According to the contact information provided by the logistics supervisor Lu Yanyan, Lu Ke and his entourage quickly contacted the relevant electrician and met with the other party.

"Yes, I am the electrician in charge of the school's electrical maintenance, and we are all contracted, and we have a contract with the school's general affairs office."

The sudden arrival of the police made the electrician appear a little nervous. He didn't know why the police came to the door, and the first thing he said was to make it clear that there was a contract between himself and the school, and that there were relevant procedures and work permits.

After speaking, he also took the initiative to show his electrician certificate and the school's contract.

"Huang Dashan?"

Lu Ke took the electrician's certificate and carefully compared it with the photo above.

The electrician nodded and looked at Lu Ke seriously: "Yes, I am Huang Dashan, I am from Huangshan." ”

Lu Ke nodded, handed over the relevant documents to Mo Yufei behind her, and asked her to take pictures for keeping.

"Well, comrade policeman, is there something wrong with the school's circuit? It's not time for regular maintenance, and the contract says ......"

Su Simeng looked at Huang Dashan's somewhat nervous appearance, smiled, and slowly explained his intention to him.

Lu Ke settled down and asked him, "When you went to repair the circuit, did the school staff go with you?" ”

Huang Dashan replied, "Yes, there are school security guards who go with us. Actually, I understand that I'm just afraid that we will steal things, which is understandable. ”

"You're in charge of the electrical maintenance of the girls' dormitory, right?" Lu Ke looked at him and asked seriously.

Huang Dashan sat on the sofa, holding a fan in his hand and kept fanning: "There are three electricians in the school, and we are all in charge of the circuit maintenance at the same time in different areas, and I am in charge of the girls' dormitory area." ”

"Tell us about the process." Lu Ke stood across from him and said lightly.

Huang Dashan's brows furrowed slightly, he looked at Lu Ke with some puzzlement, and replied casually: "It was the security guard who led us into the dormitory building, and then we began to cut off the power and carry out circuit maintenance......"

Seeing that Huang Dashan couldn't get to the point, Su Simeng stepped forward and asked him, "Which security guard is it?" ”

"It's the security guard at the school, it's a young man." The fan in Huang Dashan's hand shook faster and faster, and he said casually.

Su Simeng asked him again, "Can you describe what that security guard looks like?" ”

Huang Dashan hesitated for a moment, and said lightly: "It's a young man in his twenties, not tall, and he still has pimples on his face. ”

Speaking of this, everyone was stunned.

"Yue Yushi? The little security guard at the door? Mo Yufei's face was full of shock.

Everyone is also more excited, if this Yue Yushi is the thief who entered the bedroom to steal socks, there is a high probability that he is the murderer in this case.

In this way, several people had just met with the murderer yesterday afternoon.

However, everything is still just speculation and needs to be further confirmed.

"I don't know what his name is." Huang Dashan shook his head, indicating that he had never heard the name Yue Yushi.

Lu Ke looked at him and asked seriously, "Is it this security guard who goes in with you every time?" ”

Huang Dashan nodded and replied, "Yes, it's him every time." ”

Lu Ke continued to ask, "Has he been with you since he entered the girls' dormitory?" ”

Huang Dashan shook his head, his expression suddenly became a little strange, and he whispered: "No, he is sneaky every time, not so much because he is afraid that I will steal things, but I look at him like a thief." ”

Lu Ke asked him with some uncertainty: "You mean, the security guard who went in with you is a thief?" ”

Huang Dashan slowly raised his head, stared at him, and said with a smile: "No, no, I just feel that he is sneaky, like a thief, I didn't say that he stole things." ”

"It's okay, just tell us the details of the situation." Su Simeng on the side answered.

Huang Dashan took a deep breath, and the speed of shaking the fan in his hand slowed down: "Every time I go to repair the circuit, the little security guard goes in with me, I go to the power distribution room on the first floor for maintenance, and he is responsible for going to each floor to check the power outage of the electric switch."

I just feel like it, every time he goes in with me, he looks so excited.

To be honest, after all, it is a child, and it can be understood. But after he entered the building, he looked left and right, and he looked sneaky, which was very strange.

But after all, this has nothing to do with me, so I went to the distribution room to repair the circuit.

But every time I finished repairing the circuit, I had to wait for him at the door of the dormitory building for a long time, and he would always come down from the upper floors with a black pocket in his hand.

Every time, I don't know what's in that pocket. ”

After hearing this, Su Simeng immediately threw a look at Lu Ke.

Mo Yufei said in a snort: "Yue Yushi can't be the thief who stole things, right?" ”

Lu Ke paused, and said slowly, "It seems that we should re-investigate this young little security guard." ”

The conversation between the two was very quiet, but it was still heard by Huang Dashan.

He put down the fan in his hand, raised his head, and asked with wide eyes, "Is there really something lost in the dormitory?" I didn't do it, if I lost something, it was stolen by that little security guard! I'll just say, why does he sneak around every time, it turns out that he is really a thief, and the security guard steals things, doesn't this belong to the prison guard's self-theft?! ”

Huang Dashan instantly gained confidence, and followed the policeman's words to add fuel and vinegar: "You must arrest him as soon as possible, because he has stolen more than once, just by going to repair the circuit with me, there have been three or four times, and each time he has stolen a bag full of things, I don't know what is inside." ”

Leaving the home of electrician Huang Dashan, Su Simeng immediately drove, and several people drove towards Jing'an Vocational and Technical College.

According to the results of the current investigation, security guard Yue Yushi is suspected of entering the girls' dormitory to steal socks under the pretext of work.

Then he is also a very important suspect in this murder case.

In any case, finding Yue Yushi is the key to this case.

When I arrived at the vocational and technical guard room in Jing'an City, there was an old man sitting inside, and after inquiry, Yue Yushi did not go to work today.

At ten o'clock in the morning, a police car drove into a neighborhood near the school.

After an investigation of Yue Yushi, the police have determined the specific address of Yue Yushi.

At the same time, Ling Zizhen had already led the team to complete the blockade of the downstairs of Yue Yushi's house.

Lu Ke opened the car door and got out of the car and asked, "Have you checked further?" ”

Ling Zizhen nodded: "It has been verified, Yue Yushi lives in 201 of this building, it is a house he rents, and he currently lives alone." According to the identity information inquiry, he played all night at a nearby Internet café last night, and he should be sleeping at home at this time! ”

The scene has been arranged, and the group walked into the residential building and walked to the door of room 201.

They stood in two teams on either side of the door, and Lu Ke gave him a look.

Ling Zizhen blocked the door mirror of the door, Su Simeng stepped forward and knocked on the door twice, raising his voice: "Hello! I'm from the community property, please open the door. Is anyone there? Hello? Is there anyone in the house? ”

The shouting and knocking continued for about two minutes, and there was still no response.

Seeing this, Su Simeng leaned down, put his ear to the door and listened carefully, but there was no sound inside.

"No one." Su Simeng mouthed Lu Ke to convey the message.
