Qin Nan looked back, wondering if he was hearing hallucinations. He always felt that the cat was Xiao Hui.
At this time, the black shadow had already disappeared at the entrance of the corridor, and it was unknown where it went.
Teacher Zhao also noticed the dark shadow just now, but seemed to be used to it.
"Teacher Zhao, does anyone have a cat here?" Qin Nan asked
"Probably not. The one just now should be a stray cat nearby. Moreover, cats and dogs are not allowed in the faculty and staff dormitories. They can only keep goldfish, hamsters and the like." Teacher Zhao replied.
Qin Nan also nodded thoughtfully, and not long after, the three of them arrived at the dormitory security office.
It was already lunch break time, and the door of the dormitory office was ajar, and bursts of "earth-shaking" snoring could be heard from inside.
Teacher Zhao walked in front of Ma Xiaotao and gently opened the door. At this time, an uncle about fifty years old was lying on a rest bed.
The snoring from his mouth flowed to his neck, and his upper and lower lips "rhymed" with his snoring.
Teacher Zhao smiled awkwardly at Ma Xiaotao and Qin Nan, and then patted the uncle on the shoulder.
"Lao Zhang, Lao Zhang, wake up?"
"Ah~~" Security guard Lao Zhang stretched his waist and looked at the three people in front of him half asleep.
He rubbed his eyes and saw clearly that the person standing in front of him was Teacher Zhao. He suddenly woke up and asked with a smile in southern dialect:
"Hey, Teacher Zhao, what a shame, you two are..."
Teacher Zhao and Lao Zhang lived in the same community nearby, and she accidentally learned about the situation in Lao Zhang's family.
Lao Zhang's job was arranged for him by Teacher Zhao. Lao Zhang couldn't find a job because he was old and uneducated. There was also a patient at home who was taking medicine.
At that time, the school staff dormitory also happened to be short of a security guard. Teacher Zhao reported the situation at his home to the school human resources, so he was assigned such a job.
"They are comrades from the police, here to investigate the case. Lao Zhang, do you know how to adjust the surveillance now?" Teacher Zhao asked
"Of course, I just helped a teacher find a surveillance camera two days ago." Lao Zhang said.
"Yeah, not bad." Teacher Zhao gave a thumbs up, and Lao Zhang scratched his head in embarrassment.
"No, it's the surveillance camera." The uncle frowned and looked at the surveillance camera in surprise.
"What's wrong?" Qin Nan also asked anxiously.
"It's okay, it's okay. This computer is a little stuck. I'm going to do a few more things and I'll check it out soon." The uncle said with a frown, as if he had encountered some problem.
"Uncle, do you know who has been monitoring the surveillance in the past two days?" Qin Nan asked with a frown.
"Well, I remember that the teacher's surname seemed to be Xiao, and he seemed to be looking for a thief." Lao Zhang touched his chin and recalled.
"Is your name Xiao Lu?" Qin Nan asked.
"My enemy, my enemy, my name is Xiao Lu. I even registered you." After finishing speaking, Lao Zhang handed over the registration form on the table in front of him.
Strangers will make a visitor registration, and the person calling for monitoring will also make a registration and explain its purpose.
"Is there only surveillance in this dormitory here?" Qin Nan asked.
Lao Zhang nodded with certainty.
At this time, Qin Nan seemed to have thought of something, and he hurriedly said: "Uncle, take a look to see if there is any surveillance from November 23 to now!"
"Yeah, what the hell, something is wrong." The uncle scratched his head and said.
"Is the surveillance gone?" Qin Nan said with a frown.
"Damn it, it's impossible. He disappeared after a while." The uncle moved the mouse anxiously.
"Uncle, let me do it." Ma Xiaotao stepped forward, and the uncle also stood up and stood aside, scratching his head in confusion.
"Uncle, can this monitoring be deleted?" Qin Nan looked at the uncle and asked.
"Don't be afraid. There are three months of monitoring records in it. The monitoring records from three months ago will be automatically deleted. There is no automatic deletion function at all." The uncle said blankly.
"Yes, that's true. Our school's monitoring system only saves monitoring records for the past three months, and there is no automatic deletion function." Teacher Zhao continued.
"This computer has been tampered with." Ma Xiaotao sighed and said to Qin Nan.
Qin Nan thought for a while and said to Lao Zhang: "Uncle, from November 23, that is, from yesterday to now, has anyone touched this computer?"
Lao Zhang put his hands on his hips, thought for a while, then clapped his hands and said, "I know, it must be that Teacher Xiao. At that time, he told me that there was a teacher upstairs looking for me.
Let me go up and take a look, I left here during that time."
Qin Nan and Ma Xiaotao sighed. In fact, Qin Nan had already expected such a result. He came to the monitoring room just to verify his guess.
Also to make Ma Xiaotao aggravate the suspicion against Xiao Lu.
He looked at Ma Xiaotao. At this time, she was frowning and staring at the screen in front of her in a daze, not knowing what she was thinking.
At this time, the room fell into silence, and Teacher Zhao and Lao Zhang didn't know what to say.
After a while, Ma Xiaotao sighed, frowned, took out his mobile phone and made a call:
"Hey, Captain Song, I'm Xiaotao, and I'd like to apply for a search warrant."
"What's going on? Is there any new progress in the case? Whose search warrant is it?"
"Xiao Lu's? We now have sufficient evidence that she is related to this case?"
"Are you sure? What do Qin Nan think? Is he next to you? Let him answer the phone."
Ma Xiaotao looked at Qin Nan, and then handed the phone to Qin Nan's hand.
"Hey, Brother Song."
"Is there sufficient evidence to prove that it is related to Xiao Lu?"
"Yes, now all the surveillance cameras in the faculty and staff dormitories have been stolen by her."
"Okay, go ahead and leave the rest to me. I will handle the search warrant for you right now."
Song Yi then hung up the phone, and Qin Nan nodded to Ma Xiaotao.
At this time, Teacher Zhao said: "Are you going to break the door later? I'll report it to the school and explain the situation."
Then Teacher Zhao made a phone call on speakerphone:
"Hey, Dean Li, the police comrades here are going to break open the door and search Teacher Xiao's dormitory. What do you think?"
"What, what happened again?"
"Hey, the police comrades are investigating the cases of the past two days. It seems that Teacher Xiao is related to these two murders."
"Okay, I'll be right over. You and the police comrades go there first, and you call the school's maintenance master."
After saying that, the other party hung up the phone. It seemed that Dean Li would also come over.
So Teacher Zhao made a call, and soon the school's maintenance man rushed over, while security guard Zhang stayed in the room and continued to watch the surveillance.
Qin Nan and Ma Xiaotao were silent at this time, both thinking about their own problems. Ma Xiaotao hoped that this case would not be related to his sister.
She wanted to find the truth quickly and confirm her thoughts, so she applied for a search warrant from Team Song.
"Click." Not long after, the door was pried open by the maintenance man.
There was no one in the room, except for two rows of succulents on the window sill. Most of them were Toba Jade, which is used to extract mescaline, and was placed under the window sill...
