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

Chapter 231 Did someone outside do it?
After they went out, Lin Yao's mood didn't fluctuate much.

"Based on my experience, the murderer was not among them."

Lin Yao was also unambiguous, and said directly to Yao Jin.

"Well, indeed, it's not like they're lying by looking at their expressions."

Yao Jin also nodded in confirmation.

Then he couldn't help but say:
"Then where do we start next, to investigate the relationship of the deceased?"

"I also read the clues of this case, and I feel that there is still a high possibility of vendetta."

Lin Yao didn't speak immediately after listening, but looked ahead and thought for a moment, and then said:
"There is no need to investigate the relationship between people for the time being. Captain Zhang and the others have questioned the employees in the factory in the past few days, but they didn't find any enemies of the deceased."

"That's it, then tell me, what shall we do next."

Yao Jin nodded slightly, and then said.

"I think our breakthrough should be why the deceased went back to the roof at that time, and who invited him up. This person must have a lot to do with the case."

Lin Yao stared at the front and spoke.

Yao Jin also frowned and said:
"Yeah, for no reason, he couldn't run to the top of the building by himself. And the murderer was in ambush on the top of the building and killed him."

"It's unreasonable, and I also think someone called him up."

"But... how do we check? By the way, Captain Zhang, have they retrieved the deceased's mobile phone records?"

After speaking, Yao Jin looked at Lin Yao and asked again.

Lin Yao shook his head and said:
"There is no call record in the mobile phone. I don't know if it was deleted by the murderer or what reason."

"However, we can arrange for someone to investigate with the communication service provider, and you can arrange it later."

"Ok, no problem."

Yao Jin immediately nodded in agreement.

"Let's go first."

Afterwards, Lin Yao stood up directly from the chair and walked outside.

"Huh? Brother Yao, have you decided where to go?"

Seeing Lin Yao standing up suddenly, Yao Jin couldn't help asking in doubt.

"Go to the factory where the incident happened."

Lin Yao said and walked out of the room door.

"okay!"

Yao Jin immediately agreed, and quickly followed out.

After going out, Yao Jin drove directly to the gate of the factory.

When Lin Yao got out of the car, the security guards in the guard room greeted him immediately.

He already knew Lin Yao, so he quickly took out two cigarettes and handed them to Lin Yao and Yao Jin.

"Comrade police, you have worked so hard, here we go again!"

The security guard looked at Lin Yao and said with a smile.

Lin Yao nodded, then looked at the security guard.

This security guard looks about 40 years old, of medium height, with a slightly fat body, but he looks a bit simple and honest.

"Come on, Master Wang, let's go in first."

Lin Yao lit the cigarette, then pointed to his guard room and said.

"Hey, good."

The security guard quickly agreed, and then walked in with Lin Yao and the others.

"Comrade police, drink water!"

After entering the guard room, security master Wang quickly picked up his green thermos, then took two disposable water cups from the side, and poured two cups of hot water into them.

"Thank you."

Lin Yao took it and took a sip.

"Master Wang, have you been on duty here these days?"

Lin Yao looked around the room, and then asked.

"Yes, since the accident, I have been on duty here myself."

Master Wang took a few swigs from his teacup, then nodded and said.

"You are on duty yourself? How many security guards are there in your factory?"

Lin Yao asked him in a surprised tone.

"There are a total of four security guards in the factory, but since the accident, haven't all the workers in the factory returned, and the factory has not started working."

"And I was on duty the day the accident happened, so let me guard here alone, so that when you come to investigate and ask about the situation, I can answer you, which is also convenient."

Master Wang explained to Lin Yao.

Lin Yao nodded slightly and said:
"Oh, so that's the case. Then you have worked hard during this time."

Master Wang shook his head and smiled, and said:
"Hi! What's the trouble? I just sit in the guard room and look at my phone every day, and nothing happens."

Afterwards, Lin Yao's expression became serious, he looked at him and asked:
"Master Wang, on the night of the incident, were you sitting in the guard room, or were you patrolling outside?"

Master Wang was taken aback for a moment, then immediately replied:
"I'm sitting in the guard's room."

"Because the workers were working overtime in the workshop at that time, no one left, and I had nothing to patrol."

"Ah."

Lin Yao nodded slightly after listening, and then continued to ask:

"By the way, Master Wang, is there any monitoring in the workshop?"

"Yes, there is monitoring."

Master Wang immediately nodded and replied.

"Where is that, show us there."

Lin Yao stood up directly from his seat, and then said.

"This"

Master Wang hesitated for a moment, then said to Lin Yao,

"I can't show you this, you have to call Xiao Cheng, who is in charge of monitoring in the factory."

"However, after the accident, your people have already watched the surveillance. Do you still need to watch it?"

After finishing speaking, Master Wang looked at Lin Yao.

Lin Yao nodded, and then said:
"Then please call this Xiaocheng over, we have to take a look."

"Okay then, just wait a moment."

Master Wang saw that Lin Yao insisted on watching.

So he nodded in agreement, then took out the phone from his pocket, and made a call.

"Hello? Xiao Cheng, where are you now? Sleeping at home? Hurry up and come to the factory."

"The police comrades who come to investigate the case need to watch the surveillance of the workshop. Yes, it is now, hurry up."

After finishing speaking, Master Wang hung up the phone and said to Lin Yao:

"Comrade policeman, wait a moment, he will be here soon."

"Well, okay, sorry to bother you."

Lin Yao nodded and said to him.

After a while, a man in his 30s hurried in from outside.

"Old Wang, who wants to watch the surveillance?"

He asked immediately after pushing the door open.

Afterwards, his gaze turned to Lin Yao and Yao Jin in the guard room.

He first looked at Lin Yao in surprise, then immediately reacted and greeted Lin Yao and the others:
"Comrade police, you are the ones who want to watch the surveillance, right?"

"Yes, please take us to see the monitoring of the workshop."

Yao Jin said directly from the side.

"Okay, you come with me."

Xiao Cheng nodded cooperatively, then turned and walked out of the guard room.

"Comrade police, you just go with him."

Master Wang pointed to Xiao Cheng who went out, and said to Lin Yao and the others.

"Ok."

Lin Yao nodded with a smile, and then followed him out.

After coming to the monitoring room, Xiao Cheng quickly turned on the machine.

"Do you want to watch the video of the night when the incident happened?"

Xiao Cheng asked Lin Yao while operating the computer.

"Yes, I started watching it at eight o'clock on the night of the post."

Lin Yao stared at the computer screen tightly, then nodded and said.

"Okay, wait a moment."

Xiao Cheng agreed, and then performed some operations.

"All right."

"Play at 3x speed."

"it is good."

Lin Yao stared closely at the screen and began to watch.

After watching the video at 09:30, Lin Yao nodded and said to Xiao Cheng:
"Okay, let's pause."

After finishing speaking, he walked out of the monitoring room directly.

Seeing this, Yao Jin quickly followed out.

Lin Yao looked at the front of the corridor and said:
"I have watched the surveillance video just now. During this period of time, a total of twelve workers left the workshop, but the worker who left for the longest time left for about 10 minutes."

"From the workshop to the dormitory, killing the deceased on the roof, and then dragging his body to the warehouse below, 10 minutes is certainly not enough time."

After hearing Lin Yao's words, Yao Jin couldn't help being a little surprised.

He didn't expect Lin Yao's memory to be so good.

He also watched the surveillance video just now, but Xianza's mind was not so clear.

Unexpectedly, Lin Yao memorized all these key information after reading it so once.

Afterwards, Yao Jin looked at Lin Yao and asked:

"In that case, the murderer probably wasn't someone from the factory?"

"After all, the three female workers resting in the dormitory have been basically ruled out as suspects, and the workers on duty in the workshop don't have enough time."

Lin Yao nodded slightly, then frowned and said:
"Could it be that people from outside the factory entered the factory to commit murder?"

"Go, go to Master Wang first."

After finishing speaking, Lin Yao walked into the monitoring room and said to Xiao Cheng:
"We've finished watching, you can go back."

"Don't read it, right? That's fine, I'll go first, anyway, if you need my help, you can just ask Lao Wang to call me."

Xiao Cheng who was sitting inside quickly got up from his chair when he heard it, and said to Lin Yao.

"no problem."

Lin Yao nodded, then turned and walked out.

After coming out, the two went directly to the guard room downstairs.

"Are you finished?"

Master Wang was sitting inside playing with his mobile phone. He didn't expect Lin Yao and the others to come down so soon.

"Ah."

Lin Yao nodded slightly.

"Have you found anything?"

Master Wang asked Lin Yao curiously.

"We have seen that the overtime workers in the workshop did not go out for a long time."

"However, Master Wang, let me ask, do you know if all the workers in the workshop are at their posts, and there are no absenteeism?"

Lin Yao looked at Master Wang and said.

"Absent from work? That's impossible!"

After listening to Master Wang, he immediately shook his head, then said with a smile:

"If someone is absent from work, the workshop director has to be unwilling!"

"After all, everyone's work is assigned. If someone doesn't come, then the work can't be done!"

After Master Wang finished speaking, he saw that Lin Yao hadn't spoken, so he hurriedly said:

"If you are worried, I will call the workshop director and ask him to come over."

"Anyway, the factory is not working now, and they have nothing to do. The main thing is to cooperate with you in investigating the case."

"Well, that's fine, you can call him."

Lin Yao nodded directly and said.

After a while, the workshop director also came to the guard room.

"Comrade police, are you looking for me?"

After he came in, he immediately looked at Lin Yao and the others and asked.

Lin Yao stared at him, then asked:

"Are you the workshop director?"

"Yes, I am."

"Were you in the workshop on the night of the incident?"

So Lin Yao asked straight to the point.

"I'm in the workshop! Do you have any questions?"

The workshop director looked at Lin Yao suspiciously and asked.

"That night, except for the three female workers who asked for leave, did everyone work overtime in the workshop?"

Lin Yao continued to ask him.

"Yes, of course, who dare not come to work overtime without asking for leave."

After the workshop director heard Lin Yao's question, he said it immediately without thinking.

"Are you sure? There will be no missing personnel?"

Lin Yao stared at him and confirmed.

"Yes, I'm sure!"

The workshop director immediately said, and then explained,
"I usually work overtime like this at night. After eating and starting to work, I always have to patrol the workshop. If there is no one in any position, I can see it at a glance."

"So I'm pretty sure all the workers are there."

Seeing his affirmative expression, Lin Yao couldn't doubt anything anymore.

Afterwards, Lin Yao continued to ask him:
"The dead Liu Liang, do you have a deep understanding of his situation?"

After Lin Yao finished speaking, the workshop director frowned, thought for a while and said:

"To be honest, I really didn't expect this little Liu to be killed in the factory."

"This kind of thing can still happen in the factory!"

"Ugh"

As he spoke, the workshop director couldn't help but shook his head and sighed.

Afterwards, he immediately reacted, and then looked at Lin Yao and said hastily:

"You ask me, do I know Xiao Liu? It's okay, he has worked in our factory for three years, and I am quite familiar with him."

"What should I say about him, sometimes he really likes to be lazy."

"Including when he said he was not feeling well that day and came to ask for leave with me, I thought he was trying to make excuses for being lazy."

"But he said he was not feeling well, and I can't force him to work overtime, are you right?"

"This happened unexpectedly"

Lin Yao stared at the workshop director, and then continued to ask:
"When he was working in the workshop, did he ever have conflicts with any of his fellow workers?"

"This. Probably not. At least I don't know."

The workshop director thought for a moment, then shook his head and said,

"Xiao Liu is relatively honest on the whole, and he is not the kind of person who is not very serious."

"As for which worker you said he had conflicts with, to be honest, it's hard to say."

"By the way, your colleagues seem to have asked the workers in our factory before, and they probably all said they didn't know."

"Comrade police, I think your detection target should not be placed on the employees of our factory."

"Because I just said that our workers were all working in the workshop that night, and we are all serious workers. How could there be murderers!"

"Maybe it was done by social personnel who ran in from outside!"

After finishing speaking, the workshop director looked serious.
