On the day of my entry, I carried the wanted criminal report with one hand!

Chapter 198 is just a foreshadowing, the real action begins!
"By the way, I added him as a friend before!"

After finishing speaking, Zhang Sheng quickly turned on the phone, operated in it, and then pointed to the phone screen and said to Lin Yao:

"That's right, it's this guy, and his phone number is here too!"

"Ok."

Lin Yao nodded when he heard this, and leaned over to write down the phone number.

"Do you know anything else about Zheng Xiang?"

Afterwards, Lin Yao looked at him again and asked.

"This... is gone."

Zhang Sheng thought for a while, then shook his head and said.

"Okay, thank you."

"It's okay, it should be."

After Lin Yao and Cao Lin left Zhang Sheng, they questioned several employees, but they knew very little information.

Standing at the gate of the factory, Cao Lin handed Lin Yao a cigarette, and said:
"Brother Yao, our discovery this time is not small. This Zheng Xiang actually has a hobby of gambling."

"He borrowed money from this Zhang Sheng, and maybe he also borrowed money from others."

"Yes."

Lin Yao nodded and continued.

At this moment, Lin Yao's cell phone rang.

Lin Yao took it out and saw that it was Wang Ming from the Technical Squadron calling.

Only then did Lin Yao realize that he was asked to check the saliva on the mouth of the bottle just now.

"Hey, Brother Wang, how's it going? Has the result come out?"

So Lin Yao quickly answered the phone and asked inside.

"Come out, no saliva was detected on the mouth of this drink."

Wang Ming on the other end of the phone said in a deep voice.

"What? No saliva, have you checked carefully?"

Lin Yao immediately asked.

Wang Ming couldn't help laughing, and said:
"Xiao Lin, if you doubt this, you must doubt my ability to work. How can this be wrong!"

"Okay, sorry, Brother Wang, I see."

Lin Yao shook his head and smiled, and said to him.

Then, the two hung up the phone.

"Didn't you check your saliva? Brother Yao!"

After hanging up, Cao Lin couldn't wait to ask Lin Yao.

"Yes."

Lin Yao nodded, frowning and pondering.

"This is strange. Since this Zheng Xiang didn't drink, why did the murderer come to him?"

Cao Lin asked suspiciously.

Lin Yao said slowly:

"This further confirms our guess, that bottle of drink is not what Zheng wanted to buy to drink at all."

After listening to Lin Yao's words, Cao Lin didn't understand for a while, then he asked tentatively:

"Brother Yao, you mean that Zheng Xiang's case is also a hitchhiking murder case. Someone deliberately put drinks in his home to attract the murderer to kill him?"

"No, this drink should have been brought by the murderer."

Lin Yao directly shook his head and said,

"The murderer killed him first before putting down the drink. This is to give us an illusion that the murderer killed the deceased because he drank the drink."

"In that case... what is his purpose, why must we be associated with this drink, is his ultimate purpose of killing people really to make this drink factory go bankrupt?"

Cao Lin couldn't help asking in doubt.

Lin Yao looked at him and couldn't help laughing.

This kid is really cute.

"I've said this to this extent, don't you understand? He tied death and drinks tightly."

"In this way, we will focus on the beverage and ignore other aspects of the investigation."

"And when predicting the next victim, he will only use who bought the drink as a clue, but can't find the person he really wants to kill."

So Lin Yao patiently explained to him.

Hearing this, Cao Lin finally nodded, with a sudden realization:

"Oh! I understand what you said! In other words, the murderer actually has a grudge against Zheng Xiang. He just wanted to kill Zheng Xiang. It has nothing to do with the drink, and Zheng Xiang didn't buy the drink either."

"Yes, in the first two cases, the migrant workers and the woman who jogged in the morning had saliva detected on the mouth of their beverage bottles, and they indeed drank the beverages."

Lin Yao nodded and continued.

"But the two of them are just a foreshadowing for the murderer, in order to create the illusion that if you drink a drink, you will die."

"Next, he will start killing the targets he really wants to kill."

"And Zheng Xiang is the first one, but we don't know if he is the last one!"

After listening to Lin Yao's analysis, Cao Lin said angrily:

"If this is the case, this murderer is simply insane! Killing so many innocent lives!"

"So now we have to start with Zheng Xiang's interpersonal relationship and investigate clues."

Lin Yao continued,

"We have to be quick, because we don't know if and when the murderer will do it!"

"Well, let's go find his poker buddies! He loves gambling so much, maybe he offended someone in the casino."

Cao Lin nodded repeatedly.

Afterwards, Lin Yao directly took out his mobile phone and called the phone number that Zhang Sheng asked for.

"Hello? Hello, is this Liu Chengfeng?"

"Yes, who are you?"

"I'm from the Municipal Criminal Police Team. I need to ask you to find out the situation. Where are you now?"

Lin Yao said directly to the other end of the phone.

"Interpol? You... aren't a liar, are you?"

asked hesitantly on the phone.

"No, please rest assured."

After Lin Yao finished speaking, he felt a little pale and powerless.

No liar will admit that he is a liar.
"Oh, as long as it's not a liar, Comrade Police, I'm at home, Huayuan District, Building 1, Room 303."

Ok
Lin Yao agreed, and then hung up the phone.

Afterwards, Lin Yao and the two came directly to the door of his house and knocked on the door.

After Liu Chengfeng inside saw Lin Yao and the others, he let them in at a loss.

"Comrade policeman, what did I do? Did someone sue me and say I owed money? Or was it because of my PC last month?"

Before Lin Yao could speak, Liu Chengfeng spoke by himself.

Lin Yao and Cao Lin looked at each other and shook their heads helplessly.

"No, we are here now to ask you to find out about Zheng Xiang's situation. Please cooperate with us and tell us all the information you know."

Lin Yao stared at him seriously and said.

"Zheng want?"

Liu Chengfeng was taken aback for a moment, then breathed a sigh of relief,

"Oh, it turns out that you guys are investigating Zheng's thoughts, you scared me!"

"Well, first ask him about his affairs, and then go to the police station and explain about your PC last month after asking him about his affairs."

Lin Yao nodded, looked at him and said.

"Ah no, don't!"

Liu Chengfeng waved his hands again and again.

"Okay, let's get down to business, how long have you known Zheng Xiang?"

"Well, it's been more than a year."

Liu Chengfeng thought about it and said to Lin Yao.

"How did you meet?"

"I met him playing cards, a friend of a friend."

"Do you often play cards together?"

"Yes, but I haven't seen him in a while."

Liu Chengfeng looked at Lin Yao and said, then he couldn't help but asked in doubt:
"Did Zheng think he did something wrong? I usually look at him very honestly."

"How did you get all of you here?"

"Cough! Please be careful with your words."

Lin Yao stared at him and reminded.

"Ah, sorry, Comrade Police, slip of the tongue! Do you have anything else to ask? As long as I know, I will tell you everything!"

Liu Chengfeng said with a smile.

"Let me ask you, has he offended anyone, or has any enemies?"

Lin Yao continued to stare at him and asked.

"Enemies? There shouldn't be any, right? Zheng Xiang is usually quite honest and easy-going, and has never had any grudges with anyone."

Liu Chengfeng shook his head and said, then he couldn't help asking Lin Yao:

"Comrade police, can you tell me what happened to Zheng Xiang first, this will also help me provide you with information."

"You are just asking me, I don't even have a direction to think."

Lin Yao stared at him fiercely, then said slowly:

"He was killed and stabbed in the chest."

"what?!"

Liu Chengfeng suddenly opened his eyes wide in horror, and asked in disbelief:
"He's dead? Comrade policeman, are you kidding me?"

"Do you think I came here to make fun of you?"

Lin Yao stared at him and said in a deep voice.

"Excuse me, Comrade Police, I'm just so shocked!"

Liu Chengfeng stared at the front with dull eyes, shook his head repeatedly and said,
"Oh, I see! Is it the recent drink serial killer? Now because of that incident, I dare not go out for two days!"

"Hiss shouldn't be! Why would Zheng think he would drink that kind of drink? It doesn't suit his taste!"

Lin Yao waited for Liu Chengfeng to finish speaking, and then asked:

"Remember again, whether he has any grudges with anyone, think about it!"

"Don't worry, let me think about it. Oh, I remembered. In the first half of the year, he seemed to be playing cards with us, Old Xiao, who had a quarrel! At that time, the two of them had a quarrel because of something in the game. I was blocked by other people, and then I was fine."

Liu Chengfeng tilted his head to recall,

"Could it be that after this incident, Lao Xiao has been brooding about it all the time, and then he ordered an assassin to kill Zheng Xiang? It's not a trivial matter, is it?"

"Anything else?"

Lin Yao pondered for a while, but also thought it was impossible.

After all, it was just a small conflict over playing cards, and it wasn't to the point of killing people.

"I really don't know the rest. I don't know who he had conflicts with."

Liu Chengfeng shook his head directly.

"Then do you know who he owes money to?"

Immediately afterwards, Lin Yao asked him again.

"Well, Comrade Police, if you can ask this question, it means that you have already investigated it."

After listening to Lin Yao's words, Liu Chengfeng nodded immediately and said,
"He was unlucky for a period of time. He did lose a lot of money and borrowed a lot from others."

"How much money did you lose?"

Lin Yao continued to ask.

"this."

Liu Chengfeng hesitated.

Because this question involved gambling money, he didn't want to answer it.

"Please tell the truth, otherwise you will be responsible for any problems that arise."

Lin Yao stared at him closely and said sharply.

"He lost about 60 yuan. At the beginning, he couldn't come up with so much money. He owed it first, and then he should have borrowed money. Anyway, he filled it up."

Liu Chengfeng had no choice but to tell the truth.

"More than 60 million?!"

Cao Lin on the side couldn't help clicking his tongue.

He didn't expect them to play so big!

"Do you know who he borrowed the money from?"

Lin Yao didn't say anything else, but continued to ask.

"I don't know that."

Liu Chengfeng shook his head.

Afterwards, Lin Yao asked him a few more questions, seeing that he couldn't get any useful information from him, so he went out first.

After leaving Liu Chengfeng's house, Cao Lin couldn't help but said to Lin Yao in surprise:

"I can't see, this Zheng Xiang is really not that simple, and it involves so much gambling money!"

"I think the murderer should have something to do with his gambling!"

Lin Yao also frowned and nodded slightly:

"Well, judging from the current situation, this is the most suspicious thing."

"Let's go, let's be in the team first, and I will report to Team Leader Fan."

"Okay, let's go."

After the two returned, Fan Jun was discussing the case in their office.

Lin Yao opened the door and came in, and everyone immediately turned their attention to him.

"How is it? Kobayashi, did you find anything?"

Han Bin asked immediately.

Lin Yao looked around the people in the office, and then said:
"Have Team Leader Fan told you all about the previous situation?"

"Well, I said it."

Everyone nodded.

"Now I have another major discovery here, that is, no saliva was extracted from the mouth of Zheng Xiang's drink bottle."

Lin Yao was also unambiguous and said directly.

Sure enough, after hearing this situation, everyone immediately started discussing:

"No saliva? Why did the murderer, Zheng Xiang, come to the door without drinking?"

"That's right! As I said before, in fact, the murderer doesn't know who drinks the drink at all, but if he sees who buys this drink, he may come to kill him!"

"No, no, I think...whether you bought a drink or drank it is not the key to the murder. The drink is more like a form."

Han Bin shook his head suddenly and analyzed.

"Yes, I agree with Brother Han!"

When Lin Yao heard what Han Bin said, he immediately agreed.

Everyone immediately turned their attention to Lin Yao.

Lin Yao continued:

"In the first two cases, there was the victim's saliva on the mouth of the bottle, but in Zheng Xiang's case, there was no saliva on the mouth of the bottle, which means that Zheng Xiang did not drink the drink."

"So based on my analysis, Zheng thought, it was the person the murderer wanted to kill, and it had nothing to do with the drink."

"The beverages in the first two cases were also the foreshadowing for the murderer to create a serial murder case with beverages."

"After the case is laid out, all of our attention will be on whether to drink the drink with the pattern, and the motive of the murderer itself will be ignored."

"Every time this happens in the future, we will attribute it to the deceased drinking the drink."

"It can be said that the murderer got a ride on his own!"

As soon as Lin Yao said this, there was an uproar at the scene.

After a few seconds, everyone agreed!

"Yeah, after Xiaolin said that, I really want to understand!"

"He kept everything secret, thinking that with the foreshadowing of the first two cases, we would be played around by him."

"But he forgot that we check to see if the deceased drank the drink."
