You fool! Arrest Pei Wenyao immediately! I want people to know that anyone who dares to slap Ning's face will be skinned alive!" Ning Zhiheng said through gritted teeth.
Sun Jiacheng accepted the order and immediately led a team to arrest the person. Ding Dahai, who was standing to the side, looked at Ning Zhiheng's ashen face and couldn't help but feel secretly alarmed. It seemed that this team leader Ning was going to go on a killing spree and stir up a storm to establish his authority!
After ordering Wang Shucheng to finish the work, Ning Zhiheng led his team back to the Military Intelligence Investigation Department. He had a stern face, which made those around him afraid to say anything.
Once back in his office alone, Ning Zhiheng dropped his pretense and paced back and forth. He needed to project an aura that would let others know he was very angry and that the consequences would be severe.
He wanted to gradually put pressure on the police headquarters to force Han Xingping to come forward. If Han remained silent, he would simply go to his door. In short, he wanted to force the police headquarters to make concessions and take control of the Kangyuankou checkpoint.
The Kangyuankou Pass was of paramount importance. It was the only way for Nanjing to reach the rear, and most of the smuggled goods in Nanjing had to pass through here. It was a veritable treasure trove of lucrative goods.
Money was secondary to Ning Zhiheng; what mattered more was that it was a crucial element in the underground party organization's supply chain and absolutely could not fall into the hands of others.
As for who will take over Du Qian's control of this transportation line, Ning Zhiheng has limited talent at his disposal. He only has Liu Datong as his subordinate in the police department, so it seems he has no other choice.
Ning Zhiheng pondered for a long time, carefully considering his next move. He had to complete this task as soon as possible, as his time was limited and he needed to focus his energy on the Japanese spy organization.
At this moment, Sun Jiacheng knocked on the door and came in, reporting: "Team leader, Pei Wenyao has been brought back, but he was working at the police headquarters at the time, so it took some effort and caused a bit of a commotion. I estimate they will contact you soon!"
Ning Zhiheng nodded and said, "You did a good job. I just wanted to make a fuss. Once Pei Wenyao is arrested, Han Xingping behind him will definitely jump out. I want to see if this Han Xingping has the guts to steal food from my mouth!"
