"By the way, I added his friend before!"

After finishing speaking, Zhang Sheng hurriedly opened the mobile phone, operated in it, and then pointed to the mobile phone screen and said to Lin Yao:

"That's right, it's this person, and his mobile phone number is here!"

"Okay."

When Lin Yao heard this, he nodded, leaned over and wrote down his mobile phone number.

"Do you know anything else about Zheng Xiang?"

Then, Lin Yao looked at him again and asked.

"This.... Not really. ”

Zhang Sheng thought for a moment, 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 then 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, maybe he also borrowed money from others."

"That's right."

Lin Yao nodded, and then continued.

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

Lin Yao took it out and saw that it was Wang Ming from the technical squadron who called.

Only then did Lin Yao think of asking him to check the saliva on the mouth of the bottle just now.

"Hey, Brother Wang, how's it going? Are the results out? ”

So Lin Yao hurriedly answered the phone and asked inside.

"Came 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? Without saliva, have you checked carefully? ”

Lin Yao immediately asked.

Wang Ming couldn't help but laugh and said:

"Xiaolin, you are suspicious of this, how much do you doubt my ability to work, how can this be wrong!"

"Okay, I'm sorry, Brother Wang, I know."

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

Then the two hung up.

"Didn't check the 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 the drink, why did the murderer come to the door to look for him?"

Cao Lin asked suspiciously.

Lin Yao slowly spoke:

"This further confirms our suspicion that the bottle of drink was not what Zheng wanted to buy and drink at all."

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

"Brother Yao, do you mean that Zheng Xiang's case is also a hitchhiker murder, and someone deliberately put drinks in his house to attract murderers to kill him?"

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

Lin Yao shook his head directly and said,

"The murderer killed him first and then put down the drink, which is to give us the illusion that the murderer was killed because the deceased drank the drink."

"In that case...... What was his purpose, why did he have to associate us with this drink, and was the ultimate goal of his murder really to shut down the beverage factory? ”

Cao Lin couldn't help but ask suspiciously.

Lin Yao looked at him and couldn't help but smile.

This kid is really cute.

"I've gotten it all to this extent, don't you understand? He tied death tightly to drink. ”

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

"And when predicting the next victim, he will only use the clue of who bought the drink, and not find out who he really wants to kill."

So Lin Yao patiently explained to him.

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

"Oh! I get what you say! In other words, this murderer actually has a grudge against Zheng Xiang, he just wants to kill Zheng Xiang, and it has nothing to do with drinks, and Zheng Xiang did not buy drinks. ”

"Yes, the migrant worker and the woman who went for a morning jog in the first two cases did drink with saliva detected in the mouth of their drink bottles, and they did drink the drink."

Lin Yao nodded and continued.

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

"Next, he's going to start killing the target he's really trying to kill."

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

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

"If that's the case, this murderer is simply mad! Killing so many innocent lives! ”

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

Lin Yao continued,

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

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

Cao Lin nodded again and again.

Then, Lin Yao directly took out his mobile phone and called the phone number that asked Zhang Sheng just now.

"Hello? Hello, is it Liu Chengfeng? ”

"Yes, who are you?"

"I'm from the Municipal Criminal Police Team, I need to ask you about the situation, where are you now?"

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

"Detective? You..... Not a liar, right? ”

The other end of the phone asked hesitantly.

"No, don't worry."

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

How can a scammer take the initiative to admit that he is a liar......

"Oh, it's not a liar, comrade policeman, I'm at home, Garden Community, Building 1, 303."

All right.....

Lin Yao agreed, and then hung up the phone.

Then, Lin Yao and the others came directly to his door and knocked on the door.

After Liu Chengfeng inside saw Lin Yao and the two of them, he was at a loss to let them in.

"Comrade policeman, what did I do? Did someone sue me and say I owe money? Or is it because of what happened to my PC last month? ”

Without waiting for Lin Yao to speak, Liu Chengfeng spoke by himself.

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

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

Lin Yao stared at him with a serious face and said.

"Zheng Xiang?"

Liu Chengfeng was slightly stunned, and then suddenly breathed a sigh of relief,

"Ao, it turns out that you are investigating Zheng Xiang's matter, scare me!"

"Well, ask him about it first, and after asking him about him, you can go to the police station and explain what happened to your PC last month."

Lin Yao nodded, looked at him and said.

"Ahh No, don't! ”

Liu Chengfeng waved his hand again and again.

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

"Hmm.... It's been more than a year. ”

Liu Chengfeng thought about it and said to Lin Yao.

"How did you meet?"

"Friends of friends."

"Do you play together a lot?"

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

Liu Chengfeng looked at Lin Yao and said, and then couldn't help but ask suspiciously:

"Did Zheng think he had done something? I usually look at him quite honestly....."

"Why did you get all of you?"

"Ahem! Please pay attention to the wording. ”

Lin Yao stared at him with his eyes and reminded.

"Ah, I'm sorry, comrade policeman, slip of the tongue! Is there anything else you need to ask? As long as I know, I'll tell you everything! ”

Liu Chengfeng said with a smile.

"I ask you, has he offended anyone, or has he had any enemies?"

Lin Yao continued to stare at him and asked.

"Enemies? This... There shouldn't be, Zheng Xiang is usually quite honest, easy-going, and has never had a grudge against anyone. ”

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

"Comrade policeman, can you tell me what happened to Zheng Xiang first, so that it will also help me provide you with information."

"You just ask me like this, and I don't have a direction to think."

Lin Yao's fierce eyes stared at him tightly, and then said slowly:

"He was killed and stabbed in the chest."

"What?!"

Liu Chengfeng's eyes suddenly widened in horror, and he asked in disbelief:

"He.... He's dead? Comrade policeman, you... You're not kidding, are you? ”

"Do you think I'm here to joke with you?"

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

"I'm sorry, comrade policeman, I just feel so shocked!"

Liu Chengfeng's eyes were glazed, staring ahead, shaking his head again and again and said,

"Oh, I see! Isn't it the recent serial murderer of what drink? Now because of that incident, I don't dare to go out for the past two days! ”

"Shhhhh It shouldn't be! Zheng wondered how he could have drunk that drink? Not to his taste! ”

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

"You have a good memory, whether he has a grudge against anyone, think about it!"

"Don't worry, let me think about it..... Ao, I remember, in the first half of the year, he seemed to be playing cards with us Lao Xiao was awkward! At that time, the two quarreled because of the card game, and were stopped by others, and then it was fine. ”

Liu Chengfeng tilted his head and recalled,

"Could it be that after this incident, Lao Xiao has been haunted by it, and then killed Zheng Xiang with a killer? It's not a trivial matter....."

"Anything else?"

Lin Yao pondered for a while, and also felt that it was impossible.

After all, it's just a little conflict because of playing cards, and it's not to the point of killing people.

"I really don't know the rest, I don't know who he had a conflict with."

Liu Chengfeng shook his head directly.

"Do you know who he owes money then?"

Immediately after, Lin Yao asked him again.

"Hmm... Comrade policeman, if you can ask this, it means that you have already investigated. ”

After listening to Lin Yao's words, Liu Chengfeng immediately nodded and said,

"He was unlucky for a while, and he did lose a lot of money, and he borrowed a lot from others."

"How much money did you lose?"

Lin Yao continued to ask.

"This...."

Liu Chengfeng hesitated.

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

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

Lin Yao stared at him tightly and said sharply.

"This ..... He lost about 600,000 yuan, and he couldn't take out so much money at first, so he owed it first, and then he should have borrowed money, and he filled it all in anyway. ”

Liu Chengfeng had to explain truthfully.

"More than 600,000?!"

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

He didn't expect them to play so big!

"Do you know who he borrowed from?"

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

"I don't know about that."

Liu Chengfeng shook his head.

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

After coming out of Liu Chengfeng's house, Cao Lin couldn't help but say to Lin Yao with some surprise:

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

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

Lin Yao also frowned and nodded slightly:

"Well, that's the most suspicious thing as it stands."

"Let's go, let's go first, I'll report to Team Leader Fan."

"Okay, let's go."

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

Lin Yao pushed the door in, and everyone immediately turned their eyes on him.

"How? Kobayashi, did you find anything? ”

Han Bin immediately asked.

Lin Yao looked around at the people in the office, and then said:

"Team Leader Fan has already told you about the previous situation, right?"

"Well, I did."

Everyone nodded their heads.

"Now I have another major discovery here, that is, Zheng Xiang's drink bottle mouth has not been extracted saliva."

Lin Yao also did not contain the lake, and said directly.

Sure enough, after hearing this, everyone immediately began to discuss:

"No saliva? Why did this Zheng Xiang not drink a drink, and the murderer came to the door? ”

"That's right! As I said before, in fact, the murderer didn't know who was drinking the drink at all, but when he saw who bought the drink, he might come and kill him! ”

"No, no, I think..... Whether you buy a drink or drink it or not is not the key to the murderer's murder, the drink is more like a formality. ”

Han Bin shook his head suddenly and analyzed.

"Yes, my thoughts are the same as Brother Han!"

When Lin Yao heard Han Bin say this, he immediately agreed.

Everyone immediately turned their attention to Lin Yao.

Lin Yao continued:

"In the first two cases, there was saliva from the victim himself, but in this case, Zheng Xiang had no saliva at the mouth of the bottle, which means that Zheng Xiang did not drink the drink."

"So according to my analysis, Zheng Xiang is the person the murderer wants to kill, and it has nothing to do with the drink."

"The first two eucalyptus drinks are also the foreshadowing made by the murderer in order to create a drink serial murder."

"Once the foreshadowing is complete, all of us will focus on whether or not to drink the drink with the figure, ignoring the motives of the killer himself."

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

"It can be said that the murderer hitchhiked his own ride by himself!"

As soon as Lin Yao's words came out, the scene was in an uproar.

After a few seconds, everyone agreed!

"Yes, when Xiao Lin said that, I really figured it out!"

"He was so secretive that he thought that with the foreshadowing of the first two eucalyptus, we would be played by him."

"But he forgot that we check if the deceased had a drink."
