Serious Crime Unit 1

Chapter 1075
When Jiang Yiming and Zhou Ting appeared in front of Feng Lingcheng, they immediately identified Feng Lingcheng as the suspect who purchased levonorgestrel tablets.After he saw the two of them, he was stunned for a moment, and a huge pressure pressed on his heart, making him confused.

I don’t know who told the company’s manager that the police were looking for Feng Lingcheng.The manager came to the office area and briefly asked Jiang Yiming. Jiang Yiming explained to him. After he understood the situation, he invited them to the lounge because the lounge was convenient for questioning.

The manager made three cups of tea and placed them on the coffee table next to the sofa, and then went out. Before leaving, he told Feng Lingcheng to cooperate with the police's inquiries. Feng Lingcheng nodded and sat down opposite Jiang Yiming and Zhou Ting.There was a trace of imperceptible anxiety and fear in his eyes, which was noticed by Jiang Yiming.

"Is your name Feng Lingcheng?"

"Yeah." He replied softly, his mind running at high speed, thinking about how to deal with them.

"Do you know Ye Qianqian?"

"I know her. She is my fellow countryman. What's wrong with her?"

"You asked knowingly. She died and was murdered."

"Oh, what a shame, she died so young." He wasn't shocked.

"Do you know where Ye Qianqian lives?"

"I don't know, my relationship with her is just average."

"Don't you know that lying to the police will have serious consequences?" Jiang Yiming looked at him coldly. He did not dare to look at Jiang Yiming, lowered his head, and stared at the floor.

"Have you been to the drug store recently to buy levonorgestrel tablets?"

"No, I'm not a woman, why should I buy birth control pills?"

"You don't want to cooperate with our work at all. It seems that we have to change the conversation somewhere. Come on, please come with me to the Municipal Bureau's Criminal Police Team and cooperate with our investigation." Jiang Yiming said seriously, then stood up from the sofa and walked out.

Feng Lingcheng became even more anxious. He didn't know whether to go with them or not. However, he had no right to refuse the police's verbal summons. He had to follow Jiang Yiming out of the lounge, while Zhou Ting followed Feng Lingcheng to prevent him from escaping.

After arriving at the criminal police team, Wu Jiang extracted Feng Lingcheng's shoe prints and compared them. The comparison results were exactly the same as the shoe prints during the second investigation of the scene.Xiao Ke extracted his saliva and gave it to Luo Jin for DNA testing to see if the sweat stains left on Ye Qianqian's computer desk were his.

Jiang Yiming put him in the detention room, intending to leave him alone and put him under psychological pressure, which would help with the interrogation.Judging from the current situation, it can only be proved that he purchased levonorgestrel tablets and entered the scene to take something away. There is no evidence to prove that he was the murderer who replaced the levonorgestrel tablets.It's possible that he was the one who bought the levonorgestrel tablets for the killer.

Of course, judging from the current evidence, he can be detained and interrogated.The difficulty of this case is that the murderer did not leave fingerprints or biological samples on the levonorgestrel tablets. However, if there is more evidence to prove that Feng Lingcheng committed the murder, he can be convicted.

The motive for murder is also very important. If there is no motive for murder, but there is only partial evidence and no complete chain of evidence is formed, the suspect cannot be convicted.

Jiang Yiming didn't understand why Feng Lingcheng wanted to kill Ye Qianqian.At this time, he remembered Zeng Chenlu. She, Feng Lingcheng and Ye Qianqian were from the same hometown. Maybe Zeng Chenlu knew about Feng Lingcheng and Ye Qianqian's situation.Jiang Yiming took out his mobile phone and dialed Zeng Chenlu's number. The call went through: "Hello, Xiao Zeng."

"Hello, Captain Jiang, what do you want from me?" Her voice is still so sweet. She is born to be a receptionist. Many people will be fascinated by her voice.

"Do you know Feng Lingcheng? He is also from Guigang."

"Of course I know him...what's wrong with him?"

"He is the suspect of Ye Qianqian's murder. We want to know, what is the relationship between him and Ye Qianqian?" "This is a bit long, so I'll make it short. He knew Ye Qianqian when he was in school in Guigang, and they both He was an alumnus. Later, Feng Lingcheng was admitted to university and worked in Yangtze City after graduation. Ye Qianqian dropped out of school and reunited with Feng Lingcheng soon after arriving in Yangtze City.

"Feng Lingcheng didn't expect that Ye Qianqian would turn out to be a beautiful woman, and he soon fell in love with Ye Qianqian. Ye Qianqian also liked the tall and handsome Feng Lingcheng. Their relationship quickly heated up and they became an inseparable couple. Like me, Qianqian worked as a hostess at Huarong Restaurant, but for some reason, Ye Qianqian felt that being a hostess was too hard and the income was low, so she quit her job and worked as an escort girl in a nightclub.

"This made Feng Lingcheng extremely disgusted. The two often quarreled. As a result, Ye Qianqian proposed breaking up with him. Feng Lingcheng firmly disagreed and told her not to go to work. He would take care of her for the rest of her life. However, Ye Qianqian was unwilling and left Feng Lingcheng resolutely. . Feng Lingcheng couldn't keep her heart, so he had to treat her as a friend. That's probably what happened. They have broken up for more than two years. If you didn't ask, I would have forgotten about it. "

"Did Feng Lingcheng spend a lot of money on Ye Qianqian?"

"Well, it's not much to say, but Feng Lingcheng is as good to Ye Qianqian as he is to his wife. He gives her all his salary cards for safekeeping, and she can spend as much as she wants. What exactly did Ye Qianqian spend? I’m not sure how much Feng Lingcheng earns, I think it’s not much. After all, Feng Lingcheng’s monthly salary is not very high, only about 1 yuan. However, I heard that his bonus is relatively high, and there is commission for the games he develops.”

"I understand, thank you!" After Jiang Yiming hung up the phone, he pondered: Feng Lingcheng had a motive for murder because Ye Qianqian was a money-worshiping girl. She only had money in her eyes and no feelings. She was also capricious and flirtatious. Such a woman would It aroused Feng Lingcheng's strong hatred.

If Feng Lingcheng is the murderer of Ye Qianqian, how can we find the evidence?At this time, Lu Yingying walked into Jiang Yiming's office, and Jiang Yiming told her his thoughts.

She thought for a moment and said: "If Ye Qianqian was killed by him, then he would definitely buy potassium cyanide, and an IT guy like him would most likely choose to buy potassium cyanide on the dark web. Therefore, It will leave traces on his computer or mobile phone, as well as on his bank account, WeChat Pay, Alipay and other payment platforms. Even if the record is deleted by him, I can still restore it to its original state."

"You mean: As long as we get a search warrant and search his computer, mobile phone, home, and work, it is possible to find evidence of his crime."

"Yes, I want to tell you good news. Ye Qianqian's suicide note was sent from a computer to Ye Qianqian's computer version of WeChat, and then the content of the suicide note was copied to Ye Qianqian's document. The person who sent the suicide note The IP address is that of Tianma Time Network Company, and the corresponding computer is the computer used by Feng Lingcheng."

"Great. I'll go to Bureau Fang to get a search warrant. Let's search Feng Lingcheng's residence and company together." Jiang Yiming walked out of the office and walked to Fang Lihua's office. After arriving at Fang Lihua's office, Jiang Yiming explained the situation to him, After Fang Lihua listened, he took out a search warrant from the drawer, filled it out with a pen and handed it to Jiang Yiming.

Jiang Yiming came to the office area and ordered Wu Jiang, Xiao Ke and Wen Xiaorou to search Feng Lingcheng's residence. He, Zhou Ting and Lu Yingying went to Tianma Time Network Company to search Feng Lingcheng's computer.In order to speed up work efficiency, they took Feng Lingcheng away with them.

Jiang Yiming asked Feng Lingcheng to hand over the key to his home, otherwise, they would break in. Feng Lingcheng had no choice but to hand over the key. After Jiang Yiming got the key, he handed it to Wu Jiang.

They took Feng Lingcheng to Tianma Time Network Company, came to his computer, and asked him to turn on the computer, but he could only do it.After starting the computer, he entered his password. After entering the desktop, Lu Yingying sat down and carefully checked the web pages he had browsed, but found nothing suspicious.

Lu Yingying thought he might have cleared his browsing traces, so she used software to restore all the web pages he had browsed to their original state, and started checking them one by one. It turned out that he had purchased 2 grams of potassium cyanide on a foreign pornographic website.The payment was made using Feng Lingcheng’s Alipay.A total of 3000 yuan was spent, which was much more than the market price.

This made Lu Yingying excited. With this purchase record, she could form an evidence chain with the surveillance video of his purchase of levonorgestrel tablets, shoe prints, sweat stains and other physical evidence left at the scene.

Wu Jiang and Xiao Ke found some fine powder on Feng Lingcheng's computer desk. Wu Jiang believed that Feng Lingcheng might have left the powder when he hollowed out the levonorgestrel tablets with a sharp instrument. He also found suspected cyanide on the table. The potassium residue may have been accidentally spilled when Feng Lingcheng used a needle to inject potassium cyanide into the levonorgestrel tablets.

Wu Jiang gave these two substances to Luo Jin for testing, and the results came out quickly. The powder was indeed levonorgestrel tablets, and the other extract was potassium cyanide.With this evidence, coupled with the surveillance video of Feng Lingcheng purchasing levonorgestrel tablets and the record of purchasing potassium cyanide, as well as the shoe prints he left at the scene, a complete chain of evidence has been formed.

Jiang Yiming, Wu Jiang and Lu Yingying participated in the interrogation of Feng Lingcheng.

"Feng Lingcheng, why did you kill Ye Qianqian?" Jiang Yiming asked.

"I didn't kill her." His voice was very soft.
