Just be Cheng Shao's apex treasure

Chapter 412 Investigation
The clouds at night are big and quiet.

In addition, the night before, a murder case occurred in the laboratory building of the medical school, and a student of the hospital died, so the laboratory building was temporarily closed. no one.

Lu Guo stood in front of the sealed laboratory building, looked up, did not go in immediately, but walked around first.

"How? Did you find anything?"

Suddenly there was a voice behind him, and Lu Guo turned around.

Zhan Honghui stood about two meters away from him, saw him turn around, and pulled the corner of his lower lip at him, "Do you want one?"

Zhan Honghui held a pack of cigarettes in his hand, smoked one and asked Lu Guo.

Lu nodded.

Zhan Honghui stepped forward, handed him one, and then polished the lighter.

"Thank you." Lu Guo held the cigarette in his mouth, lowered his head, put the cigarette on the flame and lit it, took a puff, and looked into the distance.

Zhan Honghui himself lit a cigarette and began to puff.

After taking two puffs, Zhan Honghui said: "I have observed that every floor of this laboratory building is equipped with surveillance cameras. Except for the public toilets, it can be said that other corners are 360 ​​degrees without dead ends. If it is daytime, someone appears here In the laboratory building, it will definitely be photographed by the probe, but unfortunately, it happened at night. The lights in the corridor of this laboratory building are voice-activated lights. When I left the laboratory on the first day of the new year, there was movement, and the voice-activated lights were on for a few seconds. The surveillance captured the picture of her leaving, but she may have walked very lightly when going down the stairs, and did not turn on the voice-activated lights on the stairs, so the surveillance did not capture her afterwards, and it was not until she walked out of the laboratory building that she was photographed again .”

"Could it be something wrong with the voice-activated lights in the corridor?" Lu Guo said his guess, "I watched the surveillance video, the shoes she was wearing last night were small white shoes, and the soles were not like sneakers Soft, walk normally, if you don’t step lightly on purpose, the voice-activated light will be on, not to mention that she is going down the stairs, there is no need to lighten her footsteps, the sound will be louder than on flat roads, the voice-activated light is not on , which is very strange."

Zhan Honghui nodded, "Yes, I've thought about it too, so I went up and down the stairs and walked up and down a few times. Normally, the voice-activated lights will be on when I go down the stairs, and I asked the floor manager. They will be inspected one by one, and any broken lights will be replaced in time. He said that when he checked yesterday morning, he found some problems with the lights between the 4th and 3rd floors. They have been replaced with new ones, and the rest of the lights are normal. And every day he kept a record of when and where the lights were changed. I read the records. In addition to the lights on the stairs between the 4th and 3rd floors, he replaced one in the corridor on the 6th floor that day. "

"Then have you noticed that these lights are replaced frequently?"

"It has been more than 10 years since the laboratory building was built. The administrator has always been Lao Wu. He is a very careful person and has records of everything he does every day. For more than ten years, he has a thick stack of notebooks. I don't have one. I only read the ones in the last three months. In the three months, I changed the lights 9 times, 5 of which were in public toilets, and the other 4 times. One was yesterday. Lao Wu told me that the school bought The quality of these voice-activated lights is not bad, and the average lifespan is 2 to 2.5 years."

Lu Guo was silent when he heard the words, but being silent didn't mean he didn't have a clue.

Zhan Honghui looked up at the laboratory building, took two puffs of cigarettes, and then said, "Have you ever asked about the first day of junior high school? According to the surveillance video, when she left the laboratory and locked the door, she seemed to have found something. Turn around."

"I didn't ask, she's emotionally unstable." After Lu Guo finished speaking, he paused for a moment, and then said, "But according to my father, she said that she felt someone following her after she got home, but she didn't see anyone when she turned around. "

"Feel like someone is following her?"

"That's what my dad said."

"This girl, she didn't tell others about such an important matter, why didn't she tell me? I asked her if she had noticed anything unusual when she left the laboratory building last night, and she told me no."

Lu Guo glanced at Zhan Honghui, "You're not her brother, how could she trust you?"

"Why am I not her brother? Are you and I brothers? Is your sister my sister?"

"It's just your wishful thinking. Besides, you call the police every time something happens to her. Do you think she has a good impression of you? Even if she knows that you and I are brothers, she can't trust you, let alone ..."

Having said that, Lu Guo didn't say anything further.

"What's more?" Zhan Honghui asked.

"Besides, she already has me and her second brother. Do you think you are redundant?"

Zhan Honghui felt particularly uncomfortable hearing these words, "Why am I called superfluous? Wouldn't it be good for one more person to love her?"

"Of course, but have you shown your elder brother's love for her younger sister and let her know?"

"I……"

Zhan Honghui opened his mouth and snorted, "You talk so much, it's stingy to put it bluntly! You're just too possessive, you think I'll take your baby sister away."

"That's not true at all."

Lu Guo smiled, lost in memory.

When she was a child, Yibao asked her if her second brother was called "Second Brother", but "Brother" just like calling her.

In fact, at that time, she didn't have much idea of ​​the "big" and "two" of the eldest brother and the second brother. She thought that the elder brother was the elder brother, you were my elder brother, he was also my elder brother, and you were all my elder brothers, so she saw him and called him elder brother. When she met her second brother, she also called her elder brother, and when she saw the two of them together, she called each of them elder brother.

But he was upset because he felt that this "brother" was his exclusive, and "her brother" could and could only be him, and no one else could.

But she was too young at that time. Every time he told her to ask her to call him brother and her second brother to be called second brother, she promised well at the time, but she forgot when she turned her head. He had no choice but to clean up Lu Ren. .

So at that time, Lu Ren was often dealt with by him, and it is estimated that Lu Ren did not know why he suffered so much when he was a child.

Now that I think about it, I was pretty bad back then.

It's not good enough because she was a latecomer and finally realized her problem, or maybe it was because of his persistent confession that she finally changed her mind, so this "brother" became a title exclusive to him.

This should be the possessive desire that Zhan Honghui was talking about, but he didn't understand it at that time.

Lu Ren was really wronged.

Ugh!
Lu Guo sighed, remembering that Lu Ren would also come back after a while, and Yibao would definitely stick with him often, and his elder brother would probably be left alone.

"By the way, how long does it take to leave from the 4th floor to the outside?" Lu Guo asked suddenly.

After taking his last puff of cigarette, Zhan Honghui replied: "From the stairs on the fourth floor to the first floor, if a person walks at a normal speed, it takes about 1 minute and 20 seconds. From the stairs on the first floor to the exit, it takes about 20 minute and 1 seconds. 40 seconds, a total of about 3 minute and 1 seconds, but it took 40 minutes and 1 seconds last night on the first day of junior high school, excluding 30 minute and 5 seconds, there is still [-] minute and [-] seconds to kill a person in such a short time, theoretically The above can be established. And if you follow the normal walking route, go down to the first floor and turn left about [-] meters away, then turn left again, and you can go straight to the exit. According to the footprints on the scene, the first step down the stairs After reaching the first floor, she did not turn left first, but turned right and then came back before leaving. Moreover, the footprints to the right were deliberately erased, leaving only two omissions that were not erased. If there is no murder, then this is a well-designed bureau, and the only evidence now all points to the first day of the junior high school, she is the suspect, and the scene where Shang Linru was killed was severely damaged, because it was In the morning when students come to class to do experiments."

Lu Guo frowned slightly when he heard this, "So, you mean, I can't help Yibao get rid of the suspicion?"

"It's not impossible. It's not easy for you to find evidence in favor of the first day of junior high school."

"As long as you are human, no matter how carefully planned, there will be loopholes. There is no perfect person in this world, let alone a seamless plan!"

Lu Guo believed that as long as he calmed down, he would be able to find a loophole.

"Do you want to look for evidence with me?"

After smoking a cigarette, Lu Guo threw the cigarette butt on the ground and crushed it with his feet, then squeezed it up and threw it into a nearby trash can, asking Zhan Honghui.

Zhan Honghui shrugged his shoulders, "Otherwise, what am I doing here? I haven't done investigation with the captain for many years."

"There will be opportunities in the future."

"That's not necessarily the case, you are now the Lu Bureau."

"What happened to the Land Bureau? It's just a position."

"Just irritate me. I've been in the police station for so many years and I haven't even made a deputy. Now you're the chief. Are you going to let people live?"

Lu Guo raised his eyebrows, "I can't help it, the backstage is tough!"

Zhan Honghui snorted, and said in a strange way: "Yes, with a backer as strong as the president, who else can have a backer like you!"

"It's good that you know, let's go, Officer Zhan, and accompany the Landing Bureau to search for evidence. If this case can be closed within three days, then I will apply to the President to let you be my deputy."

"Really?"

"What do you say?"

Zhan Honghui said disdainfully: "Who cares about being your deputy! When you were in the army, you were on top of your head, and you still want to be on top of me for the rest of your life?"

"Then you mean that you plan to be a junior section chief for the rest of your life? Wouldn't you still be overwhelmed by me? So you might as well choose an older official, what do you think?"

"Don't be complacent, kid! The case won't be solved within three days, and you, the chief of the bureau, will be gone. I'll see if you're still talking about it then!"

The reason why Lu Guo dared to release Lu Chuyi and take him home was that he made a promise with the President that there would be two.

First, he guaranteed that Lu Chuyi was innocent and that it was absolutely impossible for him to kill someone.

Second, he promised to solve the case within three days and catch the murderer.

If the case cannot be solved within three days and the murderer cannot be caught, not only will Lu Chuyi be locked up again for interrogation, but he will also be dismissed.

Lu Guo didn't take it seriously, three days was a long time for him, three days and 72 hours, he could do a lot of things.

Moreover, the clock is at 11 o'clock tonight, that is to say, it is now 1 hour earlier, and he has 73 hours, so he is afraid that he will not be able to solve the case?
Walking into the laboratory building, Lu Guo was not in a hurry to check the scene, but first walked around the hall on the first floor, and then went up to the second, third, and fourth floors without stopping. Floor, all the way to the eighth floor.

The laboratory building has a total of eight floors. After reaching the eighth floor, Lu Guo went up to the roof again.

Standing on the rooftop, he asked Zhan Honghui, "Have you been here before?"

"No."

"Do you think there is anything suspicious here?"

Zhan Honghui looked around, and his eyes fell on a building adjacent to the laboratory building. The distance between the two buildings was only about 5 meters. If there was a cableway, it would be a breeze to get from the laboratory building to another building. 5 Meters are not far at all.

"Everyone who enters the laboratory building can find out the time of departure in the monitoring, and conversely, all those who leave can also find the time when they entered the laboratory building that day. I calculated that there are a total of 305 person-times, which is not too many, but Among these people, there is no record of Shang Linru's entry and exit, but she appeared in this building and died in this building, don't you think it's strange? Did this person appear out of thin air?"

"what do you mean……"

Zhan Honghui stared at the adjacent building in surprise for a full minute, then turned his head to look directly at Lu Guo, and stretched out his thumb, showing sincere admiration.

He thought that he had checked all the suspicious points and that there were no problems in all the places, but he ignored the rooftop and all the people who entered and exited the laboratory building.

"Captain, it seems that you have already made preparations before you came."

Lu Guo curled his lips, "Before you came, I went to the building opposite, and the building manager told me that the roof is usually locked, but when he patrolled the building this morning, he found that the door lock was actually open. Yes, he didn't care, thinking that another administrator forgot to lock it after going up to the roof during his rest yesterday, so he locked the door again, and I went to the roof to see."

"What did you find?"

"There are footprints of at least three people, and one of them has the same shoe size as Shang Linru, but it is still not certain that it is Shang Linru."

Zhan Honghui was silent, feeling that he was wasting time and occupying resources by staying in the criminal investigation department for so many years.

After a long time, Zhan Honghui said: "Captain, why don't I be your assistant in the future? I won't be the section chief either."

Lu Guo turned his head to look at him, "Why?"

"Learn from you! I don't think I'm suitable to stay in the criminal investigation department anymore."

"Then you have to think about it. Being an assistant to the Land Bureau is not as good as your section chief."

"The case can't be solved, what kind of scenery do I want!"

"talk later!"

Lu Guo took a flashlight and walked on the roof while observing. As he thought, the footprints on the roof were cleaned up without leaving any traces.

but……

The flashlight in Lu Guo's hand fell on an irregular circular hole on the railing of the roof, and there were scratches around the hole.

"Come and see what this is."

Zhan Honghui stepped forward, his eyes froze, and then exclaimed: "It's so professional!"
