After walking to the scene inside, Lin Yao saw Fan Jun and other police officers in the group standing in front of the container where the migrant workers lived.

"Team Leader Fan."

Lin Yao stepped forward and greeted Fan Jun.

"Xiaolin, you're here!"

Fan Jun heard Lin Yao's voice and immediately turned around.

Several other colleagues couldn't help but look at Lin Yao with some surprise.

"What's going on now?"

Lin Yao went straight to the point and asked him.

"Oh, that's what happened."

Fan Jun's face immediately became serious, and then he said to Lin Yao:

"The deceased inside is called Zhang Zhike, a migrant worker, who was stabbed three times, all in the chest, and the time of death was about six o'clock."

"According to the deceased's co-workers, they had all ordered food, and every afternoon after work, a delivery person would bring the food."

"But when the delivery man went out today, he found that the electric car suddenly broke down and could not be delivered."

So they discussed going to a nearby food stall to eat.

"At that time, Zhang Zhike went back to sleep in the container after work, and the workers called him and said that he would not eat tonight, so the others left."

"When they came back from eating, they found Zhang Zhike lying in a pool of blood."

After hearing this, Lin Yao nodded slightly, and then asked:

"Has his relationships been investigated?"

"According to his co-workers, he is an introvert, a foreigner, and he has no friends here, let alone any enemies he has, and he works on the construction site every day."

Fan Jun frowned and shook his head and said.

"In this way, this eucalyptus is a little difficult to handle."

Lin Yao nodded slightly after listening.

A person with such simple social relations was suddenly killed.....

"I'll go in and have a look."

Then, Lin Yao raised his head and said to Fan Jun.

"Well, in there."

Fan Jun pointed to the container behind him and said to him.

Lin Yao put on shoe covers and gloves and walked in.

At this time, the personnel of the technical squadron were taking pictures and examining the body.

Lin Yao looked inside.

There were six bunks in the container, and on the ground near one of the bunks near the door, I saw a corpse lying in a pool of blood.

Lin Yao glanced at it, then looked around.

He saw an empty bottle of drink on the windowsill.

"Excuse me, I'll borrow it."

Lin Yao walked past the police officer of the technical squadron and walked towards the windowsill.

He picked up the empty bottle and saw that it was a juice drink, and the drink inside had been drunk completely.

He opened the cap and looked at the mouth of the bottle, and when he was about to close the cap, suddenly, he saw that there was a strange picture printed on the inside of the cap, which was more like a language text, a bit like "Mou".

Lin Yao couldn't help frowning.

This picture is a little abnormal, right.....

Generally, the pictures in the caps of beverage bottles are some QR codes, which can be scanned to redeem prizes.

Or "thank you for your patronage", "another bottle" or something like that.

After thinking about it, Lin Yao's eyes quickly searched for the bottle, trying to find out if there was any information about any prize redemption activities.

However, the bottle of the drink is only printed with some fruit images, and there is no activity.

"What's wrong? Kobayashi. ”

Fan Jun saw Lin Yao frowning inside, so he hurriedly walked in and asked.

"Team Leader Fan, take a look at this bottle cap."

After finishing speaking, Lin Yao handed the bottle cap to Fan Jun's hand.

"Any questions?"

"Look at this picture."

Lin Yao pointed to the inside of the bottle cap.

"This ....."

After Fan Jun saw it, he couldn't help but be a little puzzled,

"I haven't drunk this drink before, so I don't know if there will be this kind of picture in it."

"This picture looks like it's printed."

After finishing speaking, Fan Jun took the drink bottle in Lin Yao's hand and walked out:

"Have any of you ever drunk this drink?"

"No, this kind of drink looks like it's a niche drink...."

"And it's cheaper."

The officers outside shook their heads.

Lin Yao searched around the container again, and suddenly, he saw a woven bag in the corner inside.

He approached and opened it, and there was some garbage and a drink bottle inside, and this drink bottle was the one that had been on the windowsill just now.

"Team Leader Fan! Over here! ”

So Lin Yao hurriedly signaled to Fan Jun.

"What's wrong?"

"There's a bottle of this drink in there."

After Lin Yao grabbed a few from it, he opened the cap.

"There is no diagram."

"Not at all."

Lin Yao and Fan Jun opened all the bottles inside and found that they were all empty.

"So to put it that way.... Is it likely that this picture has something to do with the murderer? ”

Fan Jun touched his chin and thought,

"Could it be... Is this the murderer's signature? ”

I have also encountered some murderers before, and they will deliberately leave their marks at the scene of the eucalyptus.

"I called his co-workers in and asked."

After saying that, Fan Jun hurriedly turned around and asked them to call in the migrant workers who lived in the container.

After a while, five honest-looking migrant workers walked in from outside.

"Who bought this drink?"

Fan Jun held up the drink bottle and asked them.

"I bought this."

One migrant worker immediately admitted.

"Did you notice the picture on this bottle cap?"

Lin Yao pointed the inside of the bottle cap at him and asked him.

"Bottle cap diagram?"

The migrant worker couldn't help frowning, then shook his head again and again and said,

"I don't have that."

"I bought six bottles from outside after lunch today, and distributed them to everyone, I didn't pay attention to any pictures, and I didn't even notice if you didn't say it."

Lin Yao stared at him and asked again:

"Who drank this bottle of drink on the windowsill?"

"This.... I don't know, mine was just outside and threw it away. ”

The migrant worker shook his head, then said.

Subsequently, several other migrant workers also spoke:

"My bottle was thrown out too."

"Mine was thrown in a woven bag for garbage."

"Me too."

.........

After hearing what they said, Lin Yao couldn't help asking:

"So, this bottle of drink on the windowsill is what Zhang Zhike drank?"

"Well, that's it!"

One of the migrant workers nodded, then said.

"Where did you get the drink?"

Later, Lin Yao asked the migrant worker who bought the drink.

"It's the little shop at the entrance of the construction site, where we usually buy drinks and snacks."

The migrant worker replied immediately.

"Okay, I see, you guys go first, if we need your help, we'll call you again."

Lin Yao nodded and said to them.

"Okay, comrade policeman."

Several migrant workers nodded repeatedly, and then said:

"We've had to go out to stay in a hotel these days, but we don't dare to stay here."

"yes, it's too dangerous, I'm scared when I think about it now."

"Brother Zhang, he hasn't offended anyone, but he will be poisoned like this."

"If I was lying in bed at that time, maybe I would have died!"

"Okay, okay, don't think about it until you break it, don't think so much about it, go back and rest."

Fan Jun walked up and patted them on the arm and sent them out.

Then, he turned back, stared at Lin Yao with a solemn face, and said:

"Is it a coincidence that the six of them bought six bottles of drinks, and only the deceased's drink had this picture printed on it?"

Lin Yao frowned and pondered for a moment, then said:

"The picture on the bottle cap was printed, I don't know if the picture was there before the deceased drank it, or after the murderer killed the deceased."

"But I think it's a little more likely that I had this picture before I drank it."

After Lin Yao finished speaking, Fan Jun immediately said:

"In that case, the person who buys this drink will die?"

"That is, the murderer may not have had anything to do with the deceased, and he was killed only because he drank a drink with a eucalyptus printed on it?"

"Possibly."

Lin Yao nodded.

"Then it looks like an investigation is going to be carried out into the supply channel of this drink."

Fan Jun thought for a while and said.

At this moment, Han Bin walked in from outside.

"Team Leader Fan!"

"How?"

Fan Jun looked at him and asked.

"Just now I asked the janitor at the construction site if he saw any suspicious people coming in and out at about six o'clock, and he said no."

Han Bin immediately reported,

"But when I saw his gaze dodging, I felt that something was wrong."

"So under my questioning, he admitted that at half past five he received a phone call, saying that his wife had a sudden heart attack at home and asked him to go back quickly."

"But when he went back, he found that his wife was fine at home and there was no problem."

"And I asked him, who knows his phone number."

He thought about it and said that only a few friends and family members knew.

"The things on the construction site are all left by the phone number of the guard room, and there is no mobile phone number for him."

After listening, Fan Jun's brows furrowed even deeper.

"It seems that this murderer is very powerful and can arrange all the links."

Then, he raised his head again and asked Han Bin:

"Have you checked the surveillance nearby?"

"I checked, but I didn't see anything."

Han Bin shook his head.

"I guessed it a long time ago."

Fan Jun was not surprised, but nodded slightly.

If this murderer made all aspects interlocking and seamless, and left his video in the surveillance, it would be abnormal.

"Okay, let's close the team first, and check tomorrow morning."

Then, Fan Jun looked at Lin Yao and said.

Immediately after, he sighed:

"It is estimated that this matter has now reached the ears of the leaders of the city bureau, and he must have a headache if we have been dying here one after another recently."

"Let's go!"

With that, he beckoned and walked out.

"Team Leader Fan, I'll come here tomorrow to investigate, mainly to investigate the problems about beverages."

After coming out, Lin Yao said to Fan Jun.

"yes, okay."

Fan Jun nodded, "

"Find someone to be with you."

"I'm coming!"

Cao Lin, who was on the side, listened to their conversation, and immediately raised his hand and walked over.

Lin Yao turned his head to look at him and smiled slightly, then said:

"That's okay, Team Leader Fan, just let him come with me, we also had some tacit understanding before."

"Well, that's fine."

...........

At seven o'clock the next morning, Lin Yao and Cao Lin met near the construction site.

"The convenience store they are talking about should be this one!"

Lin Yao stood at the intersection and pointed to a convenience store in front of the clearing.

"Well, I just looked, and this convenience store is the closest to the construction site. The migrant worker said that he bought it at the convenience store at the entrance of the construction site, which should be the one he was referring to. ”

Cao Lin nodded.

"Let's go, go in and have a look."

After Lin Yao finished speaking, he walked directly to the convenience store.

At this time, the convenience store owner had just opened his doors and was tally.

"Hello, boss, we are from the Municipal Criminal Police Team."

Since the two of them are wearing police uniforms today, they don't need to bother to introduce them.

So Lin Yao directly took out his ID and said to him.

Hearing the voice, the boss immediately put down the goods in his hand, and then turned around.

"Hello, comrade policeman! I heard about it, and I saw it in the group last night, saying that someone died at the construction site last night, and you guys are here to investigate this matter, right? ”

The boss looked at Lin Yao and the two and said immediately.

"Yes, that's right."

Lin Yao nodded, and then said to Cao Lin:

"You ask the boss to help adjust the monitoring in the store to see if there are any suspicious people near the time when the deceased worker buys drinks."

"Okay."

Cao Lin agreed, and then said to the boss:

"Boss, there's surveillance in your store, right?"

"Yes, there's not just one at the door."

The boss nodded and pointed to the camera above the door.

"Okay, you can call up yesterday's monitoring for me."

"Okay."

Lin Yao saw that the two of them were adjusting the surveillance, so he walked inside by himself.

Soon, he found the drink in the deceased's room on the shelves.

Lin Yao walked out with a drink and asked the boss:

"Boss, where did you get this drink?"

"This ....."

After the boss heard Lin Yao's question, he immediately hesitated.

"Suppliers are trade secrets, I'll tell you......."

"What a trade secret! I won't tell anyone that I think I'll open a convenience store to steal business from you! ”

After Lin Yao heard his words, he suddenly felt helpless,

"I'm telling you, this drink may be involved in this eucalyptus, you must tell me the truth! Do you hear that? ”

"Okay, okay."

When the boss heard Lin Yao say this, he was immediately a little scared, so he nodded again and again.

"Tell me, where did this drink come from?"

Immediately after, Lin Yao asked him again.

"This drink was given to me by a supplier, wait a minute, I'll give you his contact information now."

After finishing speaking, the boss took out his mobile phone and looked through the address book.

"Will there be anything wrong with this drink? You may not know much about this drink, but there is still a certain market near the construction site. ”

"After all, his price is cheap, and the volume is not small."

As he spoke, the boss found a saved mobile phone number and handed it to Lin Yao.

"That's the man."
